Usoro nrụpụta

Usoro nke imepụta Pipe Longitudinal Submerged-arc Welded(LSAW) bụ nke a:

Ultrasonic plate probing → ihu igwe → tupu ekwe → akpụ → tupu ịgbado ọkụ → Ime ịgbado ọkụ → Mpụga ịgbado ọkụ → Ultrasonic nnyocha → X-ray nnyocha → Ịbawanye → hydraulic ule →l.Chamfering → Nyocha Ultrasonic → Nyocha X-ray → nyocha ihe ndọta na njedebe tube.
