Classification: stainless steel, carbon steel, low alloy steel, alloy steel, etc.
According to the process: double-sided submerged arc welding, single-sided submerged arc welding.
According to the purpose: spiral steel pipe for fluid transportation and spiral steel pipe for pile.
According to the pressure-bearing capacity: general low-pressure fluid transportation, pressure-bearing general fluid transportation pipeline.
According to manufacturing standards, it is divided into: national standard, American standard, Japanese standard, Russian standard, etc.
Features: strong corrosion resistance and plasticity; At the same time, spiral welded pipe is also a kind of welded pipe equipment, and its strength is generally higher than that of straight welded pipe. Welded pipes with larger diameter can be produced from narrow blanks, or welded pipes with different diameters can be produced from blanks with the same width. Uses: Spiral welded pipe is mainly used in tap water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation and urban construction in China. Used for liquid transportation: water supply and drainage. Used for gas transportation: gas, steam, liquefied petroleum gas. Used for structure: used for piling pipes and bridges; Pipes for docks, roads, building structures, etc.
