All over the world, industries that operate in the chemical, petroleum,
Sanitary or agri-food industries use facilities of several types
Equipment such as tanks, condenser, turbine, exchangers, mixers, filters,
Pumps and so on.
Piping is an industrial system that provides fluid bonding and flows (gas,
Liquid, powder, etc.) between these installations, it may consist of tubular elements
(Pipes), connecting elements (flanges, tees, elbows, etc.), and various apparatus ensuring the
Regulation and control of the pressure, flow, and temperature of the transmitted fluid (valves,
Valve …) (see figure below)
Figure 19: Piping network
Piping forms a three-dimensional structure in space which, during its
Period of operation is subject to a number of internal demands
(Pressure, temperature, …) or external (gravity, wind, earthquake …) which generate
Stresses and deformations; These can be introduced initially, by the manufacture
And mounting, or appearing as a result of various circumstances, during the tests,
Operation or shutdown.
In the study of piping, the following stresses must be taken into account:
Internal or external pressure.
The effect of gravity.
Climatic stresses (the wind, snow).
Movements of soil and buildings (earthquake, settlement).
Changes in temperature (expansion or contraction).
The vibrations … etc.
Support: It is a device designed to:
To support the weight of the piping as well as that of all the equipment which are
Orient and report the effects of piping stress on
The environment and on itself: and in general, remove or limit one to
Six degrees of freedom from a particular point in the piping.
Pipe supports must meet the following objectives:
Low cost in studies.
Low cost and reduced manufacturing time.
Ease of assembly.
High reliability in service.
The support types.
