Transportable Factory Steel Pipe Spiral Welded Pipe

Spiral welded pipe: It is made by rolling low-carbon carbon structural steel or low-alloy structural steel strip into a pipe blank according to a certain spiral angle (called forming angle), and then welding the pipe seam, which can produce large-diameter steel pipes with narrower strip steel. Its specifications are expressed by the outer diameter * wall thickness, and the welded pipe should ensure that the hydraulic test, tensile strength and cold bending performance of the weld should meet the regulations.

Industrial TV internal inspection equipment: inspect the appearance quality of internal welds.
Magnetic particle flaw detector: inspect the near-surface defects of large-diameter steel pipes.
Ultrasonic Automatic Continuous Flaw Detector: Inspect the transverse and longitudinal defects of the full-length weld of the spiral steel pipe.
Ultrasonic manual flaw detector: re-inspection of large-diameter steel pipe defects, inspection of repair welds and weld quality after hydropressure.
X-ray automatic flaw detector and industrial TV imaging equipment: inspect the internal quality of the full-length weld of the spiral steel pipe, and the sensitivity is not less than 4%.
X-ray imaging equipment: inspect the original weld and repair weld, and the sensitivity is not less than 2%.
2200 tons of hydraulic press and microcomputer automatic recording system: check the pressure quality of each large-diameter steel pipe.
