• 24.20.Z Production of steel pipes, tubes, hollow sections and connectors

What 24.20 includes

• Manufacture of seamless tubes and pipes of circular or non-circular cross section and of blanks of circular cross section, for further processing, by hot rolling, hot extrusion or by other hot processes of an intermediate product, which can be a bar or a billet obtained by hot rolling or continuous casting
• Manufacture of precision and non-precision seamless tubes and pipes from hot-rolled or hot-extruded blanks by further processing, by cold drawing or cold rolling of tubes and pipes of circular cross section and by cold drawing only for tubes and pipes of non-circular cross section and hollow profiles
• Manufacture of welded tubes and pipes of an external diameter exceeding 406,4 mm, cold formed from hot-rolled flat products and longitudinally or spirally welded
• Manufacture of welded tubes and pipes of an external diameter of 406,4 mm or less of circular cross section by continuous cold or hot forming of hot
• Or cold-rolled flat products and longitudinally or spirally welded and of non-circular cross section by hot or cold forming into shape from hot
• Or cold-rolled strip longitudinally welded
• Manufacture of welded precision tubes and pipes of an external diameter of 406,4 mm or less by hot or cold forming of hot
• Or cold-rolled strip and longitudinally welded delivered as welded or further processed, by cold drawing or cold rolling or cold formed into shape for tube and pipe of non-circular cross section
• Manufacture of flat flanges and flanges with forged collars by processing of hot-rolled flat products of steel
• Manufacture of butt-welding fittings (e.g. elbows and reductions), by forging of hot-rolled seamless tubes of steel
• Threaded and other tube or pipe fittings of steel

What 24.20 excludes
