First, the advantages and disadvantages of stainless steel pipe fitting is introduced The advantages of stainless steel pipe fittings are as follows: the advantages of such as stainless steel elbow, tee, stainless steel pipe fittings due to easy to clean, beautiful appearance, does not rust and is widely used in various industries. The disadvantage of stainless steel pipe fittings are as follows: poor heat transfer, unless for bonded aluminum or copper base, thermal conductivity is very poor. This means that a cheaper stainless steel pipe fittings are not necessarily better than other products. Price is quite high, the stainless steel cookware is very good, can last a lifetime of time, many people think that this is a one-time purchase, worth the investment. Second, the Stainless steel pipe fittings welding technical requirements Due to the Stainless steel pipe fittings sizes, according to the welding of stainless steel pipe fittings unique place, as far as possible reduce the amount of heat input, the manual electric arc welding, argon arc welding is adopted two kinds of methods, d > Φ 159 mm adopts argon arc welding, manual arc welding surface. D ≦ Φ 159 mm all use argon arc welding. Stainless steel pipe fittings welding technical requirements are as follows: 1, manual electric arc welding, welding machine adopts dc reverse connection, when using dc argon arc welding is pick up; 2, before welding wire should be used on the surface of the stainless steel wire brush to brush off the scale, with acetone to wash; Electrode should be in 200-250 ℃ drying 1 h, as you take; 3, the workpiece before welding groove on both sides of the 25 mm within the scope of the clean up oil pollution and so on, with acetone to wash groove on both sides of the 25 mm; 4, argon arc welding, the nozzle Φ 2 mm in diameter, extremely rich tungsten tungsten electrode, specifications Φ 2.5 mm; 5, argon arc welding of stainless steel, the back must fill argon protection, to ensure forming on the back. Using the method of partial argon filling in the pipe flow for 5-14 l/min, positive argon gas flow is 12 13 l/min. Stainless steel pipe fittings in backing welding seam thickness should be thin as far as possible, and the roots of fusion, outstanding to into a gentle slope, arc extinguishing arc extinguishing shrinkage cavity, if any, polishing machine grinding. Must be within the groove arc arc, arc should fill arc crater and prevent the crack of arc crater. Source: wilsonpipeline Pipe Industry Co., Limited (www.wilsonpipeline.com)

Marine standard code-named: ES, this two letters is said Marine short radius elbow, named short elbow bending radius, the same as 12459-2005, just a little 90 degrees. This is a used to ship ventilation pipe flange, three models, use English letters ABC to distinguish between types. Type A is A circular flange, is A big difference with the ordinary flange, outside diameter, all thickness is very thin. Is four thick from DN25 to 150. From five DN175 to DN450 is thick. From DN500 to DN1000 is the thickness of 6. Outer diameter is much smaller. Working pressure is small, 25-400 is less than or equal to 0.20 MPA. Less than or equal to 0.15 MPA, 450-500. 600 to 700 is less than or equal to 0.10 MPA. The 800 to 1000 is less than or equal to 0.05 MPA. The general piping flange minimum pressure 0.25 MPA. Type B is a rectangular flat steel flange, is square. Specifications from 80 to 80 over. Pressure is less than or equal to 0.05 MPA. Type C flange is called A rectangular Angle steel flange, is made of Angle steel, pressure and type A is the same. Marine standard welding short radius elbow is with commonly used pipe welding short radius elbows are distinguished. Marine short radius elbow R (bending radius) is the DN is equal, it of the DN100 nominal diameter, for example, the radius is 100. 125 is 125.300, it’s 300. This kind with standard short elbow ends from 50 to 300. And commonly used short radius elbow is DN100 is 102. The DN125 is 127. 12 is 305. A little larger than the standard all Marine. And on the thickness of the tube, also is not the same as common, the common bend (12459) gives only a pressure rating table. You can choose the thickness. And ship the short radius elbow, direct you thickness is given. From (to 65 are two thickness. From 80 to 200, there are three thickness. In 250 and 300, and only for two thickness.

