Spiral steel pipes come in various types and sizes; the following is just a partial list of specifications provided:

Available diameters (DN) range from 20mm (DN20) to 2000mm (DN2000), with common sizes including: DN50, DN100, DN150, DN200, DN250, DN300, DN350, DN400, DN450, DN500, DN600, DN700, DN800, DN900, DN1000, DN1200, DN1400, DN1600, DN1800, and DN2000.

The above data is for reference only. If needed, it is recommended to consult the manufacturers of spiral steel pipes.

Corrosion-resistant spiral steel pipe is a type of spiral steel pipe that has been specially treated, with a protective coating added to its outer surface to enhance its corrosion resistance and extend its service life.

The anti-corrosion spiral steel pipe has the same outer diameter and wall thickness specifications as the standard spiral steel pipe. However, during the manufacturing process, a protective anti-corrosion coating must be applied to the pipe surface to prevent corrosion and damage to the pipeline.

Multiple options are available for corrosion-resistant materials, commonly including high polymers such as epoxy resin, polyurethane, polyester, and esters, as well as special materials like corrosion-resistant coatings and linings.

Corrosion-resistant spiral steel pipes are widely used in various fields such as oil, chemical, power, and drainage industries. Particularly in harsh environments like oceans, deserts, and saline-alkali soils, their corrosion resistance and stability are even more superior.
