 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.

Hot Water Drainage

 

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:

  1. UPVC has natural insulation properties.
     
  2. 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).
     
  3. A discharge of about 20 - 30 minutes will be necessary for the above transfer of heat to occur.
     
  4. 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.
