Ngokubanzi, i-VJ Piping yenziwe ngentsimbi engagqwaliyo kuquka i-304, i-304L, i-316 kunye ne-316Letc. Apha siza kwazisa ngokufutshane iimpawu zezinto ezahlukeneyo zentsimbi engagqwaliyo.
SS304
Umbhobho wentsimbi engagqwaliyo engama-304 uveliswa ngokuhambelana nomgangatho waseMelika we-ASTM wophawu lwentsimbi engagqwaliyo.
Umbhobho wentsimbi engagqwaliyo engama-304 ulingana nombhobho wethu wentsimbi engagqwaliyo oyi-0Cr19Ni9 (OCr18Ni9).
Ityhubhu yentsimbi engagqwaliyo engu-304 njengentsimbi engagqwaliyo isetyenziswa kakhulu kwizixhobo zokutya, kwizixhobo zeekhemikhali ngokubanzi, nakwishishini lamandla e-athomu.
Umbhobho wentsimbi engagqwaliyo i-304 ngumbhobho wentsimbi engagqwaliyo osetyenziswa kwihlabathi liphela, usetyenziswa kakhulu ekuveliseni izixhobo kunye neenxalenye zokusebenza kakuhle (ukuchasana nokugqwala kunye nokwenziwa kakuhle).
Umbhobho wentsimbi engagqwaliyo engu-304 yeyona ntsimbi ingagqwaliyo esetyenziswa kakhulu, emelana nobushushu. Isetyenziswa kwizixhobo zokuvelisa ukutya, izixhobo zeekhemikhali ngokubanzi, amandla enyukliya, njl.
Ityhubhu yentsimbi engagqwaliyo engama-304 iinkcukacha zokwakheka kweekhemikhali C, Si, Mn, P, S, Cr, Ni, (Nickel), Mo.
Umahluko wokusebenza kwentsimbi engagqwaliyo engama-304 kunye ne-304L
I-304L iyakwazi ukumelana nokugqwala, i-304L inekhabhoni encinci, i-304 yintsimbi engagqwaliyo esetyenziswa kwihlabathi liphela, kwaye isetyenziswa kakhulu kwimveliso yezixhobo kunye neendawo ezifuna ukusebenza kakuhle (ukuxhathisa ukugqwala kunye nokukwazi ukwakheka). I-304L luhlobo lwentsimbi engagqwaliyo ye-304 enomxholo ophantsi wekhabhoni kwaye isetyenziselwa ukufakelwa i-welding. Umxholo ophantsi wekhabhoni unciphisa imvula ye-carbides kwindawo echaphazeleka bubushushu kufutshane ne-weld, nto leyo enokubangela ukugqwala phakathi kwe-granular (ukukhukuliseka kwe-welding) kwintsimbi engagqwali kwezinye iindawo.
I-304 isetyenziswa kakhulu, inokumelana nokugqwala okuhle, ukumelana nobushushu, amandla aphantsi obushushu kunye neempawu zoomatshini; Ukulungiswa okuhle kobushushu, okufana nokunyathela nokugoba, ngaphandle konyango lobushushu, ukuqina kwento (akukho magnethi, kusetyenziswa ubushushu -196℃ -800℃).
I-304L inokumelana okuhle kakhulu nokugqwala komda weenkozo emva kokuwelda okanye ukunciphisa uxinzelelo: inokugcina ukumelana okuhle nokugqwala nokuba ayinayo unyango lobushushu, ubushushu bokusebenza -196℃ -800℃.
SS316
I-316 stainless steel ikwanazo neempawu ezilungileyo zokukhukuliseka kwe-chloride, ngoko ke isetyenziswa kakhulu kwiindawo zasemanzini.
Umzi-mveliso wetyhubhu yentsimbi engagqwali enganyangekiyo
Ukumelana nokugqwala kungcono kunentsimbi engagqwali engama-304, kwinkqubo yokuvelisa i-pulp nephepha inokumelana nokugqwala okuhle.
