Black steel pipes are produced through a system of high-rise welding machines, internal and external welding seam planers, and an ultrasonic defect inspection system; then, the pressure is tested using a hydrostatic pressure machine to check the weld quality.

The process of dipping zinc steel pipes consists of six main phases:

  • Phase 1: Clean product
  • Phase 2: Remove rust
  • Phase 3: Embed flux
  • Phase 4: Galvanize
  • Phase 5: Cool and apply surface protectant
