Circumferential Seal Application: Military Aircraft
The control valve in a military aircraft had a controlled gap circumferential seal with a carbon steel composite ring assembly. High wear and carbon ring deterioration resulted in shortened seal life.
High temperature (1,125°F)
Pressure (660 psid)
Determining Cause and Failure Modes
High-temperature carbon grade oxidizing due to high temperature
Technetics Qualiseal Technologies Solution
Designed a controlled gap circumferential seal utilizing a solid silicon carbide ring, improving temperature rating up to 2,500°F
Silicon carbide ring increased seal pressure rating based on FEA generated stress distribution
