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.

Difference of PSL1 and PSL2(API 5L)
The API 5L has two standards, PSL1 and PSL2, which are very different from each other. I'll talk more about the differences between PSL1 and PSL2.
Production Process of Pipe Fitting
There are many kinds of processing methods for pipe fittings.
The Future of Steel Pipe Development
The future of steel pipe development is looking promising, according to expert analysis and data. The price of carbon steel pipe is predicted to bounce back this year, with China leading the way in increasing steel consumption demands. This is due to a series of government initiatives aimed at stimulating domestic demand, including the construction of affordable housing and infrastructure projects. The demand for structural steel pipe is also on the rise, thanks to state investment in housing and engineering projects. With private investment projects also gaining popularity, the steel pipe market is set to thrive in 2017.
