ABSTRACT:
A method of making a rotationally symmetric pipe pig in which porous abrasive material is adhered to the periphery of the pipe pig. A liquid applied surface layer of the pig body forms an adhesive for the porous abrasive material, which is cured after the application of the porous abrasive material. A porous abrasive material is alumina ceramic beads. The pipe pig thus formed has a porous abrasive material adhered to the periphery of the pipe pig.
