No Slide TitleINTRODUCTION SUPPORT A (pipe work) device for retaining a pipe and its ancillaries in a specifically designed position. Page * ANCHOR: A special supporting device for restraining pipes in position and direction to permit the control of pipe movement which occurs due to thermal expansion. CLEVIS PIPE CLAMP: CONSTANT LOAD SUPPORT: A spring loaded support designed to enable the load on the pipe to be constant and balanced regardless of the vertical movement that may take place. GUIDE: A device for ensuring a pipe is restrained from moving in a direction (or) plane other than that warranted by ideal design conditions. Page * HANGER: A method of supporting pipe work from a structure above, usually maintaining the pipe work at a designed level but allowing limited axial and sometimes, lateral movement. RESTRAINT: A (pipe work) supporting device that partially (or) totally restricts movement in one (or) more directions. ROLLER SUPPORT: A roller, on which the pipe rests, permitting axial movement in a horizontal plane. Page * SLIDER SUPPORT: A special pipe support designed to permit longitudinal movement of the pipe work in a horizontal plane. SPRING HANGER: A pipe support designed to counteract differing positions as a result of the varying conditions to which the piping is subjected. Page * STANCHION: A structural steel member whose main function is to withstand axial compressive stresses. TRESTLE: A structural steel frame usually designed to carry a bank of pipes above ground level. TRUNNION: A tubular piece of steel welded to the side of a pipe to enable the latter to be supported. Page * TURN BUCKLE: A device for providing axial adjustment for pipe hanger rods – adjustment is achieved by the turn buckle having right and left handed threads. SHOE: A metal piece attached to the under side of a pipe which rests on supporting steel. Primarily used to reduce wear from sliding for lines subject to movement. Permits insulation to be applied to pipe. Page * Look for availability of beams/columns in the vicinity for supporting Vertically hung or bottom support – based on availability of support beams Use applicable codes and standards Use vendor catalogues PIPING ENGINEERING – SUPPORTS The suggested maximum span between the supports ,as recommended by ASME B 31.1 in Table 121.5, are as follows.
