<p>PROBLEM TO BE SOLVED: To prevent the remaining of excess wall thickness on a specific part of a lining tube by laying the lining tube along an inner peripheral surface of a pipe, and thickening the wall of the lining tube corresponding to the abrasion amount caused by the transport fluid in the circumferential direction. SOLUTION: A lining tube 1 composed of soft rubber is formed into the cylindrical shape gradually increasing its wall thickness from an upper part toward a lower part, and an urethane rubber layer 2 having a color different from that of the lining tube 1 of uniform thickness, is adhered to an outer peripheral surface of the lining tube 1. An outer peripheral surface of the urethane rubber layer 2 is reinforced by a reinforcement sheet 3 for constraining the circumferential and axial deformation against the action of the external force from the inner and outer peripheral sides of the lining tube 1, and further the rubbing to a pipe inner surface of the lining tube 1 can be prevented.</p> |
