Tube EN 12449 — CW508L — MS — ID30 × 2,5 5 Ordering information In order to facilitate the enquiry, order and confirmation of order procedures between the purchaser and the supplier, the purchaser shall state on his enquiry and order the following information: a) quantity of product required (number of pieces, length or mass); b) denomination (Tube); c) number of this European Standard (EN 12449); d) material designation (see Tables 1 to 8); e) material condition designation (see 4.2 and Tables 9 to 15) if it is other than M; f) nominal cross-sectional dimensions [either outside diameter (OD) and wall thickness or inside diameter (ID) and wall thickness] (see 6.3); g) length, either nominal together with tolerance required, or fixed length (see 6.3.4). NOTE 1 It is advised that the product designation, as described in 4.3, is used for items b) to f). In addition, the purchaser shall also state on the enquiry and order any of the following, if required: h) whether the tubes are for sea water application (see Table 3). If so, the composition limits required; i) test method to be used for the measurement of hardness, i.e. Vickers or Brinell (see 8.3); j) where dimensional tolerances are to be applied, if not on the outside diameter and wall thickness (see 6.3.1); k) whether the tubes are required to pass a drift expanding test (see 6.5.1); l) whether the tubes are required to pass a stress corrosion resistance test (see 6.5.2); m) whether the tubes are required to meet a grain size requirement (see 6.5.3); if so, the grain size limits required; NOTE 2 It is advised to agree the grain size limits between the purchaser and the supplier. n) whether the tubes are required to pass freedom from defects tests (see 6.5.4); if so, which test method is to be used (see 8.5), if the choice is not to be left to the discretion of the supplier, and the acceptance criteria if they are not to be left to the discretion of the supplier; o) whether deburring is required (see 6.4); p) whether special surface quality is required (see 6.4); SIST EN 12449:2016

The tests shall be carried out in accordance with either 8.2 (tensile test) or 8.3 (hardness test). Products in stress relieved condition shall conform to the same mechanical property requirements as for non stress relieved material. 6.3 Dimensions and tolerances 6.3.1 General The geometrical properties of the tubes are defined by outside diameter or inside diameter, wall thickness and length. Normally, tolerances for cross-sectional dimensions are applied on the outside diameter (see 6.3.2) and wall thickness (see 6.3.3) but other possibilities may be agreed between the purchaser and the supplier at the time of the enquiry and order [see Clause 5, list entry j)]. Normally, tubes are supplied in lengths with tolerances agreed between the purchaser and the supplier at the time of the enquiry and order [see Clause 5, list entry g)] but tubes may be ordered as "fixed lengths" (see 6.3.4). 6.3.2 Outside or inside diameter The diameter of the tubes shall conform to the tolerances given in Table 17. 6.3.3 Wall thickness The wall thickness, measured at any point, shall conform to the tolerances given in Table 18.
