Steel is the material traditionally used for pipes in pre-insulated district heating systems, and is able to withstand high temperatures and pressures. This makes Vital Energi SteelFlex ideal for the pipe runs used in most district heating networks.
An aluminium diffusion barrier placed between the PUR insulation and the outer casing ensures good insulation properties – lambda 0.022 W/mK. This makes sure of consistently high heat retention throughout the service life of the pipe.
Vital Energi Flexible SteelFlex pipe systems are advantageous for house connections in district heating installations and secondary networks. CuFlex is also used for distribution of both hot and cold domestic water systems.
SteelFlex pipes can be operated up to 120°C and the maximum working pressure is 25bar.
SteelFlex flexible pipe systems are available both as single and twin pipe solutions.
