  • Patent number: 7367748
    Abstract: A method of installing a non metallic pipeline segment along with a tracer wire segment using a horizontal directional drilling process includes positioning a horizontal directional drilling machine in a selected position on one side of the obstacle. A drill bit is attached to an end of a flexible steel pipe. The flexible steel pipe engages and is driven by the horizontal directional drilling machine that forces the drill bit and the flexible pipe from the first side of the obstacle to a second side of the obstacle thereby drilling a bore underneath the obstacle. The drill bit is removed and a reamer is attached to the end of the flexible pipe. An end of a pipeline segment along with an end of a tracer wire segment having a high carbon steel core and a copper cladding with a high density polyethylene jacket is attached to the reamer.
