Stainless Steel 321 Pipe Fittings

Pipe fittings are used in a system to join multiple pieces of pipes, tubes, and other equipment to regulate the flow of media. The Stainless Steel 321 Pipe fittings are titanium stabilized austenitic alloys that possess good content of nickel and chromium. These fittings have a density of 7.920 /cm3 and have excellent tolerance to different corrosive media across harsh conditions. They are available in seamless and welded specifications. The 321 Stainless Steel Seamless Fittings are produced as a hot billet is pushed over steel to shape the material in different sizes. These fittings possess superior strength as they don’t have any seam allowing them to be seen in high-pressure applications. SS 321 Welded Fittings possess a seam that makes them cheaper than seamless fittings. These fittings are very reliable but may not be preferred in extreme conditions.

The ASTM A403 WP321 Elbow is employed to change the direction of flow commonly in 45, 90, 22.5, and 180 degrees. These elbows are available possessing a radius of curvature of long or short specifications. A Stainless Steel 321 Equal Tee is shaped in the form of a T. These tees possess one inlet with two outlets that are arranged at 90 degrees connecting it to the main line. The AISI 321 Reducer is a versatile grade that allows it to connect piping grades of dissimilar sizes. These reducers allow for the smooth flow of media and are available in concentric and eccentric types. UNS S32100 End Cap is a fitting whose primary function is to cut the flow of media. Most of these caps possess threads that allow for easy installation in the system. The 321 SS Stub End is a short piece that has one flared end on the outside with the other end welded to the bore of the pipe. These ends can be used as an alternative to a flanged connection.
