Difficult fouling: HDPE pipe have small friction coefficient and polarity; it has a good non-adhesion surface. Existing materials generally scale in the medium that PH value is more than 9, however ultra-high molecular weight polyethylene pipe do not, and the characteristic has great significance for fly ash system of the power plant.
The unique low temperature resistance: HDPE pipe has a good low temperature resistance, its impact resistance, abrasion resistance at minus 269 degrees Celsius basically unchanged, which is currently the only available engineering plastic in near absolute zero temperatures. Meanwhile, the ultra-high molecular weight polyethylene pipe has wide optimum temperature, can long-term working at -269 ℃ to 80 ℃temperature.
