Pipe, steel, black and hot-dipped zinc-coated
Standard specification for pipe, steel, black and hot-dipped, zinc-coated, welded and seamless.
Carbon Steel — Industrial Product
Hot rolled carbon steel pipe supplied to ASTM A53 / ASTM A106 / API 5L for structural, fluid conveyance and engineering applications.
Overview
Hot Rolled Steel Pipe combines low-carbon carbon steel with the cost efficiency of hot rolling for reliable mechanical performance and consistent dimensional control. The mill finish and wide size range make the pipe suited to general structural framing, fluid conveyance, building services, low-pressure piping and general engineering applications. Supplied to ASTM A53 / ASTM A106 / API 5L with mill test certification per EN 10204 3.1, it supports global procurement across construction, energy and general industrial supply chains.

FAQ
Most enquiries reduce to a small set of recurring technical questions.
Hot-rolled carbon pipe is formed by piercing a billet at elevated temperature and rolling to final dimension. It is suitable for general low / medium pressure service.
Grade A has lower tensile and yield strength requirements; Grade B has higher strength and is more commonly used for pressure and structural applications.
Yes. Hot-dip galvanizing to ASTM A53 is available for both welded and seamless construction. Internal galvanizing is generally not performed.
Standard single random length 5 - 7 m, double random 11 - 13 m. Cut-to-length and exact-length supply are available.
Plain end, beveled end (30°), threaded and coupled (NPT / BSP), and grooved end preparations are available.
