SSAW STEEL PIPE is a commonly used type of steel pipe, typically used for transporting fluids, gases, and other materials. It is made by continuously bending and welding a strip of steel. Spiral steel pipes have the following advantages:
High strength: due to the use of spiral winding technology, the strength of the steel pipe is higher than that of other types of steel pipes.
Strong corrosion resistance: the surface of spiral steel pipes can be treated with galvanizing, hot-dip galvanizing, or spraying to increase their corrosion resistance.
Easy installation: spiral steel pipes can be customized as needed and can be welded on site according to actual site conditions, making them convenient and fast to install.
Widely used: spiral steel pipes can be used to transport oil, natural gas, water, and various other chemicals.

The surface finish of spiral steel pipes is typically aimed at protecting the pipe walls against corrosion and enhancing its appearance. These surface finishing methods include painting, coating,ect.
Painting: Painting involves applying a thin layer of paint onto the surface of the steel pipe to provide surface protection and aesthetics. The painted coating can be selected according to customer requirements. Mostly painting in black, red....
Coating: Coating is typically a plastic coating applied onto the surface of the spiral steel pipe to enhance surface protection. It can provide better protection and appearance by selecting the appropriate plastic material. Most are anti-corrosion and insulation coatings.
Depending on different requirement from the clients and the pipes delivery condition needs.
