  • the type of flange sealing surface

    What is gasket  ? Cangzhou wilson pipeline  sales@wilsonpipeline.com The contact surface where the gasket is inserted between the flanges and pressed to achieve the sealing effect is called the flange sealing surface or pressing surface.The choice of sealing face type depends on operating conditions, the consequences of leakage, and the nature of the gasket.The common types of structures are as follows. 1   Flat sealing surface  : the sealing surface is not a smooth plane.There are usually 2 to 4 concentric triangular cross-section grooves (i.e. flanged waterline) in the plane.Plane sealing surface structure is simple, easy to manufacture, easy to corrosion-resistant lining.Secondly, the width of the sealing surface of this structure is large, so non-metal or metal soft gaskets are often used in use.But when the bolts are tightened, the gasket material can easily stretch to both sides.Applicable to the pressure requirement is not high, non-toxic medium occasions. 2   Concave-convex sealing surface  : It is equivalent to a pair of flat sealing face flanges, one of which is made into a pressing surface with a raised platform, called a flange, and the other is correspondingly made into a concave flange, called a concave flange.The same size gasket as the concave type is embedded, and the gasket is easily centered.The height of the convex surface is slightly greater than the depth of the concave surface, and the bolt is pressed tightly to play a sealing role.This structure can limit the radial deformation of the gasket, prevent the gasket from being squeezed, and improve the sealing performance to a certain extent.Suitable for high pressure occasions. 3    Tongue and groove sealing surface  :  in the middle of a pair of flat sealing surfaces in the width direction, one is made into a cross-section like a tenon, and the other cross-section is like a groove. The pressing surface is paired the former is called a tenon surface flange, the latter is called groove flange. The groove-shaped pressing surface can limit the radial deformation of the embedded gasket, with good sealing performance, and the gasket can be less eroded and corroded by the medium. But the tenon part is easy to damage. It is often used in flammable, explosive, toxic media and higher pressure occasions. In addition, there are trapezoidal groove sealing surfaces and tapered sealing surfaces. The former uses an elliptical cross-section annular metal gasket, and the latter uses a lens-type annular metal gasket. The above two structures are forced sealing, which are commonly used on high-pressure pipelines.The form and surface properties of the flange sealing surface play a vital role in the influence of the sealing effect. The flatness of the flange sealing surface and the perpendicularity between the sealing surface and the flange centerline directly affect the uniformity of the gasket force and the good contact between the gasket and the flange.

  • how to introduction of fracture inspection

    The fracture inspection is one of the methods to check the quality of steel pipeline products.Cangzhou wilson pipeline  sales@wilsonpipeline.com There are mainly the following fracture types: ductile fracture, brittle fracture, porcelain fracture, lamellar fracture, stony fracture, graphite fracture, etc. Besides, according to the different types of steel and inspection requirements, the fracture test sample should be subjected to different heat treatment before breaking. According to the different heat treatment methods, the fracture can be divided into: promoting fire fracture, annealing fracture, tempering fracture, etc. The role of fracture inspection: The broken test piece can be matched with the transverse low-power tissue to check the defects of the steel.The fracture can directly show white spots, inclusions, bubbles, internal cracks, residual shrinkage holes and other defects in steel.By identifying the size and characteristics of the grain on the fracture, the situation of overheating or overburning of steel can be determined, the fracture characteristics of steel can be determined and the fracture reason of steel can be judged. Fracture inspection does not require any preparation of specimens, and can be directly observed and tested. Direct observation of these natural surfaces can be made to obtain direct data.It is suitable for parts and parts that are damaged in the process of use, as well as parts that are damaged due to some reason in the process of production and manufacturing.

  • How the PWHT work?

