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.
Where buried piping subject to this standard connects to piping installed under other jurisdiction such as pipelines, the transition should be made at a closing element e.g. an isolating or regulating valve separating the two sections. This should be close to the boundary of the industrial site, but may be inside or outside the boundary.
Operating temperature up to 75 °C.
NOTE   For higher temperatures reference should be made to EN 13941+A1:2010, but it should be 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 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 13941:2009+A1:2010 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 relatives aux 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 l’EN 13480.
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, il est recommandé que la transition soit réalisée au niveau d'un élément de fermeture comme par exemple une vanne d'isolation ou de régulation séparant les deux sections. Il est recommandé que cette transition soit 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 convient de faire référence à l’EN 13941+A1:20102, mais il convient de garder à l'esprit que 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.

Kovinski industrijski cevovodi - 6. del: Dodatne zahteve za vkopane cevovode

Ta dokument določa zahteve za industrijske cevovode, ki so v celoti vkopani ali delno vkopani in tečejo v oklopih ali podobni zaščiti. Uporablja se skupaj z ostalimi šestimi deli standarda EN 13480.
Če so vkopane cevi iz tega standarda povezane s cevmi, ki so vgrajene pod drugo pristojnostjo, kot so cevovodi, naj bi se pri zaključnem elementu naredil prehod, npr. izolacijski ali regulacijski ventil, ki ločuje odseka. Ventil naj bi bil blizu meje industrijske strani, vendar je lahko znotraj ali zunaj meje.
Obratovalna temperatura je največ 75 °C.
OPOMBA: Referenčni standard za višje temperature je standard EN 13941+A1:2010, vendar je treba upoštevati, da standard CEN/TC 107 obravnava samo izolirane cevovode s temperaturami do 140 °C in premeri do 800 mm, kar predstavlja najsodobnejše izdelke.
