1. , a kind of insulation tile comprises upper and lower two part watt shells, and both buckling states form the tubular structure of a hollow down, it is characterized in that:

  • The thin end of described tubular structure one end is thick, and thin end has more than one outer ring groove, butt end that more than one interior annular groove is arranged, and described outer ring groove and interior annular groove are all coaxial with described tubular structure;

    Thereby form continuous outer convex-concave structure and continuous interior convex-concave structure respectively at thin end and butt end;

    The external diameter of the outer convex section of the thin end of described tubular structure and the internal diameter of interior annular groove form Spielpassung or transition fit, and the external diameter of internal diameter that the butt end of described tubular structure is projecting inward section and outer ring groove forms Spielpassung or transition fit;

    The axial length of inboard axial end is suitable to interior annular groove for the axial length of described thin end and described butt end axial end;

    Then when described insulation tile fastened continuously, connection in twos and preceding watt butt end and back watt thin end buckled each other;

    The axial length of the outer convex section of each of described thin end is respectively less than the axial length of annular groove in each section of described butt end correspondence, each axial length of projecting inward section of described butt end is respectively less than the axial length of each section outer ring groove of described thin end correspondence, and its residual quantity all is not less than corresponding described insulation tile and is buckled in the poor of the expand with heat and contract with cold amount of pipeline under the pipeline operating temperature in it.
