Carbon Welded Seamless Spiral Steel Pipe Round Metal Pipe for Pipeline Construction
What is a spiral steel pipe?
What is a spiral steel pipe spiral is a double pipe wound at room temperature, which is made by welding the pipe and using the lower wire bending steel coil bending process. Double-wire double-sided submerged arc welding process
(Making forming corners) Rolled to tube, made from welded joints, can be made into larger diameters from narrower production tubes. During the welding process, the plate is deformed evenly, the streamline is small, and the surface has no scratches. The thickness of the strip has more flexibility. The flexibility of the tube is an unparalleled advantage in manufacturing and the needs of these small sizes, especially when you need to meet the high-end thick tube.
After unwinding plate inspection, pass flat plate inspection: enter the unwinding plate production line, first perform full plate edge inspection
Milling and finishing: the flat steel cutting board is rolled to make the original, and then the milling machine performs double-sided steel milling, and the board edge inspection is performed immediately
Shearing shape: The steel plate is rolled into a tubular shape along the outer winding
Butt cutting: using advanced submerged arc welding technology for double-sided welding, internal welding and external welding
Visual inspection: Some basic parameters are checked by professional technicians. Weld
Convenient welds: 100% inspection of outer welds and base material outer welds
Detection range: X-ray inspection: 100% X-ray industrial TV processing system for external welds, ensuring the use of image inspection
Pressure Test: Thread
If the oil meter is detected: apply oil after the inspection port to prevent corrosion, and ask the user to perform a hydrostatic test, and ask the user to test. Chalking, Inspection and Welding End Tube Defects
