<p>PURPOSE:To simultaneously cure a tube lining material by uniformly heating an entire length of the material. CONSTITUTION:A method for liming a tube has the steps of inverting, inserting a tube liming material 2 into a conduit 1 by hydraulic pressure, then heating the material 2 by a heating medium while pressing the material 2 to an inner wall of the conduit 1, and a curing thermosetting resin impregnated with the material 2, and comprises the steps of operating pneumatic pressure to an interior of the material 2 inverted and inserted into the conduit 1, and circulating warm water to an entire length of a bottom in the material 2. Further, the method comprises the step of heating the material 2 with warm water to cure the resin impregnated to the material 2. According to this, since the material 2 is uniformly heated in its longitudinal direction with the warm water circulated in the bottom, the resin impregnated to the material is simultaneously cured, and partial curing delay does not occur at the material 2.</p> |
