High pressure welding flange pipe fitting in the use of outstanding use value and effect, according to the corresponding way and method of use, avoid in the use of the quality and function problems. In the application of high pressure butt welding flange pipe fitting, there will be a corresponding reduction in the scale. The reason why the size of the high pressure butt welding flange pipe fitting decreases is that the diameter of the sealing element is reduced, which will reduce the cross section of the sealing surface. Secondly, the high pressure butt welding flange gasket has been replaced by a sealing ring to ensure that the sealing face sealing surface match.

High pressure butt welding flange fitting connection method is suitable for pipe diameter from 32-315mm pipe fitting connection. The device is a socket extension shortening pipe connector, which is fixed by anchoring pipe clamp to prevent the bearing tube from moving during hot expansion and cold contraction. On vertical pipes between floor slabs, on long distance collection pipes and buried pipes, at least one socket extension shorten pipe of equipment. Generally used in the pipeline, loose bolts can turn the two ends of the pipeline, and then tighten can be more convenient to dismantle the pipe raw material is carbon steel flange pipe fittings called large flange pipe fittings. This is because the plug shortens not only eliminate heat expansion and cold contraction due to temperature changes during drainage, but also facilitate the connection with the branch pipes on each floor, making the piping simpler.

High pressure butt welding flange pipe fittings is a kind of flange pipe fittings with outstanding technological characteristics and functions, which can show outstanding application value and effect in application, and overcome the defects of traditional high pressure butt welding flange pipe fittings. High pressure butt welding flange pipe fittings is two large diameter pipe connection equipment, usually two flange pieces plus a number of fastening bolts. High pressure butt welding flange pipe fittings is made of carbon steel flange pipe fittings. Low carbon steel has good plasticity and low strength. After adding appropriate carbon elements, it will become hard and its plasticity will reduce and strengthen.
