Plan 22Single Seals
General: If the seal is set up with a distributed or extended flush, the effectiveness of the system will be improved. This plan should be equipped with a differential pressure indicator or alarm to alert the user that the filter or strainer is clogged.
Advantages: No product contamination, and solids are removed from the flush stream keeping the seal clean.
Plan 51Single Seals, Quench
Description: Plan 51 external reservoir providing a dead-ended blanket of fluid to the quench connection of the gland. Typically used with an auxiliary sealing device.
Advantages: Can be used to retard/prevent cyrstallisation or icing on atmospheric side of seal
General: Careful selection of auxilliary sealing device required to prevent escape of blanket fluid from reservoir.
May not be possible to achieve a 3-year operating life dependant on type of auxillary sealing device used.
Plan 61Quench Seals
Description: Tapped connections for purchaser’s use. Typically this plan is used when the purchaser may use a quench in the future.
Advantages: None.
General: None.
Plan 71Secondary Containment Seals
Description: Tapped connections for purchaser's use. Typically this plan is used when the purchaser may use buffer gas in the future.
Disadvantages: Plan 22 should be used with caution as strainers can clog and result in seal failure.
Note: ANSI/API 682 3rd edition comments “this plan has not been proven to achieve a 3-year operating life”.
