This Table shows the range of UPVC pipes of
two different pressure ratings 10 Bar and 16
bar for water supply, irrigation or for any
other under-pressure system. The pressure
ratings indicated are the continuous working
pressures at 20°C temperature. |

Temperature Pressure Relationship
|
Table 1.4 |
|
Since UPVC is a thermoplastic material, pressure
ratings must be reduced as higher temperatures are encountered.
Table 4.1 shows the percentage of the pressure rating
recommended for various working temperatures about 20° C with a
fluctuation not exceeding 5° C. UPVC pipes should not be used
for pressure duties if the operational temperature exceeds 60°
C. As with all plastic pipe lines, special precautions must be
taken where there is a possibility of water hammer or surge
pressure. Incorporating surge tanks or pressure release valves
in the system will obviate this problem. |

Theoretically pipes and fittings made from UPVC are
unsuitable for use with very hot water and this is
true for continuous flow at full bore.
However, pioneering work carried out in Great
Britain established design criteria that became
adopted into their national standards. From this
acceptance of UPVC drainage systems, the market grew
until it now has far greater sales and use than any
other above ground system and is rapidly following
the same trend with below ground drains and sewers.
The design criteria was verified and tested by
development of a Hot & Cold Cycle Test and its
principles have been adopted by many other National
Standards Organizations, ISO, Government and Private
Test Establishments.
The work carried out on UPVC drainage pipe work
produced the following design criteria:
-
UPVC has natural insulation properties.
-
Each increment of wall thickness has its own
insulation value thus the thicker the pipe the
less transfer of heat through the wall
thickness. So constant water flowing at 90° C
will only produce a surface temperature of 60° C
on the outside surface of a pipe with wall
thickness 3.2 mm
(see Figure 1).
-
A discharge of about 20 - 30 minutes will be
necessary for the above transfer of heat to
occur.
-
The softening point of UPVC plays an important
role in the above situation. Although the
temperature of the inside wall of the pipe has
exceeded the softening point, the external
surface temperature is well below. Thus the pipe
and fittings remain rigid and able to resist
loadings imposed by expansion, contraction and
soil pressures in the case of buried drains.
Also, normal discharges, from the most powerful
washing machines and domestic appliances will
not harm UPVC Drainage Systems.
Similar tests have devised for below ground
applications, but using a lower discharge
temperature to ensure that below ground drainage
also meets the same service life expectancy.
Surface Temperature Due to Discharge of Hot Water
The combination of generous wall thickness and high
softening point provide safe limits for maximum
service life. |
