PROCEDE ET MOYEN DE SOUDAGE DE TUBES EN MATIERES PLASTIQUES POLYMERES

摘要

A sleeve for coupling two plastic polymeric tubes whose diameter enables them to be adjustably positioned in the tubes. At least part of the sleeve is made of an electrically conductive polymer or a polymer containing a conductive filler An Independent claim is included for coupling two polymeric tubes using a sleeve as above. Preferred Features: The conductive part of the sleeve includes the parts contacting the ends of the tubes. Points for connecting an electrical supply to the sleeve for heating the sleeve are arranged equidistantly around at least one circumference of the sleeve.
