Stainless steel flanges

Tested flanges made of duplex steel

By using flanges, primarily pipe sections and also air ducts are tightly connected to one another. Sealing is achieved by contact pressure of the surfaces on the seals – these are generally applied with screws. Usually, the flanges are welded to the pipe. We stock different flanges for various applications and stainless steel pipes – from welding flanges to blind flanges and smooth flanges.

Welding flanges have an attachment for welding, such as a pipe. They are preformed from a blank, annealed and finished by drilling and turning. Due to their construction, they have a particularly high stability and can also be used at high pressures. Blind flanges, on the other hand, are primarily used for the closing of nozzles on pressure tanks because they do not have a central bore. The flanges are available in various materials such as super duplex or duplex steel.

High quality stainless steel flanges with certification

All conventional approval test certificates to EN 10204 with certification to DIN/EN and/or VdTÜV material sheets or corresponding ASME are standard with our products. We can carry out short-term additional tests to individual customer specifications and also provide certification.
