摘要： PURPOSE: An automatic expansion joint pipe is provided to effectively absorb changes in length or position of pipes due to ground behavior or temperature variation. CONSTITUTION: An automatic expansion joint pipe comprises a pair of movable flange pipes(111,112), an inner pipe body, and an outer pipe cover. The movable flange pipes are coupled to two pipes. Both ends of the inner pipe body are inserted into the movable flange pipes, and the inner pipe body is pressed onto the inner surface of the movable flange pipes with O-rings(115) to implement airtight seal. The outer pipe cover covers ends of the movable flange pipes, is pressed onto the outer surface of the movable flange pipes with O-rings, and is coupled to the inner pipe body in order to prevent the separation of the movable flange pipes.
