Process

  • Book Review: The coil forming all the pressure level
  • Welding: welding together the forming of sheet
  • Delivery: Delivery to the sheet forming machine
  • Forming: Tube Forming
  • Ultrasonic testing: the forming of the pipe by ultrasonic testing, will pick up the defective pipe
  • Cutting: The different lengths of pipe cut to length
  • Flat: tube ends debarring to smooth pipe end
  • Pressure test: The forming of the pipe by water pressure test, pressure test tube capacity
  • X-ray: tube weld test whether the tight
  • The ultimate test: Check whether the defective pipe surface
  • Standard spray: spray tube identification, production standards, specifications
  • Warehousing: storage weigh
