ASTM A182 F321 Stainless Steel Flanges and 321H Weld Neck Flange

Check Dimension of ASTM A182 F321H Blind Flange, Manufacturer of SS Werkstoff No 1.4541 Flange

Stainless Steel 321 / 321H Flanges are made up of a titanium stabilized chromium nickel austenitic stainless steel that is resistant to intergranular corrosion. The added titanium makes the material strong and safe against intergranular corrosion at temperature ranging from 425 degrees to 850 degrees Celsius. The operating temperature for these flanges can range up to 700 degrees Celsius. The Class 150 ANSI 321/321H Flanges are some of the low pressure class flanges. There are classes ranging from 150 to 2500 and from PN6 to PN64. These classes together with schedules and standards determine the pressure containment capacities of the flanges. The flanges can differ in type such as the SS UNS S32100 Orifice Flange and they can range in nominal bore sizes from ½ inches to 48 inches. The standard for this sizes scale is the B16.5. The ANSI B16.5 SS 321 Blind Flange is a special type of flange because it closes a connection unlike creating a connection with another pipe.

There are Stainless Steel 321 Slip-On Flanges which are used to fit two pipes together while allowing the pipes to slip through so that the connection location could be aligned precisely. Flanges can also be fitted with threads as in the case of ASTM A182 F 321 Threaded Flanges. These are fitted with threaded pipes. They could also be welded depending on the nature of the pipe line and the requirements of the application. The flanges are stronger with 515MPa minimum tensile strength and 205MPa minimum yield strength. The SS Werkstoff No 1.4541 Socket Weld Flanges add to the strength by having a socket that keeps the pipes in place while welding. The Stainless Steel 321 RTJ Flange makes a ring type joint which has two rings that are welded to the pipes and act a pair and allow for much surface to work on. We also manufacture and supply the SS 321 / 321H Weld Neck Flange types. Please contact us to know more.
