Commonly used standards of the spiral pipe can be divided into: the SY/T5037-2000 (solid, also known as the common fluid conveying pipe with spiral seam submerged arc welding steel pipe), GB/T9711.1-1997 (national standard, also known as oil and gas industry conveying pipe delivery technical conditions in the first part: grade A steel pipe (GB/T9711.2 strict grade B steel pipe)), API 5 l (American petroleum institute, also known as the pipeline steel pipe;It can be divided into TWO grades: PSL1 and PSL2), SY/T5040-92 (spiral welded pipe for pile); Spiral welded pipe is mainly used for conveying oil and natural gas. Spiral pipe has strong bearing capacity and good plasticity. spiral pipe is easy to be welded and processed.Submerged arc welded steel pipe with spiral seam for general low-pressure fluid transport is made by double-side automatic submerged arc welding or single-side welding. It is used for general low-pressure fluid transport such as water, gas, air and steam.The outside diameter of the spiral pipe distributed by the company is ￠219-2420mm and the wall thickness is 5-32mm. The material of the spiral pipe is Q235A,Q235B,OCr13,1Cr17, etc.
