Structural Steel Pipe Standard

Structural Steel Pipe can accommodate many different applications including bollards and bumper posts, structural columns, shoring, fencing, piling, racks and rollers. Structural Steel Pipe
mainly used for factories, bridges, ships and other structures. Structure Steel Pipe includes various seamless steel pipe or welded steel pipe for structure, pile pipe, large diameter seamless
steel pipe, large diameter submerged arc welded steel pipe, large diameter seamless steel pipe, large diameter thick wall thickness steel pipe etc.

Seamless Steel Pipe for Structure:

Seamless Steel Pipe for Structure is used seamless steel pipes or seamless steel tubes for general structure and mechanical structure. For the manufacturer of pipes, containers,
equipment, fittings and mechanical structure seamless steel pipe.
Specification:
Outside Diameter: 10.3mm ~ 1013mm
Wall Thickness: 1.7mm ~ 52mm


Welded Steel Pipe for Structure:

Welded steel pipe used in steel structures, bridges, support, building structure pipe, pile pipe. Since the structure steel pipe or structure steel tube requires a lot of pressure.
Structural steel pipe requires high pressure capabilities which means only the steel pipes has greater wall thickness (> 8mm) can be applied as structure steel pipe.
Type of Pipes:
1. LSAW Steel Pipe - Logitudinal Submerged Arc Welded Steel Pipe
2. SSAW Steel Pipe - Spiral Submerged Arc Welded Steel Pipe
3. SAWH Steel Pipe - Submerged Arc Welded Helical Steel Pipe
Specification:
LSAW Steel Pipe: Outside Diameter: 406mm ~ 1625mm, Wall Thickness: 6.0mm ~ 75mm
SSAW Steel Pipe/SAWH Steel Pipe: Outside Diameter: 219mm ~ 4064mm, Wall Thickness: 3.2mm ~ 40mm
