Using hot-rolled steel coil as the pipe billet,
The spiral welded steel pipe for piles is manufactured from hot-rolled steel coils as the pipe billet, formed into a spiral shape at room temperature, and then welded using double-sided submerged arc welding or high-frequency welding. It is commonly used as steel pipes for foundation piles in civil engineering structures, docks, bridges, and other applications.
Welded by high-frequency lap welding,
For pressure-bearing fluid transportation, spiral submerged arc welded steel pipes are primarily employed in pipelines conveying oil and natural gas. The spiral seam high-frequency welded steel pipe for pressure-bearing fluid transportation is welded using the high-frequency lap welding method, suitable for the transportation of pressurized fluids.
Strong pressure-bearing capacity and good plasticity,
Steel pipes exhibit strong pressure-bearing capabilities and good plasticity, facilitating welding and processing into various shapes. To extend the service life of pipelines, anti-corrosion treatment has become a standard step in the production process of pipe materials.
Relatively strong anti-corrosion capability,
Spiral steel pipes possess relatively strong anti-corrosion capabilities, making them suitable for modified anti-corrosion materials. This not only enhances the pipeline's anti-corrosion properties but also ensures no contamination of drinking water. For sewage transportation, where anti-corrosion requirements are less stringent, using cement mortar for anti-corrosion can also prolong the pipe's lifespan. The quality of spiral steel pipes must meet the requirements of their intended use.
