Forging production process of flange pipe fitting

2021-11-05 09:50:57

Pipeline flanges are divided into the following six basic types according to their connection with steel pipes: flat welding flanges, butt welding flanges, socket welding flanges, loose flanges, threaded flanges and integral flanges.

The production process of flange pipe fitting is mainly divided into four types: forging, casting, cutting and rolling. Forged flanges generally have lower carbon content than cast flanges and are not easy to rust. Forgings are streamlined, have a denser structure, and have better mechanical properties than cast flanges.

Improper forging process will also cause large or uneven crystal grains, hardening cracks, and forging costs higher than cast flanges. Forgings can withstand higher shear and tensile forces than castings.
