I-UNS N08028/EN 1.4563/Ingxubevange 28 yensimbi engagqwali

Ingxubevange 28 amapuleti ensimbi, ingxubevange 28 imigoqo yensimbi engagqwali

Ngokufana ne-Sandvik Sanicro 28, i-alloy 28 iwuhlobo lwe-ultra-low carbon nickel-iron-chromium Austenite alloy enezengezo ze-molybdenum nethusi futhi iyizinga lensimbi engagqwali elinokuqukethwe okuphezulu kwe-nickel. Inokumelana nokugqwala okuhle endaweni ene-asidi eqinile kanye nokumelana nokuqhekeka kokugqwala kwengcindezi endaweni ye-hydrogen sulfide (H2S) kanye ne-chloride. Ngaphezu kwalokho, futhi inokumelana okuhle kakhulu nokugoba, ukuqhekeka, i-intergranular, ukugqwala kwengcindezi nokuqhekeka, kanye nokushisela okuhle. Ngenxa yalezi zakhiwo zokugqwala ezivelele, i-alloy 28 ingasetshenziswa ezindaweni ezihluke kakhulu.

Izicelo:

I-alloy28 ekuqaleni yasungulwa ukuze ixazulule i-wet-process phosphoric acid heat exchanger material. Ukumelana nokugqwala kwayo okuhle kakhulu kuyenza ikwazi ukumelana nokugqwala kwe-H2S, i-chloride, i-phosphoric acid, kanye ne-sulfuric acid corrosion resistance, esetshenziswa kabanzi kokuqukethwe okuphezulu kwe-H2S ekuxhashazweni kwensimu kawoyela negesi, uhlelo lwe-flue gas desulfurization, Amanzi olwandle namanzi okupholisa ane-chloride, imboni yokwenza amaphepha, i-phosphoric acid kanye ne-organic acid kanye nedivayisi yokukhiqiza i-ester synthesis, iyinto ekahle esetshenziselwa ukufaka esikhundleni sokushintshanisa ukushisa kwegraphite ku-phosphoric acid egxilile.

I-LKALLOY ingumnikezeli ohamba phambili embonini wochungechunge lwe-Cr-Ni namanye ama-alloys ensimbi engagqwali ekhwalithi ephezulu. I-LKALLOY ihlinzeka nge-alloy 28 ipayipi neshubhu, induku eyayisetshenziselwa izinhlelo zokusebenza eziningana njengama-condensers, izishintshi zokushisa, izihlungi, nokuningi.
