Amapayipi ensimbi e-anti-corrosion adlala indima ebalulekile futhi ehlukene ekuphileni kwansuku zonke kwabantu. Amapayipi ensimbi avimbela ukugqwala ngokuvamile abhekisela ekusetshenzisweni kwezinqubo ezikhethekile zokwenza ukwelashwa okunqanda ukugqwala kumapayipi ensimbi avamile (njengamapayipi angenamthungo, amapayipi ashiselwe), ukuze amapayipi ensimbi abe nezinto ezithile zokunqanda ukugqwala. Ikhono lokugqwala livame ukusetshenziselwa ukungangeni kwamanzi, ukugqwala, i-anti-acid ne-alkali, i-anti-oxidation nezinye izici. Ngokuvamile, ipayipi lensimbi le-PE anti-corrosion libhekisela kupayipi lensimbi le-polyethylene elivimbela ukugqwala, okuwumbhalo we-tubular ocutshungulwa isayensi nobuchwepheshe obuthuthukile. Amapayipi ensimbi e-PE anti-corrosion asetshenziswa kakhulu kuwoyela, igesi yemvelo, igesi yedolobha, ukuphakelwa kwamanzi edolobha, amapayipi amalahle anodaka, njll.
Izinyathelo ezihambisanayo zokulwa nokugqwala nazo zingenziwa ezindongeni zangaphakathi nangaphandle zamapayipi ensimbi ngokuvumelana nezidingo ezahlukene. Ezivamile i-epoxy coal tar pitch anti-corrosion steel pipes, polyurethane coating anti-corrosion, udaka lukasimende oluvimbela ukugqwala odongeni lwangaphakathi lwamapayipi ensimbi alwa nokugqwala, njll. Amapayipi ensimbi e-anti-corrosion asetshenziswa ikakhulukazi ezidingweni ezikhethekile noma Izinkambu zobunjiniyela ezindaweni ezinzima.
Ipayipi lensimbi elilwa nokugqwala libhekisela emapayipini ensimbi acutshungulwe ngobuchwepheshe bokulwa nokugqwala, okungavimbela ngokuphumelelayo noma kunciphise isivinini sokugqwala okubangelwa ukusabela kwamakhemikhali noma kwe-electrochemical ngesikhathi sokuthutha nokusetshenziswa. Ngokusho kwedatha yezibalo yezwe lethu, ukulahlekelwa okuqondile kwezomnotho kokugqwala kwamapayipi ensimbi asekhaya kungaphezu kwama-yuan ayizigidi eziyizinkulungwane ezingama-280 njalo ngonyaka, futhi ukulahlekelwa konyaka emhlabeni wonke ngenxa yokugqwala kwamapayipi ensimbi kufinyelela kumadola ayizigidi eziyizinkulungwane ezingama-500. Amapayipi ensimbi angagqwali angavimbela noma anciphise ukugqwala ngempumelelo, andise impilo yesevisi yamapayipi ensimbi, futhi ehlise izindleko zokusebenza zamapayipi ensimbi. Izici zamapayipi ensimbi elwa nokugqwala ukumelana nokugqwala, akukho ukuvuza, ukuqina okuphezulu, ukuguquguquka okuhle kakhulu, ukumelana kahle nokuklwebheka, nokumelana kahle nokusakazwa ngokushesha kokuqhekeka. Kokunye, impilo yesevisi yamapayipi ensimbi elwa nokugqwala inkulu noma ilingana nayo Ngaphansi kwemvelo engu-60 degrees Celsius, ingaba neminyaka engaphezu kwengu-50.
Ngaphezu kokuthuthukisa impilo yesevisi yamapayipi ensimbi ngokusebenzisa i-anti-corrosion, kubonakala futhi kulezi zici ezilandelayo:
1. Ukuhlanganisa amandla omshini wepayipi lensimbi kanye nokumelana nokugqwala kwepulasitiki.
2. Udonga lwangaphandle lungaphezu kuka-2.5mm, olumelana nokuklwebheka futhi lumelana namaqhubu.
3. I-coefficient ye-friction yodonga lwangaphakathi incane, i-0.0081-0.091, enciphisa ukusetshenziswa kwamandla.
4. Udonga lwangaphakathi lubushelelezi futhi akulula ukukala, futhi lunomsebenzi wokuzihlanza.
