High Pressure Butt Welding With Neck Flange 4" 900# WNRF A182 F11 ASME B16.5

Butt welding flange is a kind of pipe fittings, which refers to the flange with neck and transition of round pipe and butt welding with the pipe.

Scope of application: Butt welding flanges are not easy to deform, have good sealing, and are widely used. They have corresponding rigidity and elasticity requirements and reasonable butt welding thinning transition. The distance between the welding port and the joint surface is large, and the joint surface is protected from welding temperature deformation. The relatively complex horn-shaped body structure is suitable for pipelines with large fluctuations in pressure or temperature or high temperature, high pressure and low temperature pipelines. It is generally used for the connection of pipelines and valves with a PN greater than 2.5MPa; it is also used for expensive and flammable transportation. , On the pipeline of explosive medium.
