Alloy 28isimbi yakakwira-alloy multi-purpose austenitic Stainless simbi yekushandira mumamiriro ekuora zvakanyanya. Grade inoratidzwa ne:
- Yakanyanya kukwirisa corrosion resistance mumaasidhi akasimba
- Yakanyanya kunaka kupikisa kushushikana corrosion cracking (SCC) uye intergranular corrosion munzvimbo dzakasiyana siyana.
- High resistance kune gomba uye crevice corrosion
- Weldability yakanaka

Nekuda kweiyo yakasarudzika corrosion zvivakwa, Sanicro® 28 inogona kushandiswa munzvimbo dzakasiyana siyana. Pazasi pane mienzaniso mishoma yemashandisirwo ayo alloy iyi inonyanya kukodzera.
Phosphoric acid
Nhasi,Alloy 28 kanaSanicro 28 ndiyo inonyanya kushandiswa simbi zvinhu zveevaporator machubhu mukugadzira phosphoric acid nenzira "yakanyorova". Zvikamu zvinoverengeka zvave zvichishanda kweanopfuura makore gumi. Iwo magraphite heat exchangers, akatsiviwa neSanicro 28, aigara aine matambudziko akadzokororwa nemachubhu akatyoka uye kurasikirwa kwekugadzirwa.
Sulfuric acid
Alloy 28 kanaSanicro 28 chinhu chakakodzera chepombi uye chekuchinjana kupisa, kunyanya pamitsetse iri pakati pe40 ne70% ye deaerated acid uye pamusoro pe85%.Alloy 28 kanaSanicro 28 ine inenge yakaenzana yekupikisa seAlloy C mu concentrated acid (98% H2SO4).
Mafuta uye gasi
Alloy 28 kanaSanicro 28 inoshandiswa kugadzira tubing, casing uye liner mumatsime akadzika, anovava gasi. Izvo zvinyorwa zvinokurudzirwawo kune matsime emafuta ane nharaunda inoora. Nezvinangwa izvi, machubhu anopihwa inotonhora yakakungurutswa nesimba rakakura. Mune mhinduro annealed mamiriro,Alloy 28 kanaSanicro 28 inoshandiswawo sepombi yekutakura mafuta ekuora uye gasi uye yekutsinhanisa kupisa munzvimbo dzekurapa. Sanicro 28 waya dzinoshandiswa kudzikisa maturusi uye kudzora zviridzwa mumatsime akadzika emafuta uye gasi.
Fluoride-inobereka media
Fluoride-inobereka-magasi anogona kuumba panguva yekugadzirwa kwephosphoric acid uye mafetireza akasanganiswa. Aya ma-off-gases anofanirwa kuraswa nekuda kwezvikonzero zvezvakatipoteredza. Sanicro 28 yakanakira chinangwa ichi. Miedzo yakaratidza kuti inosarudzika kune yakakwira alloyed CrNiMo mamakisi ekudzoreredza fluoride-inobereka gypsum.
Zvigadzirwa zvemagetsi enyukireya
Nekuda kwekupokana kwayo kwakanyanya kuSCC, gomba uye kukoromoka kwegomba, Sanicro 28 yakasarudzwa kune zvinopisa kupisa mumagetsi enyukireya.
Mvura yegungwa uye chloride-inotonhora mvura inotonhorera
Kupokana kwayo negomba uye kukoromoka kwegomba kunoita kuti Sanicro 28 ive yakanyatsokodzera mapombi anotakura mvura yegungwa uye mvura yegungwa-yakatonhodzwa kupisa. Izvi zvinosimbiswa neruzivo runoshanda.
Sanicro 28 yakatsiva nickel alloys, CuNi, bimetallic chubhu uye yakavharwa kabhoni simbi machubhu, ayo akatadza nekuda kwekuora. Kuita kweSanicro 28 kwave kwakanaka.
Mumvura yegungwa-yakatonhodzwa kupisa kunopisa uye zvinopisa zvinopisa zvinoshanda nemvura inotonhorera ine chloride-inotonhora, Sanicro 28 inopa yakakwira corrosion kuramba kune ese mvura uye yakatonhorera svikiro.
Kana chirimwa chakatonhodzwa nemvura yegungwa chavharwa, hapana chikonzero chekubvisa pombi kana kugezeswa nemvura yakachena, chero nguva yekuvhara iri pfupi kupfuura mwedzi mumwe uye tembiricha yemvura yakadzikira kupfuura 30°C (85°F) .
Iyo duplex Stainless simbi 2507 inoshingirira kupfuura Sanicro 28 mumvura yegungwa.
