GS 74 Steam
Global Standardized Pressurized Steam Supply Panel
The GS 74 - Steam global standardized system is an optimized, pre-engineered design based on John Crane’s fluid control expertise and engineering excellence. The GS 74 - Steam is a best-practice solution that significantly reduces specification review and delivery schedules and delivers pressurized barrier steam for optimal mechanical seal performance and reliability.
The GS Plan 74 - Steam supports a dual pressurized non contacting gas seal by conditioning and controlling the continuous supply of pressurized dry steam. It features an upstream and downstream panel including a condensate separator, pressure regulator, check valve, steam traps, and instrumentation to monitor the pressure in the panel. This product performs a similar function to the Plan 74 piping plan as defined in API 682 4th Edition, modified to operate with steam as the barrier fluid instead of nitrogen or argon. The GS 74 - Steam is designed to support non-contacting mechanical seals meeting the specification of API 682 4th Edition.
This product has been specifically designed to provide the ideal support environment for the 2874HTC non-contacting metal bellows seal.
For non contacting seals requiring a pressurized barrier gas other than steam, see the GS 74.
