Description

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

Because of the transition structure and butt welding connection of the cone neck, the strength and rigidity of the flange are strengthened, and the sealing performance is better than that of the flat welding flange. The disadvantage is that it needs to be made of forgings, which consumes a lot of materials and costs a lot of manufacturing. Suitable for occasions with high pressure and temperature or high sealing requirements

Applications

Butt-welding flange is not easy to deform, sealed well, and widely used, with corresponding rigidity and elasticity requirements and reasonable butt welding thinning transition. The distance between the welded junction and the joint surface is large, and the joint surface is free from welding temperature deformation. It adopts a relatively complex trumpet shape structure, which is suitable for pipelines with large 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 in pipelines conveying expensive, flammable and explosive media.
