SS FLANGE DIN2573 ASTM A182 316L SOFF / SORF Stainless Steel Flange



Stainless steel weld neck flanges are mainly use to reduce the curve to smaller from a larger size of pipe, which results in greater than before pressure of the run. It has great resistant, it offer good oxidation resistant which has high temperature.


316L SS blind flanges have excellent resistance to the various corrosive media that are available in various design. These fittings are manufacture in India.


UNS S31603 SS lap joint Flanges is meant to join a pipe into a recessed area of values, fittings and flanges, Full couplings is usually to joint pipe. It can be joint by welding. They are available in several of sizes, thickness, and pressure ratings according to customers’ requirements. UNS S31603 SS lap joint Flanges are used to connect small bore pipes as a projection of a wedding effect on the pipes.


Stainless steel grade 316l flanges are resistant to carbide precipitation, they are immune to many corrosive fluids under a range of temperatures, they are used to affix pipes transporting chemical and corrosive media.
