SCH40 SCH80 Forged Carbon Steel Flange Standard ASME B16.5 ASTM A105 Weld Neck

Flange is a movable flange piece, which is generally matched with water supply and drainage fittings (the most common on expansion joints). When the factory leaves the factory

There is a flange at each end of the expansion joint, which is directly connected with the pipeline and equipment in the project by bolts. Use flat welding ring loose flange

The purpose of the pan is generally to save materials. Its structure is divided into two parts. One end of the pipe is connected to the pipe, and the other is made of flanging.

, The flange part is sleeved on the flange. The flange is made of low-grade materials, and the pipe part uses the same material as the pipe.
To achieve the purpose of saving materials.

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.
