ABSTRACT:
An apparatus and process for increasing the concentric bearing load capabilities of the length of liner is disclosed. Overlapping ends of vertically aligned pipe lengths are joined by a coupling which provides aligned throughholes through the respective pipe ends. A cylindrical liner having a length substantially equal to co-lengths of an individual pipe member is positioned such that a series of throughholes passing through an approximate mid-length portion of the liner are positioned opposite to and aligned with the pipe coupling throughholes. Fasteners are then used to secure the two vertically aligned overlapping pipe ends to the interior liner pipe.
