Steel tubes for precision applications – Part 3: Welded cold sizes tubes.
This European Standard specifies the technical delivery conditions for welded cold sizes steel tubes of circular cross section for precision applications.
Tubes according to this document are characterized by having precisely defined tolerances on dimensions and a specified maximum surface roughness. Typical fields of application are in the vehicle, furniture and general engineering industries.
Electric-Resistance-Welded Metallic-Coated Carbon Steel Mechanical Tubing. This specification covers round, square, rectangular and special shape, electric-resistance welded mechanical tubing, either zinc-coated (galvanized), zinc-iron alloy-aluminum (galvannealed) or 55% aluminum-zinc alloy-coated steel sheet.
This specification covers electric-resistance-welded carbon and alloy steel tubes for use as mechanical tubing. This specification covers mechanical tubing made from hot- or cold-rolled steel.
