API Plan 51 Quench from Reservoir
API Plan 51 is a quench system for use on the atmospheric side of a single seal. This system acts as a dead-ended reservoir for a fluid. API Plan 51 Kit contents shown solid and include some optional components. This plan: Prevents icing on the atmospheric side of the seal Is typic...

API Plan 62 Quench from External Source
API Plan 62 delivers an external quench fluid to the atmospheric side of the seal. A typical application in a refinery is the prevention of coking on seal faces in hot hydrocarbon service by employing a steam quench. Nitrogen or clean water may also be used to quench or cool and clean the atmospheri...

API Plan 65A Leakage Collection with Reservoir
API Plan 65A monitors leakage in a single seal arrangement. Connected to the drain port on the gland, a reservoir collects normal leakage and is constantly open to drain. In the event of a seal failure, an orifice fitting on the outlet of the system allows a level transmitter to trigger an alarm due...

API Plan 65B Leakage Collection with Reservoir
API Plan 65B monitors leakage in a single seal arrangement. Connected to the drain port on the gland, a reservoir is allowed to collect normal leakage. A level transmitter on the reservoir triggers an alarm in the event of excessive leakage. A valve on the outlet side of the reservoir is typically l...

API Seal Plan 52 Buffer Fluid Seal Pot
< Back to Between Seal Plans API Seal Plan 52 utilizes a reservoir and circulates an unpressurized buffer fluid between the inboard and outboard seals. To provide positive circulation through the support system and into the seal, a pumping ring is employed. Frictional losses in the buffer fluid in...

API Plan 53A Barrier Fluid Seal Pot Pressurized by Nitrogen
API Plan 53A utilizes a reservoir and circulates a pressurized barrier fluid between the inboard and outboard seals. The typical source of pressurization is plant nitrogen. The reservoir should be set at least 20 psi (1.3 bar) above maximum seal chamber pressure. This is to ensure that leakage acros...

API Plan 75 Condensing Leakage Collection
< Back to Between Seal Plans API Plan 75 collects leakage from the inboard seal in applications where normal process fluid leakage can condense between the seals at ambient temperatures. In this arrangement, a reservoir is connected to the containment seal drain port on the gland. Condensed leakag...
-
API Plan 76 Noncondensing Leakage Collection
API Plan 76 collects leakage from the inboard seal in applications where normal process fluid leakage does not condense between the seals at ambient temperatures. In this piping plan, gaseous leakage from the inboard seal exits through the containment seal vent port in the gland. The orifice creates...
