A bullet-proof choice for district heating
A leading district heating pipe manufacturer has launched an innovative new range of flexible pre-insulated pipe systems with reinforced polymer service pipes that improve thermal efficiency and provide higher factors of safety.
These new options, known as Hiline FibreFlex and FibreFlex Pro, form a key part of an update to the existing Hiline range, a system of district heating pipe systems offered by the well-established pre-insulated pipe manufacturer, CPV.
With the ability to increase the operating temperature and pressure closer to that of traditional steel systems – as high as a constant 95°C at 16 bar pressure and with excursions up to 115°C – a greater factor of safety can be introduced which will give district heating network owners and operators greater confidence in their systems’ reliability, with the added benefit of improved thermal performance and no risk of corrosion.
With three flexible polymer service pipe options now available, all feature a composite polymer service pipe that is encased inside a highly-efficient bonded layer of polyurethane foam insulation, which in turn is protected by a tough corrugated outer casing of LDPE.
Mark Whettall, CPV’s managing director, comments: “Whilst a traditional steel pre-insulated pipe system can offer reliable performance if installed, operated and maintained correctly, there is always the inherent risk of corrosion and deterioration of the system’s efficiency over time.”
“Alternatively, the Hiline FibreFlex and FibreFlex Pro options provide a perfect complement to conventional pre-insulated steel pipe networks as a hybrid solution, offering greater routing flexibility, reduced installation costs and lower heat losses.”
