The use of the value and role of high-pressure welding flange
Hyperbaric welding neck flange in use has good use value and function, used in accordance with the corresponding ways and methods to avoid some problems of quality and function in use. High pressure welded flange in use will have corresponding to the size of the reduction, high pressure butt welding flange the reason why reducing the size of is due to decreasing the diameter of the seal. This will reduce the sealing surface of the section. Secondly, high pressure flange gasket sealing ring has been replaced to ensure that the sealing face of the sealing surface of the match.
High pressure flange connection method for pipe diameter connection from the diameter of 32-315mm. Install the socket type telescopic tube connector must use anchoring clip of fixed, to prevent in thermal expansion and contraction in bearing intubation position of mobile. In between the floor and floor vertical erected collection tube and long distance pipe line and the underground pipelines must be installed at least a socket type telescopic tube. Generally used in the pipeline, loosen the bolts can be rotation on both sides of the pipeline, and then screw can be more convenient to assembly and disassembly of the pipe material is carbon steel flange is called large flange. This is because the socket type telescopic tube can not only eliminate the drainage process temperature changes caused by heat expansion and cold contraction, and help with each floor pipe connection, the pipeline installation is more simple.
High pressure welded flange is a has good process characteristics and performance of flange products, can be in use show good use value and role, to overcome the shortcomings of the traditional high pressure welding neck flanges. Connecting device for high-voltage welding flange is two large diameter pipeline, usually two flanges and several fastening bolts. High pressure flange welding flange is made of carbon steel. Low carbon steel of low strength, after adding suitable amount of carbon will become hard plastic lower intensity.
