Description :
The commonly used standards for spiral steel pipes are generally divided into: SY/T5037-2008 (departmental standard, also known as spiral seam submerged arc welded steel pipes for ordinary fluid transportation pipelines), GB/T9711.1-2008 (national standard, also known as technical delivery conditions for petroleum and natural gas industry transportation steel pipes: Grade A steel pipes (GB/T9711.2 Grade B steel pipes with strict requirements)), API-5L (American Petroleum Institute, also known as pipeline steel pipes); It is divided into two levels: PSL1 and PSL2, and SY/T5040-2008 (spiral welded steel pipes for piles).
SY/T5037-2008 is a standard established by the Ministry of Petroleum, generally referred to as a departmental standard.
GB/T9711.1-2008 National Spiral Pipe, Steel Pipe for Petroleum and Natural Gas Industry Transportation, Grade A
The spiral seam high-frequency welded steel pipe (SY5039-2000) for general low-pressure fluid transportation is made of hot-rolled steel strip coil as the pipe blank, which is formed by constant temperature spiral welding and welded using high-frequency lap welding method for general low-pressure fluid transportation spiral seam high-frequency welded steel pipe.
Spiral welded steel pipe for piles (SY5040-2000) is made of hot-rolled steel strip coil as the billet, formed by constant temperature spiral welding, and made by double-sided submerged arc welding or high-frequency welding. It is used as a steel pipe for foundation piles in civil construction structures, docks, bridges, etc

development:
Despite the impact of the economic crisis, Spiral Steel Pipe Company is gradually recovering and embracing a better tomorrow. Spiral steel pipes have played a significant role in transporting gas and transportation.
With the planning and construction of multiple major pipeline projects at home and abroad, high value-added products such as large deformation pipeline steel, high-strength hot bending pipes, and thick specification low-temperature pipe fittings have shown good market competitiveness and significant market demand. However, domestic enterprises have made relatively slow progress in developing this series of products. In order to develop high value-added and large deformation pipeline steel, hot bending pipe steel, low-temperature pipe fittings steel for pipeline stations, X100 straight seam submerged arc welded pipe, spiral seam submerged arc welded pipe, hot bending pipe, and spiral steel pipe suitable for industrial applications as soon as possible.
