The ASME/ANSI B16.9 specification covers the dimensions and the tolerances of carbon, alloy and stainless-steel butt weld fittings.

Butt Weld Fittings are manufacture by seamless or welded pipe. For pipe fittings manufacturers, the forming process of welded pipe and seamless pipe is basically same. Butt welded fittings can be divided into carbon steel butt welded fittings and stainless-steel butt-welded fittings.

An equal tee, otherwise called straight tee, means the branch diameter of this tee is same with the main pipe (Run pipe) diameter of this tee.
A pipe tee is defined “equal” when the bore size at the run and branch sides have the same diameter. An equal tee is, therefore, used to connect two pipes of the same nominal diameter.
