The SS Pipe Flanges range from ½ inches through 48 inches in general application services. There are different types based on the production, design and functionality of the SS Flanges. There are different use cases like the ASTM A182 which specify flanges and components for pressure vessel grade applications

The Metric Stainless Steel Pipe Flanges are of high quality and are tested according to the international standards. There are different grades of stainless steel such as the 304, 304L, 316, 316L and so in which the SS Pipe Flanges are made through. The different grades of the materials have different mechanical and physical properties along with different corrosion resistance levels. The Stainless steel weld flanges are used with welded applications as well as seamless flange. The seamless ones have less absolute roughness and are better off with instrumental applications.
