Ipayipi Lensimbi Engagqwali Elingenamthungo Eliyi-316l
Insimbi engagqwali engu-304 iyinto evamile ensimbi engagqwali, enobuningi obungu-7.93 g/cm³; ibizwa nangokuthi insimbi engagqwali engu-18/8 embonini, okusho ukuthi iqukethe i-chromium engaphezu kuka-18% kanye ne-nickel engaphezu kuka-8%; ukumelana nokushisa okuphezulu okungu-800 ℃, ukusebenza kahle kokucubungula, Ukuqina okuphezulu, okusetshenziswa kabanzi embonini kanye nasembonini yokuhlobisa ifenisha kanye nasembonini yokudla kanye nezokwelapha. Kodwa-ke, kufanele kuqashelwe ukuthi uma kuqhathaniswa nensimbi engagqwali evamile engu-304, insimbi engagqwali engu-304 yebanga lokudla inenkomba yokuqukethwe eqinile. Isibonelo, incazelo yamazwe ngamazwe yensimbi engagqwali engu-304 ngokuyisisekelo ingu-18%-20% we-chromium, u-8%-10% we-nickel, kodwa insimbi engagqwali engu-304 yebanga lokudla iqukethe i-chromium engu-18% kanye ne-nickel engu-8%, okuvumela ukuguquguquka ngaphakathi kobubanzi obuthile, futhi kukhawulelwe okuqukethwe kwezinsimbi ezisindayo ezahlukahlukene. Ngamanye amazwi, insimbi engagqwali engu-304 akuyona ngempela insimbi engagqwali engu-304 yebanga lokudla.
Amapayipi angenasici angenasici angamapayipi ensimbi amelana nezinto ezibuthakathaka ezibolayo njengomoya, umusi, namanzi, kanye nezinto ezibolayo ngamakhemikhali ezifana nama-acid, ama-alkali, nosawoti. Aziwa nangokuthi ipayipi lensimbi elingagqwali elimelana ne-asidi.
Ukumelana nokugqwala kwamapayipi angenasici angenasici angenasici kuncike ezintweni ezihlanganisiwe eziqukethwe ensimbini. I-Chromium iyisici esiyisisekelo sokumelana nokugqwala kwensimbi engagqwali. Lapho okuqukethwe kwe-chromium ensimbini kufinyelela cishe ku-12%, i-chromium ixhumana nomoya-mpilo endaweni ehlanganisiwe ukuze yakhe ifilimu encane kakhulu ye-oxide (ifilimu yokuzivumelanisa) ebusweni bensimbi. , Kungavimbela ukugqwala okwengeziwe kwe-matrix yensimbi. Ngaphezu kwe-chromium, izinto ezihlanganisiwe ezivame ukusetshenziswa zamapayipi angenasici angenasici ahlanganisa i-nickel, i-molybdenum, i-titanium, i-niobium, ithusi, i-nitrogen, njll., ukuze kuhlangatshezwane nezidingo zokusetshenziswa okuhlukahlukene kwesakhiwo nokusebenza kwensimbi engagqwali.
Ipayipi elingenasici elingenamthungo liyinsimbi eyindilinga ende engenalutho, esetshenziswa kabanzi kuphethiloli, amakhemikhali, ezokwelapha, ukudla, imboni elula, izinsimbi zomshini kanye neminye imipayipi yezimboni kanye nezingxenye zesakhiwo somshini. Ngaphezu kwalokho, lapho amandla okugoba kanye nokugoba efana, isisindo silula, ngakho-ke lisetshenziswa kabanzi ekwenziweni kwezingxenye zemishini kanye nezakhiwo zobunjiniyela. Livame ukusetshenziswa futhi ukukhiqiza izikhali ezahlukene ezivamile, imiphongolo, amagobolondo, njll.
Inezinyathelo zokukhiqiza ezilandelayo:
a. Ukulungiswa kwensimbi eyindilinga; b. Ukushisa; c. Ukubhoboza okugoqiwe okushisayo; d. Ukunquma ikhanda; e. Ukukhahlela; f. Ukugaya; g. Ukugcoba; h. Ukucubungula ukukhahlela okubandayo; i. Ukususa amafutha; j. Ukwelashwa ngokushisa kwesixazululo; k. Ukuqondisa; l. Ukunquma ithubhu; m. Ukukhahlela; n. Ukuhlolwa komkhiqizo.