    Post weld heat treatment (PWHT) process refers to a welding heat treatment process in which the welds are heated to a certain temperature and held for a certain period of time after the completion of the welding work, so that the welds cool down slowly to improve the microstructure and properties of the welded joints or eliminate residual stress.Post-welding heat treatment process generally includes three processes: heating, heat preservation and cooling. These processes are interconnected and uninterruptible. Selection of heat treatment methods Post-welding heat treatment generally uses a single high temperature tempering or normalizing and high temperature tempering treatment.For the gas welding joint using normalizing and high temperature tempering heat treatment.This is because the grain size of the welding seam and heat affected zone of gas welding is coarse, and the grain size needs to be refined, so normalizing treatment is adopted.However, single normalizing can not eliminate residual stress, so it is necessary to add high temperature tempering to eliminate stress.The single medium temperature tempering is only suitable for the assembly and welding of large ordinary low carbon steel vessels assembled on site, which aims to partially eliminate residual stress and dehydrogenation.The vast majority of occasions are to choose a single high temperature tempering.The heating and cooling of heat treatment should not be too fast, and the inner and outer walls should be uniform. he heating method of post welding heat treatment (1) induction heating.Steel produces induction potential in the alternating magnetic field, and the effect of eddy current and hysteresis makes steel heat, that is, induction heating.Now the project mostly uses simple power frequency induction heating equipment. ⑵ Radiative heating.Radiative heating is the radiating of heat from a heat source to a metal surface, and then the metal surface conducts the heat in other directions.Therefore, the temperature difference between the inner and outer walls of the metal is great during the radiation heating, and the heating effect is worse than that of the induction heating.Radiative heating commonly used flame heating, resistance furnace heating, infrared heating method.

  • How the effect arise when forging is quenched and cooled?

    Next, let’s learn about the quality problems and solutions of forgings in quenching and cooling:Cangzhou wilson pipeline  sales@wilsonpipeline.com Insufficient hardness and enough hardening depth: quenching cooling rate is low is forging quenching hardness is insufficient, the cause of the uneven hardness and hardening depth is not enough, but, according to the actual quenching forging materials, shape, size and heat treatment requirements, and can be divided into high temperature stage of insufficient cooling speed and cooling speed in low temperature stage and different situation such as insufficient cooling speed and low temperature stage.For example.For small and medium forgings, the insufficient quenching hardness is often caused by the insufficient cooling rate in the middle and high temperature stage, and when the forgings with large modulus require a deeper quenched layer, it is necessary to increase the low temperature cooling rate.For quenching oil, generally speaking, the steam film stage of oil is short, the cooling rate of medium temperature is fast, and the cooling rate of low temperature is fast, so it can often obtain high and uniform quenching hardness and enough quenching depth. High core hardness after quenching: this kind of problem may be related to the selected medium cooling rate too fast or the medium low temperature cooling rate is too high.One solution is to change the quenching oil to meet the requirements.The other way is to contact the quenching medium manufacturer and add appropriate additives to reduce the cooling rate of the quenching oil at medium and low temperature.The third way is to use steel with lower hardenability.

