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.
Méthode de fabrication d'un racleur de tuyauterie rotationnellement symétrique dans laquelle on fait adhérer un matériau abrasif poreux à la périphérie du racleur. Une couche superficielle du corps du racleur appliquée à l'état liquide forme un adhésif pour retenir le matériau abrasif poreux, ladite couche superficielle étant séchée et durcie après l'application du matériau abrasif poreux. Le matériau abrasif poreux peut être constitué de billes en céramique d'alumine. Le racleur de tuyauterie ainsi formé est doté d'un revêtement périphérique fait de matériau abrasif poreux.
