Title | Raccords à compression en fonte malléable pour tubes en acier |
Work Item Number | EC110271 |
Abstract/Scope | Le présent document spécifie les exigences relatives à la conception, aux performances et aux essais des raccords en fonte malléable (voir également l'Article 5, Matériaux) avec extrémités à compression pour les tubes en acier. Le présent document s'applique aux systèmes de canalisation en acier utilisables dans différents domaines, comme l'alimentation et la distribution en gaz, l’eau à des fins générales (par exemple l’irrigation), ainsi que pour la consommation humaine, les liquides aqueux et l'air sous pression. Le présent document contient des exigences et des essais relatifs aux raccords à compression qui peuvent être raccordés à des tubes en acier à paroi lisse. Les raccords peuvent également inclure d'autres types de raccordements, tels que des extrémités filetées conformes à l'EN 10226-1, des extrémités à brides, des extrémités à compression pour les tubes autres qu'en acier et ils peuvent également prendre différentes formes de structure, telles que la pièce d’adaptateur droite, le coude ou la pièce en T. Leur gamme de dimensions couvre les dimensions nominales DN 10 à DN 100 (dimension des raccords 3/8 à 4). |
