Butt welded flange is a kind of pipe fittings, which refers to the flange with neck and transition of pipe and butt welded with pipe. Butt-welded flange is not easy to deform, sealed well and widely used. It has corresponding rigidity and elasticity requirements and reasonable butt-welded thinning transition. The distance between the weld and the joint surface is large, and the joint surface is free from welding temperature distortion.
Butt-welding flange is not easy to deform, sealed well and widely used. It has corresponding rigidity and elasticity requirements and reasonable butt-welding thinning transition. The distance between the weld and the joint surface is large, and the joint surface is free from welding temperature distortion. It adopts a relatively complex cough horn structure. It is suitable for pipelines with large fluctuation of pressure or temperature or pipelines with high, high and low temperature. It is generally used for pipelines with PN greater than 2.5 MPa. Connection of pipes and valves; also used to transport expensive, flammable, explosive media pipelines.