Stainless steel, it is to point to weak corrosive medium such as air, steam, water resistance and acid, alkali, salt and other chemical etching medium corrosion of the steel, also called acid-proof stainless steel. Stainless steel itself because of its corrosion resistance, high temperature resistant, wear resistant features, in our country focus on the development of energy, petrochemical, electric power, mining and other fields will be more active to play its role. Products include stainless steel flanges and stainless steel pipe fittings. About the stainless steel chemical identification method has the following kinds: 1, magnetic test, magnetic test method is the most primitive of the most common difference between austenitic stainless steel and ferritic stainless steel of the most simple way to austenitic stainless steel, nonmagnetic steel but after cold work under big pressure will be mild magnetic, and pure chromium steel and low alloy steel are strong magnetic steel. 2, nitric acid test points that stainless steel is a striking feature of nitric acid and dilute nitric acid have inherent corrosion resistance, this performance make it can easily distinguish from most other metals or alloys, but high carbon type 420 and 440 steel in nitric acid test is a little corrosion, when meet with nitric acid was immediately non-ferrous metal corrosion, dilute nitric acid on carbon steel has strong corrosive. 3, copper sulfate spot test, the copper sulfate test is quick to distinguish between ordinary carbon steel and the easiest way of all types of stainless steel, the use of the concentration of a solution of copper sulfate is 5% – 10%, before the point tests, test area should be thoroughly remove oil and other impurities, cloth or soft grinding polishing and grinding machine, small area, and then try the droplets to burnish, ordinary carbon steel or iron within a few seconds can form a layer of metal copper surface, and test the surface of the stainless steel is not produced copper precipitation or display the color of copper. 4, sulfuric acid test, acid immersion stainless steel can make a distinction between 302 and 304 and 304 and 316. Sample trimming should pass fine grinding, and then in the volume concentration of 20% ~ 20%, the temperature of 60 ~ 66 ℃ in sulfuric acid cleaning and passivation for half an hour, the volume concentration of the sulfuric acid solution was 10%, when heated to 71 ℃, 302 and 304 in solution in stainless steel corrosion was quickly and produce a large number of air bubbles, sample in some kind of black, the 316 and 317 stainless steel sample was from corrosion or corrosion slow (not have bubbles), test does not change color within 10 ~ 15 minutes. If at the same time test specimen with a known component is used to compare similar words, can make the experiment more accurate.

How to detect whether the stainless steel elbow is corroded? stainless steel elbow after corrosion, usually The thickness of the stainless steel elbow has thinned, stainless steel elbow appears on the surface of pits and pitting. Now stainless steel elbow corrosion detection method is widely used at home and abroad is the method of magnetic flux leakage and ultrasonic test. (1) the method of ultrasonic, ultrasonic testing technique is to use ultrasonic pulse reflection principle to measure the thickness of pipe wall corrosion after. Detection will launch ultrasonic pulse probe perpendicular to the stainless steel elbow wall, probe first received by the inner surface of tube wall reflection pulse, then ultrasonic probe will receive from the reflection of the surface outside wall pulse, the pulse and the distance between the internal surface reflection pulse spacing reflects the thickness of tube wall. (2) the magnetic flux leakage method, the basic principle of magnetic flux leakage method is based on the high permeability of the properties of ferromagnetic materials, stainless steel elbow corrosion defect of permeability is far less than the permeability of stainless steel elbow, stainless steel elbow in the applied magnetic field under the action of magnetized, when no defect of the bend, for the most part lines by steel tube, the lines of magnetic force uniform distribution; When bend internal flaws, the lines of magnetic force bent, leaking pipe surface and a part of the field lines. Escape detection by magnetization bend surface of magnetic flux leakage, can determine whether defects exist. Source: wilsonpipeline Pipe Industry Co., Limited (www.wilsonpipeline.com)

