Pressurized fluid conveying, using spiral seam submerged arc welding steel pipe SY5036-2000, is mainly used for conveying oil, natural gas pipeline; Pressurized fluid conveying with high frequency welding steel pipe spiral seam SY5038-2000, using high-frequency welded lap welding method, used in pressurized fluid conveying spiral seam high frequency welding steel pipe.Steel tube confined ability, good plasticity, easy to welding and processing molding;
General low-pressure fluid conveying, spiral seam submerged arc welding steel pipe SY5037-2000, adopt double automatic submerged arc welding or one side welding into legal system for water, gas, air and steam general low-pressure fluid conveying with submerged arc welding steel pipe.Commonly used standards of the spiral steel pipe can be divided into: SY/T5037-2008 (solid, also known as the common fluid conveying pipe with spiral seam submerged arc welding steel pipe), GB/T9711.1-2008 (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; which can be divided into PSL1 and PSL2 two levels), SY/T5040-2008 (with spiral weld steel pipe pile). SY/T5037-2008 is the oil ministry set standards are generally called targets helical tube, GB/T9711.1-2008 national oil and gas industry conveying pipe, A level General low-pressure fluid conveying spiral seam high frequency welded steel pipe (SY5039-2000) is a hot rolled steel coil tube billet, often spiral forming temperature, using high-frequency lap welding welding for general low-pressure fluid conveying spiral seam high frequency welding steel pipe. Pile with spiral weld pipe (SY5040-2000) is a hot rolled steel coil tube billet, often spiral shape, made of double-sided submerged arc welding or high frequency welding, used in civil construction, port, bridge pile foundation with steel pipe.
