18、 the following text after the final sentence: Requirements for peaking (out-of-roundness caused by misalignment of (welded) joints or local irregularities in vessel profile) are given in Annex H. Add annex H as follows: EN 286-1:1998/A2:2005 (E) 4 Annex H (normative) Requirements for peaking H.1 Loc
19、al irregularities in vessel profile Irregularities in profile (e.g. dents, buckling, flats on nozzle positions) shall be smooth and the depth shall be checked by a 20 gauge and shall not exceed the following values: a) 2 % of the gauge length; or b) 2,5 % of the gauge length provided that the length
20、 of the irregularities does not exceed one quarter of the length (with a maximum of 1 m) of the shell part between two circumferential joints. Greater irregularities require proof by calculation or strain gauge measurement that the stresses are permissible. H.2 Peaking on longitudinal butt welds Whe
21、n irregularity in the profile occurs at the welded joint and is associated with “flats“ adjacent to the weld, the irregularity in profile or (peaking) shall not exceed the values given in Tables H.1 and H.2. Measurement for peaking shall be made by means of a 20 profile gauge (or template), see Figu
22、re H.1, or other types of gauge such as a bridge gauges or needle gauges. For outwards peaking two readings shall be taken, P1and P2on each side of the joint, at any particular location, the maximum peaking is determined using Equation (H.1) P = 0,25 (P1+ P2) (H.1) The inwards peaking P shall be mea
23、sured. The inside radius of the gauge shall be equal to the nominal outside radius of the vessel.
