Explosion diverters

An explosion diverter is used to divert explosions propagating through ducts, thus preventing flame jet ignition and pressure piling in connected protected enclosures. It will reduce the risk of flame transmission.
This European Standard describes the basic design of a pipe-in-pipe diverter and specifies the testing requirements and the application of explosion diverters.
This European Standard covers:
- a test method for assessing the efficacy of explosion diverters;
- design rules for a type of pipe-in-pipe diverter;
- demands to venting device on diverter;
- installation requirements;
- maintenance requirements;
- marking.
This European Standard considers dust/air explosive atmospheres only.

Explosionsschlote

Ein Explosionsschlot wird zum Ableiten oder Umlenken von sich in Rohrleitungen ausbreitenden Explosionen verwendet, wodurch eine Flammenstrahlzündung und Vorkompressionseffekte in angeschlossenen geschützten Behältern verhindert wird. Er reduziert das Risiko einer Flammenübertragung.
Diese Europäische Norm beschreibt die grundlegende konstruktive Ausführung eines Rohr in Rohr Explosions¬schlotes, und sie legt die Prüfanforderungen und die Anwendbarkeit von Explosions-schloten fest.
In dieser Norm sind festgelegt:
-   ein Prüfverfahren zur Bewertung der Wirksamkeit von Explosionsschloten;
-   Konstruktionsvorschriften für einen Typ eines Rohr in Rohr Explosionsschlotes;
-   Anforderungen an die Druckentlastungseinrichtung auf dem Explosionsschlot;
-   Installationsanforderungen;
-   Wartungsanforderungen;
-   Kennzeichnung.
Diese Europäische Norm gilt nur für explosionsfähige Staub/Luft Gemische.

Dispositifs déviateurs d'explosion

Un déviateur d'explosion est utilisé pour dévier des explosions qui se propagent dans des canalisations,
empêchant ainsi l'inflammation par jet de flamme et la pré-compression dans les enceintes protégées et
reliées. Il diminue le risque de transmission de la flamme.
La présente Norme européenne décrit la conception de base d'un dispositif déviateur à tuyau interne et
spécifie les exigences d'essai ainsi que l'application des dispositifs déviateurs d'explosion.
La présente Norme Européenne traite :
⎯ d’une méthode d'essai destinée à évaluer l'efficacité des dispositifs déviateurs d’explosion ;
⎯ des règles de conception d'un type de déviateur à tuyau interne ;
⎯ des exigences relatives au dispositif d‘évent situé sur le déviateur ;
⎯ des exigences d'installation ;
⎯ des exigences de maintenance ;
⎯ du marquage.
La présente Norme européenne ne prend en compte que les atmosphères explosives dues à des mélanges
poussière/air.

Preusmerjevalniki eksplozij

Preusmerjevalnik eksplozij se uporablja za preusmerjanje eksplozij, ki se širijo prek kablov. Naprava se uporablja za preprečevanje vžiga plamena in kopičenje tlaka v povezavi z zaščitenimi ohišji, če je pravilno načrtovana. Ta standard določa osnovne zahteve za načrtovanje in uporabo preusmerjevalnikov eksplozij. Ta standard določa metode za ocenjevanje učinkovitosti preusmerjevalnikov eksplozij in trenutna merila za njeno povečanje. Treba je opozoriti, da se preusmerjevalnik eksplozij ne more uporabljati kot naprava za izolacijo eksplozije, saj prenosa plamena ni mogoče učinkovito preprečiti. Ta standard obravnava le preusmerjanje eksplozij, ki se širijo na vnetljiv prašni zrak, zrak s plinom (hlapi), mešanice zrak-meglica ali njihove hibride.
