Standard specifications of small diameter seamless steel pipes
Small-diameter seamless steel pipes refer to seamless steel tubes with relatively small outer diameters. They can be categorized into seamless small-diameter pipes and straight-seam (welded) small-diameter pipes. In general, pipes with an outer diameter between 4 mm and 89 mm fall into the small-diameter range. Although widely used, many users have limited familiarity with their specifications. These pipes are produced and inspected in accordance with standards such as ASTM A106, ASTM A53, EN 10216, and GB/T 8163, which define their chemical composition, mechanical properties, and dimensional tolerances.

Square tube size calculation
Square tubes (SHS steel) are widely used in construction, machinery manufacturing, and various structural applications. They are typically produced by forming cold-rolled or hot-rolled steel sheets into a hollow square section. Thanks to their geometry, square tubes offer high strength, good compressive performance, low weight, easy processing, and a broad range of available specifications. To support engineering design, procurement, and fabrication, it is essential to understand how to calculate square tube dimensions, theoretical weight, cross-sectional area, and standard size classifications. The following provides a complete and practical guide.
