Echipamente la gura sondei | Flanse intermediare
Destinatie: 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).
Pentru clasele de temperatura si clasele de material, vezi Anexa A.
Tipul flansei intermediare este determinat de etansarea folosita.
