ASTM A336 Flanges

ASTM A336 Flanges

We are leading ASTM A336 F6 Blind Flange Manufacturer in India, Check Price list and Dimensions of ASME SA336 F22 Class 3 Flange

The ASTM A336 grade covers standard specifications for pressure vessel grades. An ASTM A336 Flanges are designed in different grades, each having its own classes. The grades encompass a superior chemical composition, having enhanced strength and outstanding mechanical properties in different environments. The ASTM A336 Grade F6 Slip On Flange is the most common flange type in this range. These flanges are directly slid on the pipe fixture and welded in place, making use of one or more fillet welds. The cost-effective flanges are generally seen in low-pressure and temperature applications. The high-strength ASTM A336 F12 Weld Neck Flange is designed with a long tapered hub or a neck. These flanges are common in applications where there is tremendous stress on the fixture due to the vigorous movement of media. They are generally welded in place using a butt-weld procedure. An ASTM A336 F6 Blind Flange doesn’t possess any face type and is used in terminating the flow of fluids and gases in the hydraulic system. These flanges are bolted in place, allowing room for repair and inspection.

The SA 336 Gr F22v Lap Joint Flange is designed to work at extreme temperatures and is heat-treated between 1245 to 1688 degrees C. This flange is made up of a stub end and a ring-type sealing to close the module to the piping fixture. A lap joint flange comes in limited contact with corrosive affluents passed through it, thereby increasing its service life. ASTM A336 F91 Socket Weld Flange is seen in small pipes of high pressures. The flange is inserted in a socket and is welded in place, making use of a single fillet weld. The versatile ASTM A336 F22 Class 3 Forged Flange is produced as metal is heated at extreme temperatures to precisely shape it in the correct dimensions.
