Kukhona ingqikithi yemikhiqizo engu-16 yamapayipi okushisa aphansi e-PE-RT, ahlukaniswe ngezincazelo ezi-4 kusuka ku-dn16-dn32. Imikhiqizo ihlukaniswe ngamamaki angu-5 ngokuvumelana nengcindezi: PN 1.0MPa, PN 1.25 MPa,
I-PN 1.6 MPa, PN 2.0 MPa kanye ne-PN 2.5 MPa. Imishini yamanzi ihlome ngokugcwele futhi imikhiqizo isetshenziswa emkhakheni wokushisa kwe-georadiant.
I-1.Izinto ezisetshenziswayo ezinhle kakhulu kanye nokuqinisekiswa kwekhwalithi: izinto zokusetshenziswa ezivela eNingizimu Korea zisetshenziselwa ukukhiqizwa, futhi umkhiqizo ngamunye oqediwe uthola ukuhlolwa kokucindezela komoya endaweni ngengcindezi ye-0.8MPa ukuze kuqinisekiswe ikhwalithi yomkhiqizo ozinzile nothembekile.
I-2.Impilo yesevisi ende: ngaphansi kwezimo zokushisa zokusebenza okungu-70 ℃ kanye nengcindezi engu-0.4MPa, ingasetshenziswa ngokuphepha iminyaka engaphezu kwengu-50.
3.I-Thermal conductivity enhle: I-thermal conductivity ingu-0.4W/mK, ephakeme kakhulu kune-PP-R's 0.21W/mK kanye ne-PB's 0. 17W/mK, engagcina amandla amaningi ezinsizeni zokushisisa.
4.educe umthwalo wokushisa wesistimu: ukulahlekelwa kwe-friction odongeni lwangaphakathi lwepayipi kuncane, umthamo wokuthutha uketshezi u-30% uphakeme kunamapayipi ensimbi obubanzi obufanayo, futhi ukucindezela kokushisa kwesistimu kuncane.
5.Indlela yokuxhuma iyaguquguquka futhi kulula ukuyifaka: ingaba uxhumano lwe-hot-melt noma uxhumano lwemishini. Indlela yokuxhuma iyavumelana nezimo futhi kulula ukuyifaka, kuyilapho i-PE-X ingaxhunywa ngomshini kuphela.
I-6.Izinga lokushisa eliphansi le-brittle: Ipayipi inokumelana okuhle kakhulu kokushisa okuphansi futhi ingakhiwa ngisho nangaphansi kwezimo zokushisa eziphansi ebusika, futhi ipayipi ayidingi ukushiswa ngaphambili lapho igoba.
I-7.Ukwakhiwa nokufakwa kalula: kunokuguquguquka okuhle, futhi ngeke kube khona "i-rebound" into lapho igobile, ekulungele ukwakhiwa nokusebenza; ipayipi lihlanganiswe, okulula ukulakha nokulifaka.
8.Ukumelana nomthelela okuhle kakhulu: Ukumelana nomthelela izikhathi ezi-5 kunamapayipi e-PVC-U. Umkhiqizo awonakele kalula ngesikhathi sokwakhiwa futhi unengozi encane yokuphepha.
