摘要

Coaxial terrestrial heat transfer has two prefabricated parts comprises of parts (1,2,3) of pipe in connection with connection union for supply and return. It has an external pipe (6) with closure cap (7) for the elongation requirement for independent position and for the adjustment of position at required length.
