  How to confirm the specifications of cold-drawn steel pipes?

  Cold-drawn steel pipes are widely used in machinery manufacturing, automotive components, hydraulic and pneumatic systems due to their high dimensional accuracy, tight tolerances, and excellent surface finish. However, incorrect specification confirmation often leads to assembly failure, performance mismatch, rework, and schedule delays. This article will briefly introduce how to confirm the specifications of cold-drawn steel pipes.

  Square tube vs round tube: selection guide

  Choosing between square hollow sections (SHS) and circular hollow sections (CHS) is a common challenge in construction, machinery manufacturing, and infrastructure projects. An incorrect choice may lead to higher costs, structural inefficiency, installation difficulties, or safety risks. This guide provides a clear selection framework to help you decide quickly and professionally based on real engineering scenarios.

  What are the welding processes for stainless steel pipes?

  In stainless steel pipe production, a flat steel strip is first formed into a cylindrical shape. After forming, the strip edges must be welded together to create a continuous tube. The quality of this longitudinal weld has a decisive influence on pipe formability, burst strength, and downstream processing performance. Therefore, selecting an appropriate welding technology is critical to meeting the stringent quality requirements of modern manufacturing. Currently, the most widely used welding processes for stainless steel pipes include high-frequency (HF) welding, gas tungsten arc welding (GTAW / TIG), and laser welding.

  Square tube and round tube cross-sectional comparison

  In engineering design, comparing round tubes and square tubes with the same cross-sectional area is essentially an evaluation of structural efficiency under equal material usage. Since material strength remains constant, the differences in mechanical performance arise purely from cross-sectional geometry. These differences are well-established, quantitatively verifiable, and carry strong engineering guidance value for structural selection.
