Abstract
This European Standard specifies the product characteristics, test methods and performance criteria for circular, non-alloy steel tubes suitable for welding, threading and other jointing methods and provides a number of options for coatings and the finish of tube ends. This document covers two grades of steel tubes of specified outside diameter (D) 10,2 mm to 323,9 mm (thread size 1/8 to 12) in two series, medium and heavy, and three types of designated thicknesses.
Tubes manufactured according to this document can be used for the conveyance of fluids as well as for other applications.
Other joining methods include, but are not limited to, grooved fittings and compression ends (for which fittings are defined in prEN 10344).
NOTE Compliance of a product with this document does not confer a presumption of fitness of the product for the transport of water intended for human consumption within the meaning of Regulation (EU) No 305/2011. However, until the operation of the envisaged European Acceptance Scheme for construction products in contact with water intended for human consumption and the revision of the present document, suitably coated or lined products complying with this document can be used for the transport of water intended for human consumption if they comply with the relevant national, regional or local regulatory provisions applicable in the place of use.
