Product Details

The purpose of using butt welding ring loose flange is to save materials. The flange plate is made of low-grade material, and the pipe part is made of the same material as the pipe, so as to save material.

Butt weld ring 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.

Why you choose us?

Each flange undergoes a high forging process of 1000 degrees to ensure the toughness of the flange.
