    An idea to enhance the thermal performance of HDPE …

    The high-density polyethylene, HDPE, pipes, which are rust-resistant, are used in many ground-source appliions that encounter heat transfer processes, in spite of its low thermal conductivity. For appliions such as ground heat exchangers, the pipe thermal conductivity plays an important role; where it is required to reject or absorb an amount of heat into or from the ground.

    The first PE pipe material used in engineering appliions was Type 50 High Density PE (HDPE) with a long term stress of 50MPa. Subsequently, Medium Density (MDPE) materials, with improved pipe properties when compared to the earlier high density materials, were used in pipes due to their improved flexibility, ductility, slow crack growth resistance and crack propagation resistance.
