JIS Flanges Manufacturer in Jiangsu, China

Short Description:

The loose flange is sleeved on the pipe end by using collar , a steel ring, etc., and the loose flange can be moved on the pipe end. Steel rings or collars are the sealing faces, and the loose flanges act to compress them. It can be seen that the loose flange is not in contact with the medium due to being blocked by the steel ring or the collar. Because the flange is movable and is not directly connected to the pipe, it is called a loose flange. There is another term called a lapped flange.
