Ingxubevange 28i-alloy ephezulu ye-multi-purpose austenitic stainless steel yenkonzo kwiimeko ezinobungozi kakhulu. Ibakala libonakaliswa ngoku:
- Ukumelana ne-corrosion ephezulu kakhulu kwii-asidi ezinamandla
- Ukumelana kakuhle kakhulu noxinzelelo lwe-corrosion cracking (SCC) kunye ne-intergranular corrosion kwiindawo ezahlukeneyo.
- Ukuxhathisa okuphezulu kwimingxuma kunye nokuhlwa kwemingxuma
- Ukuwelda okulungileyo

Ngenxa yezinto ezigqwesileyo zokugqwala, iSanicro® 28 ingasetyenziswa kwezona ndawo zihlukeneyo. Uluhlu olungezantsi yimizekelo embalwa yezicelo apho le ngxube ifaneleka ngokukodwa.
Phosphoric acid
Namhlanje,Ingxubevange 28 okanyeI-Sanicro 28 yeyona nto isetyenziswa kakhulu kwintsimbi yesinyithi kwiityhubhu ze-evaporator ekwenzeni i-asidi ye-phosphoric ngendlela "emanzi". Iiyunithi ezininzi sele zisenkonzweni iminyaka engaphezu kwe-10. Abatshintshi bobushushu begraphite, endaweni yeSanicro 28, babesoloko beneengxaki eziphindaphindiweyo ngeetyhubhu ezaphukileyo kunye nokulahleka kwemveliso.
Iasidi yesulfuric
Ingxubevange 28 okanyeI-Sanicro 28 sisixhobo esifanelekileyo semibhobho kunye nokutshintshiselana kobushushu, ngakumbi kwindawo ephakathi kwe-40 kunye ne-70% ye-asidi edakiweyo nangaphezulu kwe-85%.Ingxubevange 28 okanyeI-Sanicro 28 inoxhathiso oluphantse lufane ne-Alloy C kwi-asidi egxininisiweyo (98% H2SO4).
Ioli kunye negesi
Ingxubevange 28 okanyeI-Sanicro 28 isetyenziselwa i-tubing yemveliso, i-casing kunye ne-liners kumaqula anzulu, amuncu. Izinto eziphathekayo zikwacetyiswa kwimithombo yeoli eneendawo ezinobungozi. Ngezi njongo, iibhubhu zinikezelwa ngokubanda ziqengqiwe ngamandla aphezulu. Kwimeko yesisombululo,Ingxubevange 28 okanyeI-Sanicro 28 ikwasetyenziswa njengemibhobho yokuthutha i-oyile eyonakalisayo kunye nerhasi kunye nokutshintsha ubushushu kwiindawo zonyango. Iifowuni ze-Sanicro ze-28 zisetyenziselwa ukuthoba izixhobo kunye nezixhobo zokulawula kwimithombo ye-oyile kunye negesi enzulu.
Imithombo yeendaba ene-fluoride
I-fluoride-bearing off-gases inokwakheka ngexesha lokwenziwa kwe-phosphoric acid kunye nezichumisi ezixutywe. Ezi gesi ziphuma ngaphandle kufuneka zilahlwe ngenxa yezizathu zokusingqongileyo. I-Sanicro 28 ifanelekile kule njongo. Iimvavanyo zibonise ukuba zikhethwa kakhulu kumabakala aphezulu e-alloyidi e-CrNiMo yokubuyisela igypsum ene-fluoride.
Amaziko amandla enyukliya
Ngenxa yokuchasana kwayo okuphezulu ne-SCC, i-pitting kunye ne-crevice corrosion, i-Sanicro 28 iye yakhethelwa ukutshintshiselana kobushushu kwizityalo zamandla enyukliya.
Amanzi olwandle kunye namanzi okupholisa anekloridi
Ukuchasana kwayo okuphezulu kwi-pitting kunye ne-crevice corrosion yenza i-Sanicro 28 ibe yinto efanelekileyo kakhulu kwimibhobho ephethe amanzi olwandle kunye nokutshintsha kobushushu obupholileyo bamanzi olwandle. Oku kuqinisekiswa ngamava asebenzayo.
I-Sanicro 28 ithathe indawo ye-nickel alloys, i-CuNi, iityhubhu ze-bimetallic kunye ne-coated carbon steel tubes, engazange iphumelele ngenxa ye-corrosion. Ukusebenza kweSanicro 28 kube kuhle kakhulu.
Kumanzi olwandle apholise ubushushu bolwandle kunye nabatshintshisi bobushushu abasebenza ngamanzi okupholisa anekloridi, iSanicro 28 inika ukuxhathisa okuphezulu kokubola kumanzi kunye nendawo epholileyo.
Xa isixhobo sokupholisa amanzi olwandle sivaliwe, akukho mfuneko yokukhupha umbhobho okanye ukugungxulwa ngamanzi amatsha, ngaphandle kokuba ixesha lokuvalwa lifutshane kunenyanga enye kwaye ubushushu bamanzi bungaphantsi kwama-30°C (85°F) .
I-duplex steel stainless 2507 ixhathisa ngaphezu kwe-Sanicro 28 emanzini olwandle.
