DESIGN CRITERIA

The major criteria governing support hardware selection are support function, magnitude of expected load ,and space limitations.The following points should also be kept in mind:

1)The design temperature of the piping system used for selection of pipe clamps , u bolts, straps and other steel in direct contact with pipe .The strength of these items decline with increase in temperature .

2) Piping operation at high temperature or subject to condensation on the outer surface will usually be insulated.The pipe support hardware must be designed to accommodate the insulation.

3)The piping attachment and supporting structure in contact with each other must be of compatible material in order to reduce galvanic action.

4)The inspection of the hardware of supports to be done at start-up and also periodic inspection is required.

PIPE SUPPORTS

SUPPORT TERMINOLOGY Supports (or restraints ) are usually classified

according to both, direction and function.The major direction of restraints are those conforming to the three local axes of the pipe .

Vertical : Gravity, Self Weight Axial : Parallel to the pipe run (Longitudinal axis) Lateral : Perpendicular to both the vertical and the axial axes. ( Transverse axis)
