Kusukela ngo-1998 iMunich International Coal Union LGU yeKomidi lokusatshalaliswa kwegesi yahlangana okufanayo watusa kakhulu ukusebenzisa ipayipi legesi elingcwatshwe i-PE njengepayipi lokusabalalisa nokudlulisa, ngemva kweminyaka engaphezu kweyi-10 yocwaningo lwesayensi nokwakhiwa kwentuthuko emhlabeni wonke, ipayipi le-PE selithuthuke laba umkhuba izinhlobo eziningi, ukusetshenziswa okuningi okuyinhloko kwepayipi.Cishe ngemva kweminyaka engu-20, impahla yamapayipi epulasitiki ayikhuphuki nje kuphela ngobuningi, futhi ithola intuthuko enkulu ekuzaleni nasekucacisweni kwayo.Ipayipi le-PE Ipayipi le-PE lisetshenziselwa ikakhulukazi amapayipi endle kamasipala nangaphandle kanye namapayipi okudonsa amanzi ezakhiwo, amapayipi endle namapayipi okukhipha indle ezimbonini zokuhlanza indle, kanye nemikhono yokuvikela yamapayipi angaphansi komhlaba nezintambo zokuxhumana.
E-China, amapayipi e-PE ahlukaniswa kakhulu abe yipayipi le-PE elidlulisa amanzi negesi, ipayipi le-PE lokunisela amanzi, ukwakha ipayipi le-PE, ipayipi lepayipi le-drainage, ipayipi lokuthuthwa kwendle eligqitshiwe, ikhebula kanye nepayipi lekhebula le-PE, ipayipi lokunisela le-PE lokunisela, ipayipi le-PE yezimboni kanye Ipayipi lekhoyili le-PE.Ipayipi le-PE ngokukhiqiza kwalo ukusetshenziswa kancane kwamandla, ukungcoliswa kwemvelo okuncane, ukusebenza kahle komkhiqizo nezinye izinzuzo, ngokuya ngokuthandwa ngabantu kanye neminyango ethintekayo ethintekayo.UMnyango Wezokwakha wase-People's Republic of China uphinde wakhipha isaziso sokuqinisa ukuphathwa nokukhuthazwa kokukhiqizwa kwamapayipi epulasitiki.
Eminyakeni yakamuva, u-85% wamapayipi okukhipha amanzi angaphakathi, amapayipi okwakha amanzi, amanzi ashisayo kanye namapayipi okushisa ezakhiwo ezintsha zokuhlala ezweni azosebenzisa amapayipi e-PE amasha, futhi ngokuyisisekelo aqede amapayipi ensimbi ajwayelekile, amapayipi ensimbi;Ukusetshenziswa kwamapayipi epulasitiki emapayipini okuphakela amanzi ezindaweni zasemakhaya kuzofinyelela ku-90%.Ngo-2020, ukuphuma kwamapayipi e-PE yaseChina kwaba amathani ayi-4,894,400, nokukhula konyaka ngo-7.19%.
Ukuhlaziywa kwethemba lomkhiqizo wepayipi le-PE esikhathini esizayo, ngenxa yesidingo esikhulu sepayipi legesi kanye nepayipi lokuphakela amanzi elingaphansi komfula, ipayipi le-PVC livinjelwe epayipini lamanzi okuphuza nezinye izizathu, ipayipi le-PE epayipini lepulasitiki lokuphakelwa kwamanzi liyisinqumo esingcono kakhulu okwamanje.Njengamanje, izinga lokukhula kokusetshenziswa konyaka kwepayipi le-PE selidlule ipayipi le-PVC-U, futhi lathuthukiswa laba iqoqo lesibili ngobukhulu lamapayipi epulasitiki emhlabeni.Eminyakeni eyishumi ezayo, ukusetshenziswa kwepayipi le-PE kuzokwanda, okuzoletha amathuba angenamkhawulo webhizinisi kanye namathemba abanzi okufaka izicelo kubahlinzeki.
