Product Description - PREVOST PPS Manuel Technique

GB
BACKGROUND
Today's companies are faced with the necessity to constantly develop,
expand and modify production methods. Coupled with increasingly
automated production technologies, this necessity makes large-scale,
easy-to-modify compressed air distribution systems a must.
System PPS is specially designed for building compressed air distribution
systems.
Its materials and assembly methods make it a flexible and scalable solution
that is compatible with all PREVOST systems and able to meet even the
most complex equipment problems.
Installation is quick, easy and requires no costly or complicated tools.
Once installed, the completed ringmain ensures a good seal, outstanding
mechanical strength and lasting efficiency.
CORROSION
The aluminium alloy pipes, baked e-coating finish and render System PPS
pipes and fittings completely resistant to internal and external corrosion and
damage and significantly extend their service life under normal conditions
of use.
IMPACT RESISTANCE
System PPS pipes and fittings are constructed of materials which offer
excellent resistance to internal pressure and external impacts, even violent
ones.
Exposed main pipes conveying compressed air must be installed at least 2.5
metres above the floor to protect them from any risk of impacts.
UV RAYS
Aluminium is not affected by UV rays, allowing it to be used inside as
well as outside.
FIRE RESISTANCE
Aluminium has excellent fire resistance properties. It does not burn or
spread flames. PPS system is certified B – s1, d0 according to standard
EN 13501-1 : Fire test to Building Material
SOURCES OF HEAT
The extremely tough aluminium system withstands temperatures of up
to 80°C.
See the effect of temperature on pressure on page 9.
FLOW RATE
Because of their low friction coefficient, wide inner sections and the absence
of obstacles or narrow passages, PPS fittings offer excellent flow rates.

PRODUCT DESCRIPTION

INSTALLATION
Quick and easy to install, System PPS ringmains are ready to operate in
less time.
SIZES AND STANDARDS
Every component is guaranteed when used as indicated and solely within the
limits of this technical documentation and meets Essential Safety Criteria in
accordance with the provisions in pressure equipment directive 2014/68/UE.
The manufacturer, PREVOST, shall not be held responsible if any ringmain
or system built with System PPS components is not used or assembled
according to the specifications and limits indicated in this document.
A number of checks are required when installing and commissioning a
ringmain.
VIBRATIONS
Compressors
vibrations which could have an
adverse effect on the system.
Never connect rigid PPS tubes
directly to a compressor. Use
flexible connection hoses
instead.
If any pipes must be anchored
to a source of vibration, attach
them with rubber-lined clamps.
COLOUR
The available colours correspond to various applications :
System PPS components are finished with electrocoat treatment that also
provides optimum corrosion protection.
COMPATIBILITY WITH COMPRESSOR OILS
Aluminium does not react when in contact with compressor oils.
