Straight seam welded steel pipe spiral weld pipe

Classification and Standards Pressure transmission fluid, with spiral submerged arc welded pipe SY5036-83, mainly used to transport oil, natural gas pipelines; pressure transmission fluid with high-frequency spiral welded steel pipe SY5038-83, high-frequency welding lap welding method for pressure fluid transfer high frequency spiral welded steel pipe.

Strong pressure steel, plastic, and easy welding and machining molding; general low pressure fluid, with spiral submerged arc welded pipe SY5037-83, using double-sided or single-sided automatic submerged arc welded into the legal system for water, gas , air and steam low pressure liquid delivery SAW pipe.

Common standards now generally divided into spiral pipe: SY/T5037-2000 (Ministry of standard, also known as general fluid pipes with spiral submerged arc welded pipe), GB/T9711.1-1997 (GB, also known as the oil and natural gas industries Technical delivery conditions for steel Part: A grade steel (to the current demanding a GB/T9711.2 B grade steel)), API-5L (American Petroleum Institute, also known as line pipe; which is divided into two PSL1 and PSL2 level), SY/T5040-2000 (pile with spiral weld pipe).

Pile with spiral welded steel pipe (SY5040-83) is a hot-rolled steel coils for the tube, often warm spiral shape, using double-sided submerged arc welding or high frequency welding made for civil engineering structures, piers, carbon seamless steel pipe manufacturer china bridges such as foundation piles with steel. SY/T5037-2000 Oil Ministry is setting standards are generally referred to as the Ministry of standard GB9711.1-1997 GB coil, oil and natural gas industries - Steel pipe, A-level low pressure liquid delivery spiral seam high frequency welded pipe (SY5039-83) is hot rolled steel coils for the tube, often warm spiral shape, using high frequency lap welding method for general low pressure liquid delivery spiral seam high frequency welded steel pipe.

Spiral steel mainly used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction, is one of China’s 20 key products developed. For the transport of liquids: water supply, drainage. For gas transportation: gas, steam, LPG. For structural purposes: as piling pipe for bridges; piers, roads, pipes and other building structures.
