特徴とするライニング管端面のフレア部構造。 In a lined pipe having a sleeve lining in which a sleeve-shaped lining material is fitted inside the pipe and is in close contact with the inner wall of the pipe, the sleeve lining extends outward from the end face of the pipe for a required length in the axial direction of the pipe. A flared portion formed by bending and forming a flange-like shape having a predetermined outer diameter along the end surface has a wall thickness variation that is thicker at the bent portion and decreases in thickness toward the outer edge of the flared portion at the inner edge of the tube end surface. The amount of scraping that is greater than or equal to the difference in the thickness of the uneven wall thickness and that becomes zero at the location where the outer edge of the flare portion is located is absorbed by the slope surface formed on the tube end surface, and the flare is absorbed by the slope formed on the tube end surface. A flared part structure of an end face of a lining pipe, characterized in that the end face of the part is formed parallel to a plane perpendicular to the pipe axis of the lining pipe.
