Product Description

API 5l PSL2 natural gas pipeline 

Spiral pipe Standard & × Q345A Solenoid the classification # @ Q345D spiral purposes
Spiral Profile

"Is also called a cylinder or spiral of the spiral body. Spiral tube outer diameter of about 30 nm, an inner diameter of about 10 nm, and adjacent helical pitch of about 11 nm. Spiral every 1 week 6 nuclear bodies surrounded H1 histone is located in the inner surface of the spiral cavity, plays an important role to maintain the structure of the spiral by nuclear bodies composed of 10 nm fiber spiral to form a 30 nm thick fiber, so that the length of the DNA further The compressed six times.

The the spiral pipe Standard & × Q345A Solenoid Category # @ Q345D spiral uses spiral characteristics

The the spiral characteristics: Longitudinal production process is simple, high production efficiency, low cost, rapid development. The strength of the spiral welded pipe is generally higher than longitudinally welded pipes, can narrow the billet production of large diameter welded pipe, billet production of different diameters of the same width of the welded pipe can also be used. However, compared with the same length as the straight seam pipe, the increase in length of the weld 30 to 100%, and a lower production speed. Therefore, most of the smaller caliber welded pipe straight seam welded, spiral welded large diameter pipe they use.

Spiral classification 

Spiral picture

Spiral and its standard classification: pressure transmission fluid spiral submerged arc welded pipe (SY5036-83) is mainly used to transport oil, natural gas pipeline; pressure transmission fluid with spiral seam high frequency welded steel pipe (SY5038-83) with high frequency welded lap welding method for pressure transmission fluid spiral seam high frequency welded steel pipe. Pressure steel capacity, good plasticity, easy welding and machining molding; generally low pressure liquid delivery spiral submerged arc welded pipe (SY5037-83), using double-sided automatic submerged arc welding by one side into the legal system for water, low pressure gas, air and steam submerged arc welded pipe for fluid transport.

Spiral standard

The spiral of commonly used standard is generally divided into: SY/T5037-2000 (Ministry of standard, also called ordinary fluid pipes with spiral submerged arc welded pipe), GB/T9711.1-1997 (GB, also known as the oil and gas industry conveyor Pipe Technical delivery conditions: A steel pipe (to demanding a GB/T9711.2 B grade steel)), API-5L (American Petroleum Institute, also known as line pipe; divided into PSL1 and PSL2 two level), SY/T5040-92 (pile with spiral seam submerged arc welded pipe)

Spiral pipe material

The the spiral pipe Material: Q235A spiral, Q23b Solenoid, 1Cr17, 0Cr13 spiral spiral, 00Cr19Ni11 spiral, 1Cr18Ni9 spiral, 0Cr18Ni11Nb spiral. Q345 spiral L245 spiral L290 spiral X42 X46 of X70 X80 X95 spiral
