In recent years, offshore deep-water dock project has been large-scale construction on the domestic coast, as the bearing capacity of the pile of the deep-water wharf, commonly used spiral weld large diameter piling pipe; In addition, bridges, roads, and high-rise buildings also need piling pipe.

Besides, piling pipe is a structural building material used to support and stabilize a building's foundation. When the soil below a building is loosely packed, it may not offer enough strength to keep the building stable over time.

A pipe piling can be used to distribute the weight of the building deeper into the earth, where the soil is often more tightly packed.

The nominal outside diameter of piling steel pipes: is 219-3620mm

Usually length: 8.0- 12m

Manufacturing methods of spiral welded steel pipe pile 

Spiral Pipe is a strip coil as raw material, often warm extrusion molding, two-wire double-sided submerged arc welding process automatically welded spiral seam steel pipe.

The appearance quality of piling steel pipe

Steel pipe weld surface shall not have cracks, broken arcs, craters and holes, and other defects, the above-mentioned defects of the weld allow welding defects to allow grinding or repair. Pipe to allow the strip rival weld, steel pipe to allow the docking from two pipe butt welding can be submerged arc welding or manual welding process.
