Abstract:
    The inventive structure comprises a first tube joint, a second tube joint with a larger expansion coefficient sleeved outside the first tube joint and an intermediate tube, whose inner surface is connected with the outer surface of the first tube. The inventive connecting method includes the following steps: sleeving the intermediate tube outside the first tube joint and realizing a seal connection and sleeving the second tube joint outside the intermediate tube and realizing a seal connection, so as to realize a seal connection between the first and second tubes. The first tube can be a metal tube and the second tube can be a glass fiber reinforced plastic tube.
