Flanges and their joints - Circular flanges for pipes, valves, fittings and accessories, PN designated - Part 1: Steel flanges

This European Standard for a single series of flanges specifies requirements for circular steel flanges in PN designations PN 2,5 to PN 400 and nominal sizes from DN 10 to DN 4000.
This European Standard specifies the flange types and their facings, dimensions, tolerances, threading, bolt sizes, flange jointing face surface finish, marking, materials, pressure/ temperature ratings and approximate flange masses.
For the purpose of this European Standard, "flanges" include also lapped ends and collars.
This European Standard applies to flanges manufactured in accordance with the methods described in Table 1.
Non-gasketed pipe joints are outside the scope of this European Standard.

Brides et leurs assemblages - Brides circulaires pour tubes, appareils de robinetterie, raccords et accessoires, désignées PN - Partie 1: Brides en acier

La présente Norme européenne pour un seul système de brides spécifie les prescriptions pour les brides circulaires en acier avec les désignations PN 2,5 à PN 400 et les diamètres nominaux DN 10 à DN 4000.
La présente Norme européenne définit les types de brides et leurs portées de joint, les dimensions, les tolérances, les filetages, les dimensions des boulons, les états de surface des faces de joints des brides, le marquage, les matériaux, les relations pression/température et les masses approximatives des brides.
Pour les besoins de la présente Norme européenne, le terme « brides » inclut aussi les collets et les extrémités embouties à souder.
La présente Norme européenne s'applique aux brides fabriquées selon les méthodes décrites au
Tableau 1.
Les assemblages de tuyauteries sans joints se trouvent hors du domaine d'application de la présente Norme européenne.

Prirobnice in prirobnični spoji - Okrogle prirobnice za cevi, ventile, fitinge in pribor z oznako PN - 1. del: Jeklene prirobnice

Ta osnutek evropskega standarda za posamezni niz prirobnic določa zahteve za okrogle jeklene prirobnice z oznakami PN od PN 2,5 do PN 400 in nominalno velikostjo od DN 10 do DN 4000.
Ta osnutek evropskega standarda določa vrste prirobnic in njihove prevleke, mere, tolerance, navoje, velikosti vijakov, površinski premaz stične ploskve prirobnice, označevanje, materiale, vrednosti tlaka/temperature in približne mase prirobnic.
Za namene tega osnutka evropskega standarda »prirobnice« vključujejo tudi preklopljene konce in obroče.
Ta osnutek evropskega standarda velja za prirobnice, proizvedene v skladu z metodami, opisanimi v preglednici 1.
Spoji cevi brez tesnil ne spadajo v področje uporabe tega osnutka evropskega standarda.
