Mapaipi eHDPE anogara kwenguva refu, anogara kwenguva refu, uye haapindi mumatambudziko uye haapindi muzvinhu zvakawanda zvemakemikari nemakemikari. Hunhu hwepaipi hwaireva kuti panofanira kunge pasina kugadziriswa kwakawanda kupfuura zvimwe zvinhu zvepaipi uye kuve nechokwadi chekuti mvura inoyerera zvakanaka muhupenyu hwayo hwese.
Mhinduro yeChuangRong system yaisanganisira mapaipi, ma electrofusion couplers, michina ye electrofusion, rutsigiro rweinjiniya, maturusi ekuisa akakosha, uye kudzidziswa.
Mabasa aya anosanganisira kuchera mapaipi mumigwagwa, kuisa mapaipi mugomba, kubatanidza, kuyedza mvura uye kuzadza ivhu rakacherwa.
