The utility model relates to a self-compensation type pipe joint which comprises a first joint piece and a second joint piece, wherein, the first joint piece and the second joint piece are respectively arranged on the end parts of two pre-connecting pipes; the docking head face of the first joint piece is provided with an annular concave part; a position of the docking head face of the second joint piece corresponding to the annular concave part is provided with an annular convex part which can be extended into the annular concave part; and an elastic sealing piece and a connecting piece are arranged between the annular concave part and the annular convex part, and the connecting piece is used for limiting the position between the first joint piece and the second joint piece. Because the elastic sealing piece can realize the sealing under a bending state, the pipe joint utilizes the automatic expansion of the elastic sealing piece to complete axial compensation, and so a pipeline connecting by the pipe joints can not be affected by expansion and contraction.
