Umbhobho wentsimbi we-3PE ochasene ne-corrosiveibhekisa ekugqumelweni kombhobho wentsimbi ukuqinisekisa ukuba ubushushu bangaphakathi bombhobho wentsimbi osebenzayo kunye nobushushu bomphezulu kunye kwindawo yokusebenza eyahlukileyo bucotha okanye buthintele ukubola kunye nokuwohloka phantsi kweekhemikhali kunye nesenzo se-electrochemical medium yangaphandle, mhlawumbi ngenxa imisebenzi ye-metabolic ye-microorganisms.Indlela yokunqanda ukubola.Indlela ye-anti-corrosion idla ngokufaka ipeyinti kumphezulu wemibhobho yentsimbi egqithise ukususwa komhlwa ukuvalela kwimidiya eyahlukeneyo eyonakalisayo.Oku kubonisa enye yeendlela zamva nje zombhobho wensimbi wokulwa nokubola.Iintlobo zezinto zokugquma kunye neemeko zesicelo.Udonga lwangaphakathi lwe-anti-corrosion lufakwe kwifilimu eludongeni lwangaphakathi lombhobho ukukhusela ukubola kumbhobho kunye nokunciphisa ukuxhathisa i-frictional.Ukunciphisa ukutshatyalaliswa kobushushu bombhobho emhlabeni, umaleko odibeneyo we-thermal insulation kunye ne-anti-corrosion yongezwa ngaphandle kombhobho.Ukuba umbhobho wokukhusela wangaphandle ngumbhobho we-polyethylene, akukho mfuneko yokulahlekelwa ukukhuselwa kwe-corrosion.Ngenxa yokuba i-polyethylene inokumelana nobushushu obuphantsi, ukuzinza okuhle kweekhemikhali, kunye ne-asidi eninzi kunye ne-alkali corrosion, ayinyibiliki kwizinyibilikisi eziqhelekileyo kubushushu begumbi kwaye ifunxa amanzi aphantsi.

I-polyethylene ye-anti-corrosion enemigangatho emithathu yenye yezona nkqubo ziphambili zobuchwepheshe zokuthintela ukubola kwangaphandle kwemibhobho engcwatywe ekhaya nakwamanye amazwe.Inomsebenzi obalaseleyo wokuchasana nomhlwa, isantya sokufunxa amanzi asezantsi, kunye namandla omatshini aphezulu.Kwiminyaka yakutshanje, iye yasetyenziswa ngokubanzi nangakumbi kwimibhobho yamanzi angcwatywayo, igesi, neoli.