  • What To Always Check When You’re In Need Of A Plumber

    Plumbing issues are frustrating and can cost a lot of time and money to fix. Some problems are too tricky and complicated to handle on your own, while others can be easily fixed with a few do-it-yourself tips. Plumbing issues such as clogged drains can undoubtedly disrupt your everyday activities, and you should always try to resolve your plumbing problems as soon as you can. However, before you decide that you need a plumber, you should always determine what the plumbing issue you are having and whether or not you can tackle it on your own. Here is what you should always check first when you think you may need a plumber. Check if You Can Solve Your Plumbing Problem Yourself You can attempt to fix issues on your own such as leaking sinks, running toilets, and clogged drains. However, there are more challenging issues, such as burst pipes, and there’s no question a professional plumber should handle that. Therefore, before you call a plumber, have a look at your issue and try to understand what the problem is and whether you have the knowledge and skills to solve it. If your sink is leaking, for example, you can try to fix it yourself by trying to identify any parts which have come loose and then try to tighten them up. Another common problem which many people have is a running toilet. To solve this issue, you can try to replace the flapper, the flapper valve, or both. Check for Local Plumbing Services in your Area After you have assessed your plumbing problem and attempted all the home remedies to no avail, it is time to call a professional plumber. It is important that you hire a professional and trustworthy service to avoid wasting your time, money, and effort. Speak to friends and family for recommendations for local plumbers they have used in the past who have delivered a good service. The experts at All Service Plumbers explain that before hiring a plumber or giving them any money, you should check that they have a plumbing license and the necessary insurance to do the job. If you found the plumber on your own without a recommendation, it is advisable to go online to do some research or find at least two references. Additionally, you should check how long your chosen plumber has been in business since reputable businesses typically last for a longer time than unreliable ones. Some Common Plumbing Issues You Might Encounter Check Your Sink For Clogs Aside from leaking sinks and running toilets, clogged drains are among the most common plumbing problems people often face that are more difficult to fix at home. While major clogs often need a professional plumber, minor clogged drains are easier to deal with. In fact, you can try to check whether or not your sink is clogged by pouring water down and seeing if it drains. If your sink is clogged, you can try different approaches, such as flushing your drain out using boiling water. This solution is the quickest, easiest, and most cost-effective way to solve a minor clog. First of all, you should try to remove the standing water in your sink or above the clogged area. After that, try pouring boiling water directly into the clogged drain. Wait for a moment to see whether the water goes down before removing the standing water and trying again. Check If A Plunger Or Coat Hanger Can Unlodge Clogs Even though most people associate plungers with toilets, they can also be very effective with a clogged sink. Fill your sink with hot water up to a quarter of the way up, and then place a plunger over the plughole to work it up and down quickly. Afterward, remove the plunger from the drain and observe whether or not the water starts to drain. Remember that it might take some time and a few attempts for the plunger to unclog your sink successfully. Therefore, repeat this a few times if necessary. As well as a plunger, many people also use a straightened coat hanger to try and reach as far as possible down their clogged drains to fish out the blockage. Check If Your Drains Are Blocked Depending on the blockage scale and the material which has built up, baking soda can be used with either white vinegar or salt to unblock the sink. Typically, all standing water should be removed from the blocked sink or the blocked area. Then, you can pour a mixture of baking soda and white vinegar or salt down the drain. Note that this mixture might cause some bubbly liquid to rise, but if this happens, you can place a sink stopper on top of it or cover your drain with a piece of cloth. This solution should be left in your drain for 10 to 15 minutes before running boiling water down and attempting to flush out the drain. If this doesn’t do the trick, you can use a commercial solution made explicitly for blocked drains. This is widely available in many stores, and you can simply follow the instructions on the product. However, remember to use these solutions carefully to avoid physical harm to yourself or further damages. It is helpful for you as a customer to get competing quotes on a plumbing issue that isn’t too urgent. This allows you to choose the best quality plumbing service at a competitive price. Keep in mind; however, that price does not mean everything, and so the lowest price does not necessarily mean that you will get the best available service. When a plumbing issue arises, sometimes the problem can be solved quickly with simple do-it-yourself tips and solutions. Other times, you will need to hire a professional plumber to save your plumbing system and home from further damage. However, before you call a plumber, remember to check these steps first to make sure that you’re not calling one out for a job that you can easily do. #Plumber #Check

