摘要: An expansion joint device (10) used for metal conduits comprises an inlet short tube (1), an outlet short tube (2), and a sleeve (3). Both the opposed inside ends of the two short tubes (1, 2) are in the inside of the sleeve (3) and form a compensating gap (6) between them. A bellows member (7), axially expansible with an external force applying on, is provided in the compensating gap (6) formed between the opposed inside ends of the two short tubes (1, 2). The two ends of the bellows member (7) are respectively connected with the inside ends of the two short tubes (1, 2) in sealed manner. At least one of the two ends of said sleeve (3) is free end with respect to the two short tubes (1, 2).
