Pickling Izinzuzo Of Stainless Steel Tubes

Pickling surface ukwelashwa kwensimbi engagqwali

Ngokuvamile kunezindlela ezimbili zokukhetha: amakhemikhali kanye ne-electrolytic. I-pickle yamakhemikhali kuphela esetshenziselwa ukuvikela ukugqwala kwe Ipayipi Lensimbi Engagqwalis, engasusa isikali se-oxide, ukugqwala kanye nezingubo ezindala. Ngezinye izikhathi, le ndlela ingasetshenziswa njengendlela yokwelapha kabusha ngemva kokuqhunyiswa kwesihlabathi. Nakuba ukuhlanzwa kwamakhemikhali kungenza indawo engaphezulu ifinyelele izinga elithile lokuhlanzeka nokuba mahhadladlakadlaka, izintambo okusetshenzwa kulengwa kuzo azijulile futhi kulula ukungcolisa imvelo.

Ukususwa kokugqwala ngokufafaza (ukupholisha) ukushayela i-blade yokufafaza (i-polish) ukuze ijikeleze ngesivinini esikhulu ngokusebenzisa i-motor enamandla amakhulu, ukuze insimbi yensimbi, isibhamu sensimbi, ingxenye yocingo, amaminerali kanye nezinye iziqhumane zikwazi ukufafaza (zipholisha) ubuso bepayipi lensimbi ngaphansi kwamandla we-centrifugal. Ayikwazi ukususa ngokuphelele ukugqwala, ama-oxides nokungcola, kodwa futhi ifinyelele ubulukhuni obudingekayo bepayipi lensimbi engagqwali ngaphansi komthelela nokungqubuzana kwe-abrasive.

Ngemuva kokususwa kokugqwala ngokufafaza (ukupholisha), hhayi kuphela ukukhangiswa ngokomzimba kwendawo yepayipi yensimbi engagqwali kunganwetshwa, kodwa futhi ukunamathela komshini phakathi kwe-anti-corrosion coating kanye nendawo yepayipi ingathuthukiswa. Ngakho-ke, isifutho (ukuphonsa) kuyindlela efanelekile yokususa ukugqwala yokuvikela ukugqwala kwamapayipi. Ngokuvamile, ukuqhunyiswa kwesibhamu (isihlabathi) kusetshenziswa kakhulu ukwelapha amapayipi angaphakathi, futhi ukuqhuma kwesihlabathi (isihlabathi) kusetshenziswa kakhulu ukwelapha ngaphandle kwamapayipi. Izinkinga eziningana kufanele zinakwe lapho usebenzisa isifutho (ukuphonsa) ukususa ukugqwala
