In the production of rolling weld neck flange

  In the production of rolling weld neck flange, first cut the middle plate into the appropriate sliver, the length of the sliver according to the custom design of the ANSI B16.25 Stainless Steel Weld Neck Forged Flange to set the calculation, the next is the use of butt welding flange machine The coil made into a circle, the interface using the electrode welding.

  Once again, press the flange of the weld neck flange, and through the lathe for processing waterline, chamfering and so on the process, and finally with the indexing plate with the drilling machine for bolt hole drilling processing. Weld neck flange rather than the use of forging not only because of the low cost and more important is that some of the welding flange because the caliber of the problem is not forging out, like the welding flange in the actual use is very difficult The weight of weighing, so we calculate the weight of the butt welding flange when the calculation formula is used to calculate. In the calculation has been the waterline, stop, bolt holes, chamfer weight lost.
