Abstract: The present invention is an economical and conveniently installed support for flanged piping where the individual lengths thereof are bolted together. It is intended for use on long, substantially horizontal, runs of piping where it is desired to eliminate stresses on unsupported flanged joints, and is especially useful where valves and other heavy fittings are located between lengths of piping. The support is bolted directly to the bottom arc of the flange, having holes therein which match the holes in the flanges, and is especially useful with piping having Class 125 AWWA flanges. The support has convenient adjustments to compensate for variations in the height between the level of the piping and that of the supporting structure.
