ABSTRACT:
An improved rotating pipe joint for use in the sootblower system of a rotary regenerative air heater employs a ball and socket type construction floating seal assembly. The ball and its associated seal rings rotates within the socket to allow a slide pipe of the sootblower system to deviate from the vertical position while maintaining sealing. The improved rotating pipe joint also accommodates rotary, axial and lateral motion between the moving and stationary parts of the air heater.
