Black Spiral Welded Steel Pipe, also known as Black SSAW Steel Pipe, is a double-sided submerged arc welded spiral pipe supplied without coating or surface treatment. It offers flexible specifications, reliable strength, and cost-effective performance for piling, structural projects, and industrial pipeline applications. ZHONGTIAN provides customized solutions with various diameters, wall thicknesses, and steel grades.

Small Diameter Spiral Welded Steel Pipe is a spiral welded steel pipe manufactured through spiral forming and double-sided submerged arc welding technology. With diameters generally below DN800, it features flexible specifications, reliable weld quality, and good structural strength. It is widely used in municipal pipelines, industrial systems, water projects, and construction applications. ZHONGTIAN provides customized SSAW steel pipe solutions as a professional manufacturer in China.

Large Diameter Spiral Welded Steel Pipe, also called Large Diameter SSAW Steel Pipe, is designed for large-scale pipeline systems requiring extended diameter ranges and reliable structural performance. Manufactured from hot rolled steel coils by spiral forming and double-sided submerged arc welding, it delivers excellent strength, dimensional stability, and efficient installation for long-distance engineering projects.

Thick Wall Spiral Welded Steel Pipe, also known as Thick Wall SSAW Steel Pipe or Heavy Wall Spiral Welded Steel Pipe, is a high-strength large diameter welded pipe manufactured from thick hot rolled steel strips through spiral forming and double-sided submerged arc welding technology. Its thick wall design provides excellent pressure resistance, structural rigidity, and durability for demanding engineering environments.

Thin Wall Spiral Welded Steel Pipe, also called Thin Wall SSAW Steel Pipe, is a lightweight large diameter welded pipe manufactured from hot rolled steel coils using spiral forming and double-sided submerged arc welding technology. With thin wall design, cost efficiency, and reliable performance, it is widely used in low-pressure fluid transportation, municipal pipelines, industrial applications, and lightweight structures. ZHONGTIAN is a professional steel pipe manufacturer in China providing customized solutions.

Spiral Welded Steel Pipe, also known as SSAW (Spiral Submerged Arc Welded Steel Pipe), is a large-diameter welded pipe manufactured from hot rolled steel coils through spiral forming and double-sided submerged arc welding technology. It features excellent load-bearing capacity, stable mechanical performance, strong deformation resistance, and cost efficiency, making it suitable for fluid transportation, infrastructure construction, and industrial pipeline applications.
