Which ASTM Standard applies to samples of structural steel pipe?

The ASTM A53 standard specifically addresses the requirements for seamless and welded black and hot-dipped galvanized steel pipe for use in mechanical and pressure applications, as well as for ordinary uses in the construction of pipe systems. This standard covers various grades of steel pipe, making it broadly applicable to structural steel piping applications.

A53 is particularly relevant for structural applications where the pipe will be used in construction, such as in the support of structural frames, scaffolding, or other load-bearing solutions. Its specifications ensure that the pipe meets minimum mechanical properties to safely carry loads under intended conditions.

The other standards listed are focused on different types of steel products: A500 pertains to cold-formed welded and seamless carbon steel structural tubing, A36 defines the specifications for carbon structural steel plates, shapes, and bars of structural quality, and A572 specifies high-strength low-alloy structural steel. Each of these standards serves specific materials or applications that do not directly relate to the structural steel pipe outlined in ASTM A53.
