Common spiral steel pipe outer diameters include 219mm, 325mm, 406mm, 508mm, 610mm, 711mm, 800mm, 820mm, 850mm, 914mm, 1000mm, 1020mm, 1200mm, 1220mm, 1420mm, 1520mm, 1680mm, and 1800mm.

These spiral steel pipes with various outer diameters are widely used in industrial and municipal engineering fields, such as water supply and drainage projects, wastewater treatment plants, and hydraulic engineering. Different outer diameters of spiral steel pipes can be selected to meet the actual engineering requirements.

Corrosion-resistant spiral steel pipe is a type of spiral steel pipe that has undergone special treatment, with a protective coating applied to the outer surface to enhance its corrosion resistance and extend its service life.

Corrosion-resistant spiral steel pipes have the same outer diameter and wall thickness specifications as standard spiral steel pipes. However, during the manufacturing process, a protective anti-corrosion coating must be applied to the pipe surface to safeguard against corrosion and damage.

There are various options for material choices for corrosion-resistant coatings, commonly including materials like epoxy resin, polyurethane, polyester, and esters, as well as special materials such as corrosion-inhibiting paints and linings.

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