Product introduction
Flat welding flange refers to a flange connected with vessels or pipes by fillet weld. There are two types of flange ring: with neck and without neck. Compared with the neck butt welding flange, the flat welding flange has simple structure and low material consumption. The flat welding flange is widely used for the connection of medium and low pressure vessels and pipelines.
Characteristic
1. The 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 reason why the size of the compact flange is reduced is that the diameter of the seal is reduced, which will reduce the section of the sealing surface.
2. The flange gasket has been replaced by the sealing ring to ensure that the sealing face matches the sealing face. In this way, only a small pressure is required to compress the sealing surface.
3. Flat welding flange is a relatively high-quality flange product, which reduces the quality and space and plays an important role in industrial use.