To opposite stainless steel flanges parts have a certain understanding of this, we must first know what to do with the stainless steel flange is used substances. Our life stainless steel flange not familiar, but we have already heard the pipe should be. Under normal circumstances, a section of the pipe is in our lives, but when we use specific, often need to turn a section of the pipe connecting use, and regular connection pipe means, we need to use the method Lan this matter. We will first introduce the relevant knowledge. Stainless steel flange’s part, we can usually called stainless steel flange blue plate or stainless steel flange, for ease of installation, you need to leave the perforations on the edge of this part of the stainless steel flange, use the time to pairs of use, that is to say in two pipe breakage segment of the mounting piece, and then after two stainless steel flanges pigeon, in a tight two-piece bolted flange, in order to make more airtight, under normal circumstances but also between the two flanges pad liner. Two flange connection method called wire flange, another method known welding flanges. Here there is a major role on what to talk about welding flange, First, this effect can be said to be relatively straightforward, since the flange is used to connect the pipe parts, so the main effect of stainless steel flange is used to connect pipes and stainless steel flange connections can use the greatest degree of assurance sealing performance pipeline. Secondly, we all know that no matter how good things long time, and there will be problems, if there are problems need to be replaced, and the use as a connecting stainless steel flange parts, there is a huge role is to facilitate the replacement of a problem pipeline. You can also say that the use of flange-mounted pipeline both easy to install and also easy removal. The third point, then there is in the case does not affect the use of the pipeline routine inspections in order to timely identify and solve problems, but also to avoid problems. On the other hand, also describes the use of stainless steel welded pipe have any good ways to connect. It needs to be emphasized here is that some large pipeline installation, using this method as the connection method, the construction will bring more convenience. And in this case, stainless steel welded flange connection method, check the work will bring greater convenience. wilsonpipeline Pipe Industry Co., Limited (www.wilsonpipeline.com)

plug pipe can withstand high pressure, it is connected with the main parts of the pipe, it can be used in different forms, different connection types, they are not the same as the level of pressure, the type is many, there are different angles of elbow, there are four, three and so on, but the production of each pipe is standard, we come to the specific understanding of. First, the purpose and characteristics of the plug pipe The material of the plug pipe is carbon steel, stainless steel, etc. many of the pipe fittings for oil, natural, construction and many other industries, it does not need to pipe billet raw materials, production is simple, the process is also very good operation, can save the cost of pipe equipment, and the cost of the mold, it is only in accordance with the provisions of the project to repair.

Third, the material and the characteristics of the plug pipe Elbow pipe fittings and other materials elbow is different, it’s inside a number of chemical substances will make elbow surface long time of not rusty, not easy to be corroded, it’s a lot of material, such as carbon steel, alloy steel and so on, the price is very cheap, the use of a large number of alloy steel elbow is used to limit. Fourth. The difference between the plug pipe and carbon steel tube The main difference is that the material is not the same, the elbow is better than the carbon steel elbow corrosion resistance, especially stainless steel elbow it is not easy to be corroded, because it is very small carbon content, mainly high chromium content. The service life of the socket elbow is very long, and the service life can be reached for several decades. plug pipe fittings are good, it can prevent the ultraviolet ray, prevent radiation, it can let the product will always be true color, has a good corrosion resistance, it can resist many chemical substances, not afraid of acid, alkali, will not rust and breeding bacteria, not afraid of electrochemical corrosion.

Carbon Steel Pipe Fittings are very common application in our daily lives, it’s a great role, can play a role in connecting link, which is widely used in construction, pipeline and other projects, the following are some of the knowledge of carbon steel pipe fittings. We take a look, a better understanding of understanding of carbon steel pipe fittings. First,  what are the types of carbon steel pipe fittings Carbon steel elbow using a wide range of its high performance, durability, is very common in our lives in a tube, it has its own unique advantages, it is generally pided into long radius bends and steel short radius bend steel, their role is not the same, anyone who benefits, they also have different pressure levels, when in use, according to its weighing to choose. Second, the characteristics of carbon steel pipe fittings It is the method of connecting the pided threaded connection and welding, as to which method to use, depending on the needs of your project, it is not free to use, and its shape is very characteristic, but are designed to accommodate the pipeline metal pipe, according to its level under pressure, can be pided into seventeen classes as it is to bear the weight classes and its use of materials related. Third, carbon steel pipe wear Carbon Steel Pipe Fittings are generally used to wear resistant ceramic, with the development of technology, it is more and more advanced material wear, and now large international companies are using the tube to wear alumina ceramic, carbon Wear pipe fittings is a factor of the relationship between heavy security, its wear timber constantly replaced, getting better and better, the role of industrial carbon in life more important, its use in the life of the inpidual industries, such as steel, machinery and so on. Fourth, carbon steel pipe fittings processing Carbon Steel Pipe Fittings, humans have recognized, widely used in construction, decoration, and pipe fittings, it is the protection of the pipeline flow, its composition is very simple, carbon steel elbow usually done preservative treatment in the course of processing, to pressure, to make carbon steel elbow shape change, you can use cold or hot working, there must be applicable complete processing equipment, Fifth, the use of carbon steel pipe fittings It is connected to the tube link, so that the pipe has a certain turn, can better meet the needs of human life, its classification can be pided according to the material, depending on the production method of points, based on the manufacturing standards without points, but also It can be pided according to the radius, and so on. wilsonpipeline Pipe Industry Co., Limited (www.wilsonpipeline.com)

