Characteristic
Flat welding flange is suitable for the pipeline system with low pressure level and no serious pressure fluctuation, vibration and vibration. The advantages of flat welding flange welding assembly is easy to center, and the price is cheaper, so it has been widely used.
Flat welding flange has sealing principle. The two sealing surfaces of the bolt squeeze the flange gasket and form a seal, but it also leads to the damage of the seal. In order to maintain the seal, it is necessary to maintain a large bolt force, for which the bolt must be made larger. Larger bolts need to match larger nuts, which means larger diameter bolts are needed to create conditions for tightening nuts.
