The butt welding flange is now not effortless to deform, seals well, is broadly used, has the corresponding inflexible and elastic requirements and practical butt welding thinning transition, the welding joint is a long way from the joint surface, and the joint floor is blanketed from welding temperature deformation, it adopts a greater complicated cough flare structure, which is appropriate for pipelines with giant fluctuations in strain or temperature or pipelines with excessive temperature, excessive strain and low temperature, and is usually used for the connection of pipelines and valves with PN increased than 2.5MPa, and is additionally used for transporting expensive, flammable and explosive medium pipelines.
