Introduction of rolling large diameter flange

Rolling flange is cut into strips with medium plate, and then rolled into circular welding joint, and then processed by flattening process. It can be divided into cold coil and hot coil. After being processed into a circle, the water line, bolt hole and mouth stop are processed. This is generally a large flange, a molding can be done 7 meters.

Forging Rolling Flange Production

Rolling flange is cut into strips with medium plate, and then rolled into circular welding joint, and then processed by flattening process. It can be divided into cold coil and hot coil. After being processed into a circle, the water line, bolt hole and mouth stop are processed. This is generally a large flange, a molding can be done 7 meters. Most of them are plate type flat welding flange, and the connection mode is welding. If the production process of segmented production is used, the specifications of 12m-15m or larger can be achieved. This kind of flange has good quality assurance.

Because the raw material is medium plate with good density. The welding process at the joint of rolled flange is the most important, and X-ray or ultrasonic inspection should be done. When the joint is finished, the material of the whole flange will be no problem. Relatively speaking, the price of the products with thin thickness, light weight, narrow one side of the product and some sealing groove processing is higher, while the price of some thick, heavy weight and no complicated processing technology is lower.
