Steel Pipes

Industry Definition & Scope
The steel pipes industry involves the manufacturing, processing, and distribution of hollow cylindrical products made primarily from steel, used for conveying fluids, gases, solids, and structural applications across virtually every sector of the global economy. As one of the most fundamental industrial components, steel pipes form the circulatory system of modern infrastructure, energy distribution, construction, and manufacturing.
