Advanced Manufacturing Process
Our hot rolled seamless steel pipes are produced using industry-leading cross-roll piercing technology:
Billet Selection: High-quality certified carbon/alloy steel solid billets.
Rotary Furnace Heating: Uniform heating to optimum forging temperature.
Mannesmann Piercing: Transforming solid billets into hollow shells via cross-roll piercing.
Elongation & Hot Rolling: Reducing wall thickness and expanding length.
Sizing & Reducing: Achieving exact outer diameter and wall thickness specifications.
Heat Treatment: Normalizing, annealing, or tempering (when technically required).
Straightening & Sizing: Ensuring precise straightness per meter.
Non-Destructive Testing: 100% Ultrasonic (UT) / Radiographic (RT) inspection.
Hydrostatic Testing: Verifying pressure containment capabilities under standard-defined PSI.
Finishing, Marking & Packaging: Hard stamping heat numbers, coating, and export-ready bundling.
