Mayelana nokuhlanzwa kwepayipi elingenalutho legobolondo likawoyela:
Amapayipi okugoqa uwoyela angenalutho ayahlanzwa futhi afika endaweni yokucubungula.Ngaphambi kokucutshungulwa okusemthethweni, ibala likawoyela, inhlabathi ye-lime, ukugqwala kwesikali se-oxide kanye nokunamathela okudala endaweni yangaphakathi nangaphandle yepayipi kufanele kuhlanzwe.Izindlela zokususa ukugqwala zihlanganisa okwenziwa ngesandla, ngomshini, ngokufutha, ukukha, njll. Esikhathini esidlule, indlela yokufafaza yayisetshenziswa kakhulu ekukhipheni ukugqwala kwamapayipi omoya-mpilo.Manje, i-pickling isetshenziselwa ukususa ukugqwala, futhi umphumela muhle kakhulu.Uma uhlanza ngomoya ocindezelweyo noma amanzi, isivinini somfutho wamanzi noma umfutho womoya ungafinyelela ku-15x20m/s, ongasusa ukungcola endaweni yepayipi, kodwa awukwazi ukususa ungqimba lokugqwala, isikali se-oxide, i-burr, isimila sokushisela kanye nesimila esikhiphayo.
