Hastelloy C-276® ndeye nickel-molybdenum-chromium alloy ine yakanakisa corrosion kuramba munzvimbo dzakakomba.Iyo yakakwira nickel uye molybdenum zvirimo zvinoita kuti nickel simbi alloy isanyanya kurwisa gomba uye crevice corrosion mukuderedza nharaunda nepo chromium ichiendesa kuramba kune oxidizing midhiya.Kunyangwe paine misiyano yakati wandei yeHastelloy nickel alloy, Hastelloy C-276 ndiyo inonyanya kushandiswa zvakanyanya.
Mhedziso yeHastelloy C-276 maitiro:
Hastelloy C-276 (N10276) ine yakanakisa corrosion kuramba kune yakawanda inopisa midhiya pasi pe oxidation uye kuderedza mamiriro.Kupokana kwakanakisa kugomba corrosion, crevice corrosion uye stress corrosion kuparuka.Iyo alloy yakakodzera kune akasiyana makemikari process maindasitiri ane oxidizing uye kuderedza midhiya.Iyo yakakwira yemukati yemolybdenum uye chromium inoita kuti alloy irambe yakaora ne chloride ions, uye element tungsten inowedzera kunatsiridza kusaora kwayo.
Hastelloy C-276 ndechimwe chezvishandiso chete zvinogona kurwisa kusvibiswa kwemunyoro chlorine, hypochlorite uye chlorine dioxide mhinduro.Iyo alloy ine kwakakosha kuonda kuramba kunehigh-concentration chlorinated munyu mhinduro (senge chlorinated Iron uye copper chloride).

Hastelloy C276® Applications
Hastelloy C-276 yakashandiswa zvakanyanya mumakemikari uye petrochemical minda, senge muzvikamu uye catalytic masisitimu inobata chloride-ine organics.Nyaya iyi inonyanya kukodzera kushandiswa mukupisa kwepamusoro, yakasanganiswa netsvina ye inorganic uye organic acids (senge formic acid uye acetic acid), uye mvura yegungwa inoparadza nharaunda.
Dzimwe nzvimbo dzekushandisa:
● Indasitiri yepulp nemapepa, zvakadai sokugayiwa kwezvokudya uye midziyo inocheneswa
● Washing tower, reheater, wet steam fan, nezvimwewo muFGD system
● Zvishandiso uye zvikamu zvinoshanda munzvimbo yeasidhi gasi
● Reactor yeacetic acid uye zvigadzirwa zveasidhi
● Sulfuric acid condenser
●Methylene diphenyl isocyanate (MDI)
● Kugadzirwa uye kushandiswa kweasina kuchena phosphoric acid
