Flange Factory is the production of flange manufacturing enterprises, the flange is the pipe and pipe connection between the parts, for the connection between the pipe end, also useful in the equipment import and export flange, for the connection between the two devices. Flange factory production process is mainly divided into forging, casting, cutting, roll system of these four kinds.
Forging technology of flange factory
Forging process is generally composed of the following processes, namely the selection of high-quality billet blanking, heating, forming, and cooling after forging. Forging process methods are forged, die forging and membrane forging. Production, according to the size of the forging quality, the number of production batch selection of different forging methods.
Foundry Technology of Flange factory
The advantages of castings are that they can produce more complex shapes with lower cost. Cast out flange, blank shape size is accurate, the processing quantity is small, the cost is low, but has the casting flaw (the blowhole.) The internal organization of the castings is poor (if it is a cutting piece, the streamline is worse);
Cutting process of flange factory
In the plate directly cut out the flange of the processing volume of internal and external diameter and thickness of the disc, and then the bolt hole and waterline processing. The flange, which is produced in this way, is called a cutting method flange, the maximum diameter of which is limited to the width of the plate.
Rolling process of Flange factory
The process of cutting a sliver with a plate and rolling it into a circle is called a roll, which is used for the production of some large flanges. After the successful roll welding, and then flatten, and then the waterline and bolt hole processing process.
