Spiral piling pipe

近年来，海上深水码头项目一直是国内沿海的大规模建设，作为堆桩的承载力，普通螺旋焊缝大直径桩管;此外，桥梁，道路，高层建筑也需要打桩管。

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.

管桩桩可用于将建筑物的重量分配到地球中，土壤往往更加紧密。

堆积钢管的标称外径：219-3620mm

通常长度：8.0-12M

螺旋焊接钢管桩的制造方法

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.

Appearance quality of piling steel pipe

钢管焊接表面不得有裂缝，破碎的弧形，陨石坑和孔等缺陷，上述焊缝的缺陷允许焊接缺陷允许研磨或修复。管道允许条带竞争焊接，钢管允许两种管道对接焊接可以浸没电弧焊接或手动焊接工艺。
