Production process of flange

Our company's flange manufacturing process is divided into two kinds: Casting flange and forging flange

Forged flange is generally lower carbon content than cast flange and is not easy to rust. The forging has good streamline, compact structure and better mechanical properties than cast flange.

Forgings can bear higher shear force and tensile force than castings.

The advantages of casting are that it can produce more complex shape and lower cost.

The forging has the advantages of uniform internal structure and no harmful defects such as pores and inclusions in the casting.

The process of forging flange is generally composed of the following processes, i.e. blanking, heating, forming and cooling after forging. The forging process includes free forging, die forging and die forging. In production, different forging methods are selected according to the forging quality and production batch.

Flange is widely used in chemical engineering, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, water heating, fire protection, electric power, aerospace, shipbuilding and other basic engineering because of its good comprehensive performance.

The general processing and manufacturing procedures of flange are: purchase of raw materials → cutting and blanking → solid solution → forging and forming → lathe finishing.
