Flat welding flange has many uses. Flange is a device connecting pipes. There are many specifications in the flange market, and the flange is divided into integral flange, looper flange and threaded flange. They are used in different places. Generally also referred to as flat plate, also known as lap welding flange. The connection between flange and pipe is to insert the pipe into the flange hole to a proper position, and then lap weld.

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.
