SPECIALISING IN HDPE PIPE & FITTINGS
Reducing pipe solar heating by up to 50% is now simple with the white coated Dynatherm® HDPE pipe.
In above ground applications where piping is exposed to direct sunlight, standard black HDPE pipe can reach more than 70°C. To avoid premature failure, this requires a decrease of 20% or more in the maximum allowable operating pressure (MAOP), and a decrease in the design life of up to 90%.
Tests show that the white coated Dynatherm® HDPE pipe reaches a maximum temperature of around 40°C in direct sunlight depending upon application conditions.
Major benefits of a reduction in the solar heating:
- Use pipe with a thinner wall thickness (one or two SDR’s higher) compared to black HDPE, or a higher operating pressure.
- Reduce length required for snaking/ thermal expansion.
- Avoid issues caused by delivery of hot water to the end use.
- Increase the design life of the pipeline.
