Welding Neck Flanges Is Suitable To The Petrochemical Field Of Flammable And Explosive High-pressure Pipelines

The Welding Neck Flanges produced by Haokun Company is suitable for the petrochemical industry of flammable and explosive high-pressure pipelines, When purchasing Welding Neck Flanges, the customer saw the neck welding flange on the purchase order, actually the neck welding welding flange is also called the high neck flange, Welding Neck Flanges is a common flange for the petrochemical high-pressure pipe network, WELDING NECK FLANGES has the corresponding rigidity and elasticity requirements and reasonable butt welding thinning transition, Large distance from the joint surface, Free from welding temperature deformation, The more complex body structure adopted by Welding Neck Flanges , Welding Neck Flanges is suitable for pipelines with greatly fluctuating pressure or temperature or pipelines at high, high and low temperature, Welding Neck Flanges is generally used for connecting pipes and valves with PN greater than 2.5MPa; Welding Neck Flanges is also used to transport tubes that are expensive, flammable and explosive medium. The Welding Neck Flanges produced by Haokun Company is generally made of forgings or forging process.When using steel plate or type steel manufacturing, our factory technical workers should be Welding Neck Flanges through ultrasonic flaw detection.No layered defects; the technical workers shall process the Welding Neck Flanges product, weld it into a ring and shape the surface of the steel.Steel plates shall not be directly fabricated into neck butt flanges; butt welds of rings shall be fully fused; butt welds of rings shall be post-weld heat treatment with 100% ray or ultrasonic detection which meet the Class II and Class I requirements of JB4730.
in the supply of flammable and explosive high pressure pipeline petrochemical industry easy Welding Neck Flanges goods must do a good job of factory detection, chemical composition detection report, especially to have heat treatment report。
