<p>PROBLEM TO BE SOLVED: To provide a method for lining a tube capable of lining smoothly and surely. SOLUTION: The method for lining the tube comprises the steps of superposing a plurality of elastic tubes laminated double or more each made of a synthetic resin, a rubber or the like, forming the tubes in a cylindrical state, forming a lining material by coating an outer peripheral surface of the tube with a resin absorbing material of a woven fabric or a nonwoven fabric, drawing a curable resin into a duct while impregnating the absorbing material of the lining material with the resin, expanding the tube by filling a pressured fluid, curing the curable resin, and then drawing the tube. The method for lining the tube by pressure inverting comprises the steps of forming the lining material by coating a surface of the resin absorbing material of the woven fabric or the nonwoven fabric with a plurality of the elastic tubes laminated double or more each made of the synthetic resin rubber or the like, pressure inverting the lining material in the duct, and then lining the tube.</p> |
