ABSTRACT:
An electrically insulating pipe coupling assembly for electrically isolating pipe sections to which an electric current is applied. The apparatus includes first and second extension members formed having an integral flange with a protruding annular sealing bead at one end and adapted for attachment to a section of pipe at the other end. An insulating sleeve having an insulating flange is mounted on the first extension member. A nonconductive spacer is positioned between the opposing integral flanges to receive the annular sealing beads, separating and electrically isolating the first and second extension members. A first coupling member is slidably mounted on the insulating sleeve, while a second coupling member is slidably mounted on the second extension member. The coupling members, when secured together, force the annular sealing beads into compressive contact with the nonconductive spacer.
