However many companies still impose the maximum hardness defined in NACE MR0175. This varies between 28 – 32 HRc max, depending on the grade and environmental conditions. The impact toughness values shown are those typically specified for the grade The grade consists of a ferrite – austenite phase balance, with typically ferrite being specified in the range 40 – 60 %. Care is required when heat treating large sections, or welding this grade as deleterious precipitation (such as sigma) phase may occur. This results in a significant reduction in corrosion resistance and impact toughness. The grade may be welded, however care is required to ensure the correct phase balance, and to avoid deleterious phases being formed. The excellent corrosion resistance of these grades means that they are used in severe environments, for applications such as piping, valves, fasteners, F53 Flange and other pressure containing items. Care is required when using the grade in conjunction with cathodic protection, due to concerns over hydrogen embrittlement, and it is advised that industry guidelines (such as those given in EEMUA 194) are followed in these applications.

Copper nickel alloys comprise 2 to 30% nickel and have high oxidation resistance and stress corrosion cracking resistance. Their high oxidation resistance is seen in moist air and steam. These alloys are thermally stable and possess moderate strength even when the temperature is high. The corrosion resistance and strength of these alloys are improved by the addition of manganese, iron, niobium, and or chromium. Copper nickel alloys also have good fabricability and high inherent resistance to biofouling. The soluble nature of nickel in copper provides the copper nickel alloys with single phase alpha structures. The alpha dendrites in the cast structures contain a large amount of nickel starting from the center up to the edge of the dendrite. A large quantity of nickel is also present in interdendritic regions. The dendrite structure is broken by mechanical treatments. The alloying elements do not get homogenized even by repeated thermal and mechanical treatments. Copper nickel alloys are of two types that include 70/30 and 90/10. The 70/30 copper nickel alloys have great resistance to sea water-related corrosion due to the presence of significant amounts of manganese and iron. Copper nickel alloys are used in the following areas: Desalination units Hydraulic lines Fish cages for aquaculture Heat exchangers and condensers Nickel Alloy Pipes for sea water pipework Offshore fire water systems Tubes for power plants and ships Pumps, valves, sheathing and fittings for ship hulls Chemical Composition The chemical composition of UNS C71500 copper nickel alloys Tubes are outlined in the following table.ElementContent (%)Copper, Cu70.0Nickel, Ni30.0 Physical Properties The following table shows the physical properties of UNS C71500 copper nickel alloys Tube.PropertiesMetricImperialDensity8.94 g/cm30.323 lb/in3Melting point2140°F1171°C Mechanical Properties The mechanical properties of UNS C71500 copper nickel alloys Tubes are displayed in the following table.PropertiesMetricImperialTensile strength, ultimate372-517 MPa54000-75000 psiTensile strength, yield (depending on temper)88.0-483 MPa12800-70100 psiElongation at break (in 381 mm)45.0%45.0%Charpy impact107 J78.9 ft-lbMachinability (UNS C36000 (free-cutting brass) = 100%)20%20%Shear modulus57.0 GPa8270 ksiPoisson’s ratio0.340.34Elastic modulus150 GPa21800 ksi Other Designations Equivalent materials to UNS C71500 copper nickel alloys Tubes are:ASME SB111ASME SB171ASME SB359ASME SB395ASME SB466ASME SB467ASME SB543ASTM B111ASTM B122ASTM B151ASTM B171ASTM B359ASTM B395ASTM B432ASTM B466ASTM B543ASTM B552ASTM B552ASTM B608ASTM F467ASTM F468DIN 2.0882MIL C-15726MIL T-15005MIL T-16420MIL T-22214SAE J461SAE J463 Fabrication and Heat Treatment Annealing UNS C71500 copper nickel alloys Tubes are annealed at temperatures between 649 and 816°C (1200 and 1500°F) Cold Working UNS C71500 copper nickel alloys Tubes have good cold working capacity.

