i-alloy 904L tubing (UNS N08904) ukuze isetshenziswe ezinhlelweni ezidinga ukumelana nokugqwala okumaphakathi kuya kokuphezulu.Ingxubevange 904L iyi-carbon high alloy austenitic insimbi engagqwali ephansi, eyasungulwa ekuqaleni ukuze imelane nokugqwala ekuxubeni i-sulfuric acid.Ngenxa yokuhlanganiswa kwe-chromium, i-nickel, i-molybdenum nethusi, leli banga liye lathuthuka kakhulu ukumelana nama-acids anciphisa aqinile, ikakhulukazi i-sulfuric acid.I-alloy 904L ishubhu iphinda imelana ngokwedlulele nokuhlaselwa kwe-chloride kusuka kukho kokubili ukugqwala komgodi/umfantu kanye nokuqhekeka kokugqwala kwengcindezi.Ingxubevange 904L ayiwona uzibuthe kuzo zonke izimo, inokuqina okumangalisayo, futhi inokwakheka okuhle nokushisela.
Ngenxa yalezi zakhiwo, umuntu angathola ishubhu ye-alloy 904L ezinhlelweni eziningi.Lezi zisukela kumishini yokukhuhla izinto ezisetshenziswayo kuye kumishini yokukhiqiza i-asidi nomanyolo, ukucutshungulwa kwe-pulp nephepha, izinsiza zokupholisa amanzi olwandle.Isetshenziswa ezinqubweni eziqukethe i-sulfuric noma i-phosphoric acid, i-904L ibonisa ukumelana kwayo okuhle kakhulu nokugqwala okuvela kulawo ma-asidi.Izimboni zephepha, igesi, ezemithi kanye namakhemikhali nazo zisebenzisa i-904L ukumelana kwayo futhi isebenzise ku-400-450 degrees C. Ingxubevange engu-904L ishubhu ingashiselwa, ifakwe ngomshini, iphathwe ngokushisa, ifakwe i-anneal, iqiniswe futhi ibandayo isetshenziselwe izinhloso eziningi.
I-UNS NO8904, evame ukubizwa ngokuthi 904L, iyinsimbi engagqwali ephansi ye-carbon high alloy austenitic esetshenziswa kakhulu ezinhlelweni lapho izakhiwo zokugqwala ze-AISI 316L ne-AISI 317L zinganele.
Ukwengezwa kwethusi kuleli banga kulinikeza izakhiwo ezimelana nokugqwala okuphakeme kunezinsimbi ezingenasici ze-chrome ze-nickel, ikakhulukazi kune-sulphuric, phosphoric kanye ne-acetic acid.Nokho, kukhona ukusetshenziswa okulinganiselwe nge-hydrochloric acid.Futhi inokumelana okuphezulu nokufaka izixazululo ze-chloride, ukumelana okuphezulu kukho kokubili ukuqhekeka nokugqwala kwengcindezi.I-alloy 904L isebenza kangcono kunezinye izinsimbi ezingenasici ze-austenitic ngenxa yokuhlanganiswa okuphezulu kwe-nickel ne-molybdenum.
Ibanga alinawo uzibuthe kuzo zonke izimo futhi linokwakheka okuhle kakhulu nokushisela.Isakhiwo se-austenitic sinikeza leli banga ukuqina okuhle kakhulu, ngisho naphansi kwamazinga okushisa e-cryogenic.
Okuqukethwe kwe-chromium ephezulu kukhuthaza futhi kugcine ifilimu engenzi lutho evikela into esetshenziswayo ezindaweni eziningi ezonakalisayo.I-904L inokumelana okukhulu nemvula yezigaba ze-ferrite ne-sigma ekupholiseni nasekushiseleni kunezinye izinsimbi ezingenasici eziqukethe i-molybdenum njenge-316L ne-317L.Abukho ubungozi bokugqwala kwe-intercrystalline ekupholiseni noma ekushiseleni ngenxa yokuqukethwe kwekhabhoni ephansi.Izinga lokushisa eliphezulu lesevisi yalo liku-450°C.
Leli banga liwusizo ikakhulukazi ekulawuleni nasekusetshenzisweni kwamashubhu wezinsimbi lapho i-316 ne-317L ingafaneleki.
I-904L insimbi engagqwali ihlanganisa i-molybdenum nethusi nensimbi ukuze kukhuphuke kakhulu ukumelana nokunciphisa ama-asidi afana ne-sulfuric acid.Imelana kahle kakhulu nama-chloride endaweni ukuze igobe kancane kanye nokugqwala kwemifantu, kanye nokuqhekeka kokugqwala kwengcindezi.

Izinhlelo zokusebenza
I-904L insimbi engagqwali isetshenziswa kakhulu ezimbonini zamakhemikhali, ezemithi, zikawoyela negesi.Izicelo ezijwayelekile zihlanganisa amathangi, ama-valve, izishintshi zokushisa, ama-flange nama-manifolds.Ukwengezwa kwethusi ekwakhiweni kwensimbi engagqwali engu-904L kusiza ukufaneleka kwayo kwezingxenye ezifana namathangi neminye imikhiqizo esetshenziswa ekuphatheni i-sulfuric ne-phosphoric acid.
