1.Kusiyanitsa kwakukulu pakati pa PE-RTⅡ mtundu wa mapaipi otchinga okosijeni ndi PE-RT, PE-X, PP-R, PE ndi mapaipi ena ndikuti PE-RTⅡ mtundu ndi gawo la magawo atatu ophatikizidwa mu gawo limodzi, momwe Gawo la EVOH limatchinga mpweya. Madzi kapena mpweya womwe umalowa mu chitoliro umakulitsa kwambiri moyo wautumiki wa ma valve zitsulo, masiwichi, ma boilers, otolera madzi ndi mbali zina zachitsulo mu dongosolo lonse la mapaipi omwe amakalamba chifukwa cha okosijeni. Ngati chitoliro chotchinga mpweya chikugwiritsidwa ntchito m'madzi apampopi, ngakhale madziwo sayenda kwa nthawi yayitali, sichidzawonongeka chifukwa cha okosijeni, ndipo mabakiteriya omwe amakhala ndi okosijeni sangathe kuutulutsa.
2.PE-RT II mtundu wa oxygen chotchinga chitoliro khoma PE-RT chitoliro ali ndi kutentha kwambiri kukana.
3.Ilinso ndi mwayi wosakhala m'dera pambuyo pa kukhazikitsa ndi kugwiritsa ntchito mapaipi a PE-RT.
4.Ilinso ndi ubwino wokhala omasuka pambuyo pa kukhazikitsa ndi kugwiritsa ntchito mapaipi a PE-RT.
5.Ilinso ndi ubwino wokonza chilengedwe pambuyo pa kukhazikitsa ndi kugwiritsa ntchito mapaipi a PE-RT.
6.Ilinso ndi ubwino wa moyo wautali wautumiki wa mapaipi a PE-RT.
7.Ilinso ndi ubwino wokonza mosavuta mapaipi a PE-RT.
8.Oxygen chotchinga mapaipi amakhalanso ndi makhalidwe ofanana ndi ena apamwamba kutentha zosagwira pansi Kutentha mapaipi: asidi kukana, alkali kukana, dzimbiri kukana, kukana kukalamba, sanali poizoni ndi zoipa, palibe dzimbiri, kukana madzi ang'onoang'ono, palibe makulitsidwe, anti -kuzizira kozizira, anti-leakage, kutentha pang'ono, kupulumutsa mphamvu, ukhondo, wokonda zachilengedwe, wosinthasintha komanso wosavuta kupindika, komanso kudziletsa kudziletsa kupsinjika kopindika.
