Foreword
This document (EN 13480-3:2002/A4:2010) has been prepared by Technical Committee CEN/TC 267
“Industrial piping and pipelines”, the secretariat of which is held by AFNOR.
This Amendment to the European Standard EN 13480-3:2002 shall be given the status of a national standard,
either by publication of an identical text or by endorsement, at the latest by November 2010, and conflicting
national standards shall be withdrawn at the latest by November 2010.
Attention is drawn 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
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 document includes the text of the amendment itself. The corrected pages of EN 13480-3 will be delivered
as issue 12 of the standard.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard : Austria, Belgium, Bulgaria, Croatia, Cyprus,

1 Addition of Annex Q
Add the following new Annex Q: "
Annex Q
(informative)

Simplified pipe stress analysis
Q.1 General
The pressure design of all piping components shall be carried out in accordance with the rules of EN 13480-3.
Stresses due to sustained loads, occasional and exceptional loads, thermal expansion and alternating loads
have to be taken into account to meet the code stress requirements for their particular load case.
Q.2 Simplified procedure
Q.2.1 General
As a deviation from Q.1, the stresses from gravitational forces and temperature fluctuations can be simply
determined (see EN 13480-3:2002, 12.2.10) in accordance with Q.2.2 and Q.2.3 independent of the other
stresses in each case.
This procedure shall be applied by experienced personal only. It does not yield information about the loads at
anchor points and shall not be applied to piping, operating in the creep range.
This method only applies to piping which is not buried. For buried piping, additional considerations, for
example with regard to vertical soil loads, restrained expansion due to soil resistance, or mining subsidence
are necessary. These are not covered by the simplified method.
Q.2.2 Specification of allowable spacing of supports
The specification of the allowable spacing of supports, limits the effect of the dead weight of the piping on the
deflections and the stresses. Thus it is possible to consider the internal pressure and the dead weight of the
piping separate from each other. Proof of the permissibility of the support spacing is provided if, for steel
pipes, the support distances given in Table Q.1 are not exceeded and the explanatory notes regarding the
specification of support distances are considered. For other parameters, e.g. other materials, the Table Q.1
can be converted in accordance with the information in the explanatory notes of Table Q.1.
Q.2.3 Check of elasticity
To meet the stress limitations in the load case thermal expansion the piping need to have a sufficient
elasticity. This is normally achieved by a routing that allows for bending and torsional deflection due to
compensating measures. A design calculation for elasticity is not required if the leg lengths comply with the
conditions of Figure Q.2. It is assumed that torsional stresses are less significant due to the routing.
Examples of application of Figure Q.2 and explanatory notes are given in Q.9
