EN10217-1: Non-Alloy Steel Tubes with Specified Room Temperature Properties
EN 10217-1 defines the technical delivery criteria for qualities TR1 and TR2 of electric welded and submerged arc welded tubes of circular cross-section, with specified room temperature attributes, manufactured from non-alloy grade steel. It is designed for use at room temperature and in sprinkler or fire protection systems, and it is available in a variety of thicknesses.
