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.

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
 Axial : Parallel to the pipe run (Longitudinal axis)

Lateral : Perpendicular to both the vertical and the
axial axes. ( Transverse axis)
