Flat welding flange features:
The flat welded flange not only saves space, but also reduces weight, but more importantly ensures that the joint is not leaked and has good sealing properties. The reduced size of the compact flange is due to the reduced diameter of the seal which will reduce the cross section of the sealing face. Second, the flange washer replaces the seal ring to ensure a sealed seal. In this way, the pressure required to press the cover is reduced. As the required pressure is reduced, the size and required number of bolts can be correspondingly reduced, so the flat welded flange is small in size and light in weight. Therefore, the flat welded flange type is a relatively high quality product flange.
