ABSTRACT:
An electrically-insulated pipe coupling includes a first tubular metal body, a second tubular metal body which has a cylindrical section and which has molded onto it an electrically-insulating covering extending over the end of the body and a portion of the cylindrical section, a coupling member for securing the two metal bodies together at their respective ends and which is disposed over the juncture of the two metal bodies in such a manner that a portion of the electrically-insulating covering molded onto the second tubular body extends beyond the coupling member, and an electrically-insulating barrier extending outwardly from the cylindrical section of the second tubular body and disposed about the portion of the electrically insulating covering extending beyond the coupling member.
