Butt welding pipe fittings

What are butt welding pipe fittings?

Butt welding pipe fittings are one of the most popular connection types in pipeline systems.Pipe fittings have the connecting end for butt welding(BW) that called butt welding pipe fittings.The butt welding pipe fittings are used to connect steel pipes or pipe fittings which have the same size and schedule butt welding ends.It is designed for changing pipe direction and pipe diameter,branching or ending a pipe system.The ends of butt welding pipe fittings are usually plain ends or bevel ends.Butt welding pipe fittings are available in sizes from ½” to 72″.
