Spiral Seam Submerged Arc Welded Steel Pipe for Pressure Fluid Transport

Spiral Seam Submerged Arc Welded Steel Pipe for Pressure Fluid Transport

SY5036-83 spiral submerged arc welded steel pipe for pressure fluid transportation of spiral seam submerged arc welded pipe is mainly used for oil and natural gas pipeline; SY5038-83 spiral seam high frequency welded steel pipe for pressure fluid transportation is welded by high frequency lap welding method, which is used for pressure fluid transportation of spiral seam high frequency welded steel pipe. The steel pipe has strong pressure bearing capacity, good plasticity, and is easy to weld and process. SY5037-2000 spiral submerged arc welded steel pipe for bulk transportation. The commonly used standards for submerged arc welded steel pipe for general low pressure fluid transportation, such as water, gas, air and steam, which are made by double-sided automatic submerged arc welding or single-sided welding, are generally divided into SY/T5037-2000 (industry standard, also known as spiral submerged arc welded steel pipe for general fluid transmission pipeline), GB/T9711.1-1997 (national standard, also known as stone). Technical Conditions for Delivery of Pipe for Oil and Natural Gas Industry Part I: Class A Steel Pipe (GB/T9711.2 B Steel Pipe and GB/T9711.3 C Steel Pipe), API-5L (American Petroleum Association Standard, also known as Pipeline Steel Pipe; which is divided into PSL1 and PSL2 levels), SY/T5040-92 (Spiral Submerged Arc Welded Pipe for Piles) Spiral Seam Submerged Arc Welded Pipe for Pressure Fluid Transportation (SY5036-83) is hot-rolled steel. The coiled pipe blank is spirally formed at normal temperature and welded by double-sided submerged arc welding. It is used for spiral seam steel pipe conveying pressure fluid. Steel pipe has strong pressure bearing capacity and good welding performance. It is safe and reliable to use after various strict scientific tests and tests. The steel pipe has large diameter, high conveying efficiency and saves investment in laying pipelines. It is mainly used for pipelines to transport oil and natural gas. Products are widely used in water works, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction, is one of the 20 key products developed in China. For liquid transportation: water supply and drainage. For gas transportation: gas, steam, liquefied petroleum gas. For structural purposes: as piling pipes, bridges, wharfs, roads, construction pipes, etc. Double-sided submerged arc welding spiral steel pipe
