Disk / Flange Forging Component

The basic process used for disk forging is upsetting, and then chamfering, rounding, and leveling as the subsequent auxiliary processes and finishing processes.

The flange is a part that connects the pipe to the valve or other pipes. It is to continuously beat raw material after cutting, so that to eliminate defects such as segregation and looseness in the steel ingot. The price and mechanical properties are both higher than that of ordinary cast flanges.
