  The heavy Forged A105 Carbon Steel Weld Neck Flange (BW)

  The heavy Forged A105 Carbon Steel Weld Neck Flange (BW) are also named heavy WN flanges, which are hot formed from a circular section of steel plate having a very small co-axial hole in the flange center. The steel around the hole is shear-formed downward and outward by a tapered die plug which is forced by the small hole forming an integral neck on the weld neck flange. A supporting ring die is radiused at its inner corner to form a suitable fillet radius at the junction of the neck with the flange proper. A suitable pre-forming or post-forming operation may be required to compensate for any deflection in the work piece out of planar configuration.
