WN Flange is generally made by forging or forging. When using steel or steel manufacturing, must meet the following requirements:
1, the welding flange should be ultrasonic testing, no delamination defects;
2, should be cut along the direction of steel rolling into a strip, the bending system welded into a ring, and the surface of the steel ring to form the cylinder. Shall not be directly machined into steel with a neck welded flange;
3, the ring butt weld should be used full penetration weld;
4, the ring butt weld should be post-weld heat treatment, and for 100% ray or ultrasonic flaw detection
WN Flange has a higher rigidity than a flat welded flange with a neck and a high butt weld strength, which is less prone to leakage.
High-quality products
Welded neck flange not easy to distortion, good sealing, widely used, butt thinning transition weld joints ,horn shape, avoid shape change when welding in high temperature. applicable to high temperature pipeline, high pressure and low temperature pipeline, normally used to connect pipes and valves which PN is greater than 2.5MPa; also used to transport expensive, flammable, explosive media pipeline.
