CAEN Code 2420: Manufacture of tubes, pipes, hollow profiles and related fittings, of steel

This class includes:

• Fabricarea, prin laminare la cald, extrudare la cald sau alte procedee la cald, a tuburilor şi profilelor fără sudură, de secţiune circulară sau de altă formă, precum şi a semifabricatelor de secţiune circulară, pentru laminarea ulterioară, din bare sau bilă obtained prin laminare la cald sau turnare continuă
• manufacture of precision and non-precision seamless tubes and pipes, processed from hot-rolled or hot-extruded blanks through cold drawing or cold rolling for tubes and pipes with a circular cross-section; cold drawing is also used for tubes and pipes with non-circular cross-sections 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, such as elbows and reductions, by forging of hot rolled seamless tubes of steel
• threaded and other tube or pipe fittings of steel
