Ipayipi lensimbi elivimbela ukugqwala le-3PE lempilo yamapayipi angcwatshwe libalulekile, amapayipi ezinto ezifanayo agqitshwe phansi amashumi eminyaka kanti amanye awaboli, futhi eminye iminyaka ayavuza.Ngoba basebenzisa i-coat yangaphandle ehlukene.

Lapho insimbi evamile ezosetshenziswa ezimweni ezinzima zemvelo, kuzoba nokugqwala okukhulu, okuzonciphisa impilo yepayipi lensimbi, impilo yokufakwa kwepayipi yensimbi elwa nokugqwala ide kakhulu, imvamisa ingasetshenziswa ngaphansi kwezimo ezijwayelekile ezingama-30- Iminyaka engu-50, futhi ukufakwa nokusetshenziswa okufanele nakho kungenzeka ukwenza izindleko zokugcinwa kwenethiwekhi yepayipi ziphansi, ukufakwa kwepayipi lokulwa nokugqwala kungase futhi kusethe isistimu ye-alamu, ukuhluleka kwenethiwekhi yepayipi lokubona ukuvuza okuzenzakalelayo, ulwazi olunembile lwendawo yephutha futhi kuzokhala ngokuzenzakalelayo.

Ukusebenza kokufakwa kwepayipi lensimbi le-3PE anti-corrosion kuhle, ukulahlekelwa ukushisa kungamaphesenti angama-25 kuphela wepayipi lendabuko, ukugijima isikhathi eside kungasindisa izinsiza ezinkulu, kunciphise kakhulu izindleko zamandla, futhi kusenokumelana okuqinile kwamanzi nokugqwala, futhi kudingeka umsele ngqo emhlabathini noma amanzi angathengwa, kodwa futhi kalula futhi ngokushesha ekwakhiweni, izindleko eziphansi kuhlanganiswe kuhlanganiswe, futhi emazingeni okushisa aphansi futhi has okuhle ukugqwala ukumelana, ukumelana umthelela, futhi ezimweni ezithile Ungakwazi futhi ngqo eshumekwe permafrost. .
