(Main)Metallic industrial piping - Part 6: Additional requirements for buried piping
Metallic industrial piping - Part 6: Additional requirements for buried piping
This document specifies requirements for industrial piping either totally buried or partly buried and partly run in sleeves or similar protection. It is used in conjunction with the other six parts of
EN 13480:2024 series.
Where buried piping subject to this standard connects to piping installed under other jurisdiction such as pipelines, the transition can be made at a closing element e.g. an isolating or regulating valve separating the two sections. This can be close to the boundary of the industrial site, but can be inside or outside the boundary.
Operating temperature up to 75 °C.
NOTE For higher temperatures reference can be made to EN 13941-1:2019+A1:2021 and EN 13941 1:2019+A1:2021, but it is kept in mind, that CEN/TC 107 only deals with pre-insulated piping with temperatures up to 140 °C and diameters up to 800 mm, which is state of the art for these products.
Metallische industrielle Rohrleitungen - Teil 6: Zusätzliche Anforderungen an erdgedeckte Rohrleitungen
Dieses Dokument legt Anforderungen an ganz oder teilweise erdgedeckte industrielle Rohrleitungen fest, die teilweise in Schutzrohren oder ähnlichen Schutzvorrichtungen verlaufen. Es muss in Zusammenhang mit den anderen sieben Teilen der EN 13480:2024 angewendet werden.
Werden erdgedeckte Rohrleitungen nach dieser vorliegenden Norm an Rohrleitungen angeschlossen, die unter eine andere Zuständigkeit fallen, z. B. Fernrohrleitungen, dann sollte der Übergang an einem Absperrorgan vorgenommen werden, z. B. an einem Absperr- oder Regelventil, durch das die beiden Abschnitte getrennt werden. Dies sollte in unmittelbarer Nähe des Grenzbereiches des Betriebsgeländes erfolgen, kann jedoch inner- oder außerhalb dieser Grenze sein.
Arbeitstemperatur bis 75 °C.
ANMERKUNG Bei höheren Temperaturen sollte auf EN 13941-1:2019+A1:2021 und EN 13941 1:2019+A1:2021 verwiesen werden, wobei jedoch berücksichtigt werden sollte, dass CEN/TC 107 nur vorummantelte Rohrleitungen mit Temperaturen bis 140 °C und Durchmessern bis 800 mm behandelt, die den neuesten Stand der Technik dieser Produkte darstellen.
Tuyauteries industrielles métalliques - Partie 6: Exigences complémentaires pour les tuyauteries enterrées
Le présent document prescrit les exigences concernant les tuyauteries industrielles, soit complètement enterrées, soit partiellement enterrées et partiellement placées dans des gaines ou des protections similaires. Elle est à utiliser conjointement avec les six autres parties de la série EN 13480:2024.
Lorsque les tuyauteries enterrées soumises à la présente norme sont raccordées à des tuyauteries installées soumises à d'autres réglementations comme les canalisations de transport, la transition peut être réalisée au niveau d'un élément de fermeture comme par exemple une vanne d'isolation ou de régulation séparant les deux sections. Cette transition peut être située à proximité de la limite du site industriel, toutefois elle peut être située à l'intérieur ou à l'extérieur de la limite.
Température de service jusqu'à 75 °C.
NOTE Pour des températures élevées, il peut être fait référence à l’EN 13941-1:2019+A1:2021 et l’EN 13941 1:2019+A1:2021, mais il faut garder à l'esprit que le CEN/TC 107 ne traite que des tuyauteries
pré-isolées pour des températures allant jusqu'à 140 °C et des diamètres allant jusqu'à 800 mm, ce qui est la pointe de la technologie en ce qui concerne ces produits.

European foreword
This document (EN 13480-6:2024) has been prepared by Technical Committee CEN/TC 267 “Industrial piping
and pipelines”, the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by December 2024, and conflicting national standards shall be withdrawn
at the latest by December 2024.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 13480-6:2017.
This new edition incorporates the Amendments which have been approved previously by CEN members, and
the corrected pages up to Issue 2 without any further technical change. Annex Y provides details of significant
technical changes between this European Standard and the previous edition.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For the relationship with EU Legislation, see informative Annex ZA, which is an integral part of this document.
This European Standard EN 13480 for metallic industrial piping consists of eight 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;
CEN/TR 13480-7, Guidance on the use of conformity assessment procedures;
Part 8: Additional requirements for aluminium and aluminium alloy piping.
Although these Parts may be obtained separately, it should be recognized that the Parts are inter-dependant.
As such the manufacture of metallic industrial piping requires the application of all the relevant Parts in order
for the requirements of the 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 EN 13480. The contact to submit queries can be found at
https://unm.fr/en/maintenance-agencies/maintenance-agency-en-13480/.
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. Interpretation sheets will be
posted on the website of the MHD.
Amendments to this new edition may be issued from time to time and then used immediately as alternatives
to rules contained herein. These amendments will be consolidated within EN 13480:2024 in accordance with
the maintenance system of EN 13480 series approved by CEN/BT Decision C172/2021.
Any feedback and questions on this document should be directed to the users’ national standards body. A
complete listing of these bodies can be found on the CEN website.
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, Czech
