Atmospheric Side
Filter Plan Types
API Plan 51
External reservoir providing a dead-ended fluid blanket to the quench connection.
API Plan 61
Tapped and plugged atmospheric-side connections for the purchaser’s use.
API Plan 62
Quench stream is brought from an external source to the atmospheric side of the seal.
API Plan 65A
Atmospheric leakage collection and detection system for condensing leakage. Seal failure is detected by an excessive flow rate into the leakage collection system.
API Plan 65B
Atmospheric leakage collection and detection system for condensing leakage. Seal failure is detected by cumulative leakage into the leakage collection system.
API Plan 66A
Throttle bushings in the seal gland minimize the leakage leaving the seal gland and allows for detection of a seal failure.
API Plan 66B
An orifice plug in the drain port minimizes the seal leakage leaving the seal gland and allows for detection of a seal failure.
API Plan 75
Leakage collection system for condensing or mixed phase leakage with a contacting containment seal.
