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.

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.
