1, HDPE ground source heat pump special pipe with a large tensile strength, compared with ordinary PE water supply pipe pressure capacity, force expansion is small, PE source heat pump pipe fittings, resistance to environmental stress cracking performance, creep resistance it is good.
2, toughness, flexibility, and uneven base and dislocation of the adaptability, can withstand earthquakes and typhoons and other harsh environments.
3, raw materials to join special additives, so that the pipe has a more common than the general water supply weather resistance (including anti-ultraviolet) and long-term thermal stability.
4, corrosion resistance, for conveying corrosive media containing antifreeze and other anti-corrosion treatment, long service life.
5, the inner wall is smooth, the flow resistance is small, the flow resistance is big, saves the construction cost.
6, good wear resistance, wear resistance.
7, PHDPE ground source heat pump special pipe thermal conductivity of 0.41w / m.k, with good thermal conductivity. At the same time special pipe resistance to low temperature impact performance, can be -20 ºC -40 ºC temperature range of safe use, winter construction is not affected.
8, fused (or hot melt) easy and reliable connection, construction and maintenance is simple (during the non-stop water
