Stainless Steel Flanges

Buy Class 300 SS Blind Flanges at Factory Price, ASME B16.5 Stainless Steel Slip On Flange manufacturer in India

Stainless Steel Flanges are products used in piping systems to connect pipes together. The flanges are more advantageous than fittings because they often have a projection perpendicular to the pipe’s length. This part of the flange helps for additional grip to the attachment. Roopam Steel is a manufacturer and supplier of stainless steel flanges in all shapes, sizes and material grades. The Stainless Steel Blind Flanges differ from all other flanges in that they actually do not connect more pipes to continue the piping, they terminate a piping. A blind flange is applied when the flow has to stop completely. The Stainless Steel Plate Flange just looks like a ring that can hold the pipe inside. When two of these plate flanges are fitted at the ends of two different pipes, it becomes easy to weld or bolt the pipes together.

ASTM A182 Stainless Steel Flanges

Class 300 Stainless Steel Flanges

ANSI B16.5 Flange

Best Quality SS Weld Neck Flanges exporter in India, manufacturer of Stainless Steel Socket weld flanges in all pressure ratings

The Stainless Steel Weld Neck Flange has a welded neck on it to provide extra strength; the SS Slip on Flange allows the pipes to slip on through it so that the pipe can be adjusted for the correct location of joint. The flanges could be made up of different methods as well. The SS Forged Flanges are common as they possess more strength from the forging from one piece of metal. The SS Threaded Flanges have threads at the ends and there are different pressure classes to the flanges such as the Class 300 Stainless Steel Flanges and the Class 150 SS Pipe Flange.
