The role of Bazi blind board:
The purpose of using butt welding ring loose flange is generally to save material. Its structure is divided into two parts, one end of the pipe is connected to the pipe, and the other end is made of a butt welding ring. The flange is made of low-grade materials, and the pipe part uses the same material as the pipe to save material.
advantage:
Cost saving, when the pipe material is special and expensive, the cost of welding flanges of the same material is high.
It is inconvenient for welding or processing or requires high strength, such as plastic pipes and glass steel pipes.
It is convenient for construction, for example, it is not easy to align the flange bolt holes during connection or prevent the flange bolt holes of the equipment from changing in the future.
Disadvantages:
Low pressure, low strength at the weld ring (especially when the thickness is less than 3mm)
