EN Welding Neck Flanges manufacturer Convex welding flange is a kind of pipe fitting, which refers to the flange with neck and transition of round pipe and butt welding with the pipe. The convex face of the welding flange is not easy to deform, has a good seal, and is widely used. It has corresponding rigidity and elasticity requirements and a reasonable butt welding thinning transition. The welding port is far away from the joint surface, and the joint surface is protected from welding temperature deformation. Product Properties The butt welding flange is not easy to deform, has good sealing, and is widely used. It has corresponding rigidity and elasticity requirements and a 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 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, flammable, and explosive transportation. On the pipeline of the medium. Application Convex welded flanges have good overall performance and are widely used in machinery, chemical, construction, water supply, drainage, petroleum, light and heavy industries, refrigeration, sanitation, plumbing, fire fighting, electric power, aerospace, shipbuilding and other projects.
