Steel Pipes and Tubes

Shunchen Industrial's Pre-Galvanized Round Steel Tubing for Outdoor Scaffolding is a round steel tube designed for temporary construction structures, working platforms, access systems, and other applications that require reliable tubular support. The round cross-section provides balanced structural performance, while the pre-galvanized surface offers additional protection against moisture and general outdoor exposure.

Shunchen’s Spiral Welded Pipe for Oil Transportation is engineered for long-distance, large-diameter oil transmission pipelines where structural reliability and corrosion resistance are critical. The spiral welded structure provides consistent strength along the pipe body, making it suitable for onshore crude oil and product pipelines, pump stations, and industrial fluid systems. Available with internal and external anti-corrosion systems, the pipe can be supplied to project-specific diameters and wall thicknesses to match pipeline design pressure and installation conditions.

Tianjin Shunchen supplies Spiral Welded Steel Pipe with Large Diameter for water transmission, oil and gas pipelines, chemical processing, mining, and other infrastructure applications. The pipes are manufactured by forming steel strip or plate into a spiral shape and welding the helical seam continuously. Available outer diameters range from 219 mm to 3500 mm, with wall thicknesses from 3 mm to 50 mm. Standard pipe lengths are 6 m and 12 m, with other lengths available according to project requirements.
