Stainless Steel 316 Flanges

ASTM A182 F316 Blind flange and Weld Neck Flanges Manufacturer in India

Stainless Steel 316 Flanges

316 Stainless Steel Flange Dimensions differ from standard to standard. There are standards to cover short radius pipes and fittings as well as long radius pipes and fittings. There are different shapes and types of flanges. All flanges are made in a way to be connected with pipes and fittings with welding or by the tightening of bolts and nuts. There are differences in the number of bolt holes depending on the standards.

We are a well-known SS 316 Flanges Manufacturer in India. The blind flanges are used to terminate a pipeline. Most of the times, a blind flange is used to permanently close a connection. Great Steel & Metals also produces Werkstoff No 1.4401 Stainless Steel Pipe Flanges in other shapes. The 316 material is more corrosion resistive and stronger than the ordinary 304 stainless steel. Therefore the flanges made out of this material are also stronger. The high chromium and nickel content in the ASTM A182 F316 Slip On Flange makes them stronger and long lasting in a piping system. The pressure containment capacities of the threaded flanges are covered by 316 SS Threaded Flange Pressure Ratings. The flanges manufactured by us are high quality and are according to the ratings and standards. The UNS S31600 SS316 Sorf Flange is used mostly in plumping applications. The others include the ASTM A182 Grade F316 Weld Neck Flanges which are used in food processing, brewing and mining industries. We produce 316 flanges in different capacities to suit our customer needs across marine, automotive, aerospace, medical and oil and gas applications
