The requirements of flat welding flange forging process on equipment are stricter than that of traditional die forging, and the displacement characteristics of the punch must match the deformation densification characteristics of the preform. The contact time between the blank and the mold should be as short as possible. The forging press must have good rigidity, and the movable beam and piston must have good guiding accuracy to ensure the accuracy of the forging. Therefore, mechanical press, such as Crankshaft Press, or friction press with high precision is generally selected for flat welding flange forging.
Flat welding flange not only saves space and reduces weight, but also ensures that the joint will not leak and has good sealing performance. The compact flange size is reduced because the diameter of the seal is reduced, which will reduce the cross-section of the sealing surface. Secondly, the flange gasket has been replaced by the sealing ring to ensure that the sealing surface matches the sealing surface. With the reduction of the required pressure, the size and number of bolts can be reduced accordingly, so a new product with small volume and light weight (70% ~ 80% less than the weight of the traditional flange) is finally designed. Therefore, the flat welding flange is a relatively high-quality flange product, which reduces the quality and space and plays an important role in industrial use.
