Description of API 5L Seamless Steel Pipe Equipment
Oil standard: Hydraulic pressure tester prevents oil corrosion after passing through the steel pipe, and marks according to user's requirements.
Leveling Milling: The original steel plate is pressed flat by the anvil, and then the two sides of the steel plate are milled using the edge milling machine to achieve the required plate width, parallelism and groove shape.
c. Shear forming: The steel plate on the production line is crimped into a tube along the outer spiral.
Butt welding: The seamless steel pipe equipment market uses advanced double-sided submerged arc welding technology for pre-welding, welding, and external welding. The welded steel pipe is cut to a standard length with a plasma rod.
Visual inspection: Some basic parameters are checked by professional technicians.
Ultrasonic flaw detection: 100% inspection of steel scraps on both sides of internal and external welds and parent metal.
Radiographic inspection: 100% internal and external weld X-ray industrial television inspection using image processing system to ensure detection sensitivity.
Hydrostatic test: The root test is performed on the steel pipe on the hydraulic pressure tester to ensure that the steel pipe meets the required standard test pressure.
I. Chamfer flat head: The seamless steel tube equipment will be tested through the steel pipe end pipe to achieve the required pipe end (spiral welded pipe unit) groove size.
J. Final inspection: The leveler is again ultrasonic and X-ray flaw detection and magnetic particle inspection finished, check for welding problems and pipe end defects.
Exploration of the K. Uncoiler plate: After the steel plate opens into the production line, the first full plate ultrasonic flaw detection.
