ABSTRACT:
A remote pipe fitting tool for adjustably positioning the ends of relatively small pipes while being tack welded. The tool includes clamps engaging adjacent pipe ends with each of the clamps including laterally extending arms which are interconnected at their outer ends by a plurality of spaced turnbuckles with a pair of outermost turnbuckles and an inner turnbuckle adjusting various relationships between the pipe ends. Each of the arms includes means to longitudinally adjust the length thereof to move the adjacent pipe ends transversely in relation to each other. Also, each arm includes a jack bolt and pivot structure enabling the clamps and thus the pipe ends to be angularly adjusted. The remote pipe tool enables adjacent pipe ends to be joined to be universally adjusted in relation to each other in an accurate, positive, quick and easy manner thereby greatly facilitating the positioning of pipe ends when being joined by welding.
