Expander
During normal operation, the Spring and Teflon Expanders remain captive and compressed. Upon failure of the Shear Pins the Expanders will spread the two shear rings allowing the head of the Teflon Expander to slide on the Shear Ring face until equipment shutdown, preventing Coupling damage.
