How to distinguish between SMLS tube and ordinary steel pipe

Ordinary steel pipes, such as water pipes, are usually welded through a curved steel plate, and then a weld can be found; the coarser diameter is usually a spiral weld.


SMLS pipes are usually molten steel which is formed by the process of backfilling and stretching after ring gap slit, so there is no weld. In terms of performance, especially the pressure capacity is much higher than that of ordinary steel pipe, so it is often used in high voltage equipment.


Such as the pipe connection of the hydraulic equipment. The weak links and the weld quality are the main factors affecting the overall performance of the common steel pipe weld. People living in the North usually have water pipes or heating pipes, which are frozen and exploded in winter. The pipe is not a SMLS pipe. Ordinary steel pipes, such as water pipes, are usually welded through a curved steel plate, and then a weld can be found; the coarser diameter is usually a spiral weld.
