Flange factory is a production enterprise producing flanges. Flanges are parts connected between pipes, which are used for the connection between pipe ends. It is also useful for the flange on the inlet and outlet of the equipment for the connection between two devices. The production technology of flange factory is mainly divided into forging, casting, cutting and rolling.

Forging technology of flange factory

Forging process is generally composed of the following procedures, that is, select high quality billet blanking, heating, forming, after forging cooling. Forging techniques include free forging, die forging and foetal forging. Production, according to the size of the forging quality, the number of production batch choose different forging methods.

Foundry technology of flange factory

The advantage of castings is that they can be produced in a more complex shape at a lower cost. Cast out of the flange, blank shape and size is accurate, small processing, low cost, but there are casting defects (pores. Crack. Inclusion); Poor streamlining of the internal structure of the casting (even worse in the case of cutting parts);

Flange factory cutting technology

The disc with the inner and outer diameter and thickness of the flange is directly cut out on the middle plate, and then the bolt hole and waterline are processed. The flanges produced in this way are called cut flanges whose diameter is limited to the width of the middle plate.

Flange factory rolling process

The process of cutting the slivers with the middle plate and then rolling them into a circle is called coiling, which is mostly used in the production of some large flanges. After successful coiling, it is welded, then flattened, and then processed with waterline and bolt holes.
