Process Flowchart of SSAW Steel Pipes
Coil probe: steel coil into the production line, the fifirst full board Ultrasonic Inspection
Leveling milling: through anvil plate leveling machine so that the original curl, and then pass the two edges of steel-sided milling machine milling, so that up to the requirements of the plate width, plate edge parallel groove shape
Cut type: steel production line along the outer edge of the coiled-coil tube
Welding and cutting: the use of advanced technology for pre double submerged arc welding cutting inside from the foot of the welding specifification welded steel pipe welded outside use, etc.
Visual inspection: some basic parameters by a professional technician check
Ultrasonic flflaw: the inner and outer sides of the base metal and weld seam 100% inspection
X-ray detection: internal and external welds 100% X-ray television industry checks, the use of image processing system ensures detection sensitivity
Pressure test: hydrostatic testing machine by-root test steel pipe up to the standard requirements to ensure that the test pressure
Chamfer level: steel pipe inspection pipe end processing, up to the requirements of the pipe end beveling size
Check: X-rays and then subjected to ultrasonic testing and magnetic particle inspection conducted pipe end, check whether the deposit welding problems and defects in the pipe ends
Oiled marking: Qualifified oiled steel pipe corrosion and in accordance with user requirements for marking
