Relationship between this European Standard and the Essential Requirements of EU Directive 97/23/EC . 29 Bibliography . 30
1 Scope This European Standard specifies the technical delivery conditions in two test categories for seamless tubes of circular cross section, with specified low temperature properties, made of non-alloy and alloy steel. NOTE Once this standard is published in the Official Journal of the European Union (OJEU) under Directive 97/23/EC, presumption of conformity to the Essential Safety Requirements (ESR) of Directive 97/23/EC is limited to technical data of materials in this standard and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of this specific item of equipment to verify that the ESRs of the Pressure Equipment Directive are satisfied, needs to be done by the designer or manufacturer of the pressure equipment, taking also into account the subsequent manufacturing processes which may affect properties of the base materials. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

7 Manufacturing process 7.1 Steelmaking process The steelmaking process is at the discretion of the manufacturer with the exception that the open hearth (Siemens-Martin) process shall not be employed unless in combination with a secondary steelmaking or ladle refining process. Steels shall be fully killed. NOTE This excludes the use of rimming, balanced or semi-killed steel. 7.2 Tube manufacture and delivery conditions 7.2.1 All NDT activities shall be carried out by qualified and competent level 1, 2 and/or 3 personnel authorized to operate by the employer. The qualification shall be in accordance with ISO 11484 or, at least, an equivalent to it. It is recommended that the level 3 personnel be certified in accordance with EN ISO 9712 or, at least, an equivalent to it. The operating authorization issued by the employer shall be in accordance with a written procedure. NDT operations shall be authorized by level 3 NDT individual approved by the employer. NOTE The definition of level 1, 2 and 3 can be found in appropriate standards, e.g. EN ISO 9712 and ISO 11484. 7.2.2 The tubes shall be manufactured by a seamless process.
- -- -- +QT f (880 to 930) -- 770 to 820 water or oil 540 to 600 a N = Normalizing ; QT = Quenching and Tempering; NT = Normalizing and Tempering. b Where two types of heat treatment are specified for a steel grade, the application depends on wall thickness and T/D ratio. The decision is left to the manufacturer but shall be reported in the inspection document. c When choosing the cooling medium, the influence of other parameters, such as dimensions and quenching temperature, on properties and crack susceptibility should be taken into account. Other cooling media such as synthetic quenchants may also be used. d Tempering can occasionally be necessary after normalizing; the decision shall be left to the discretion of the manufacturer but shall be stated to the customer at the time of enquiry and order. Steel tubes treated in such a way shall be designated by the steel name supplemented by the symbol “+NT “. e Cooling at still air or accelerated cooling. f An additional prenormalizing treatment, in the temperature range indicated may be necessary for this grade. In such a case, the manufacturer shall inform the purchaser.
8 Requirements 8.1 General When supplied in a delivery condition indicated in 7.2 and inspected in accordance with Clauses 9, 10 and 11, the tubes shall conform to the requirements of this Part EN 10216. In addition, the general technical delivery requirements specified in EN 10021 shall apply. SIST EN 10216-4:2014
