Ingxubevange 28iyingxubevange ephezulu ye-multi-purpose austenitic insimbi engagqwali ukuze isetshenziswe ezimeni ezigqwalile kakhulu. Ibanga libonakala ngokuthi:
- Ukumelana nokugqwala okuphezulu kakhulu kuma-asidi aqinile
- Ukumelana okuhle kakhulu nokuqhekeka kwe-corrosion (SCC) kanye nokugqwala kwe-intergranular ezindaweni ezahlukahlukene.
- Ukumelana okuphezulu nokugqwala nokugqwala kwemifantu
- Ukushisela okuhle

Ngenxa yezakhiwo zayo zokugqwala ezivelele, i-Sanicro® 28 ingasetshenziswa ezindaweni ezihluke kakhulu. Uhlu olungezansi kunezibonelo ezimbalwa zezinhlelo zokusebenza lapho le ngxube ifaneleka ngokukhethekile.
I-Phosphoric acid
Namuhla,Ingxubevange 28 nomaI-Sanicro 28 iyinsimbi esetshenziswa kakhulu kunazo zonke kumashubhu e-evaporator ekwenzeni i-phosphoric acid ngendlela “emanzi”. Amayunithi amaningana manje asebenze iminyaka engaphezu kwe-10. Izishintshi zokushisa ze-graphite, ezithathelwe indawo yi-Sanicro 28, zazivame ukuba nezinkinga eziphindaphindiwe ngamashubhu aphukile nokulahlekelwa ukukhiqizwa.
I-sulfuric acid
Ingxubevange 28 nomaI-Sanicro 28 iyimpahla efanelekile yamapayipi kanye nezishintshisi zokushisa, ikakhulukazi lapho kugxilwe phakathi kuka-40 no-70% we-asidi enciphile nangaphezulu kuka-85%.Ingxubevange 28 nomaI-Sanicro 28 inokumelana cishe okufanayo ne-Alloy C ku-asidi egxilile (98% H2SO4).
Amafutha negesi
Ingxubevange 28 nomaI-Sanicro 28 isetshenziselwa ukukhiqiza amashubhu, i-casing kanye nama-liner emithonjeni ejulile, emuncu yegesi. Impahla ibuye ituswe emithonjeni kawoyela enendawo egqwalile. Ngenxa yalezi zinhloso, amashubhu anikezwa abandayo esongwe ngamandla aphezulu. Esimeni sesixazululo esifakiwe,Ingxubevange 28 nomaI-Sanicro 28 iphinde isetshenziswe njengamapayipi okuthutha uwoyela negesi agqwalile kanye nezishintshisi zokushisa ezindaweni zokwelapha. Izintambo ze-Sanicro 28 zisetshenziselwa ukwehlisa amathuluzi kanye nezinsimbi zokulawula emithonjeni ejulile kawoyela negesi.
Imithombo ye-Fluoride
I-Fluoride-bearing off-gases ingakheka ngesikhathi sokwenziwa kwe-phosphoric acid kanye nomanyolo oxubile. Lawa ma-off-gases kumele alahlwe ngezizathu zemvelo. I-Sanicro 28 ilungele le njongo. Ukuhlolwa kubonise ukuthi kungcono kunamamaki e-CrNiMo ahlanganisiwe aphezulu ukuze kutholakale igypsum ene-fluoride.
Izitshalo zamandla enuzi
Ngenxa yokumelana kwayo okuphezulu ne-SCC, ukugqwala kwe-pitting kanye ne-crevice, i-Sanicro 28 ikhethelwe izishintshisi zokushisa ezitshalweni zamandla enuzi.
Amanzi okupholisa amanzi olwandle nane-chloride
Ukumelana kwayo okuphezulu nokugqwala nokugqwala kwenza i-Sanicro 28 ibe into efaneleke kakhulu yamapayipi aphethe amanzi olwandle kanye nezishintshisi zokushisa ezipholiswe ngamanzi olwandle. Lokhu kufakazelwa okuhlangenwe nakho okungokoqobo.
I-Sanicro 28 ithathe indawo ye-nickel alloys, i-CuNi, amashubhu e-bimetallic kanye namashubhu ensimbi e-carbon steel, ahlulekile ngenxa yokugqwala. Ukusebenza kwe-Sanicro 28 kube kuhle kakhulu.
Ezishintshisani zokushisa ezipholile emanzini olwandle nezishintshisi zokushisa ezisebenza ngamanzi okupholisa ane-chloride, i-Sanicro 28 inikezela ukumelana nokugqwala okuphezulu kuwo womabili amanzi nendawo epholile.
Lapho isitshalo esipholiswa ngamanzi olwandle sivalwa, asikho isidingo sokudonsa amapayipi amanzi noma ukushaywa ngamanzi ahlanzekile, inqobo nje uma isikhathi sokuvala sifushane kunenyanga eyodwa futhi izinga lokushisa lamanzi lingaphansi kuka-30°C (85°F) .
I-duplex insimbi engagqwali engu-2507 imelana kakhulu kune-Sanicro 28 emanzini olwandle.
