Detailed explanation of the production process of forged flanges
Main processing techniques
Raw materials entering the factory → material re inspection → cutting → heating → forging → removal of residual materials → machining → heat treatment → precision machining → surface treatment → finished product inspection → identification and protection → storage in the warehouse
(Note: For stainless steel processing → acid pickling and passivation process)
