Seal and insulator for pipe having an insulated electrical conductor

A structure for pipe segments having an insulated electrical conductor, comprising:

• a first electrical contact disposed at one end of an insulated electrical conductor extending on an interior of a first pipe segment from a male threaded connection on one longitudinal end of the first pipe segment to a female threaded connection on another longitudinal end of the first pipe segment;
• a second electrical contact disposed on the other end of the insulated electrical conductor, the first electrical contact shaped to make electrical connection with a corresponding second electrical contact in a second, adjacent pipe segment having a first electrical contact, an insulated electrical conductor, the corresponding second electrical contact, a male threaded connection and a female threaded connection, when the male threaded connection on the first pipe segment is engaged to the female threaded connection on the second pipe segment;
• a seal disposed on an interior of an insulating layer on an interior wall of each of the first and second pipe segments, a space provided beyond a longitudinal end of the seal between at least one of the first and second electrical contacts and the insulating layer, wherein the space enables radial inward flexure of the seal under pressure such that thread lubricant extruded by connecting the male threaded end of the first pipe segment to the female threaded end of the second pipe segment is pressure relieved.
