ASTM A182 Stainless Steel 304 Flanges

Check dimensions of ASTM A182 F304 SORF Flange, Manufacturer of SS 304 Flanges and SS 304 Weld Neck Flange

Stainless Steel 304 Flanges are components that are used to connect pipes together. They differ from the fittings in that all flanges have an outward projection from them that provides additional space for attachment such as welding or bolting. Roopam Steel is a manufacturer and leading supplier of these flanges. There are different standards such as the 150# ANSI SS 304 Flanges to denote the capacities of the flanges. All of these are high temperature capable up to 889 Degrees Celsius. The SS 304 Flanges is a special type with an orifice and the ANSI B16.5 SS 304 Blind Flange is another special type that it does not connect lines, but terminate a line.

There are Stainless Steel 304 Slip On Flanges which allow the pipe to slip onto them for better positioning of the connection. Sometimes, welding might not be an option. For instances like this, the ASTM A182 SS F304 Threaded Flanges are used. The ASTM A182 is a specification for forged and rolled alloy steel flanges. We are largest SS 304 flanges manufacturer in India. These are meant for high temperature services. The SS Werkstoff No 1.4301 Socket Weld Flanges have sockets welded onto them for more attachment and the Stainless Steel 304 RTJ Flange has a ring type joint that eases the connection. We also supply SS 304 Weld Neck Flange types. Please contact us for more flange information and inquiries.