Stainless steel 410/420, also known as UNS S41000 and UNS S42000, is considered a basic martensitic stainless steel. Comprised of 11.5% to 13.5% chromium and iron, along with trace amounts of other elements including carbon, manganese, phosphorus, silicon, and sulfur. After heat treatment, Stainless Steel 410 exhibits high mechanical properties, it is magnetic in both hardened and annealed conditions. Upon specification, Stainless Steel 410 can be delivered in a hardened, yet still machinable state for uses where moderate corrosion resistance and high strength are required. Stainless Steel 410 reaches maximum corrosion resistance when hardened, tempered and polished. It can be welded using most common welding methods, hot worked between 2000° F and 2200° F, as well as, cold formed and annealed. Because of all of these traits it is widely considered the “general purpose grade” of stainless steel. UNS S42000, commonly known as Stainless Steel 420 is the high carbon content version of Stainless Steel 410. Corrosion resistance is similar between the two, but Stainless Steel 420 additionally provides increased strength and hardness. Like Stainless Steel 410 it is also considered a “general purpose grade” including at least 12% chromium, which is enough to give it acceptable corrosion resistance. Typically, Stainless Steel 420 achieves its best corrosion resistance when the alloy is hardened and polished, or surface ground. Industries that use 410 & 420 include: Automotive Dental/Medical Electrical Food processing Forging Petrochemical Tool Tractor Products partially or completely constructed of 410 & 420 include: Bearings Bushings Cutlery Dies Fasteners Hand tools Plastic molds Pump shafts Screens Steam/Gas Surgical instruments Turbine blades Valves/Valve components Applications Pump Shafts Valve Components Gas and Steam Turbine Components Stainless Steel 410 Flanges & 420 Stock Blind Flanges Lap Joint Flanges Weld Neck Flanges Slip On Flanges Plate Flanges Stainless Steel 420 Pipes & 420 Stock Welded Steel Pipes Seamless Steel Pipes Heat Exchanger Tubes ERW Pipes Cold Draw Seamless Pipes Stainless Steel 410 Pipe Fittings & 420 Stock Butt Welding Fittings Forged Fittingss Equal Tee Reducing Tee Concentric Reducer The information above is not warranted, guaranteed, or for design purposes.

Stainless steel pipe is the perfect solution if you’re looking for material that is resistant to oxidation and is low maintenance. Also when this material comes into contact with other metals, there is no effect on either component. Stainless Steel is the perfect choice for our busy ship channel as it works well for shipping vessels and convenient due to location. Stainless steel pipe can also be used in countless other applications as is discussed below. Types broken down per industry: stainless steel pipe wilsonpipeline. A Brief Overview To be honest, knowing what to buy is a bit more complicated than just knowing what the end use will be. First, know that this material is classified by grade and type. Grade can be adjusted by overall strength, heat resistance, and additives that are used in the material, such as molybdenum or nickel. 304 stainless steel pipe is the most commonly used pipe due to its chemicals and corrosion resistance. 304, however, doesn’t work well with temperatures 800 degrees+ Fahrenheit because of carbide precipitation. Type 304L fixes this problem with its lower levels of carbon. This material is used in higher temperature environments and is perfect for welding. Perfect for Corrosion and High Pressure If corrosion is your biggest challenge, then ferritic or martensic products with high levels of chromium will be your best choice. Austentitic stainless steel pipe has a higher level of nickel and chromium that can offer even more resistance. This piping type is either made from a nickel/chromium combo or from solid chromium. This material is great for corrosive or high temperature environments. Seamless and welded ferretic and austentic pipe are two great examples. Hydraulic Line Tubing Hydraulic line tubing is used for hydraulic systems and fuel lines, tending to be smaller in diameter. This type can be made from the 304 and 304L piping types discussed above. It’s effective in these applications due to its high strength and corrosion resistance. Stainless Steel Sanitary Tubing Without proper sanitation, drinking water as we know it would not be safe to drink. The great thing about stainless steel is that it won’t rust. It resists corrosion and best part is it’s easy to clean. Mechanical Steel Tubing Stainless steel can be found in many implementations including bearings, cylinders, and other formed parts that are similar. A variety of cross-sectional shapes including round tubing can be created. Knowing the requirements for your project first is key to a successful project, whether you need stainless steel pipe or any type of material.

duplex stainless steel. This innovative boat is constructed completely out of stainless steel and can withstand harsh winter weather conditions. This boat measures 10.5m in length and was built in Gävle, Sweden. Our company supplied around 5t of its super duplex 2507 stainless steel, from its Swedish units in Avesta, Degerfors and Nyby for constructing the boat. Commonly boats are produced using glass fiber or carbon steel which requires a lot of maintenance in the form of painting. With the use of stainless steel, no maintenance activities are required. Additionally, thanks to the high strength of duplex, considerable weight savings in the boat structure were achieved since thinner material could be used. SSY follows a patented construction process, which was used along with the super duplex stainless steel 2507. This allowed the fabrication of the boat’s hull to be very thin, without affecting its strength. When powerful waves put pressure on the boat’s hull, it moves controllably, due to the specific type of construction which enables progressive flexibility. Håkan Rosén of SSY, stated that the company succeeded in building a boat completely out of stainless steel, while honoring the Gävle region’s shipbuilding history. This stainless steel boat made its maiden voyage on the 27 July 2014. wilsonpipeline Pipe Industry Co., Limited

