Manufacturing process — Forged blanks, machined and drilled to standard facing

Forged blanks, machined and drilled to standard facing

  1. Ring-rolled or closed-die forged blanks for weld neck, blind and socket-weld flanges
  2. Solution annealing / heat treatment per material class
  3. CNC turning and boring to ASME B16.5 / B16.47 dimensions and facing finishes (RF, FF, RTJ)
  4. Drilling of bolt holes with orientation control; hub and bore gauging
  5. PMI on every piece; UT for critical class; hardness verification
  6. Marking (heat, size, class, grade) and EN 10204 3.1 documentation

Every stage is heat-number traceable; furnace charts, NDT records and test data are retained and issued with the mill certificate.
