Steel tubes for precision applications - Technical delivery conditions - Part 3: Welded cold sized tubes
This document specifies the technical delivery conditions for welded, dimensionally rolled precision steel tubes with a circular cross-section with a nominal outside diameter D <= 193.7 mm and with square and rectangular cross-sections. This document can also be applied to welded cut-to-size pipes with a different cross-section. Pipes according to this document are characterized by precisely defined tolerances and a specified maximum surface roughness. Typical areas of application are vehicle construction, the furniture industry and mechanical engineering in general.
