The difference between seamless steel tube and welded steel tube
Seamless steel pipe VS welded steel pipe: 1. Seamless steel pipe is a kind of strip steel with no joints around and a hollow section, which is widely used as a pipeline for conveying fluids. Compared with solid steel, it is lighter in weight with the same bending and torsional strength. It is an economical section steel and is widely used in the manufacture of structural and mechanical parts, such as automobile transmission shafts, oil drill pipes, bicycle frames and construction steel. Scaffolding etc. 2. Welded steel pipes are steel pipes made of steel plates or steel strips that are crimped and welded. The production process of welded steel pipe is simple, with many varieties and specifications, less equipment and high production efficiency, but its comprehensive strength is lower than that of seamless steel pipe. With the rapid development of continuous rolling production of high-quality strip steel and the advancement of welding inspection technology, the quality of welds has...
