Abstract (en)
[origin: WO2008113569A1] The pipe arrangement for geothermal probes according to this invention comprises at least two pipes (1, 2), having at least one layer surrounding a lumen (3), wherein one of the pipes (1, 2) serves as the feed, and the other serves as the return, and at least one of the pipes (1, 2) is made at least partially of an non-crosslinked polymer material, and is characterized in that the polymer material of the at least one layer of the pipes (1, 2) has an FNCT (fill notched creep test) value according to ISO 16770 of at least 3000h.
