Stainless Steel Cross

Steel pipe cross fittings are designed and manufactured according to international standard of ASME B16.9. It may have one inlet and three outlets or three inlets and one outlet. The common used material are carbon steel and stainless steel.

Buttwelding Fittings are used in a piping system to change direction or function of media, to branch off, reduce pipe size or attach auxiliary equipment. They are availbale in multiple types as elbow, tee, cap, reducer, stub end and oelt, that produced in cold and hot forming based on ASTM A403 and ASTM A234 specification.
