Manufacturing Process

  1. Billet Selection: Premium quality carbon steel billets undergo rigorous testing

  2. Heating: Billets heated to 1200-1300°C in controlled atmosphere furnaces

  3. Piercing & Rolling: Hot piercing creates the initial hollow shell, followed by rolling to achieve precise dimensions

  4. Sizing & Straightening: Precision sizing ensures dimensional accuracy, with straightening for perfect alignment

  5. Heat Treatment: Normalizing/annealing processes optimize mechanical properties

  6. Finishing: Pickling, passivation, and coating options available

  7. Testing: Comprehensive non-destructive testing including ultrasonic, eddy current, and hydrostatic testing
