Spiral seam steel pipe is to roll low-carbon carbon structural steel or low-alloy structural steel strip into a tube blank according to a certain spiral angle (called forming angle), and then connect the tube blank into a steel pipe by welding. Spiral seam steel pipe is mainly used for transporting oil and natural gas pipelines, with strong pressure-bearing capacity and good plasticity, which is easy to weld and processSpiral seam submerged arc welded steel pipe for general low-pressure fluid transportation is made of double-sided automatic submerged arc welding or single-sided welding method for general low-pressure fluid transportation such as water, gas, air and steam.
SY T5037 spiral seam steel pipe is the 97th version of the national standard spiral steel pipe standard formulated by the Ministry of Petroleum, and it is also one of the most mainstream spiral steel pipe standards under the current national standard. The basic provisions in the standard include the following:
1.Forming method: Spiral seam welded pipe adopts double-sided submerged arc welding or single-sided arc welding process.
2.Material: Spiral seam welded pipe uses seamless pipe (GB T 8163) or hot-rolled pipe as raw material.
3.Classification: According to the different conveying mediums, it is divided into spiral seam welded pipes suitable for the corresponding fluid conveying pressure made by welding high-quality carbon structural steel (GB T 3091) for general low-pressure fluid transportation, high-pressure fluid transportation and low-pressure fluid transportation.
4.Specifications and dimensions: expressed in nominal diameter (DN), DN15 DN600mm.
5.Dimensional deviation: in accordance with the provisions of GB T 17395.
6.Coating: Different anti-corrosion coatings can be applied as required.
7.Quality requirements: in accordance with GB T 97111 and the requirements of the SY T 5037 standard.
SY T5037 spiral seam steel pipe is widely used in the field of oil and natural gas transportation, and has the following advantages:
1.High efficiency, energy saving, environmental protection: SY T5037 spiral seam steel pipe adopts double-sided submerged arc welding process, which has high welding efficiency and short production cycle, which can save energy and resources. At the same time, the process produces less harmful gases, which is conducive to environmental protection.
2.High strength and high toughness: SY T5037 spiral seam steel pipe is made of high-quality steel, which has high strength and toughness, and can withstand greater pressure and tensile force.
3.High conveying efficiency: Due to the small frictional resistance of the SY T5037 spiral seam steel pipe, the fluid transfer efficiency is high, which can reduce energy consumption and reduce operating costs.
4.Easy installation: SY T5037 spiral seam steel pipe adopts longitudinal seam welding process, which is easy and quick to install, and can shorten the project cycle.
5.Strong adaptability: SY T5037 spiral seam steel pipe can adapt to a variety of complex geographical environments and climatic conditions, such as deserts, plateaus, severe cold and other regions.
6.Easy maintenance: Since the SY T5037 spiral seam steel pipe adopts the longitudinal seam welding process, if there are leakage and other problems, the maintenance is convenient and fast.
In a word, SY T5037 spiral seam steel pipe has a wide range of application prospects in the field of oil and gas transportation. With the continuous advancement of technology and the continuous change of market demand, the standard is also constantly being revised and improved. In the future, with the continuous improvement of environmental awareness and the adjustment of energy structure, the application prospect of SY T5037 spiral seam steel pipe will be broader.
