EN 10294-1 is a standard for pipes and tubes that are used in mechanical engineering applications. It covers the requirements for circular, unalloyed steel hollow sections with thicknesses from 2mm to 40mm and nominal widths up to 500mm. These products are widely used in automotive, machine building, construction, mining, and other industries.
The steel used to make EN 10294-1 Pipe and Tubes are typically unalloyed, with a carbon content of 0.17% or less. It also needs to have an average grain size between ASTM No 5 and 8, must be free from any visible lamination or scale, and the surface finish should be clean and free from any visible defects. The pipes and tubes must also conform to the mechanical properties specified in the standard, such as yield strength, tensile strength, and elongation.