  • Understanding steel grades for piping procurement

    As industrial processes and applications have matured, industry organizations have developed unique classifications and specifications for the pipe destined for service in those sectors. There’s lots of overlap among the organizations’ published specs, and likely lots of confusion as well. Buyers can improve their purchasing experience by learning more about how grades of steel are designated for piping and by understanding all the information that should be included on a purchase order. ASTM and ASME Both the American Society of Testing and Methods (ASTM) and the American Society of Mechanical Engineers (ASME) publish piping specs. ASTM and ASME pipe designations for grades of steel are very similar. For example, A106 B is a spec published by ASTM (the ASME spec would be SA106 B). The “A” designates a ferrous material. ‘106’ is an arbitrary number that designates it as a seamless carbon steel pipe suited for high-temperature service. Then, grades (such as A, B or C) are assigned that indicate certain characteristics of the steel based on differences in its chemical makeup and mechanical properties. Pipe sizes are described by using a pipe chart (ANSI/ASME B36.10 and API5L) that includes the outside diameter and wall thickness. The outside diameter can be referred by the nominal pipe size (NPS) or the actual dimension in inches and the wall by stating the schedule or the actual thickness in inches. Note that while ASTM and ASME specs are largely identical, an important difference is that pipe meant for use in pressure systems sometimes requires different or additional quality tests before it complies with the ASME standard. American Piping Products stocks a full range of A/SA106 and A/SA 53 carbon steel pipe. AISI and SAE The American Iron and Steel Institute (AISI) and the Society of Automotive Engineers (SAE) share a numbering system to classify steels. AISI/SAE designations only describe the chemical makeup of a steel. They do not include manufacturing, heat treating or testing information. Using 1020 steel as an example, the first digit expresses the steel as a plain carbon steel. The second digit indicates there are no added alloys. The last two digits indicate the steel has around 0.20 percent carbon content. For another example, a popular steel in the piping industry is 4130. The ’41’ indicates the steel contains chromium and molybdenum alloys. The ’30’ indicates the steel has around 0.30 percent carbon content. Again, AISI/SAE designations only classify steels. For example, a buyer who says, “I need 100 feet of 4130” has not provided enough information. The buyer also needs to note specific production and testing information found in an ASTM or ASME spec to get exactly the pipe they need. API Pipe for use in the oil & gas industry are classified by the American Petroleum Institute’s (API) system. API 5L is the most common standard to which line pipe in the oil and natural gas industry is rated. Because that’s merely a standard, additional information is needed to ensure purchase orders are executed accurately. API 5L pipe is broken down into PSL1 and PSL2 delivery conditions; those conditions are further broken down into pipe grades, i.e. Grade B, X42, X52, X65, etc. Buyers should include the combination of the overarching standard, the delivery condition and the grade for the API5L pipe they need. Study grades of steel Buyers who place incomplete or inaccurate orders put their operations at risk of delays or cost overruns. When in doubt, consult with an engineer and refer to the industry standards that govern your application. Also be aware of other factors that play into your purchase: What manufacturer restrictions are in place that may impact your order? Are there any origin restrictions that you need to follow when buying? What pipe lengths and end finishes do you need? Are there specific chemistry requirements needed for the application? Are there age restrictions that may impact your order for export? Suppliers need detailed purchase orders to ensure you get the right pipe the first time.

