Description:
A 3/4 Asme B16.9 Class150 Welding Neck Flange is a type of pipe and refers to a flange with a neck that has a transition of a round pipe and is butt welded to the pipe. Butt welding flange is not easy to be deformed, sealed well, widely used, has corresponding rigidity and elasticity requirements and reasonable butt welding thinning transition, the welding joint is away from the joint surface, and the joint surface is free from deformation of welding temperature.
Scope of application:
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 high temperature, high pressure and low temperature pipelines. 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 transportation pipeline.
