Butt welding flange complete specifications

The scope of application of the butt welding flange has corresponding rigidity and elasticity requirements, is not easy to deform, has good sealing performance, and is widely used. Reasonable butt welding thinning transition. The distance between the joint and the joint is large, and the joint has no temperature deformation after welding. With a complex bell-shaped structure, it is suitable for pipelines with large pressure or temperature fluctuations or high-temperature, high-pressure, and low-temperature pipelines. It is generally used to connect pipelines and valves with a PN greater than 2.5MPa; it is also used to transport expensive flammable and explosive materials. medium pipeline.Weld Neck Flange       Material     Carbon steel ASTM A105, A350 LF1, LF2, LF3, LF6, CL1/CL2,; A…
