Introduction of flat welding ring loose flange

The flat welding ring loose flange is a movable flange piece, which is generally matched with the water supply and drainage fittings (the most common on the expansion joint). The pipelines and equipment are connected by bolts. The purpose of using flat welding ring loose flanges is generally to save materials. Its structure is divided into two parts. One end of the pipe is connected to the pipe, the other is made of flanging, and the flange part is sleeved on the flanging. The flange is made of low-grade materials, and the pipe part uses the same material as the pipe to save material.

Loose flange with flat welding ring:

1. Cost saving. When the pipe material is special and expensive, the cost of welding the flange of the same material is high.

2. It is inconvenient for welding or processing or requires high strength. Such as plastic pipes, glass steel pipes and the like.

3. Easy to construct. For example, it is not easy to align the flange bolt holes during connection, or prevent the flange bolt holes of the equipment from being changed in the future.
