A CHALLENGE WITHOUT RULES
Although the supply of hot and cold water is primarily managed with metal pipework systems, a growing interest has recently been shown in Italy towards solutions based on the latest generation of plastic materials: in this context, the absence of corrosion and a greater resistance to thermal effects are the key elements of high-temperature resistance of polyethylene (PE100 RT). The strengths of pipelines PE100 RT cover a wider range of operating temperatures, with major application sectors such as geothermal or the offshore oil industry.
The transport of water on the island of Volcanoes (Sicily), where there are numerous cracks in the ground called “sulphurous” characterised by steam and gas emissions, an interesting challenge has been represented in the realisation of a vast network of underground piping systems in the conveyance of waste water to be treated and the transport of sea water to the purification plants for the production of drinking water. Due to the thermal characteristics of the subsoil, the PE100 RT was chosen as the base material from IMPRE.CO.GE buyer. Ltd. and the study of Altieri spa design (Thiene) for the construction of a network of about 10 km of Reno 100 HTS pipes, sizes ranging from DN200 to DN355 (SDR 11) taking into account the various parameters, such as chemical resistance to channelled water, abrasion resistance due to the transport of solid substances and the effect of expansion due to thermal release.
