European foreword
This document (prEN 13480-9:2018) has been prepared by Technical Committee CEN/TC 267
“Industrial piping and pipelines”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a mandate given to CEN by the European Commission and the
European 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.
This European Standard EN 13480, Metallic industrial piping, consists of nine interdependent and not
dissociable parts which are:
— Part 1: General;
— Part 2: Materials;
— Part 3: Design and calculation;
— Part 4: Fabrication and installation;
— Part 5: Inspection and testing;
— Part 6: Additional requirements for buried piping;
— Part 7: Guidance on the use of conformity assessment procedures [CEN/TR];
— Part 8: Additional requirements for aluminium and aluminium alloy piping;
— Part 9: Additional requirements for nickel and nickel alloys piping.
Although these parts may be obtained separately, the parts are interdependent. As such the manufacture
of metallic industrial piping requires the application of all the relevant parts in order for the requirements
of the European Standard to be satisfactorily fulfilled.
This European Standard will be maintained by a Maintenance MHD working group whose scope of
working is limited to corrections and interpretations related to the EN 13480 series.
The contact to submit queries can be found at http://www.unm.fr (en13480@unm.fr). A form for
submitting questions can be downloaded from the link to the MHD website. After subject experts have
agreed an answer, the answer will be communicated to the questioner. Corrected pages will be given
specific issue number and issued by CEN according to CEN Rules. Interpretation sheets will be posted on
the website of the MHD.

5 Materials
5.1 General
The general requirements of EN 13480-2:2017 shall apply with the following additions/exclusions in 5.2-
5.5.
NOTE There are presently no European Standards specifically for nickel or nickel alloys for pressure purposes.
This document is therefore limited to:
1) Harmonized standards as listed in Table A.2;
2) Nickel and nickel alloys having EMAs as listed in Table A.3;
These commonly used materials are suitable for, and may be employed in, the design and
manufacture of piping according to this document.
3) Materials for which the manufacturer produces a Particular Materials Appraisal (PMA).
These may be used only when they meet the requirements in Subclauses 5.1 to 5.5 of this document.
5.2 Material grouping system
EN 13480-2:2017, Annex A is not applicable to metallic industrial piping of nickel and nickel alloys and
is replaced by Annex A of this document.
The grouping system for nickel and its alloys as given in CEN/ISO TR 15608:2013 is shown in Table A.1
of this document.
Only material having a minimum elongation after fracture greater than 25 % shall be used for
construction of metallic industrial piping.
Materials which have mechanical properties enhanced by precipitation hardening are excluded from this
document, unless they are to be used for bolting applications.
5.3 Material documentation
Materials for pressure bearing parts compliant with the requirements of this document shall be
accompanied by inspection documentation in accordance with EN 10204:2004.
The type of inspection document shall be in 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 taken into account.
5.5 Lamellar tearing
Failure by lamellar tearing is not normally a defect of nickel and nickel alloys.
6 Design
6.1 General
All the design methods included in EN 13480-3:2017 shall apply, with the following amendments, given
in 6.2 – 6.5.

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 1.
If any material is subjected to subsequent heat treatment (for example, 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 manufacturer’s works. The nominal design
stress shall then be calculated in accordance with Table 1 using the values from this test. If this design
stress is lower than 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 designs 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 fabrication.

6.3 Creep design
Where sufficient material data are available, creep design may be applied to nickel and nickel alloys using
the formulae and approach of EN 13480-3:2017.
6.4 Piping under external pressure
The requirements for austenitic steels in EN 13480-3:2017, 9.2.2 shall apply to nickel and nickel alloys.
6.5 Fatigue design
For loads up to 1 000 equivalent full pressure cycles no fatigue analysis is required.
Above 1 000 cycles the requirements of EN 13445-3:2014, Clause 17 shall apply with the following
modifications:
The application of EN 13445-3:2014, Clause 17 (see EN 13445-3:2014, 17.4.4) to nickel and nickel alloys
