Malleable cast iron fittings with compression ends for steel pipes
This standard specifies the requirements for the design, performance and testing of fittings made of malleable cast iron (see also clause 5 Materials) with compression ends for steel pipes. It applies to steel piping systems for different application fields, such as gas supply, distribution of water for general purposes and for human consumption, irrigation, fire fighting, aqueous liquids, compressed air and gaseous fuel systems.
It also applies to oil piping systems, provided the elastomeric sealing material is compatible with the oil and the operating conditions.
It contains requirements and tests relating to compression fittings which can be disconnected from smooth walled steel pipes or other cylindrical metal structural elements, which are applicable for dismantleable joints. The fittings can also incorporate other types of connection, such as threaded, flanged, compression ends for connection of polyethylene pipes, etc., and can also take on various structural shapes, such as, straight piece, elbow or T-piece, etc. Their range of sizes covers nominal sizes DN 6 to DN 100 (size 1/8 to 4).
Tempergussfittings mit Klemmanschlüssen für Stahlrohre
Diese Norm legt die Anforderungen an die Konstruktion, Anwendungsmerkmale und Prüfung von Tempergussfittings mit Klemmanschlüssen für Stahlrohre fest. Sie gilt für Rohrleitungssysteme aus Stahl für unterschiedliche Anwendungsbereiche, z. B. Gasversorgung, Wasserverteilung für allgemeine Zwecke sowie für Trinkwasser, Bewässerung, Löschwassersysteme, wässrige Lösungen, Druckluft und gasförmige Brennstoffe.
Diese Norm gilt ebenfalls für Rohrleitungen für Öl, sofern die Elastomer-Abdichtungen mit dem Öl und den Betriebsbedingungen kompatibel sind.
Die Norm enthält Anforderungen und Prüfungen für Klemmanschlüsse, die von glattwandigen Stahlrohren oder anderen zylindrischen Bauteilen aus Metall (im folgenden kurz „glatte Rohrverbindungen“ genannt)
demontiert werden können. Die Fittings können auch andere Verbindungsarten umfassen, z. B. Gewinde-, Flansch- und Klemmverbindungen für Rohre aus Polyethylen usw. und in unterschiedlichen Formen ausgeführt sein, z. B. als gerade Anschlüsse, Bogen oder T-Stücke, usw. Der Nennweitenbereich umfasst die Nennweiten DN 6 bis DN 100 (Größe ⅛ bis 4).
Raccords à compression en fonte malléable pour tubes d'acier
La présente norme spécifie les exigences de conception, de performances et d’essai des raccords à compression en fonte malléable pour tubes en acier. Elle s’applique aux réseaux de canalisations en acier utilisés dans des différents champs d’application, tels que l’alimentation en gaz, la distribution d’eau destinée à des usages généraux et à la consommation humaine, l’irrigation, la lutte contre l’incendie, les liquides aqueux, les systèmes à air comprimé et à combustibles gazeux.
La présente norme s’applique également aux réseaux de canalisations d'hydrocarbures, à la condition que le produit d’étanchéité élastomère soit compatible avec l’huile et les conditions de fonctionnement.
Elle spécifie des exigences et des essais relatifs aux raccords à compression pouvant être démontés à partir de tubes lisses en acier ou d’autres éléments structurels cylindriques en métal, utilisables pour les joints démontables. Les raccords peuvent également comporter d’autres types de connexions, telles que les extrémités de compression filetées ou à bride, utilisées pour des tubes en polyéthylène, entre autres. Ils peuvent aussi se présenter sous différentes formes : raccords droits, coudes ou tés. Leur gamme de dimensions comprend les dimensions nominales DN 6 à DN 100 (dimension 1/8 à 4).
