Abstract

PURPOSE: To reinforce the interior wall of a piping in situ and thereby to prevent leakage, by forming a cylinder of cross-linked thermosetting resin closely fitted to the interior wall of a laid piping.
CONSTITUTION: A elastomeric tube 1 made of rubber, elastic plastic, or the like is covered with a resin layer 2 preformed in a cylinder shape. The tube 1 is contracted and inserted in a laid piping 3, thereafter pressurized air is fed into tube 1 so that the tube 1 expands and the resin layer 2 contact closely the interior wall of the piping 3. The resin is heated above its primary transistion temperature to set the resin cylinder closely fitted to the interior wall of the piping 3. The adhesion between the resin cylinder and the interior wall of the piping 3 is ensured by a primer which has been either applied on the surfaces θ treated resin cylinder or applied on the surface- treated (e.g. by horning) interior wall of the piping 3. When the elastomeric tube 1 is to be left in situ after work, an adhesive layer consisting of a primer is formed in advance between the resin cylinder and the tube 1.
