Ingabe amapayipi othayela adinga ukwenza i-anti-corrosion treatment lapho efaka ngaphansi komhlaba?

1.ipayipi eliphehliwe lokwelapha ukugqwala

Ipayipi elakhiwe ngothayela njengongqimba olungaphezulu lwepayipi lensimbi, ubuso balo obumbozwe ngongqimba lwezinc ukuze kuthuthukiswe ukumelana nokugqwala. Ngakho-ke, ukusetshenziswa kwamapayipi othayela ezindaweni ezingaphandle noma ezinomswakama kuyisinqumo esihle. Kodwa-ke, kwezinye izimo ezikhethekile, njengalapho kufakwa amapayipi ngaphansi komhlaba, amapayipi anamathani angase adinge ukuthi aphinde aphathwe nge-anti-corrosion coating.

2.Lapho ipayipi ligqitshwa phansi, ngokuvamile kudingekile ukucabangela ukuvimbela ukugqwala kwepayipi ukuze kuqinisekiswe ukuphepha nokuphila kwesevisi yepayipi. Epayipini elinothayela, ngenxa yokuthi ubuso balo bube nokwelashwa kwama-galvanized, kuye kwaba umphumela wokulwa nokugqwala ngokwezinga elithile. Kodwa-ke, uma ipayipi lisendaweni enzima noma ligqitshwe ekujuleni okukhulu, kuyadingeka ukwelashwa okwengeziwe okulwa nokugqwala.

3. indlela yokwenza ukwelashwa kwe-anti-corrosion coating

Lapho i-anti-corrosive coating of galvanized coating iphathwa, ingasetshenziswa ngopende noma i-coating ene-corrosion resistance resistance, ingaphinde ihlanganiswe ne-anti-corrosive tape, futhi ingaba i-epoxy-coal asphalt noma i-petroleum asphalt. Kumele kuqashelwe ukuthi lapho wenza ukwelashwa kwe-anti-corrosion, kuyadingeka ukuqinisekisa ukuthi indawo yepayipi yomile futhi ihlanzekile ukuze kuqinisekiswe ukuthi ukugqoka kungakwazi ukunamathela ngokuqinile endaweni yepayipi.

I-4. Isifingqo

Ngaphansi kwezimo ezivamile, ipayipi likathayela linomphumela othile wokunqanda ukugqwala futhi lingasetshenziswa ngokuqondile ekusetshenzisweni kokungcwatshwa. Kodwa-ke, endabeni yokujula kwamapayipi amakhulu okungcwaba kanye nendawo enokhahlo, kudingeka ukwelashwa okwengeziwe okunqanda ukugqwala ukuze kunwetshwe impilo yesevisi yepayipi. Lapho wenza ukwelashwa kwe-anti-corrosion coating, kuyadingeka ukunaka ikhwalithi yokugqoka kanye nemvelo yokusetshenziswa ukuze kuqinisekiswe ukuqina komphumela wokulwa nokubola kanye nokuzinza kokusebenza.
