Question:

Why do not use the first gasket and tighten the flange bolts, and then welding flange welding method for flange welding?

Why do not use the first gasket and tighten the flange bolts, and then welding flange welding method for flange welding?

Answer:

If the flange screw dies, the deformation produced during welding will cause great internal stress, and may cause hidden trouble. It may cause the fracture of the flange joint when the pressure in the pipeline is very large. The gasket will also burn during welding.
Flanges produce large amounts of heat when they are welded, which will burn the gasket and deform easily under the influence of bolts and heat. The fear of harm in Wei Di apps
