FprEN 13121-3

GRP tanks and vessels for use above ground - Part 3: Design and workmanship

This European Standard gives requirements for the design, fabrication, inspection, testing and verification of GRP tanks and vessels with or without thermoplastics lining for storage or processing of fluids, factory made or site built, non-pressurized or pressurized up to 10 bar, for use above ground. Further requirements are presented in normative Annex G.
The terms vessels and tanks as used in this part of EN 13121 include branches up to the point of connection to pipe work or other equipment by bolting and supports, brackets or other attachments bonded directly to the shell.
This part of EN 13121 covers vessels and tanks subject to temperatures between - 40 °C and 120 °C.
Excluded from this part of EN 13121 are:
-   tanks and vessels for the transport of fluids;
-   underground storage tanks;
-   spherical vessels;
-   vessels and tanks of irregular shape;
-   tanks and vessels with double containment where the double wall is considered structural;
-   tanks and vessels which are subject to the risk of explosion, or failure of which may cause an emission of radioactivity;
-   specification for fibre reinforced cisterns of one piece and sectional construction for the storage, above ground, of cold water (see EN 13280).

Oberirdische GFK-Tanks und -Behälter - Teil 3: Auslegung und Herstellung

Dieses Dokument legt Anforderungen für Auslegung, Fertigung, Prüfung und den Nachweis für oberirdische GFK-Tanks und –Behälter, mit oder ohne thermoplastische(r) Auskleidung fest, die im Werk oder auf der Baustelle gefertigt und drucklos oder bis zu 10 bar druckbeaufschlagt sind und zur Lagerung oder Verarbeitung von Fluiden dienen. Weitere Anforderungen sind im normativen Anhang G dargelegt.
Die Begriffe Behälter und Tank im Sinne dieses Dokuments umfassen auch Stutzen(Abzweige) bis zur Verbindung zu Rohrleitungen oder anderen Anlagenteilen, wie Verschraubungen, Unterstützkonstruktionen, Halterungen oder anderen Anbauteilen, die unmittelbar mit der Schale verbunden sind.
Dieses Dokument gilt für Behälter und Tanks, die Temperaturen zwischen −40 °C und 120 °C ausgesetzt sind.
Dieser Teil der EN 13121 gilt nicht für
   Tanks und Behälter für den Transport von Fluiden,
   unterirdische Lagertanks,
   kugelförmige Behälter,
   Behälter und Tanks mit unregelmäßiger Form,
   Tanks und Behälter in doppelwandiger Ausführung, bei denen die Doppelwandigkeit statisch berücksichtigt wird,
   Tanks und Behälter, die bei Explosion oder Undichtheit die Emission radioaktiver Strahlungen zur Folge haben können, und
   einteilige und mehrteilige oberirdische faserverstärkte Tanks für die Lagerung von Kaltwasser (siehe EN 13280).