For the friend that come in contact with the insulation flange, they is have a certain understanding for insulating flange. Insulation flange in industry, petroleum, chemical industry application is very extensive, it greatly promotes the development of the gas pipeline project. A, high voltage insulation flange connection steel gate valve product structure characteristics, 1, steel gate is the wedge flexible disc structure, diameter falls within the scope of large caliber, is rolling bearing, friction small, on or off are more convenient. 2, because it is after quenching and tempering treatment, high pressure flange valve stem has a very good corrosion resistance and friction resistance. 3, can be designed into different standard pipe flange, and can meet the requirements of different users. 4, because the steel gate valve is produced by the use of special materials, therefore has the very good wear resistance, at the same time, also more resistant to high temperature, corrosion resistant, with a long life. Second, the insulation flange installation should pay attention to what matters, 1, at the time of installation, insulation flange shall be installed within the 50 m, are not allowed to install where there are welding die. 2, if the insulation flange is to be installed within the 200 m, in the case of the pipeline have died mouth, to ensure the welding of die temperature within the local average temperature, such ability can guarantee the insulation flange work better. After three, and the pipeline connection within 5 meters can’t set hanging pipeline, otherwise may cause damage to insulated flange. 4, if you want to use insulation flange measuring gas pipeline, to ensure its not to install in low areas of buried pipelines. 5, in order to guarantee the insulation flange for our better service, extend the service life of it, to ensure that the rise and fall of insulating flange pressure speed keep within 0.5 MPa. After 6, insulating flange and pipeline connection, should be timely for the pipeline repaired mouth for anti-corrosion treatment, anti-corrosion treatment, the surface of the insulation flange temperature is not higher than 100 ℃. About the structure and installation considerations to introduce how much. In a word, in order to make insulation flange can help us better, both in the installation and use of time should be done well note, this is the premise of guarantee the quality of insulating flange.

Pipeline connecting the two pipes, pipe fittings and so on in the first place. some pipes have tube plate, also belongs to the category of pipe connection, socket pipe fitting material is very good, its precision is very high, so when the connection is still very good operation. First, the characteristics of the socket bend Its weight is very light, because its density is small, so the transportation cost is very low, and easy to install, it is very health no poison, its constituent materials are environmental protection, without any toxic substance, add it to the health of environmental protection performance is certified, it has a good high temperature resistance, even if the high temperature will not melt, its impact resistance is very high. Second, socket pipe fitting standards and maintenance methods Bearing pipe can be used in the production of different materials, different specifications and types of pipe are different using occasions, want to use the appropriate combined with the characteristics of it, long stored socket pipe fitting pieces to regularly check, it exposed for a long time in the outside part often should clean, get rid of some dirt, and then put them in a spacious room ventilation, do not heap together, not in open air, in the dry and ventilated place, must be in accordance with the requirements to the store. Third, before the installation requirements Before installing, be sure to see accurate bearing pipe standards, and see if it is installed correctly, at the time of transport have any wear and tear, prior to installation to eliminate some dirt, to be prepared for all prior to installation, some of the details, guarantee the quality of installation. Fourth, socket pipe fitting valves Bearing pipe valves can only do full open or full close, not can be used to regulate traffic, lest sealing surface is damaged, to prevent leakage of filler, socket pipe fitting of different quality and standard will be used in different projects, have their own value. socket pipe fitting installation, can be directly installed on the pipe above them, is very simple, is also very good, do not need specialized technical personnel, as long as a little after training can, according to its structure to install, can be installed in the pipe of any position, more convenient operation and maintenance, it’s elbow when installation should pay attention to closure, to avoid leakage, affect the use of the pipeline.

