Ngokuthuthuka okuqhubekayo komnotho waseShayina, izwe lithuthukisa imboni yezamandla ngamandla.Amapayipi ahamba amabanga amade kawoyela negesi ayindlela ebalulekile yokuphepha kwamandla.Enqubweni yokwakhiwa kwe-anti-corrosion yamapayipi kawoyela (igesi), ukwelashwa okungaphezulu kwamapayipi ensimbi e-anti-corrosion spiral kunquma impilo yesevisi yamapayipi.Esinye sezici ezibalulekile yisisekelo sokuthi ungqimba oluphikisana nokugqwala kanye nepayipi lensimbi lingahlanganiswa ngokuqinile.Ngokusho kokuqinisekiswa kwesikhungo socwaningo, impilo ye-anti-corrosion layer incike ohlotsheni lokumboza, ikhwalithi yokugqoka kanye nendawo yokwakha.Ukwelashwa okungaphezulu kwepayipi lensimbi elivunguzayo elilwa nokugqwala kuthinta impilo yongqimba olulwa nokugqwala cishe ngama-50%.Ngakho-ke, kufanele ihambisane ngokuqinile ne-anti-corrosion layer.Linganisa izidingo ebusweni bamapayipi ensimbi, uhlole ngokuqhubekayo futhi ufingqe, futhi uthuthukise ngokuqhubekayo izindlela zokwelapha ezingaphezulu zamapayipi ensimbi.

Yini okufanele yenziwe ebusweni bepayipi lensimbi elivunguzayo le-high-frequency anti-corrosion?

1. ukuhlanza

Sebenzisa i-solvent ne-emulsion ukuhlanza ubuso bensimbi ukuze ususe uwoyela, amafutha, uthuli, okokugcoba nokunye okufanayo okuphilayo, kodwa ayikwazi ukususa ukugqwala, isikali, ukugeleza, njll. ebusweni bepayipi lensimbi, ngakho-ke isetshenziswa kuphela njenge izindlela ezisizayo ekukhiqizeni ipayipi lensimbi elilwa nokugqwala..

2. ithuluzi ukugqwala ukususwa

Ingaphezulu lepayipi lensimbi lipholishwa ngokuyinhloko kusetshenziswa ibhulashi locingo noma okufanayo ukuze kukhishwe isikali esixegisiwe noma esiphakanyisiwe, ukugqwala, i-welding slag, nokunye okunjalo.Ukususwa kokugqwala kwethuluzi lesandla kungafinyelela izinga le-Sa2, futhi ukususwa kokugqwala kwethuluzi lamandla kungafinyelela izinga le-Sa3.Uma ubuso bensimbi yensimbi bunamathele esikalini se-iron oxide, umphumela wokukhipha ukugqwala wethuluzi awulungile, futhi ukujula kwehange okudingekayo ekwakhiweni kwe-anti-corrosion akukwazi ukutholakala.

3. ukukha

Ngokuvamile, ukuhlanza amakhemikhali kanye ne-electrolysis kusetshenziselwa ukwelashwa kokukhetha.Ipayipi lensimbi elivunguzayo le-Anticorrosive spiral liphathwa kuphela ngekhemikhali yokukhetha, engasusa isikali, ukugqwala kanye nokunamathela okudala, futhi ngezinye izikhathi ingasetshenziswa njengendlela yokwelapha kabusha ngemva kokuqhunyiswa kwesihlabathi nokususwa kokugqwala.Nakuba ukuhlanzwa kwamakhemikhali kungafinyelela izinga elithile lokuhlanzeka kanye nokuba mahhadlahhadla, iphethini yayo yehange ayijulile futhi kulula ukungcolisa imvelo.
