Adapter Flangers and Packoff Flangers
The packoff flange is a studded flange linking two spools.
The packoff flange may have the same size and pressure of the top and bottom flanges or it may be an adapter flange passing from one value of size and pressure to another one. The packoff flange may include a BREDA or PP – type secondary seal.
Data to be put down in the inquiry:
- size and rated pressure of the bottom flange and top flange
- secondary seal size and type
- temperature and service conditions
- PSL and PR levels.
