Inlet Air Piping - Ingersoll-Rand CENTAC Instruction Manual

SECTION 1 PLANNING & INSTALLATION
Summarizing, a satisfactory piping arrangement can normally be obtained by giving proper
attention to:
1. Providing adequate support for all parts of the piping system.
2. Allowing for expansion in a manner that will avoid piping strains on the compressor.
3. Installing a sufficient number of anchors in the piping system so that direction and
magnitude of expansion are controlled.
4. Designing the inlet and discharge piping so as to provide smooth flow with minimum
pressure drop and uniform velocity over the entire area of piping.
The design of the piping system is the responsibility of the customer. Data and
comments are offered as an aid to ensure a successful installation, but
Ingersoll-Rand cannot assume responsibility for its design or installation. We
recommend that the customer consult a specialist skilled in the design of piping
systems to supplement and interpret the piping information and to ensure a
successful installation.
The inlet pipe and filter must be inspected before startup by an Ingersoll-Rand
factory certified service representative.
All air and water piping to and from the inlet and discharge port connections must
take into account vibration, pulsations, temperature, maximum pressure applied,
corrosion, and chemical resistance. Where compatibility questions may exist,
contact your Ingersoll-Rand representative.

Inlet Air Piping

Inlet air is the lifeline of any compressor. It is imperative that the compressor receives clean
filtered air to function correctly with low maintenance. A well thought out piping design will
save many hours and dollars in maintenance.
Whether the inlet air piping is supplied with the compressor or by others it must be inspected
for cleanliness by an Ingersoll-Rand factory certified service technician prior to start-up.
Maintenance
It is advisable that you install spool pieces that allow the casing sections to be removed and
the piping to be out of the way of personnel for maintenance. The inlet pipe will be removed
for inspection at start-up.
The importance of always operating the compressor with clean air inlet piping must be
stressed. No compressor will accept the injection of foreign material into the operating
components without possible damage or loss of performance.
