When stainless steel encounters a special environment, some local corrosion will occur, such as pitting corrosion, intergranular corrosion, stress corrosion, and galvanic corrosion. Therefore, all stainless steel elements have a common characteristic, that is, the chromium content is above 10.5%. In addition, if the surface layer is damaged, the exposed steel surface will react with the atmosphere, repair itself and form a "passivation film" again, which will continue to play a protective role. This oxide layer is very thin, and the natural luster of the steel surface can be seen through it. Pressing a stainless steel fitting can be completed within 5 seconds with the correct equipment. This tightly attached chromium-rich oxide protects the surface from further oxidation. The reason is that when steel is alloyed with chromium, the type of surface oxide is changed to be similar to the type formed on pure chromium metal. When the added chromium content reaches 10.5%, the atmospheric corrosion resistance of the steel is improved, and the chromium content of the 316L stainless steel welded pipe is more than 17%. The surface of 316L stainless steel welded pipe will also react with oxygen, but due to its high chromium content, the corrosion resistance of stainless steel depends on chromium. The difference is that the iron oxide formed on the surface of ordinary carbon steel will continue to oxidize, causing the corrosion to continue to expand and eventually forming holes. Into the desired shape.The surface of all metal products will react with oxygen in the atmosphere to form an oxide film on the surface. Is filling the middle of the pipe with liquid, the hydraulic will bulge pipe Servicing industries throughout the United States, Canada, Mexico, Australia, Europe, the Middle East and more, our US production facilities in both Wisconsin and Kentucky are prepared to deliver quality stainless. The pipe is bulged forming Another method is hydraulic bulging forming. Felker Brothers Corporation is proud to be a leading manufacturer of stainless steel piping products and fabricated piping systems. Bulging Manufacturing MethodĪ rubber is placed in the tube and the top with a punch compression, then Then adjust the fixed rollers spacing and the finished product is bend. Two fixed rollers and one adjusted roller. One is stretching, another is stamping, the third is roller, there are 3-4 rollers. Bending Manufacturing Methodįor making stainless steel elbow and bend fittings. Using tapered core to expand the stainless steel pipe end to the required size and shape in the punching machine. Then pushing the external by roller and processing the rim. Best Prices available for next day delivery.
Stainless steel butt weld fittings, putting the core in the stainless steel pipe. Buy Pipe Fittings in all materials online from UKs leading pipe shop and pipe fitting supplier. The common types are rotary, connecting rod and roller type. Manufacturer of Seamless/ Welded Stainless Steel 316L Pipe Fittings such as ASTM A403 WP316L Elbow, Reducer, Stub End, Tee, BW Cap according to AWWA C208, ASME B16.9, EN 10253-4, EN 10253-2 standards. Making method of stainless steel forged fittings,using forging machine bevels the stainless steel pipe end or extension, reduce the outside diameter. Trenton Pipe Ss304-60202 1/4' Class 150, 90 Degree Street Elbow, Stainless Steel 304 - Pkg Qty 25. Male threads are on the outside of a fitting and screw into the female threads. Female threads are on the inside of a fitting. Threaded pipe fittings are threaded on both connection ends. They are including butt weld, socket weld and threaded fittings. Class 3000 threaded stainless steel fittings connect with high-pressure (1000-3000 psi) pipe.
According to stainless fittings manufacturing methods, they are available in types of Elbow, Tee, Cross Tee, Reducer, Cap, Bushing, Plug, Coupling, Union and so on.Īccording to connection method.
