It is recommended that the level 3 personnel be certified in accordance with EN or, at least, an equivalent to it. The operating authorization issued by the employer shall be in accordance with a written procedure. NOTE The definition of level 1, 2 and 3 can be found in appropriate standards e. EN and prEN Unless option 1 is specified, the tubes di be either hot or cold finished at the discretion of the manufacturer. The tubes shall be cold finished before heat treatment.
In addition, the general technical delivery requirements specified in EN 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 equations, all in millimetres, shall apply for the calculation of outside diameter Dc, inside diameter dc and wall thickness Tc, instead 01216-2 D, d and T for the relevant requirements in clauses 8.
NOTE When welding tubes produced in accordance with this Part of this ENaccount 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.
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. The decision shall be at the discretion of the manufacturer, but shall be stated to the customer at the time of ordering. Proof strength Rp0,2 shall be verified.
The test temperature shall be specified at the time of ordering. Page 16 EN Normally, the finish and surface condition shall be such that any surface imperfections requiring dressing can be identified. All dressed areas shall blend smoothly into the contour 1021-2 the 102116-2.
This requirement does not apply to surface imperfection with a depth equal or less 0,3 mm 8. Unless option 7 is specified, the choice of the test method is at the discretion of the manufacturer. The test method for verification of leak tightness in accordance with The tubes of test category 2 shall subjected to a non-destructive testing for the detection of transverse imperfections in accordance with The tubes of test category 2 shall be subjected to a non-destructive testing for the detection of the laminar imperfections in accordance with Deviations from straightness over any one metre length shall not exceed 3 mm.
The ends shall be free from excessive burrs. The tubes shall be delivered with bevelled ends see figure 1. Page 20 EN Preferred outside diameters and wall thicknesses have been selected from ENV and are given in table 6.
NOTE 10216-22 which are different from those in table 6 may be agreed. The tubes shall be delivered in accordance withone of the following sets of dimensions as specified at the time of ordering: Page 23 EN The delivery length range shall be agreed at the time of ordering.
Tubes shall be delivered in exact lengths and the length shall be specified at the time of ordering. For the tolerances, see 8.
