Izinhlobo ezimbili ezahlukene zamapayipi ensimbi engagqwali: 304SS kanye 316L

Nakhu ukuqhathanisa okuningiliziwe kwamapayipi ensimbi angu-304SS nama-316L ensimbi engagqwali:

Ukwakheka kwamakhemikhali kanye nesakhiwo:

I-304SS insimbi engagqwali ngokuyinhloko yakhiwe i-chromium (cishe u-18%) kanye ne-nickel (cishe u-8%), yakha isakhiwo se-austenitic, esinokumelana nokugqwala okuhle kakhulu kanye nokucutshungulwa.

316L insimbi engagqwali yengeza i-molybdenum ku-304, ngokuvamile equkethe i-chromium (cishe 16-18%) , i-nickel (cishe 10-14%) , ne-molybdenum (cishe 2-3%). Ukwengezwa kwe-molybdenum kuthuthukise kakhulu ukumelana kwayo ne-chloride corrosion, ikakhulukazi endaweni equkethe i-chloride ion.

Ukumelana nokugqwala:

I-304SS insimbi engagqwali inokumelana nokugqwala okuhle endaweni evamile kanye namakhemikhali amaningi, kodwa ukumelana kwayo nokugqwala kungase kuphonselwe inselelo endaweni ethile ye-asidi noma usawoti.

I-316L insimbi engagqwali imelana kakhulu nama-ion e-chloride kanye nemidiya yamakhemikhali ehlukahlukene ngenxa yokuqukethwe kwayo kwe-molybdenum, ikakhulukazi endaweni yasolwandle kanye nezicelo zezimboni ezinosawoti omningi.

Isicelo:

I-hose yensimbi engagqwali ye-304SS isetshenziswa kabanzi kumakhemikhali, uphethiloli, amandla, imishini nezinye izimboni, ukuhambisa amanzi, uwoyela, igesi kanye neminye imidiya. Ngenxa yokusebenza kwayo okuhle okubanzi, ivame ukusetshenziswa ezitsheni zasekhishini, imishini yokucubungula ukudla neminye imikhakha.

Ngenxa yokumelana nokugqwala okuhle kakhulu namandla, ipayipi lensimbi engagqwali engu-316L livame ukusetshenziswa ezindaweni ezidinga izinto eziningi, njengokuxhunywa kwepayipi lemishini yamakhemikhali, uhlelo lokuthutha lwemishini yokwenza imithi, ubunjiniyela basolwandle, njll.

Izinto ezibonakalayo:

Kokubili kunamandla aphezulu kanye nokuqina, kodwa insimbi engagqwali engu-316L ingaba namandla aphezulu kanye nokumelana nokushisa okungcono ngenxa yokwanda kwezinto ezihlanganisiwe.

Ukumelana ne-oxidation kanye nokukhasa kwensimbi engu-316L ngokuvamile kungcono kuno-304SS ekushiseni okuphezulu.

Inani:

Ngenxa yokuthi insimbi engagqwali engu-316L iqukethe izakhi eziningi ze-alloy kanye nezakhiwo ezingcono, izindleko zayo zokukhiqiza ngokuvamile ziphakeme kuno-304SS, ngakho intengo yemakethe iphakeme kakhulu.

Ukukhanda nokufaka:

Zombili zinokusebenza okuhle kwemishini, futhi zingacutshungulwa ngokugoba, ukusika nokushisela.

Enqubweni yokufaka, bobabili badinga ukunakekela ukugwema umthelela onamandla noma ukucindezela, ukuze bangabangeli umonakalo kumshini ngokwawo.

Kunomehluko omkhulu phakathi kuka-304SS kanye no-316L wamapayipi ensimbi engenasici ezicini eziningi. Ngokungeziwe ekucatshangelweni kwezindleko, ukukhetha kufanele kube nokulinganisela ngokumelene nendawo ethile yohlelo lokusebenza, uhlobo lwemidiya, nezidingo zokusebenza. Ngokwendawo evamile kanye nemidiya, i-304SS ingaba ukukhetha ukonga futhi okungokoqobo, kuyilapho i-316L ingase ifaneleke kakhulu ezindaweni lapho izidingo eziphakeme zokumelana nokugqwala zidingeka khona.
