Ukukhethwa Kwezinto Ze-Flange Zensimbi Engagqwali

Ukukhethwa kwezinto ze-flange zensimbi engagqwali kufanele kusekelwe ekuhlolweni okuphelele kwesimo sokusetshenziswa, indawo egqwalisayo, izinga lokushisa, ingcindezi, nezinye izimo. Nazi izinto ezivamile kanye nezimo zazo ezisebenzayo:

Insimbi Engagqwali engu-304 (06Cr19Ni10)
Izici: Iqukethe i-18% chromium kanye ne-8% nickel, ayikho i-molybdenum, imelana nokugqwala okuvamile, futhi ingabizi kakhulu.
Izimo ezisebenzayo: Izindawo ezomile, ukucubungula ukudla, ukuhlobisa izakhiwo, izindlu zemishini yasekhaya, njll.
Imikhawulo: Ithambekele ekugqwaleni okubangelwa ukugqwala ezindaweni eziqukethe ama-ion e-chloride (isb., amanzi olwandle, amanzi echibini lokubhukuda).

Insimbi Engagqwali engu-316 (06Cr17Ni12Mo2)
Izici: Iqukethe i-molybdenum engu-2.5%, ukumelana okuthuthukisiwe kokugqwala kwe-chloride ion, ukumelana nokushisa okuphezulu (≤649℃).
Izimo ezisebenzayo: Imishini yasolwandle, amapayipi amakhemikhali, amathuluzi ezokwelapha, izindawo ezinokushisa okuphezulu kanye nezindawo ezinomfutho ophezulu.

304L/316L (Izinguqulo ze-Carbon Ephansi)
Izici: Okuqukethwe kwekhabhoni ≤0.03%, ukumelana okuphezulu kokugqwala kwe-intergranular uma kuqhathaniswa nokwejwayelekile okungu-304/316.
Izimo ezisebenzayo: Imishini efakwe ukushiselwa okushisa okuphezulu noma edinga ukumelana nokugqwala isikhathi eside (isb., amandla enuzi, imithi).

Ezinye Izinto Zokusebenza
347 Insimbi Engagqwali (CF8C): Iqukethe i-niobium, efanelekile ezindaweni ezishisa kakhulu (≥540℃).
Insimbi Engagqwali Ephindwe Kabili: Ihlanganisa izakhiwo ze-austenitic neze-ferritic, inamandla aphezulu, ifanelekela izimo zasemanzini ajulile noma ezicindezelayo kakhulu.

Izincomo Zokukhetha
Ukusetshenziswa Okuvamile Kwezimboni: Kuthanda i-304, ishibhile futhi ihlangabezana nezimfuneko eziningi.
Izindawo Ezonakalisayo: Khetha u-316 noma u-316L, i-molybdenum imelana ngempumelelo nokugqwala kwe-chloride ion.
Izindawo Ezikhethekile Zokushisa Okuphezulu/Ezinomfutho Ophakeme: Khetha izinto ezinekhabhoni ephansi noma ezimbili ngokusekelwe ekushiseni okucacisiwe.