  • Welded vs. seamless steel pipe

    As industrial applications have evolved and grown more complex, the piping products and systems that serve them have had to keep pace. While many pipe manufacturing methods exist, the most prominent discussion in the industry compares electric resistance welded (ERW) vs. seamless (SMLS) steel pipe. Both ERW and seamless steel pipe manufacturing methods have been in use for decades; over time, the methods used to produce each have advanced. So which is better? Manufacturing welded pipe Welded pipe starts out as a long, coiled ribbon of steel called a skelp. The skelp is cut to the desired length, resulting in a flat rectangular sheet. The width of that sheet’s shorter ends will become the pipe’s outside circumference, a value that can be used to calculate its eventual outside diameter. The rectangular sheets are fed through a rolling machine that curls the longer sides up toward one another, forming a cylinder. In the ERW process, high-frequency electrical current is passed between the edges, causing them to melt and fuse together. An advantage of ERW pipe is that no fusion metals are used and the weld seam cannot be seen or felt. That’s opposed to double submerged arc welding (DSAW), which leaves behind an obvious weld bead that must then be eliminated depending on the application. Welded pipe manufacturing techniques have improved over the years. Perhaps the most important advancement has been the switch to high-frequency electric currents for welding. Prior to the 1970s, low-frequency current was used. Weld seams produced from low-frequency ERW were more prone to corrosion and seam failure. Most welded pipe types require heat treatment after manufacture. Manufacturing seamless pipe Seamless piping begins as a solid cylindrical hunk of steel called a billet. While still hot, billets are pierced through the center with a mandrel. The next step is rolling and stretching the hollow billet. The billet is precisely rolled and stretched until it meets the length, diameter and wall thickness as specified by the customer order. Some seamless pipe types harden as they’re manufactured, so heat treatment after manufacturing is not required. Others do require heat treatment. Consult the specification of the seamless pipe type you’re considering to learn whether it will require heat treatment. Historical perspectives and use cases for welded vs. seamless steel pipe ERW and seamless steel piping exist as alternatives today largely due to historical perceptions. Generally, welded pipe was considered inherently weaker because it included a weld seam. Seamless pipe lacked this perceived structural flaw and was considered safer. While it’s true that welded pipe does include a seam that makes it theoretically weaker, manufacturing techniques and quality assurance regimens each have improved to the extent that welded pipe will perform as desired when its tolerances aren’t exceeded. While the apparent advantage is clear, a critique of seamless piping is that the rolling and stretching process produces an inconsistent wall thickness compared to the more precise thickness of steel sheets destined for welding. The industry standards that govern the manufacture and specification of ERW and seamless steel pipe still reflect those perceptions. For example, seamless piping is required for many high-pressure, high-temperature applications in the oil & gas, power generation and pharmaceutical industries. Welded piping (which is generally cheaper to produce and is more widely available) is specified across all industries as long as the temperature, pressure and other service variables do not exceed parameters noted in the applicable standard. In structural applications, there’s no difference in performance between ERW and seamless steel pipe. While the two can be specified interchangeably, it wouldn’t make sense to specify for seamless when cheaper welded pipe works equally well. Good purchasing practice for welded and seamless steel pipe An important note to make as piping products are specified for a project is that the specification books (such as those provided by ASTM, ASME, ANSI and API, among others) that engineers use to guide the specs they write only list pipe grades without referencing whether they’re produced via ERW or seamless pipe manufacturing. Not all grades can be produced by both means. For example, a potential mix-up can occur if an engineer specifies welded pipe with a large outside diameter and wall thickness without knowing it would be impossible to manufacture it. This error would likely go unnoticed until a purchase order is placed, at which time a pipe supplier would notify the customer that the order couldn’t be fulfilled as written. Also, a good grasp of industry standards could lead to cost savings. The A106 and A53 carbon steel pipe standards are a good example. In this article, we discuss how pipe complying with the former must be seamless while pipe complying with the latter can either be seamless or welded. For example, if an engineer must follow the A53 standard on a given project, he or she may still have the flexibility to choose which type to specify based on the specifics of the application.

  • Comparing common steel pipe: A106 vs. A53

    They’re the most commonly used carbon steel pipe types in industry today, and they’re very similar. But while the differences between A106 and A53 are few, they matter a great deal in terms of when and where each is specified. To ensure you purchase the correct pipe and receive it quickly, two things are a must: A basic understanding of seamless and welded seam pipe, and providing detailed specs. A106 vs. A53 — Welded vs. seamless steel pipe If you read the ASTM and ASME standards for A106 and A53 pipe, you’d quickly observe how similar they are in terms of chemical makeup and manufacture. The most important difference is that pipe meeting the A106 standard must be seamless while pipe meeting A53 can either be seamless or welded. Welded seam pipe is made by curling a steel plate into a cylinder and then joining the edges via a weld. Seamless pipe is made by piercing cylindrical bars of steel through the middle while it’s hot, creating the same shape but without a seam. The reason for the difference lies in the suitable applications for each type. A53 pipe is best suited for transport of air, water, steam and oil in low- and medium pressure applications across the industrial spectrum. It’s also commonly used as structural steel. A106 pipe is formulated specifically for high-temperature and high-pressure service, usually in power generation applications. High-pressure, high-heat service environments put added stress on pipe, so seamless pipe types are preferred in those settings since they’re at less risk of failure under stress than their welded counterparts. Differences in chemical makeup In addition to the way the A106 and A53 standards dictate pipe manufacture, the standards feature slight differences in chemical makeup. Refer to our A106 vs. A53 comparison chart to see them all, but the most noteworthy difference is the presence of silicon in A106 pipe and its absence in A53. Silicon as an alloying element improves heat resistance in A106 pipe, which is rated for high-temperature service. Without it, regular exposure to high temperatures can weaken pipe over time, increasing its risk of failure. The A106 and A53 standards also include varying amounts of sulfur and phosphorus depending on the grade. These elements are normally considered impurities in steel, so their incorporation in piping is minimal. However, the trace amounts of these elements add machinability to steel pipe. Purchasing A106 vs. A53 When buying A106 or A53 carbon steel pipe, clarity is the most important factor. Usually whoever does the actual purchasing is not a piping expert. They’re often buyers working from a document provided by an engineer. In cases where specs are not clear, a pipe seller can help a buyer determine what is needed by asking questions. However, this can take added time and the buyer may not know the answers. The pipe sale quickly turns into a game of phone tag. To avoid this, buyers should make sure specs are crystal clear. Also, keeping good records will add efficiency to piping procurement. If a firm regularly purchases A106 or A53 pipe, that information should be kept handy as a reference. At Wilson pipelline Products, our piping experts are trained to assist buyers in determining whether A106 vs. A53 is the right pipe for their application.

