DonadonSDD propose des disques de rupture LPD qui sont con\u00e7us pour prot\u00e9ger les installations industrielles contre les variations de pression tr\u00e8s faibles qui peuvent causer de graves dommages. Les disques de rupture LPD sont constitu\u00e9s de 3 composants ou plus qui forment un disque unique pouvant \u00eatre install\u00e9 directement entre des brides ou dans des supports (en fonction de l’application sp\u00e9cifique) ; ils sont dot\u00e9s d’une lame de couteau qui freine la couche de PTFE en cas de contact. <\/p>\n

Caract\u00e9ristiques et avantages techniques<\/h2>\n

Normes de certification \u00e9lev\u00e9es :<\/span><\/h3>\n

Nos disques de rupture LPD sont certifi\u00e9s conformes aux normes internationales les plus strictes, notamment <\/span>ATEX EX II 2 GD (CACHET CE), <\/span>PER 2016 UK Statutory Instruments 2016 No 1105 (UKCA STAMP), et CU TR 032 (EAC STAMP).<\/span><\/p>\n

Technique :<\/span><\/h3>\n

Compos\u00e9 d’une partie m\u00e9tallique perfor\u00e9e et fendue, d’une membrane d’\u00e9tanch\u00e9it\u00e9 (g\u00e9n\u00e9ralement en PTFE), d’une section de protection et d’un anneau de calibrage avec des lames pour am\u00e9liorer la rupture de la membrane.<\/span><\/p>\n

Applications :<\/span><\/h3>\n

Con\u00e7u pour les applications n\u00e9cessitant une protection \u00e0 tr\u00e8s basse pression (positive ou n\u00e9gative). Id\u00e9al pour prot\u00e9ger les r\u00e9servoirs de traitement et de stockage, les cuves atmosph\u00e9riques et les silos \u00e0 faible pression de conception contre l’implosion ou la rupture. <\/span><\/p>\n

Caract\u00e9ristiques :<\/span><\/h3>\n

Peut \u00eatre personnalis\u00e9 pour r\u00e9pondre \u00e0 un large \u00e9ventail de sp\u00e9cifications et d’applications non standard.<\/span><\/p>\n

R\u00e9sistance au vide :<\/span><\/h3>\n

Un support sp\u00e9cifique pour la protection contre le vide et la contre-pression est disponible sur demande. <\/span><\/p>\n

Option de disque \u00e0 double sens :<\/span><\/h3>\n

Prot\u00e8ge simultan\u00e9ment contre le vide et la pression (m\u00eame avec deux pressions diff\u00e9rentes).<\/span><\/p>\n
