Common standards for Spiral Pipe Assemblys are generally divided into: SY/T5037-2018 (ministry standard, also known as spiral seam submerged arc welded steel pipe for common fluid transportation pipeline), GB/T9711.1-1997 (national standard, also known as technical conditions for delivery of oil and gas industry transportation steel pipe part I: grade a steel pipe (strict requirements include GB/T9711.2 grade B steel pipe)), API-5L (american petroleum institute, also known as pipeline steel pipe; which is divided into PSL1 and PSL2 two levels), SY/T5040-92 (pile with spiral seam submerged arc welded steel pipe).
Spiral Pipe Application of solvent, emulsion cleaning steel surface, in order to remove oil, grease, dust, smooth agent and similar organic matter, but it can not remove the appearance of steel rust, oxide skin, welding flux, etc., so in the production of anti-corrosion only as auxiliary measures.
Spiral Pipe Machines are inspected by on-line continuous ultrasonic automatic flaw detector, which ensures 100% NDT coverage of spiral welds. If there are defects, automatic alarm and spraying marks, production workers according to this at any time to adjust the process parameters, timely elimination of defects.
Spiral pipe is also called spiral steel pipe or spiral welded pipe. It is made of low carbon structural steel or low alloy structural steel strip according to a certain spiral angle (called forming angle), and then the pipe seam is welded. It can produce large diameter steel pipe with narrow strip.
