Features:
Welding flange has flat welding, butt welding, and socket welding three types. A flat welding flange is suitable for low and medium-pressure pipelines. Butt welding is fine with medium and high-pressure pipelines. Socket welding flange is suitable for pressure from 1mpa to 10mpa.
This product is flat welding flange, and it is suitable for low and medium pressure pipelines.
Installation:
1. The center of pipes should be the same as the center of flanges, and the pipes should be perpendicular to the connection surface of the flanges. What's more, the position of the round holes should correspond to the same.
2. It would be easy to exchange the tubes if use the same seals in the pipes that has same pressure.
3. The connection surface of the flanges should keep clean and smooth without burrs. The nut which is used to connect should be complete without any defects, and the fitting should be natural. Then the seals should be flexible and without damage or scratches. Before connecting the flanges, we should clean the flanges first.
4.The flange installation position on the branch pipe should be more than 100 mm from the outer wall of the riser, and the distance from the wall of the building should be 200 mm or more. And the nuts should be installed in the same direction.
Whats' more, don't put the flange underground, or you should do anti-corrosion treatment.
