Ipayipi lensimbi engu-3PE elwa nokugqwalaibhekisela ekushiseni kwepayipi lensimbi ukuze kuqinisekiswe ukuthi izinga lokushisa langaphakathi lepayipi lensimbi elisebenzayo kanye nezinga lokushisa elingaphezulu ndawonye endaweni yokusebenza ehlukile linciphisa ijubane noma livimbele ukugqwala nokuwohloka ngaphansi kwesenzo samakhemikhali nese-electrochemical sendawo yangaphandle, mhlawumbe ngenxa imisebenzi ye-metabolic yama-microorganisms.Indlela ye-Anti-corrosion.Indlela ye-anti-corrosion ngokuvamile iwukusebenzisa upende ebusweni bamapayipi ensimbi adlulise ukususwa kokugqwala ukuwavimbela emithonjeni ehlukahlukene egqwalayo.Lokhu kumelela enye yezindlela zakamuva zepayipi lensimbi lokulwa nokugqwala.Izinhlobo zezinto zokugqoka kanye nezimo zokufaka isicelo.Udonga lwangaphakathi lwe-anti-corrosion lusetshenziselwa ifilimu odongeni lwangaphakathi lwepayipi ukuvimbela ukugqwala epayipini nokunciphisa ukumelana nokungqubuzana.Ukuze kuncishiswe ukuchithwa kokushisa kwepayipi emhlabathini, ungqimba oluyinhlanganisela lwe-thermal insulation kanye ne-anti-corrosion yengezwe ngaphandle kwepayipi.Uma ipayipi lokuvikela langaphandle liyipayipi le-polyethylene, asikho isidingo sokulahlekelwa ukuvikelwa kokugqwala.Ngenxa yokuthi i-polyethylene inokumelana okuhle kakhulu nezinga lokushisa eliphansi, ukuzinza okuhle kwamakhemikhali, kanye nokugqwala kwe-asidi ne-alkali eningi, ayincibiliki ezincibilini ezivamile ekamelweni lokushisa futhi imunca amanzi aphansi.

I-polyethylene anti-corrosion enezingqimba ezintathu ingenye yezinhlelo zobuchwepheshe eziphambili zokulwa nokugqwala kwamapayipi agqitshwe ekhaya naphesheya.Inomsebenzi omuhle kakhulu wokulwa nokugqwala, izinga lokumunca amanzi eliphansi, namandla emishini athuthukile.Eminyakeni yamuva nje, iye yasetshenziswa kabanzi emapayipini amanzi agqitshwe ezindlini, igesi, nawowoyela.
