Product Details

According to customer requirements, it can be made of 45#, 40Cr, 30CrMo, 35CrMo, 42CrMo, 18CrNiMo7-6 and other materials. According to different weights, it can be forged on different forging equipment units. The weight of forged products can reach 6kg-500kg, Forging needs to be completed through heating, pre-forging, forming, trimming and other processes.

Stainless Steel Flanges

Flange is also called flange plate or flange. Flanges are the parts that connect pipes to each other and are connected to pipe ends. There are holes on the flange, and the bolts make the two flanges tightly connected. The flanges are sealed with gaskets. Flanges are threaded (threaded) and welded.

Main role
