Flanse intermediare
Предназначение:
Flansele intermediare sunt folosite in mod obisnuit pentru a realiza adaptarea si legatura dintre flanse de diferite marimi si presiuni, asigurand o etansare suplimentara a burlanului.
Exista flanse intermediare prevazute cu o singura etansare, recomandate pentru presiuni de pana la 5,000 PSI (350 bar) si flanse cu doua etansari, recomandate pentru presiuni de pana la 15,000 PSI (1050 bar).
Данные о классе материала и классификации температур смотрите в Приложении А.
Tipul flansei intermediare este determinat de etansarea folosita.
