Welded pipe, that is, welded steel pipe, is a seamed steel pipe. How much do you know about this product? Today, Yan Xinsen domain Xiaobian will introduce you to everyone, let everyone deepen the impression on the welded pipe.
The production method of the welded pipe is a process in which the steel plate and the steel strip are bent into the required cross-sectional shape and size by various forming methods, and the welding seam is welded by different welding methods to obtain the steel pipe: the strip blank → forming It is tube-shaped → welded into tube → finished.
Welded pipes can be divided into straight seam welded pipes and spiral welded pipes according to the form of welds. Straight seam welded pipe has simple production process, high production efficiency, low cost and rapid development. Most of the smaller diameter welded pipes are straight seam welded.
The strength of the spiral welded pipe is generally higher than that of the straight welded pipe. It is possible to produce a welded pipe with a larger diameter by using a narrow blank, and it is also possible to produce a welded pipe having a different pipe diameter with a blank of the same width. However, the weld length is increased and the production speed is lower than that of the straight welded pipe of the same length. Large diameter welded pipes are mostly spiral welded.
