Ngokuvamile, i-VJ Piping yenziwe ngensimbi engagqwali okuhlanganisa i-304, 304L, 316 kanye ne-316Letc. Lapha sizokwethula kafushane izici zezinto ezihlukahlukene zensimbi engagqwali.
I-SS304
Ipayipi yensimbi engagqwali engu-304 ikhiqizwa ngokuhambisana nezinga le-ASTM laseMelika lohlobo lwensimbi engagqwali.
Ipayipi lensimbi engagqwali engu-304 lilingana nepayipi lethu lensimbi engagqwali elingu-0Cr19Ni9 (OCr18Ni9).
304 ithubhu lensimbi engagqwali njengensimbi engagqwali isetshenziswa kakhulu ezintweni zokudla, okokusebenza kwamakhemikhali okujwayelekile, kanye nemboni yamandla e-athomu.
Ipayipi lensimbi engagqwali engu-304 liyipayipi lensimbi engagqwali yendawo yonke, lisetshenziswa kabanzi ekukhiqizeni ukusebenza okuhle okuphelele (ukumelana nokugqwala nokubumba) imishini nezingxenye.
304 insimbi engagqwali ipayipi insimbi engagqwali esetshenziswa kabanzi, insimbi ukumelana nokushisa. Isetshenziswa emishinini yokukhiqiza ukudla, amakhemikhali ajwayelekile, amandla enuzi, njll.
304 ishubhu yensimbi engagqwali imininingwane yokwakheka kwamakhemikhali C, Si, Mn, P, S, Cr, Ni, (Nickel), Mo.
I-Stainless Steel 304 kanye Nomehluko Wokusebenza we-304L
I-304L ikwazi ukumelana nokugqwala, i-304L iqukethe ikhabhoni encane, i-304 iyinsimbi engagqwali yendawo yonke, futhi isetshenziswa kabanzi ekukhiqizeni amathuluzi nezingxenye ezidinga ukusebenza okuhle okuphelele (ukumelana nokubola nokubumba). I-304L iwuhlobo lwensimbi engagqwali engu-304 enokuqukethwe kwekhabhoni ephansi futhi isetshenziselwa izinhlelo zokushisela. Okuqukethwe kwekhabhoni ephansi kunciphisa imvula ye-carbides endaweni ethinteke ukushisa eduze nendawo yokushisela, okungaholela ekugqwaleni kwe-intergranular (ukuguguleka kwe-welding) kunsimbi engagqwali kwezinye izindawo.
I-304 isetshenziswa kabanzi, inokumelana nokugqwala okuhle, ukumelana nokushisa, amandla okushisa aphansi kanye nezakhiwo zemishini; Ukucutshungulwa okuhle kokushisa, njengokunyathela nokugoba, ngaphandle kwesenzo sokuqina sokwelashwa kokushisa (akukho kazibuthe, kusetshenziswa izinga lokushisa -196℃-800℃).
I-304L inokumelana okuhle kakhulu nokugqwala komngcele wokusanhlamvu ngemuva kokushisela noma ukukhululeka kwengcindezi: ingagcina ukumelana nokugqwala okuhle noma ngaphandle kokwelashwa kokushisa, izinga lokushisa lokusebenza -196℃-800℃.
I-SS316
I-316 insimbi engagqwali nayo inezindawo ezinhle zokuguguleka kwe-chloride, ngakho isetshenziswa kakhulu ezindaweni zasolwandle.
Ifektri yeshubhu yensimbi engagqwali engagqwali
Ukumelana nokugqwala kungcono kunensimbi engagqwali engama-304, inqubo yokukhiqiza i-pulp nephepha inokumelana nokugqwala okuhle.
Futhi insimbi engagqwali engu-316 iphinde imelane ne-Marine kanye nomkhathi wezimboni ezinolaka. Ukumelana nokushisa ngamadigri angu-1600 ngaphansi kokusetshenziswa okungapheli futhi kumadigri angu-1700 ngaphansi kokusetshenziswa okuqhubekayo, insimbi engagqwali engu-316 inokumelana okuhle kwe-oxidation.
Ebangeni lama-800-1575 degrees, kungcono ukuthi ungasebenzisi ngokuqhubekayo insimbi engagqwali engu-316, kodwa ebangeni lokushisa ngaphandle kokusetshenziswa okuqhubekayo kwensimbi engagqwali engu-316, insimbi engagqwali inokumelana nokushisa okuhle.
I-carbide precipitation resistance ye-316 insimbi engagqwali ingcono kunaleyo yensimbi engagqwali engu-316 futhi ingasetshenziswa ebangeni lokushisa elingenhla.
I-316 insimbi engagqwali inokusebenza okuhle kokushisela. Kungenziwa ashiselwe usebenzisa zonke izindlela zokushisela ezijwayelekile. Ukushisela kungasetshenziswa ngokuya ngokusetshenziswa kwe-316Cb, 316L noma 309CB insimbi yokugcwalisa insimbi engenasici noma i-electrode welding. Ukuze uthole ukumelana okungcono kakhulu kokugqwala, ingxenye eshiselwe yensimbi engagqwali engu-316 izofakwa ngemuva kokushisela. I-post weld annealing ayidingeki uma kusetshenziswa insimbi engagqwali engu-316L.
Ukusetshenziswa okujwayelekile: izinto zokushintsha ukushisa ze-pulp nephepha, okokusebenza kokudaya, okokukhiqiza ifilimu, amapayipi, nezinto ezisetshenziswa ngaphandle kwezakhiwo zasemadolobheni ezindaweni ezisogwini.
I-Antibacterial Stainless Steel
Ngokuthuthuka komnotho, insimbi engagqwali embonini yokudla, izinsiza zokudla kanye nokusetshenziswa kwempilo yomndeni kuya ngokuya kuyanda, kuthenjwa ukuthi ngaphandle kwezitsha zensimbi engagqwali nezitsha zetafula, ezikhanyayo nezihlanzekile njengezici ezintsha, kodwa futhi isikhutha best, antibacterial, umsebenzi inzalo.
Njengoba sonke sazi, ezinye izinsimbi, njengesiliva, ithusi, i-bismuth nokunye kune-antibacterial, bactericidal effect, okuthiwa i-antibacterial stainless steel, isensimbi engagqwali ukwengeza inani elifanele lezinto ezinomphumela we-antibacterial (njengethusi. , isiliva), ukukhiqizwa kwensimbi ngemva kokwelashwa kokushisa kwe-antibacterial, ngokusebenza okuzinzile kokucubungula nokusebenza okuhle kwe-antibacterial.
I-Copper iyisici esiyinhloko se-antibacterial, ukuthi kungakanani okufakwayo akufanele kucabangele impahla ye-antibacterial kuphela, kodwa futhi kuqinisekise izakhiwo ezinhle nezizinzile zokucubungula zensimbi. Inani elikhulu lethusi liyahlukahluka ngezinhlobo zensimbi. Ukwakheka kwamakhemikhali ensimbi engagqwali elwa namagciwane eyakhiwe yi-Japanese Nissin Steel kukhonjiswe kuThebula 10. I-1.5% yethusi yengezwa ensimbi ye-ferritic, 3% iye kunsimbi ye-martensitic kanye no-3.8% kunsimbi ye-austenitic.
