Commonly used standards for spiral steel pipes are generally divided into: (Ministry of Standards, also known as spiral seam submerged arc welded steel pipes for common fluid transportation pipelines), (National standard, also known as Petroleum and Natural Gas Industry Delivery Steel Pipe Delivery Skill Conditions: Grade A steel pipes (to date Strict request (American Petroleum Institute, also called pipeline steel pipe; there are two grades of PSL1 and PSL2), (spiral welded steel pipe for piles).

It is the standard set by the Ministry of Petroleum, which is generally called the national standard spiral pipe, the petroleum natural gas industry transport steel pipe, the A-level common low-pressure fluid transport spiral seam high-frequency welded steel pipe is made of hot-rolled steel coil, and the temperature is often spirally formed , Select high-frequency lap welding for welding high-frequency welded steel tubes for spiral low-frequency fluid transportation. Spiral welded steel pipe for piles is made of hot-rolled steel coil as a billet, which is often hot spiral formed, and is made of double-sided submerged arc welding or high-frequency welding. It is used for steel pipes for foundation piles in civil construction, docks, bridges, etc. .

Steel pipes bring great convenience to our lives. For example, we may use water in ordinary days. Assuming there is no support from the pipeline system, then these things will not be easy to apply. Although the pipeline system has brought great support to the delivery profession.

Spiral steel pipe is not only used to transport fluids and powdered solids, exchange thermal energy, manufacture mechanical parts and containers, it is still an economic steel. The use of steel pipes to manufacture grids, pillars, and mechanical supports for building structures can reduce weight, save 20 to 40 percent of metal, and can complete factory mechanized construction.
