Pack-Off Flange for Oilfield

 

Destination:

Pack-off flanges are usually used as a cross-over connection to adapt flanges of different pressure ratings or sizes and provide an extra safety seal of the casing.

There are pack-off flanges provided with one seal, recommended for pressures up to 5,000 PSI (350 bar) and pack-off flanges with two seals, recommended for pressures up to 15,000 PSI (1050 bar).

 

The type of Pack-off flange depends on the seal used in it.