  • Standards organizations impacting steel piping: ASTM vs. ASME vs. API vs. ANSI

    Standards and industry go hand in hand. You can’t have one without the other. Because pipe is so common among so many industries, it’s no surprise that a number of different standards organizations impact the production and testing of pipe for use across a wide array of applications. As you’ll see, there’s both some overlap as well as some differences among the standards organizations that buyers should understand so that they can ensure accurate specs for their projets. ASTM ASTM International provides industrial material and service standards across a wide range of industrial sectors. The organization has published more than 12,000 standards currently in use in industries worldwide. More than 100 of those standards pertain to steel pipe, tubing, fittings and flanges. Unlike some standards organizations that impact steel pipe in specific industrial sectors, ASTM standards cover a wide variety of pipe used in just about every industry you can think of. For example, American Piping Products stocks a full range of A106 pipe. The A106 standard covers seamless carbon steel pipe for high-temperature service. That standard does not necessarily limit pipe to any certain industrial application. ASME The American Society of Mechanical Engineers began publishing standards for industrial tools and machine parts in 1880 and has been a driving force behind safety improvements to boilers and pressure vessels used across industrial sectors. As pipe commonly accompanies pressure vessels, ASME standards cover a wide variety of pipe applications across many industries, same as ASTM. In fact, the ASME and ASTM pipe standards are largely identical. Any time you see a pipe standard expressed with both an ‘A’ and an ‘SA’—an example is A/SA 333—it’s a sign that the material meets both the ASTM and ASME standards. API As its name indicates, the American Petroleum Institute is an industry-specific organization that, among other things, develops and publishes standards for pipe and other materials used in the oil & gas industry. Piping rated under an API standard can be very similar in material and design to pipes used in other industries under other standards. API standards are more strict and include additional testing requirements, but there is some overlap. API 5L pipe, for example, is commonly used in oil & gas settings. The standard is similar to A/SA 106 and A/SA 53. Some grades of API 5L pipe comply with the A/SA 106 and A/SA 53 standards and therefore can be used interchangeably. But A/SA 106 and A/SA 53 pipe do not comply with all API 5L criteria. ANSI The American National Standards Institute was founded following a gathering of several industry standards organizations in 1916 with the goal of developing voluntary consensus standards in the U.S. ANSI joined with similar organizations in other countries to form the International Organization for Standardization (ISO). The Organization publishes standards accepted by industrial stakeholders from across the world. ANSI also acts as an accrediting body that endorses standards developed by individual organizations for worldwide adoption. Many ASTM, ASME and other standards have been endorsed by ANSI as acceptable common standards. One example is the ASME B16 standard for flanges, valves, fittings and gaskets. The standard was initially developed by ASME, but it’s been endorsed for use worldwide by ANSI. ANSI’s efforts have helped open international markets for producers and suppliers of pipe due to its role in the development and adoption of common standards accepted globally. The right pipe supplier With decades of experience supplying pipe to customers of all industries all over the world, American Piping Products understands the complexity —and the importance— of the many standards that govern the production and testing of pipe. Let us use that experience for the good of your business. By choosing American Piping Products as your supplier, you can focus on what matters most to you instead of getting bogged down in the details. We’ll handle that. #Training #equipment
