This document provides guidelines for supporting piping systems that use flexible grooved couplings. It discusses the differences between supporting rigid versus flexible coupling systems. For flexible systems that allow movement, it recommends maximum hanger spacing distances between supports for various pipe sizes and whether full linear movement is or is not required. No pipe section should be left unsupported between any two couplings. Supports should be attached to adjoining pipes and equipment only, not directly to the couplings.

26.01 PIPE SUPPORT FLEXIBLE COUPLINGS – RIGID COUPLINGS Piping joined with grooved type couplings, like all other piping systems, requires support to carry the weight of pipes, equipment and fluid. Like all other methods of joining pipes, the support or hanging method must be such as to eliminate undue stresses on joints, piping and other components. Additionally, the method of support must be such as to allow movement of the pipes where required and to provide for other special requirements such as drainage, etc. as may be required by the designer. The support system for flexible mechanical grooved type pipe couplings must consider some of the special requirements of these couplings. The tables show suggested maximum span between pipe supports for horizontal straight runs of standard weight steel pipe carrying water or similarly dense liquids. They are not intended to be used as specifications for all installations. These DO NOT apply where critical calculations are made or where there are concentrated loads between supports. Do not attach supports directly to the couplings. Support adjoining pipe and equipment only. RIGID SYSTEMS For Victaulic rigid coupling Styles 07, W07, 307, HP-70, 005, 009, and others, the Maximum Hanger Spacing below may be used. FLEXIBLE SYSTEMS For coupling Styles including 75, 77, W77, 770, and others. Standard grooved-type couplings allow angular, linear and rotational movement at each joint, to accommodate expansion, contraction, settling, vibration, noise and other piping system movement. These features provide advantages in designing piping systems but must be considered when determining hanger and support bracing and location. Maximum Hanger Spacing For straight runs without concentrated loads and where full linear movement is required.
