Abstract
An apparatus and method for re-rounding a distorted end (e.g., oval-shaped) of a pipe for insertion into a mechanical joint fitting or pipe bell have a circular diameter. The apparatus involves two separate semi-circular members having jack bolt assemblies evenly distributed in each. The two ends of each of the semi-circular members have extensions that can be releasably coupled to join to the two members to form a circular re-rounding tool. A first semi-circular member is positioned on the maximum diameter side of the distorted pipe and the other semi-circular member is placed on the opposite side of the distorted pipe and extensions joined. With an equal number of jack bolt assemblies in each member, corresponding jack bolt assemblies in the two members are diametrically aligned forming pairs. To re-round the distorted end, pairs of these jack bolt assemblies are tightened in a “star sequence” to re-round the distorted end. The re-rounded end is inserted into the mechanical joint fitting or pipe bell and the extensions are decoupled to easily remove the circular tool from the re-rounded end.
