Flange factory is the production of flange production enterprise, flange is connected between the pipe and the pipe parts, used for the connection between the pipe end; Also useful in the equipment inlet and outlet flange, for the connection between two equipment. The production process of flange factory is mainly divided into forging, casting, cutting and rolling.
Flange factory forging process
The forging process is generally composed of the following procedures, namely selecting high-quality billet feeding, heating, forming, and cooling after forging. The forging process includes free forging, die forging and membrane forging. Production, according to the size of the forging quality, the number of production batch choose different forging methods.
Flange factory casting process
The advantage of casting is that it can produce a more complex shape and the cost is relatively low. Casting flange, blank shape and size is accurate, processing amount is small, low cost, but there are casting defects (pores. Crack. Inclusion); The internal structure of the casting is less streamlined (if it is a cutting part, the streamline is worse);
Cutting technology of flange factory
The disc with the inner and outer diameter and thickness of the flange is cut out directly on the middle plate, and then the bolt hole and water line are processed. The flange produced in this way is called cut flange, this kind of flange diameter to the width of the plate is limited.
Flange factory rolling process
The process of cutting slivers from a medium plate and then winding them into a circle is called winding, which is used in the production of some large flanges. After the winding is completed, welding is performed, then flattening is performed, and the waterline and bolt holes are processed.
