UPS & STANDBY POWER FEATURE
nature, back-up generators are used infrequently, so it is vital that the pipework can quickly and efficiently transfer fuel to the generator when needed, after a prolonged period of not being used, which is where steel systems have some limitations. The smooth bore and corrosion
resistant properties of plastic pipes should be a major consideration when specifying fuel pipework, as this eliminates leak paths being created, as a result of corrosion, that can both harm the environment and provide inefficient supply of fuel. With no risk of contamination, contractors and end users can also be confident that the fuel will remain uncontaminated, avoiding any damage to the generator or associated equipment.
READY FOR ACTION In addition, the smooth bore of plastic pipe is retained over the lifetime of the system, ensuring there is no restriction to the flow of fuel, with optimum flow rates being maintained whenever the system is called into action. It is vital, when considering pipework for emergency fuel applications, that the selected material can provide
time, while also eliminating the need for skilled welders and hot works permits, adding to a further reduction in costs.
reassurances of its fuel transfer performance over a long period of time. Pipework selection can also impact on
the installation process and the time and costs involved. The installation of plastic pipework for
fuel applications can significantly reduce the time and costs of an emergency power supply installation, compared with a steel equivalent, whether below or above ground.
REDUCED INSTALLATION TIME Purpose-designed plastic pipework systems, such as Durapipe PLX, benefit from a fusion welding jointing method, significantly reducing the installation
LONGEVITY OF MATERIALS The PLX system is a specialist pipework solution that is designed to cater for a variety of fuel blends, and is manufactured in a robust polyethylene material that provides excellent resistance to long term stress cracking. Additionally, its impressive durability makes it ideal for use in emergency power applications, where it is imperative to install a system that does not have to be regularly maintained or replaced. While building on the performance
quality of steel, alternative pipework solutions also address its limitations and need to be more readily explored in the initial specification process. The pipe network used for emergency fuel supply needs to be considered at the design stage to ensure the most cost effective system, that offers the required performance benefits, is installed. Durapipe UK is a leading
manufacturer of high performance, thermoplastic pipework systems.
