I. loose flange of flat welding ring:
1. Cost saving. When the pipe material is special and the price is expensive, the cost of welding the same material flange is high.
2. It is not convenient for welding or processing or requires high strength. Such as plastic pipe, glass pipe and so on.
3. It is convenient for construction. For example, it is not easy to align the flange bolt holes during connection or to prevent the bolt holes of the equipment flange from changing in the future.
II. Disadvantages of loose flange with flat welding ring:
1. Low pressure.
2. The strength at the welding ring is low (especially when the thickness is less than 3mm)
