Carbon Steel Forged Flange：
Forged flanges are used as a connection component for pipes, valves, pumps and other equipment to form a pipework system. They provide easy access for cleaning, inspection, modification or repairs. Flanges are usually welded onto pipes or screwed onto a threaded pipe end and then joined with bolts to make the connection.
