I-904L|N08904 Ingxube Yensimbi Yensimbi
Incazelo emfushane:
I-904L austenitic insimbi engagqwali ingeyekhabhoni ephansi, i-nickel ephezulu, i-molybdenum austenitic insimbi engagqwali enokumelana ne-asidi.I-904L i-austenitic stainless steel inekhono elihle kakhulu lokuguqula i-activation passivation, ukumelana nokugqwala okuhle kakhulu, ukumelana nokugqwala okuhle kuma-acids angenayo i-oxidizing njenge-sulfuric acid, i-acetic acid, i-formic acid, ne-phosphoric acid, ukumelana kahle nokugqwala kwe-pitting corrosion ku-neutral chloride ion media, futhi kuhle. ukumelana nokugqwala kwemifantu kanye nokugqwala kwengcindezi.Ifanele ukugxiliswa okuhlukahlukene kwe-sulfuric acid ngaphansi kuka-70 ℃, inokumelana nokugqwala okuhle kunoma yikuphi ukugxila kanye nezinga lokushisa le-acetic acid kanye nengxube ye-formic acid ne-acetic acid ngaphansi kwengcindezi evamile.
I-904L iwukuqukethwe kwekhabhoni ephansi, insimbi engagqwali ephezulu ye-austenitic edizayinelwe izindawo ezigqwalayo.Inokumelana nokugqwala okungcono kuno-316L no-317L, kuyilapho ibhalansisa intengo nokusebenza, futhi inezindleko eziphakeme eziphezulu.Ngenxa yokwengezwa kwethusi elingu-1.5%, inokumelana nokugqwala okuhle kakhulu kokunciphisa ama-asidi afana ne-sulfuric acid ne-phosphoric acid.Iphinde ibe nokugqwala okuhle kakhulu kokumelana nokugqwala kwengcindezi, ukugqwala kwe-pitting, nokugqwala kwe-crevice okubangelwa ama-ion e-chloride, futhi inokumelana kahle nokugqwala kwe-intergranular.Ku-asidi ye-sulfuric ehlanzekile enebanga lokuhlushwa lika-0-98%, izinga lokushisa lokusetshenziswa lika-904L lingafinyelela ku-40 degrees Celsius.Ku-asidi ye-phosphoric ehlanzekile enebanga lokuhlushwa lika-0-85%, ukumelana nokugqwala kwayo kuhle kakhulu.Ukungcola kunomthelela onamandla ekuphikisweni kokugqwala kwe-industrial phosphoric acid ekhiqizwa ubuchwepheshe benqubo emanzi.Kuzo zonke izinhlobo ze-phosphoric acid, i-904L inokumelana nokugqwala okungcono kunensimbi engagqwali evamile.Ku-nitric acid ene-oxidizing kakhulu, i-904L inokumelana nokugqwala okuphansi uma kuqhathaniswa namabanga aphezulu ensimbi enengxubevange ngaphandle kwe-molybdenum.Ku-hydrochloric acid, ukusetshenziswa kwe-904L kunqunyelwe ekugxilweni okuphansi kwe-1-2%.Ngaphakathi kwalolu hlu lokuhlushwa.Ukumelana nokugqwala kwe-904L kungcono kunokwensimbi evamile engagqwali.Insimbi engu-904L inokumelana okuphezulu nokugqwala kwe-pitting.Ukumelana kwayo nokugqwala kwe-crevice kusixazululo se-chloride.Amandla nawo mahle kakhulu.Okuqukethwe kwe-nickel ephezulu okungu-904L kunciphisa izinga lokugqwala emigodini nasemifantwini.Insimbi engagqwali evamile ye-austenitic ingase ibe nomuzwa wokubola kwengcindezi endaweni ecebile nge-chloride emazingeni okushisa angaphezu kuka-60 degrees Celsius.Ngokwandisa okuqukethwe kwe-nickel yensimbi engagqwali, lokhu kuzwela kungancishiswa.Ngenxa yokuqukethwe kwayo okuphezulu kwe-nickel, i-904L ibonisa ukumelana okuphezulu nokucindezeleka kokugqwala kokuqhekeka kuzixazululo ze-chloride, izixazululo ze-hydroxide ezigxilile, kanye nezindawo ezicebile nge-hydrogen sulfide.
Imishini ye-petroleum ne-petrochemical, njengama-reactors emishini ye-petrochemical, isitoreji kanye nemishini yokuthutha ye-sulfuric acid, njengama-exchangers okushisa, i-power plant flue gas desulfurization amadivaysi, ikakhulukazi asetshenziswa emzimbeni wombhoshongo, i-flue, amaphaneli eminyango, izingxenye zangaphakathi, izinhlelo zokufutha, njll. wemibhoshongo yokumuncwa, izihlikihli kanye namafeni ezinhlelweni zokwelashwa kwe-asidi ephilayo, izinto zokuhlanza amanzi olwandle, izishintshisi zokushisa kwamanzi olwandle, okokusebenza kwemboni yephepha, i-sulfuric acid kanye nemishini ye-nitric acid, ukukhiqizwa kwe-asidi, njll Imboni yezemithi nezinye izinto zamakhemikhali, imikhumbi yokucindezela, imishini yokudla. , amafekthri ezenza imithi: ama-centrifuge, ama-reactors, njll., ukudla kwezitshalo: amathangi esoso yesosi, iwayini lokupheka, amathangi kasawoti, izinto zokusebenza nezingubo zokugqoka, i-904L iyizinga lensimbi elihambisanayo le-dilute sulfuric acid eqinile egqwalisayo.
Ipuleti, umucu, ibha, ucingo, ukubumba, induku ebushelelezi, impahla yokushisela, i-flange, njll., ingacutshungulwa ngokuya ngomdwebo
