Stainless Steel Flanges is a forged or cast ring of steel designed to attach sections of pipe or join pipe to a pressure Vessel, pump or the other integral flanges assembly. Flanges are joined to every other by bolting and joined to the piping system by welding or threading. SS Flanges have only moderate resistance to carbon absorption and aren’t suggested for its usage in highly carburizing atmospheres. When frequent thermal cycling is involved, these SS slip on Flanges (often called SS SO Flanges) is immune to about 1850 Degree F. The high chromium and comparatively low nickel content of our stainless steel Threaded Flanges provide good resistance to heat sulfur bearing atmospheres.
