Butt welding flange

Butt welding flange is not easy to be deformed, sealed, widely used, has corresponding rigidity and elasticity requirements and reasonable butt welding thinning transition, the welding joint is away from the joint surface, the joint surface is protected from welding temperature deformation, it takes more complicated It is suitable for pipelines with high pressure or temperature fluctuations or pipelines with high temperature, high pressure and low temperature. It is generally used for the connection of pipelines and valves with PN greater than 2.5MPa. It is also used for expensive, flammable and explosive. On the tubing of the media.
