ABSTRACT:
An expansion joint which employs a flexible material to connect and inlet duct equipment to an outlet duct or equipment includes an inlet frame which is connected to the inlet duct and an outlet frame which is connected to the outlet duct. In a hot frame to cold frame type of expansion joint, the inlet frame, along with an inlet liner is shaped to form a channel which has at least one side which is acutely angled with respect to the primary direction of gas flow through the expansion joint. Expansion joints for use in a cold frame to hot frame and in a hot frame to hot frame application are also described. The expansion joint additionally employs clamps, which clamp the flexible material to the inlet and outlet frames in a manner which reduces the amount of heat to which the flexible material is exposed.
