OEM LSAW Steel Pipe

Product Specification

LSAW steel pipe manufacturing process

LSAW (Longitudinal Submerged Arc Welding) steel pipe is manufactured using the submerged arc welding process. The process involves several steps that ensure the quality and integrity of the final product.

The first step in the LSAW steel pipe manufacturing process is the preparation of the steel plate. The plate is cleaned to remove any impurities, and then it is bent into the desired shape using a bending machine. The bending process is carried out in a way that creates a "U" shape or a "J" shape.

After the plate is bent, it is welded lengthwise using a submerged arc welding process. In this process, an arc is used to heat the plate to its melting point, and then a filler material is added to form the weld. The weld is formed through a combination of heat and pressure, which ensures a strong joint.

Once the welding is complete, the pipe is cooled and inspected for any defects. The pipe is then cut to the required length, and the ends are prepared for welding.

In the final step, the ends of the pipe are welded together to form a continuous length of pipe. This is done using a high-frequency welding process or a submerged arc welding process. The welded joint is then inspected to ensure its quality and integrity.
