Ipayipi lensimbi elivunguzayo lidinga ukwelashwa kwangaphandle ukwengeza ukuqina:
1. Ingaphezulu le-anticorrosive spiral tube lihlanzwa ngama-solvents nama-emulsions, angasusa izinto eziphilayo endaweni ye-spiral tube, kodwa ayikwazi ukususa ukugqwala, isikali se-oxide, i-welding flux, njll, ngakho-ke ukuhlanza kungenziwa kuphela. isetshenziswe njengendlela eyisizayo.
2. Sebenzisa ibhulashi locingo, i-sandpaper, nezinye izinto ukuze upholishe ukubukeka kwepayipi elivunguzayo elivimbela ukubola, elingasusa isikali se-oxide esixegayo, ukugqwala, i-welding slag, njll.
3. I-Chemical pickling isetshenziselwa ukunqanda ukugqwala kwepayipi, okungasusa isikali se-oxide, ukugqwala, nokunamathela okudala, futhi kungenza ukubukeka kufinyelele izinga elithile lokuhlanzeka nokuba mahhadlahhadla.
4. Injini enamandla amakhulu ishayela insimbi yokufafaza (yokujikijela) ukuze ijikeleze ngesivinini esikhulu, ukuze insimbi yensimbi, isibhamu sensimbi, ingxenye yocingo lwensimbi, amaminerali, nezinye iziqhumane zifuthwe (ziphonswe) phezu kwe-anti. -ipayipi lensimbi ye-corrosion ngaphansi komphumela wamandla we-centrifugal, angakwazi ukususwa ngokuphelele Ukugqwala, i-oxide, nokungcola, kanye nepayipi yensimbi elwa nokugqwala ingafinyelela ubulukhuni obudingekayo obufanayo ngaphansi komphumela womthelela oqinile we-abrasive kanye nokungqubuzana.
