The advantage of HAILI PVC loose flange:
1. Cost saving. When the pipe material is special and expensive, the cost of welding flanges 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 to prevent the flange bolt holes of the equipment from changing in the future.
