ERW pipe, short for Electric Resistance Welded pipe, is a type of steel pipe formed by welding the edges of a steel strip or plate together using electric resistance welding (ERW) technology. Here is a detailed explanation of ERW pipes, covering their manufacturing process, characteristics, applications, and advantages/disadvantages:

Hollow Structural Section (HSS) steel pipes are construction steel pipes with high tensile strength and load-bearing applications. There are three broad types of HSS steel pipes: circular, rectangular, and square. HSS steel pipes are critical in structural applications due to their high strength-to-weight ratio. They see widespread use in infrastructural projects, industrial settings, and construction work. In this guide, we will cover the most crucial aspects of HSS. It will give you a comprehensive idea of how HSS pipes can help your project.

Seamless pipe manufacturing commences with a solid steel billet. This chunk of metal goes through a heating process to reach an ideal malleability and temperature. Then, workers pierce and stretch it, transforming it into a hollow tube.

As the name suggests, the outside diameter of a pipe or tube is the length of its diameter measured from one external surface to the other. To measure the outside diameter, read the distance between the cross-section of the pipe as a whole.

Seamless steel pipes do not have a welding seam. The primary raw material for making seamless pipes is steel billets. Billets are perforated using a piercing tool, resulting in a jointless steel tube. These pipes are straight and do not have any welded corners or angles. Seamless steel pipes are manufactured by hot rolling, cold rolling, or cold drawing. Seamless steel pipes have excellent bending and torsion strength. For this reason, they are seen in high-pressure applications. They compose oil rig pipes, automobile drive shafts, chemical plants, and construction support structures.
