Abstract
En fremgangsmåte for sentralisering av rør før. sementering og etterfølgende ekspansjon involverer bruk av en flerhet av teleskoperende sylindere hvis fremre eller bakre ende er lukket, og som føres frem av påført innvendig trykk i røret eller mekaniske midler. Røret ekspanderes fra sitt indre med de sylindriske teleskoperende elementer fremdeles ført frem. Sementen skyves på grunn av sentraliseirngsenhetene helt rundt røret. Etter at sementen er levert skyver ekspansjonen av røret de teleskoperende elementer inn i borehullets vegg.
