Introduction
Pipe: Pipe can be defined as pressure tight cylinder used toconvey fluids.
Piping: Pipe sections when connected with fitting ,valvesand other mechanical equipment/component and
properly supported by hangers and supports
called piping.

Piping Arrangements
Purpose: Piping cost form a significant portion of a plant s total
investments, the constructions , operation and maintenance
provisions that will optimize these cost are an important aspect in
design process.

Piping Arrangements
General Routing Criteria:There are some criteria that
optimize piping cost and proper functioning of system.
Piping from source to destination should be as short aspossible with minimum change in direction.
Piping should not hinder any normal passage way also shouldnot encroach any equipment maintenance space.
Preferable
Not Preferable

General Routing Criteria
Valves ,strainer, instruments on pipe should be easily accessible if
needed provide separate access platform.
Specific requirements of straight length of pipe for some
components to be maintained ,like for flow orifice we need to
provide 15 D straight pipe length at up stream of orifice and 5Dpipe at down steam of orifice.
Example of Straight length requirement for Flow Orifice

General Routing Criteria
For pipe line which shall carry liquid we have to make sure
that all filled air allowed to vent out of the line when line is filled
to achieve this a vent connection is provided on top most point
of pipe line.
Also arrangement is kept in the pipe line so that liquid can be
drain out if required.

General Routing Criteria
To avoid air pockets inpump suction line use
top flat eccentric
reducer that will
prevents chances of
air pockets formations.

General Routing Criteria Check feasibility for installation of pipe supports and make full
utilization of existing structural and concrete.
Preferably use long radius elbows where elbow are required
