OVERVIEW

Stainless Steel Flanges

TUBA offer Stainless Steel Buttweld Stainless Steel Flanges according to ASME, EN, ISO and DIN standards.Stainless Steel Pipe Flange is available in numerous grades and their mechanical properties vary widely. These Ss Pipe Flanges are used in acid and fertilizer production plants due to their corrosion resistance.

Stainless Steel Flanges is a forged, or it is called as a cast ring which is designed to connect different sections of the pipe or any other machinery that requires an intermediate connecting point. The ASTM A182 F304 Flanges could be cleaned easily with a mild detergent. Despite undergoing repeated cleaning processes, these flanges won’t wear away, an ability it exhibits due it its good wear resistance properties.

We own a highly experienced quality control expert team that performs several tests on SS Flanges to check different characteristics and parameters. The mechanical properties which are covered by the specification include tensile strength, yield strength as well as elongation and Brinell hardness values of the Stainless Steel 304 Flanges. Flanges can be stored for the longer duration in our warehouse, and from here urgent demands of industries across the globe can be completed.