Kwaye i-316 stainless steel ikwamelana nemozulu yeMarine kunye neyomoya wemizi-mveliso onamandla. Ukumelana nobushushu kwi-1600 degrees ngaphantsi kokusetyenziswa okungaqhubekiyo kwaye kwi-1700 degrees ngaphantsi kokusetyenziswa okuqhubekayo, i-316 stainless steel inokumelana okuhle kwe-oxidation.
Kwisithuba se-800-1575 degrees, kungcono ukuba ungasebenzisi rhoqo intsimbi engagqwaliyo engama-316, kodwa kuluhlu lobushushu olungaphandle kokusetyenziswa rhoqo kwentsimbi engagqwali engama-316, intsimbi engagqwaliyo inokumelana kakuhle nobushushu.
Ukumelana ne-carbide precipitation yentsimbi engagqwaliyo engama-316 kungcono kunokumelana nentsimbi engagqwali engama-316 kwaye ingasetyenziswa kuluhlu lobushushu olungentla.
Intsimbi engagqwaliyo engu-316 inokusebenza kakuhle kokuwelda. Ingawelda kusetyenziswa zonke iindlela zokuwelda eziqhelekileyo. Ukuwelda kungasetyenziswa ngokwendlela yokusebenzisa intonga yokuzalisa intsimbi engagqwaliyo engu-316Cb, 316L okanye 309CB okanye ukuwelda kwe-electrode. Ukuze kufunyanwe ukuxhathisa okungcono kokugqwala, icandelo eliweldayo lentsimbi engagqwaliyo engu-316 kufuneka lifakwe emva kokuwelda. Ukuwelda emva kokuwelda akufuneki ukuba kusetyenziswa intsimbi engagqwali engu-316L.
Iindlela eziqhelekileyo zokusetyenziswa: izixhobo zokutshintshiselana ubushushu ze-pulp nezephepha, izixhobo zokudaya, izixhobo zokuphuhlisa ifilimu, imibhobho, kunye nezinto zangaphandle kwezakhiwo zasezidolophini kwiindawo ezikunxweme.
Intsimbi Engagqwaliyo Elwa Nentsholongwane
Ngophuhliso lwezoqoqosho, intsimbi engagqwaliyo kwishishini lokutya, iinkonzo zokupheka kunye nokusetyenziswa kobomi bosapho kuyanda, kuthenjwa ukuba ngaphandle kwezitya zasekhaya zentsimbi engagqwaliyo kunye nezitya zetafile, zikhanya kwaye zicocekile njengeempawu ezintsha, kodwa zikwanomsebenzi ongcono kakhulu wokubola, wokulwa neentsholongwane, kunye nomsebenzi wokubulala iintsholongwane.
Njengoko sonke sisazi, ezinye iintsimbi, ezifana nesilivere, ubhedu, i-bismuth njalo njalo zinefuthe lokulwa neentsholongwane, i-bacterial, ebizwa ngokuba yi-antibacterial stainless steel, zikwintsimbi engagqwaliyo ukongeza inani elifanelekileyo lezinto ezinefuthe lokulwa neentsholongwane (ezifana nobhedu, isilivere), ukuveliswa kwentsimbi emva konyango lobushushu lwe-antibacterial, kunye nokusebenza okuzinzileyo kokucubungula kunye nokusebenza kakuhle kwe-antibacterial.
I-Copper yeyona nto iphambili kwi-antibacterial, ukuba kufuneka yongezwe malini akufuneki icinge kuphela ngeempawu ze-antibacterial, kodwa ikwaqinisekise neempawu ezilungileyo nezizinzileyo zokucubungula intsimbi. Ubungakanani obuhle be-copper buyahluka ngokweentlobo zentsimbi. Ukwakheka kweekhemikhali ze-antibacterial stainless steel eziphuhliswe yi-Japanese Nissin Steel kuboniswe kwiTheyibhile 10. I-1.5% ye-copper yongezwa kwi-ferritic steel, i-3% kwi-martensitic steel kunye ne-3.8% kwi-austenitic steel.
