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.
