1 Scope This European Standard specifies the technical delivery conditions in two test categories for seamless tubes of circular cross section, made of weldable alloyed fine grained 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.

test category 5 Classification and designation 5.1 Classification 5.1.1 This Part of EN 10216 covers steel grades in four qualities (see Table 2 and Table 4):  the basic quality (P . N, Q);  the elevated temperature quality (P . NH, QH);  the low temperature quality (P . NL1, QL, QL1);  the special low temperature quality (P . NL2, QL2). 5.1.2 In accordance with the classification system in EN 10020, the steel grades P275NL1, P355N, P355NH and P355NL1 are classified as alloy quality steels and the other steel grades are classified as alloy special steels. 5.2 Designation 5.2.1 For the tubes covered by this Part of EN 10216 steel, the designation consists of:  the number of this Part of EN 10216;
plus either  the steel name in accordance with EN 10027-1; or  the steel number allocated in accordance with EN 10027-2. 5.2.2 The steel name is designated by:  the capital letter P for pressure purposes;  the indication of the specified minimum yield strength for the lowest applicable wall thickness group expressed in megapascals (Table 4);  one of the additional symbols N, NH, NL1, NL2, Q, QH, QL, QL1 or QL2 (see 5.1.1, Table 2 and Table 4). 6 Information to be supplied by the purchaser 6.1 Mandatory information The following information shall be supplied by the purchaser at the time of enquiry and order: a) the quantity (mass or total length or number); b) the term "tube"; c) the dimensions (outside diameter D and wall thickness T or a set of dimensions covered by option 10) (see Table 7); SIST EN 10216-3:2014

Unless option 1 is specified, the tubes may be either hot or cold finished at the discretion of the manufacturer. The terms “ hot finished “ and “ cold finished “ apply to the condition of the tube before it is heat treated in accordance with 7.2.3. Option 1: The tubes shall be cold finished before heat treatment. 7.2.3 The tubes shall be supplied in the relevant heat treatment conditions as specified in Table 1 and Table 4.

See 7.2.5.
7.2.4 In case of steel grade P355N and P355NH, normalizing may be replaced by normalizing forming. 7.2.5 For steel grade P460 it may be necessary to apply delayed cooling or additional tempering after normalizing. For N-steel grades, accelerated cooling after austenitising may be necessary in order to achieve the intended structure and material properties in case of wall thickness above 25 mm or T/D > 0,15.
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 with the requirements of this Part of EN 10216. In addition, the general technical delivery requirements specified in EN 10021 shall apply. Tubes shall be suitable for hot and cold bending provided the bending is carried out in an appropriate manner. When tubes are specified in the order by d, dmin or Tmin the following formulae, with all terms in mm, shall apply for the calculation of outside diameter Dc, inside diameter dc and wall thickness Tc, instead of D, d and T for the relevant requirements in 7.2.5, 8.4.1.4, 10.2.2.2, 11.3, 11.8.1, 11.9, 11.11.4, 12.1 and Table 1, footnote c, Tables 4, 5, 6, 7, 10, 12, 15 and 16: Dc = Td2+

When welding tubes produced in accordance with this Part of EN 10216, account should be taken of the fact that the behaviour of the steel during and after welding is dependent not only on the steel, but also on the applied heat treatment and the conditions of preparing for and carrying out the welding. 8.2.2 Product analysis Option 3: A product analysis for the tubes shall be supplied. Table 3 specifies the permissible deviations of the product analysis from the specified limits on cast analysis given in Table 2. 8.3 Mechanical properties 8.3.1 The mechanical properties of the tubes shall conform to the requirements in Tables 4, 5, 6, 7, Annex A, and in 11.3, 11.4, 11.5, 11.6 and 11.7. SIST EN 10216-3:2014

Elevated temperature properties given in Table 5 and Table 6 shall be verified for NH-grades at 400 °C. The properties at elevated temperature given in Table 5 and Table 6 for steel grades P355NH, P460NH, P620QH and P690QH, apply for the corresponding low and special low temperature quality steels if option 5 is specified.
The properties at the elevated temperature given in Annex A for steel grades P275NL1 and P275NL2 apply if option 5 is specified. Option 5: Elevated temperature properties given in Tables 5, 6 and Annex A shall be verified for NL- and QL-grades at the highest temperature for which a value is given.
