ASTM A182 F321H, F11, F316L Large Diameter Stainless Steel Flanges For Chemical Industry
ASTM A182 F321H Stainless Steel Flanges are used to connect pipes, valves, pumps and other tool to form a piping system. It is usually welded or screwed. ASTM A182 F321H Stainless Steel Flanges are made by bolting two flanges together with a gasket between them to provide a seal. It is an austenitic material which can be stabilized with the addition of Titanium. F321H Stainless Steel Blind Flanges are flanges that don't have a hub or a bored center. This flange has a face thickness of a flange, a matching face type, and similar bolting pattern. It can be used to seal a nozzle opening on a pressure vessel. It has high strength, resistance to scaling, and phase stability, with resistance to subsequent aqueous corrosion.
