FAQ « Diacon Australia

The HDPE material currently used by DIACON does have some self-extinguishment properties, but it will burn when a burning fuel source is present. In the event of a dramatic coal belt fire, it could be legitimately argued that the additional fuel load provided by the DIACON guarding would only amount to a few percent, when compared to the fuel load provided by the coal and the rubber belting.

Performance of buried HDPE pipes - part II: total …

It is shown that the relative flexure stiffness, the type of compactor and the unit weight of soil cover have significant effects on the total deflection of the pipe. Based on analyses of the finite-element simulation results and experimental data, two empirical formulas with five parameters are proposed to describe the total deflection of HDPE pipes in both the vertical and horizontal directions.
