Abstract:
A pipe pulling lubrication apparatus includes a pipe anchor having an anchor body. The anchor body includes a first coupling feature near an anchor body proximal portion and a distal pipe coupling feature near an anchor body distal portion. The distal pipe coupling feature is configured to couple and position a replacement pipe exterior surface near an anchor body exterior surface. The lubrication apparatus further includes a lubrication system including a lubricant conduit extending within the anchor body from the distal pipe coupling feature toward an anchor body intermediate portion between the first coupling feature and the distal pipe coupling feature. The lubrication system includes a lubricant distributor having one or more lubricant passages extending from the lubricant conduit toward the anchor body exterior surface, the lubricant distributor is configured to deliver a lubricant to the replacement pipe exterior surface.
