Ngokuthuthuka okusheshayo kwemboni yamandla yasekhaya, ukusetshenziswa kweamapayipi ensimbi engagqwalinayo ikhula ngokushesha. Enqubweni yokwakhiwa kwamapayipi kawoyela negesi okulwa nokugqwala, kunama-capillary ensimbi engagqwali angama-304, okungamapayipi anemba kakhulu. Ukwelashwa okungaphezulu kwamapayipi ensimbi engagqwali kungenye yezinto ezibalulekile ezinquma impilo yesevisi yepayipi elilwa nokugqwala, futhi kuyisidingo esibalulekile sokuhlanganiswa okuqinile kongqimba olulwa nokugqwala kanye nepayipi lensimbi engagqwali. Ngaphandle kohlobo lokugqoka, ikhwalithi yokugqoka kanye nemvelo yokwakha, impilo ye-anti-corrosion layer incike kwikhwalithi yokwelashwa okungaphezulu kwepayipi yensimbi engagqwali, ehlanganisa cishe isigamu sokuphila. Ngakho-ke, kuyadingeka ukulandela ngokuqinile izidingo zokucaciswa kongqimba lwe-anti-corrosion ebusweni beamapayipi ensimbi engagqwalifuthi uthuthukise ngokuqhubekayo inqubo yokwelashwa kwendawo yamapayipi ensimbi engagqwali.
Njengamanje, izindlela ezivamile zokwelashwa kwendawo yamapayipi ensimbi engenasici ikakhulukazi ukuhlanza, ukukhishwa kwe-rust, pickling, njll Lezi zindlela zethulwa ngezansi.
Ukuhlanza
Ukusebenzisa ama-solvents nama-emulsions ukuhlanza ubuso bensimbi engagqwali kungasusa amafutha, amafutha, uthuli, amafutha okugcoba kanye nezinto ezifanayo eziphilayo, kodwa le ndlela ayikwazi ukususa ukugqwala, isikali, i-welding flux, njll ebusweni bensimbi engagqwali, ngakho-ke kuphela izindlela ezisizayo ekukhiqizweni kwe-anti-corrosion.
Ukususwa kokugqwala kwethuluzi
Ngokuvamile, amathuluzi afana namabhulashi ocingo asetshenziselwa ukupholisha ubuso bensimbi engagqwali, engasusa isikali esixegayo noma esiphakanyisiwe, ukugqwala, i-welding slag, njll. . Uma ingaphezulu lensimbi engagqwali linamathele ngokuqinile esikalini se-iron oxide, umphumela wokukhipha ukugqwala kwethuluzi awulungile futhi awukwazi ukufinyelela ukujula kwephethini yehange okudingwa ukwakhiwa kwe-anti-corrosion.
Ukukha
Ngokuvamile kunezindlela ezimbili zokukhetha: amakhemikhali kanye ne-electrolytic. Ipayipi lensimbi engagqwali elinqanda ukugqwala lisebenzisa kuphela ukucosha kwamakhemikhali, okungasusa isikali, ukugqwala, nokunamathela okudala. Ngezinye izikhathi le ndlela ingasetshenziswa njengendlela yokwelapha kabusha ngemva kokususwa kokugqwala kwe-sandblasting. Nakuba ukuhlanzwa kwamakhemikhali kungenza indawo engaphezulu ifinyelele izinga elithile lokuhlanzeka kanye nokuba mahhadlahhadla, iphethini yakhona yehange ayijulile futhi kulula ukungcolisa imvelo.
Ukuqhuma kwesibhamu
I-shot blasting kuyindlela yokukhipha ukugqwala. Injini enamandla amakhulu ishayela i-blade yokuqhuma ukuze ijikeleze ngesivinini esikhulu, ukuze ama-abrasives njengesihlabathi sensimbi, isibhamu sensimbi, amasegimenti ezintambo, namaminerali aqhunyiswe ebusweni bepayipi lensimbi ngaphansi kwesenzo samandla amaphakathi. Ayikwazi ukususa ukugqwala kuphela, ama-oxides nokungcola, kodwa futhi ifinyelele ubulukhuni obufanayo obudingekayo ngaphansi komthelela wobudlova nokungqubuzana kwe-abrasive.
Ngemuva kokususwa kokugqwala kokuqhuma, akukwazi nje ukwandisa umphumela wokukhangisa ngokomzimba ebusweni bepayipi lensimbi engagqwali, kodwa futhi kuthuthukise ukunamathela komshini phakathi kongqimba oluphikisana nokugqwala kanye nendawo yepayipi. Ngakho-ke, ukususwa kokugqwala kokudubula kuyindlela efanelekile yokukhipha ukugqwala yokuvikela ukugqwala kwamapayipi. Ngokuvamile, ukususwa kokugqwala okuqhumayo kusetshenziswa kakhulu ukwelapha indawo yangaphakathi yepayipi, futhi ukususwa kokugqwala okuqhumayo kusetshenziswa kakhulu ukwelapha ngaphandle kwepayipi. Izinkinga eziningi kufanele zibhekwe lapho kusetshenziswa ukususwa kokugqwala kwesibhamu.
