The cost of rolling the flange is lower than forging. But some of the large flange is not forging out. Such products are mostly weight with the theoretical weight, in the calculation, is not the waterline, mouth, bolt holes, chamfer weight loss. The price of flat products is lower, but if there is a process of processing the dovetail and the like, the price of the large flange will be higher. The theoretical weight is calculated by the following formula
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.
