Applications

Butt weld elbow is a steel elbow formed by hot pressing or forging. Its connection form is to directly weld the elbow and steel pipe. Butt welded elbows are mainly used for elbow with higher pressure and temperature than other connection types (socket welded elbow or threaded pipe elbow).

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.
