Precautions for selecting raw materials for LSAW steel pipes

LSAW steel pipe is a steel pipe with a weld seam parallel to the longitudinal direction of the steel pipe which usually divided into metric welded steel pipes, welded thin-walled pipes, transformer cooling oil pipes, and so on. The production process of straight seam welded pipe is simple, with high production efficiency, low cost, and rapid development. The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. Narrow billets can be used to produce larger diameter welded pipes, and billets of the same width can also be used to produce welded pipes of different diameters. However, compared to straight seam pipes of the same length, the weld length increases by 30-100% and the production speed is lower.

When selecting raw materials, it is also important to remember the following:

1. Reasonably select the steel grade, specifications, allowable deviations, and production method of the required raw materials based on the quality requirements of the LSAW steel pipes produced;

2. The raw materials of LSAW steel pipes have no internal or external surface defects;

3. The LSAW steel pipe packaging is neat and firm, without loose rolls or tower shapes;

4. For LSAW steel pipes with the same batch specification, the steel grade, furnace number, and batch number should be clearly distinguished.
