Attention is draw
19、n to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the Europea
20、n Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document.

BS EN 13445-10:2015EN 13445-10:2015 (E) 5 1 Scope This Part 10 of this European Standard specifies requirements for unfired pressure vessels and their parts made of nickel and nickel alloys (see 3
23、.1) in addition to the general requirements for unfired pressure vessels under EN 13445-1:2014, EN 13445-2:2014, EN 13445-3:2014, EN 13445-4:2014 and EN 13445-5:2014.

29、e alloys which contain a minimum of 30 % nickel and contain more nickel than iron 4 General requirements The general requirements of EN 13445-1:2014 shall apply. BS EN 13445-10:2015EN 13445-10:2015 (E) 6 5 Materials 5.1 General The general requirements of EN 13445-2:2014 shall apply with the followi
30、ng additions/exclusions in 5.2 5.5. NOTE There are presently no European Standards specifically for nickel or nickel alloys for pressure purposes. This part 10 of EN 13445 is therefore limited to European Approval of Materials (EAM) or the use of Particular Materials Appraisal (PMA). These may be us
31、ed when they meet the requirements in 5.1 to 5.5 of this part 10 of EN 13445. 5.2 Material grouping system Annex A of EN 13445-2:2014 is not applicable to pressure vessels of nickel and nickel alloys and is replaced by Annex A of this part 10 of EN 13445. The grouping system for nickel and its alloy
32、s is shown in Table A.1 of this part 10 of EN 13445. Only material having a minimum elongation after fracture greater than 25 % shall be used for construction of pressure vessels. Materials which have mechanical properties enhanced by precipitation hardening are excluded from this part of EN 13445,
33、unless they are to be used for bolting applications. 5.3 Material documentation Materials for pressure bearing parts compliant with the requirements of this European Standard shall be accompanied by inspection documentation in accordance with EN 10204:2004. The type of inspection document shall be i
34、n accordance with EN 764-5:2014 and include a declaration of compliance to the material specification. 5.4 Prevention of brittle fracture There are no general requirements for nickel and nickel alloys at temperatures down to 196 C. However, the specific requirements of individual EAMs/PMAs shall be
35、taken into account. 5.5 Lamellar tearing Failure by lamellar tearing is not normally applicable to nickel and nickel alloys. 6 Design 6.1 General All the design methods included in EN 13445-3:2014 shall apply, with the following amendments, given in 6.2 6.5. Physical properties of nickel and nickel
36、alloys are given in Annex B. 6.2 Time-independent nominal design stress The design stress for nickel and nickel alloy materials entering service without any subsequent heat treatment shall be evaluated in accordance with Table 6.2-1. If any material is subjected to subsequent heat treatment (for exa
37、mple, in the manufacture of dished ends) representative material test coupons shall be heat treated with the components and subjected to the same mechanical tests as used to certify the material at the manufacturers works. The nominal design stress shall then be calculated in accordance with Table 6
38、.2-1. If this design stress is lower than BS EN 13445-10:2015EN 13445-10:2015 (E) 7 that used in the original calculations, the design of that component and any other related components shall be repeated using the nominal design stress derived from the properties of the heat treated material. For de
39、signs using nickel and nickel alloys attention is drawn to the effect of heat treatment on the materials, and care should therefore be taken when determining the thickness of the materials that will receive subsequent heat treatments during manufacture.

Heat treatment of tubular products after cold forming shall be carri