You might be thinking right now, why is this important. Why should you learn the proper way to measure the diameter of a stainless steel flange ? I mean after all how hard could it be to figure it out on your own. Well take a second to realize that there’s a lot at stake here. You’ve got equipment that’s incredibly expensive that I’m sure you don’t want to damage and your crew’s safety you have to take into consideration. So, taking a second to read this article and learn how to measure the diameter of a stainless steel flange the right way. This will save you lots of money and heartache down the road. First, Consider Your stainless steel flange Here’s a quick overview for those who may not have experience with stainless steel flanges. stainless steel flanges are basically circular pieces that join two pipes together. The materials that can be used to make stainless steel flanges include: galvanized steel, stainless steel, PVC, etc. They prevent leaking fluids with the seal that they create. Although there are many measurements to take into consideration with a stainless steel flange, a stainless steel flange’s diameter is by far the most crucial when you are lining up one of these in your system. So Let’s Get Started – The Details Are Crucial There are simply 3 steps that are required to measure the diameter of a stainless steel flange properly. Here they are: Step 1: Let’s begin with measuring inside the stainless steel flange with your stainless steel flange’s center hole. The great thing is this will help you determine the size of the pipe that should be paired with your stainless steel flange. Now, if you have documentation on the inside pipe and stainless steel flange measurements, make sure to verify that these measurements are accurate. Step 2: Now you need to take a measurement across the stainless steel flange’s center. You need to find the precise center to get the accurate dimension. Take note of the bolt holes that are around the stainless steel flange. This should help you find the stainless steel flange’s center. Step 3: Now it’s time to take a measurement of the stainless steel flange’s outside diameter. If your stainless steel flange is too dense, you might run into problems and may have to move around some pipe, especially if you’re working with tight spaces. Being conscious of the outside diameter of the stainless steel flange will be of help to you when making your plan. So the three steps above are really all you need to understand to be able to measure thediameter of your stainless steel flange properly. It’s facile to skip one of the steps above with false confidence, but following the steps above to a stainless steel tee will provide an excellent installation. If this is a brand new system you are creating, you could buy all of the stainless steel flanges of stainless steel pipes manufactured together. Dealing with the right company who can provide this for you will eliminate any room for error. Also another thing to take into consideration is that you need to know the fluid type going through your system and the fluid’s temperature, the weather conditions, and the material that the stainless steel flange is made of. Some materials and chemicals just don’t work together.

