Izinhloso eziphambili zokwenza lula ukusebenza kwamandla amapayipi wamanzi amabili ngamabili: umuntu ukuqinisekisa umthamo wokudluliswa kwamanzi, ukuvikela indawo enkulu yokulahleka kwengcindezi yamanzi, ukuze akwazi ukuhambisa amanzi emlilweni nasezindaweni ezibucayi eziphuthumayo; Okwesibili ukunciphisa ukulimala kwepayipi ukwenza lula ukulungiswa okusheshayo. Ngamanye amagama, lapho ebhekene nezinhlekelele zokuzamazama komhlaba, uhlelo lokuhlinzekwa kwamanzi kufanele lube nokuvumelana okuphezulu.
Ukuvimbela amakhefu asemqoka amanzi kubalulekile ukuze ulondoloze ukusebenza okujwayelekile kohlelo lokuhlinzekwa kwamanzi. I-PE4710 (elilingana ne-PE100) I-Piping System inethuba eliphansi kakhulu lokuqhuma nokuvuza kwanoma yiliphi ipayipi lamanzi, isiza ukufeza zonke izinhloso ezingenhla.
Ukusakazeka kwegagasi nokuguquguquka komhlaba unomphela kuyizimbangela eziphambili zomonakalo wepayipi ongcwatshwe. Ngenxa yokuba khona kwama-axial Force kanye nokuqothuka kwengcindezi, ukunyakaza komhlaba kuholela ekunciphiseni kwe-axioli ne-wipeline. Izinto zokwakha ezinamandla amakhulu (ukucindezela okuvunyelwe okuphezulu) ngokuvamile kunekhono elilinganiselwe lokulimaza. Izinto ze-ructile ezimelwe yi-polyethylene (pe) (ukucindezela okuvumelekile) kunekhono elihle lokukhubazeka kanye nobunzima.
Ikhono lokuzamazama komhlaba ohlelweni lwepayipi lubonakala ngokuvumelana kwalo kubunzima obungaphezulu. Ukuthuthukiswa kokuzamazama komhlaba noma ukuthuthukiswa kwe-saismic kungadala ubunzima emhlabathini ngokwanele ukulimaza ngisho namapayipi asengozini kakhulu. Ukuqhekeka Okubi, ukugeleza komhlaba, ukuguquguquka kwenhlabathi kuya odakeni kanye nokusatshalaliswa okulandelayo kanye / noma ukusakazeka kwe-lateral, ukuxhasa umhlabathi kanye nokukhuphuka kungadala ubunzima obukhulu, okuholela ekulimaleni kwezindawo ezinkulu zamapayipi angcwatshwe. Ithebula B-1 Uhlu idatha ye-Ground Train ebonwe emhlabeni wonke ngenxa yokuguqulwa komhlaba unomphela.

Uhla oludingekayo lobunzima bomhlaba lwamapayipi luphakathi kuka-0.05% no-4.5%. Ngokombiso we-2008 nguMnyango Wezokuphenya Ngogesi WaseMelika, izilinganiso zezicucu zezinto ezibonakalayo ze-PE4710 zanikezwa. Ku-50 ° F. (10 ° C) lokushisa, isimo esijwayelekile sesivuno se-Tensile se-PE4710 Pipe singama-9.9%, kanti isilinganiselo esimaphakathi se-tinsile ntensain singu-206%. Ipayipi le-polyethylene lizohamba liphendula ngokunyakaza komhlaba, kunokuba alwele imithwalo engadala amapayipi aqinile noma acwebezelayo ukuba aphule. Emicimbini eminingi yokuzamazama komhlaba, ipayipi eliphakeme (lelded) eliphakeme le-polyethylene (HDPE) ipayipi lizogoba, kepha ngeke liphule noma lihlukanise (ukuxhumana okungelona uphawu), ngaleyo ndlela kugcina ukuhlinzekwa kwamanzi. Kufanele kuqashelwe ukuthi konke ukuxhumana kwamapayipi we-PE nezinye izakhiwo, izikhungo ezingekho emthethweni kanye nezinto ezingaphansi kwemithwalo ehlukene ehlukene. Ukuxhumeka kwalezi zingxenye kufanele kuhlelwe ngokucophelela futhi kuklanyelwe ukunciphisa ingozi yokuqhuma.
Uhlobo lwesivuno lwe-Tensile lwepayipi le-PE4710 lucishe luphindwe kabili kwe-Ground Train olubangelwa ubukhulu obuphezulu, futhi ubunzima bokugcina be-PE4710 bungaphezulu kwezikhathi ezingama-40 ezingezinciphisi eziphezulu. Ukusebenza okutholwe ukubalwa kwethiyori kuyahambisana nokusetshenziswa kwepayipi le-polyethylene ekuzamazamazweni. Umugqa wokunikezela wamanzi we-welded HDPE wenza kahle ekuzamazameni komhlaba. Ithebula B-2 linikeza ukubonwa okuyingxenye kokuzamazama komhlaba okwedlule eJapan (Omuro naseHemono, 2018).

Ukusebenza kokuzamazama komhlaba kwamapayipi kufanele kuhlolwe, kufaka phakathi ubulukhuni, umthamo we-axial, i-radius yokugoba okuvumelekile, amandla ahlanganyelwe, ukuqina kanye nesimo sepayipi elikhona. Inani elikhulu lesipiliyoni sokuzamazama komhlaba libonisa ukuthi amapayipi aphezulu we-HDPE ahlinzeka ngamazinga aphezulu we-ASTM angagcina ukusebenza okujwayelekile ngaphansi kwezimo zomthwalo wokuzamazama komhlaba. Lapho izidingo zokusebenza kokuzamazama komhlaba zokuhlinzekwa kwamanzi ziphezulu ziphezulu, ukusetshenziswa kwamapayipi we-welded HDPE kufanele kubhekwe, ngoba ukusebenza kwamapayipi we-HDPE kuthembeke kakhulu, futhi bangazivumelanisa nezimo ezahlukahlukene zomhlaba ezikhiqizwe ukuzamazama komhlaba futhi zilondoloze ukusebenza okujwayelekile.
