317, 317L isishintshi sokushisa sensimbi engagqwali
Incazelo yezinto ezibonakalayo
- Incazelo yezinto ezibonakalayo
Insimbi engagqwali ye-austenitic enenani eliphakeme le-chromium, i-nickel kanye ne-molybdenum element enikeza amandla amahle kakhulu okumelana nokugqwala.Inokumelana okuphezulu emiphumeleni yamakhemikhali evela kuma-asidi ahlukene.I-alloy 317L ingukuqukethwe kwekhabhoni ephansi ivumela ukumelana nokugqwala kwe-intergranular.Inamandla aphezulu okuqina emazingeni okushisa aphezulu.Iyakwazi ukushiselwa ngayo yonke inqubo evamile yokushisela futhi ikwazi ukushintshwa kalula ngemishini evamile. - Idatha yokwenziwa
Lezi zisetshenziswa ngokushisa kusetshenziswa yonke inqubo ejwayelekile yokusebenza okushisayo.Ishisiswa emazingeni okushisa aphakathi kuka-1149 kuya ku-1260 degree C. Izinga lokushisa kufanele ligcinwe lingaphansi kuka-927 degree C. Inqubo yokudonsa ngemva komsebenzi ifakwa kuyo ukuze igcine izimfanelo zokumelana nokugqwala okuphezulu.Ngaphezu kwalokho, le nqubo yenziwa ukunciphisa ukucindezeleka kwangaphakathi.Amashubhu e-SS adonswa kalula ngokusebenza okubandayo.Ukwelashwa kokushisa ngeke kuthinte isakhiwo, noma kunjalo, ukusebenza okubandayo okusebenzayo kulandelwa ukuthola izakhiwo eziqinile.
Ukufakwa kwesisombululo kwenziwa emazingeni okushisa aphakathi kuka-1010- 1121 degree C bese kulandelwa ukupholisa.Ingaphansi kwenqubo yokuqedela yezimboni ukuze ithole ubukhulu obunembile kanye nokuqedwa kwendawo. - Ukuphathwa kwekhwalithi
Ithimba lethu lonke lishajwa kabusha ukuze liphakamise ukuzibophezela kwekhwalithi.Amandla ethu abalulekile yiqembu elizinikele neligqugquzelekile.Sizinikele ekuhlinzekeni imikhiqizo namasevisi ekhwalithi ephezulu kumakhasimende.Njengoba singabahlinzeki bomhlaba wonke, silinganisa imikhiqizo yethu ngezindinganiso ezigunyazwe ngamazwe ngamazwe ukuze siqinisekise ikhwalithi yemikhiqizo.Ukuhlolwa kokuqina, ukuhlolwa kwe-thermal conductivity, ukuhlolwa kokuvuza, ukuhlolwa kwezinto ezibonakalayo, ukuhlolwa kwe-intergranular corrosion, nokuhlolwa komshini, ukuhlolwa okunikezwe, kwenziwa yithi esigabeni sokuqala.
Ukuhlolwa kokugcina kwenziwa yiziphathimandla zezinkampani zangaphandle.Ngaphezu kwalokho, ukuhlolwa kwesibili ukuhlolwa okulimazayo, ukuhlolwa kokucindezela, ukuhlolwa kwe-tensile nokunye okuningi.
I-Stainless Steel 317 / 317L Heat Exchanger Tubes iyatholakala ngezinhlobonhlobo zokuqeda, umuntu angazithola kithi.
