ABSTRACT:
A flange aligning device including an elongated body having a transverse internally threaded passage at each end and a carriage which can be moved along the body. A jacking screw is threaded into each of the internally threaded passages so that the distance between each end of the body and a pipe section which that end confronts can be determined by rotating one of the jacking screws. A tie plate is bolted to the carriage and is provided with elongated holes for receiving studs which pass through preexisting holes in the flange of one of the pipe sections. Different tie plates are provided to accommodate different pipe diameters, flanges, etc., each of which tie plates can be mounted on the carriage by means of bolts and associated tapped holes.
