Product Summary

Weld neck is a flange type that shown has a minimum wall thickness of .200 inches, which in some cases exceeds API requirements. It has a long neck, and adopts welded rigid better, so how to choose the place for pressure higher standard flange is quite important to consider. As weld neck generally with forged or forged workmanship, so when using plate or steel manufacturing, the following requirements must be met: First, Steel should be the ultrasonic inspection, no layered defects. Second, it should be along steel rolling direction by cutting into strips, bending the butt into rings, and make the steel surface forming rings of cylinder, and shall not directly USES the steel plate with neck flange. Third, weld neck should use full penetration weld. Fourth; circle butt weld should undertake post-welding heat treatment and 100% rays or ultrasonic inspection. Weld Neck is with the wall thickness of the flange having the same dimensions of the matching pipe, the lighter the pipe is, the larger the bore, conversely, the heavier the pipe, the smaller the bore, they are normally used for high pressure, cold or hot temperature. It’s typically provided with a raised face, flat face, or RTJ facing. When a raised face is necessary for weld neck pipe flanges, the standard height is 1/16" for weld neck pipe flanges fewer than 400#.   For weld neck pipe flanges of 400# and up, the standard weld neck pipe flange raised face height is 1/4".   The weld neck is very resistant to dishing and has a very sturdy connection because it has the pipe along with the tapered hub. It’s ideal for extreme fluctuations of temperature. Also its ideal in environments where there may be a lot of bending and handling of the flanges. It’s used in situations where loading conditions are substantially constant or fluctuate between wide limits. This is probably the best welding flange available because of its high, heavy neck. It’s highly recommended wherever a sound welded joint connection i
