Spiral Welded Steel Pipe

Spiral Welded Steel Pipe’s materials include carbon steel, alloy steel, stainless steel, and corrosion-resistant steel, catering to different media transportation needs. Outer diameters range from 219mm to 3500mm, and wall thicknesses from 3mm to 50mm, supporting large-scale production to meet the needs of large-scale engineering projects. Standard lengths are 6 meters and 12 meters, but customization is available. Surface treatments include galvanizing, spraying, and anti-corrosion coating.

Tianjin Shuncheng Industrial's Spiral Welded Steel Pipes are produced directly from steel ingots and billets using hot or cold rolling processes, resulting in a seamless pipe structure. The core feature lies in its integrated molding design. The seamless nature ensures uniform strength distribution within the pipe body, maintaining stable strength and durability under internal pressure or external stress. This effectively reduces safety hazards in high-pressure environments, making it the preferred pipe material for high-pressure, high-temperature, and corrosive conditions in industrial applications.

The Spiral Welded Steel Pipes use high-quality steels such as 20#, 45#, 16Mn, alloy steel, and stainless steel as raw materials, combined with advanced surface treatment processes such as galvanizing, spraying, and anti-corrosion coatings. This results in not only strong tensile and compressive strength but also resistance to corrosion from acids, alkalis, and salts, extending service life. With a wide adaptability range, it can operate stably within a temperature range of -50°C to 600°C. Pressure ratings can be flexibly selected from medium or high pressure specifications according to actual scenarios, easily handling various harsh working environments.
