Carbon steel flanged fittings Butt welding flange
Description
Butt welding flange is the level of production and its technical requirements should meet the corresponding requirements of jb4726-4728. Carbon steel and austenitic stainless steel forgings with nominal pressure PN of 0.25mp-1.0mpa are selected as grade I forgings in production. Forgings with nominal pressure PN of 1.6mpa-6.3mpa shall meet the requirements of grade II or above.
Butt welding flange is generally made of forging or forging process. When steel plate or section steel is selected for production, ultrasonic flaw detection shall be carried out after production without lamination defect; steel plate shall not be directly machined into neck butt welding flange; technical parameters shall be strictly controlled during production and welding.

Characteristic
Butt welding flange is a kind of pipe fittings, which is not easy to deform, well sealed and widely used. The gap between the welded joint and the joint surface is large, and the joint surface is free from welding temperature deformation. It is suitable for pipelines with large fluctuation of pressure or temperature or pipelines with high temperature, high pressure and low temperature. It is generally used for the connection of pipelines and valves with PN greater than 2.5MPa. It is also used for the transportation of expensive, flammable and explosive media.
