Flat welding flange is applicable to the pipeline system with low pressure grade and no serious pressure fluctuation, vibration and shock. The advantage of flat welding flange is that it is easy to align when welding and assembling, and the price is relatively cheap, so it has been widely used.
Flat welding flange not only saves space and reduces weight, but also ensures that the joint will not leak and has good sealing performance. And the flange size is reduced, reducing the mass and space, which plays an important role in industrial application.
