The main purpose of spiral welded pipe and the difference from straight seam welded pipe

Spiral welded pipes are widely used in natural gas, petroleum, chemical, electric power, heating, water supply and drainage, steam heating, pressure steel pipes for hydropower stations, thermal power generation, water sources and other long-distance pipelines and piling, dredging, bridges, steel structures and other engineering fields.

Spiral welded pipes in Haihao Group

Difference from straight seam tube:

LSAW pipes are produced from steel pipes, while spiral welded pipes are produced from hot-rolled coils. The rolling process of hot-rolled strip mills has a series of advantages and has the metallurgical process capability to produce high-quality pipeline steel. The alloy content of the coil is often lower than that of similar grade steel plates, which also improves the weldability of the spiral welded pipe. The material of the spiral welded pipe has better crack resistance than the straight seam steel pipe.

Spiral steel tube and T-welded stee tube

Welding process: The welding methods of spiral welded pipe and straight seam steel pipe are the same, but there are inevitably many T-shaped welds in straight seam welded pipe, so the probability of welding defects is greatly increased.