Our exporters stainless steel flange when the Australian importer orchid trading practices, there are a lot of vendors will face rebuffed the situation, the main reason is not know enough about conditions in Australia, the principle way of doing things to take Other countries are not the same, the results for our Australian market opened stainless steel flange there will always be some difficulties here on outlet stainless steel flange to be introduced to Australia’s national problems that need attention: First thing to do is be sure to contact a good right purchasing agent. This is achieved as soon as possible and the best way to contact the Australian importer as soon as possible. Because excessive Australia within, importers has never been a direct contact with exporters, their way of doing things is through the purchasing agent to handle the import business. This approach is an Australian businessman to improve the efficiency aspect, this one is to reduce the phenomenon of cheated, then there is a problem with the existence of the party will be a better solution. Therefore, the outlet stainless steel flange to the Australian National, only to find a good agency, under the guidance of agents, will get the opportunity to meet with importers consultations. Secondly, how do get the chance to maximize collaboration with the Australian importer, in fact, very simple, that is, after the meeting to provide the most favorable price to the importer. Because the Australian tradition is not to discuss the establishment of bargaining on the price only after they consider reasonable, will move to the next link. Finally, in terms of price after the Australian importer approved, they will walk into to view sample and view retail packaging sectors. Also included in the issue has a minimum order quantity is the number, scope and quality control arrangements for shipments how. There are more than can be seen in the case of Australia’s purchase business and other purchase business substantially and there is not much difference, but in the process a little bit different. Presented here is a little different from the Australian importer of imported products once look after, they may do not examine the process of production and export stainless steel flange on signing good order. At present, China’s production is not very optimistic about the stainless steel flange, the main reason is that relatively few large-scale manufacturer of stainless steel flanges, and in many small stainless steel flange manufacturer, there are the production technology is relatively backward situation, then there is the factory scattered, to the development of enterprises, only a lot of outlet stainless steel flange, the international market. wilsonpipeline Pipe Industry Co., Limited (www.wilsonpipeline.com) is a major manufacturer of stainless steel flanges.

Threaded pipe fitting as the name suggests is a kind of with threaded pipe fitting, it is often used in all kinds of pipes, such as gas pipe, water pipe, compressed air pipe and steam pipe, etc, to reinforce the pipeline, in the process of transfer material to ensure safe and guaranteed. In industry, it is a kind of commonly used components, plays an essential role in the development of the industry. Below, we approached industrial mechanical components of the world together, to know the basic common sense about the threaded pipe fitting. The main composition, threaded pipe fitting Threaded pipe fitting is not simple to don’t need other components can be independent existence, it is also made up by a lot of smaller components, these small components including tooth tube inside and outside the tooth tube, live socket, elbow and reducer, etc., including tee, four-way pipe elbow. Second, threaded pipe fitting manufacturing standards Threaded pipe fitting is played a big role in the industry, demand so it’s very fine, can’t with other industrial components as coarse, it will affect its use and role play. From a professional point of view, threaded pipe fitting production standard is to meet GB/T 14383, ASME B16.11, BS 3799, MSS SP 83 threaded pipe fitting. Only in accordance with the threaded pipe fitting production standards can production and processing of threaded pipe fitting with good quality, also can better play its role. Therefore, at the time of production, must be in strict accordance with the threaded pipe fitting production standards for production. Three, threaded pipe fitting production materials Threaded pipe fitting is a widely used in industrial and construction components, in order to adapt to different industries, satisfy different use, threaded pipe fitting are made of different materials of material, the different kinds of threaded pipe fitting. A threaded pipe material has many different materials, we know the following important, such as cast steel, cast iron, stainless steel, plastic, rubber, graphite and thread the PVC, PPR pipe fittings. Through the above introduction and we in the life of the past experience and has formed the awareness of the threaded pipe fitting, we must now has a new understanding and the understanding to the threaded pipe fitting, also can better grasp the threaded pipe fitting. After that, we can carefully introduced threaded pipe fitting related knowledge to their friends.
