Steel pipes can be classified according to the rolling process, whether there are seams, and the cross-sectional shape.

According to the classification of rolling process, steel pipes can be divided into hot-rolled steel pipes and cold-rolled steel pipes;

According to whether the steel pipe has seams, the steel pipes are divided into seamless steel pipes and welded steel pipes. Among them, commonly used welded steel pipes can be divided into three types: high-frequency welded pipes, longitudinal submerged arc welded pipes, and spiral submerged arc welded pipes.
