1.SY036-2000 is mainly used to transport oil and gas pipelines and is used to carry out fluid pressure;
2.Spiral seam high pressure fluid conveying high frequency welding steel tube sy5038-2000, high frequency lap welding welding, high frequency welding spiral weld pipe conveying fluid.Steel tube bearing capacity, plastic good, easy to weld processing.
3.The low pressure fluid conveying screw embedded arc sy5037-2000 welded steel pipe is used for the automatic welding or welding method of double - face submerged arc welding, which can be used for the pipe water, gas, air and steam to carry the low pressure fluid.
4.The common standard of spiral welded pipe is generally divided into: system/t5037-2008 (standard, also known as spiral normal fluid pipeline submerged arc welding steel pipe, national standard (GB).Steel tube (GB/t9711.2 grade strictly B), API -5l (API), also known as line pipe; There are two levels of PSL1 and PSL2, and SY/t5040-2008 (spiral weld piling pipe).
5.SY/T5037-2008 is the oil ministry set standards are generally called targets.
6.GB/T9711.1-2008 national spiral pipe, petroleum and natural gas transmission pipe, Grade A
7.The low pressure fluid conveying pipe is a hot roller blank with spiral seam high frequency welding (sy5039-2000). The high frequency spiral seam is used to weld the low-pressure fluid pipe.
Spiral-welded steel pipe pile (sy5040-2000) is a kind of hot rolling billet, often spiral shape, made of double-sided submerged arc welding or high frequency welding, used in civil construction structure, wharf, bridge foundation pile and steel pipe.
