Flanges

Flanges, such as welding neck flanges, threaded flanges or blind flanges can be used either to connect pipelines, or to secure fittings and valves within the pipelines.

Flanges made of steel or stainless steel

Flanges can be made of steel C22.8, stainless steel 1.4541 or stainless steel 1.4571. Depending on the pressure ranges, flanges for a nominal pressure of PN10, PN16, PN25 and PN40 are available. All of our flanges are EN1092-1. The sealing surface is made according to B1 shape. The welding neck flanges are type 11, the blind flanges type 5 and our threaded flanges type 13.