Stainless Steel Grade 310 is a medium carbon austenitic stainless steel, for high temperature applications such as furnace parts and heat treatment equipment. It is used at temperatures up to 1150°C in continuous service, and 1035°C in intermittent service. Stainless Steel Grade 310S is a low carbon version of grade 310. Typical Applications Stainless Steel Grade 310/310S is used in fluidised bed combustors, kilns, radiant tubes, stainless steel u tube, tube hangers for petroleum refining and steam boilers, coal gasifier internal components, lead pots, thermowells, refractory anchor bolts, burners and combustion chambers, retorts, muffles, annealing covers, saggers, food processing equipment, cryogenic structures. These grades contain 25% chromium and 20% nickel, making them highly resistant to oxidation and corrosion. Stainless Steel Grade 310S is a lower carbon version, less prone to embrittlement and sensitisation in service. The high chromium and medium nickel content make these steels capable for applications in reducing sulphur atmospheres containing H2S. They are widely used in moderately carburising atmospheres, as encountered in petrochemical environments. For more severe carburising atmospheres other heat resisting alloys should be selected. Grade 310 is not recommended for frequent liquid quenching as it suffers from thermal shock. The grade is often used in cryogenic applications, due to its toughness and low magnetic permeability. In common with other austenitic stainless steels, these grades cannot be hardened by heat treatment. They can be hardened by cold work, but this is rarely practiced. Fabrication Stainless Steel Grades 310S/310 are forged in the temperature range 975 – 1175°C. Heavy work is carried out down to 1050°Cand a light finish is applied to the bottom of the range. After forging annealing is recommended to relieve all stresses from the forging process. The alloys can be readily cold formed by standard methods and equipment. Machinability of Stainless Steel Grade 310/310S Stainless Steel Machinability Stainless Steel Grades 310/310S are similar in machinability to type 304. Work hardening can be a problem and it is normal to remove the work hardened layer by using slow speeds and heavy cuts, with sharp tools and good lubrication. Powerful machines and heavy, rigid tools are used. Welding Stainless Steel Grades 310/310S are welded with matching electrodes and filler metals. The alloys are readily welded by SMAW (manual), GMAW (MIG), GTAW (TIG) and SAW. Electrodes to AWS A5.4 E310-XX and A 5.22 E310T-X, and filler metal AWS A5.9 ER310 are used. Argon is shielding gas. Preheat and post heat are not required, but for corrosion service in liquids full post weld solution annealing treatment is essential. Pickling and passivation of the surface to remove high temperature oxides are essential to restore full aqueous corrosion resistance after welding. This treatment is not required for high temperature service, but welding slag should be thoroughly removed. Stainless Steel Grades 310/310S have good resistance to oxidation in intermittent service in air up to 1035°C and 1050°C in continuous service. The grades are resistant to oxidation, sulphidation and carburisation. Available Forms of Grade 310/310S Stainless Steel wilsonpipeline Pipe Industry can supply these grades as stainless steel plates, stainless steel sheets and stainless steel strips, stainless steel bars and stainless steel rods, seamless stainless steel tubes and seamless stainless steel pipes, welded stainless steel tubes andwelded stainless steel pipes, stainless steel forgings and stainless steel forging billets, stainless steel tubes and stainless steel pipe fittings,stainless steel wires. Corrosion Resistance Stainless Steel Grade 310/310S is generally not used for corrosive liquid service, although the high chromium and nickel content give corrosion resistance superior to grade 304. The alloy does not contain molybdenum, so pitting resistance is quite poor. Stainless Steel Grade 310/310S will be sensitised to intergranular corrosion after service at temperatures in range 550 – 800°C. Chloride stress corrosion cracking may take place in corrosive liquids containing chlorides at temperatures exceeding 100°C.

Sometimes your pipeline may need to be put on hold temporarily or maybe even permanently. This is where duplex stainless steel blind flanges come in handy. These duplex stainless steel flanges can be used to build a pipeline and they can be used to repair a pipeline to stop fluid from flowing. These can also be utilized to discontinue a pipeline without causing any damage to the pipeline itself. So How Are They Put Together? Good question! Typically, these duplex stainless steel flanges are constructed just like any kind of duplex stainless steel flange with mounting holes that goes around the circumference of the gasket seal and pipe and are then machined into the surface. Take into consideration that a blind flange doesn’t have any openings that will allow to fluids to go through. The duplex stainless steel flange’s face is either raised or flat, all depending on how the system is designed or the preferences of an engineer. You should consult with your supplier for advice and specifics on how to install your duplex stainless steel blind flanges. It’s also a great idea to buy these duplex stainless steel flanges while you are still in the process of installing your system, so you can ensure the proper fit for your system, avoiding expensive repairs in the future. How to Find the Right Size You need to find the right size to ensure that a successful seal is made. Leaks will happen if you do not take this into consideration. You need to understand the standards that are being used. Consult with a good system designer or a vessel engineer. They know the standards. Remember that there are many engineering standards utilized to manufacture duplex stainless steel flanges that ensure consistency. These standards size, dimension, pressure, how components are created, and control the quantity of holes to be installed onto the surface. Most manufacturers of this material either use ANSI (American National Standards Institute), JIS (Japanese Industrial Standards), and DIN (German Institute for Standardization). Measurement of Duplex Stainless Steel Blind Flanges Being conscious of the right standard will help you determine the correct measuring tool to use when determining the size of your duplex stainless steel flanges. Use the right system of measurement. Remember that metric doesn’t convert to inches. So what you need to do now is measure the outside and inside diameters of your pipeline. Inner diameter is crucial due to the fact that duplex stainless steel flanges normally have an equivalent pipe size as specified by accepted standards. The pipe that’s connected should fit inside your duplex stainless steel blind flanges. When constructing your system, you need a universal or common design. As long as the proper diameter and standards are put into practice, any duplex stainless steel pipes may be used with any pipeline.
