Ngokuqhelekileyo, i-VJ Piping yenziwe ngensimbi engenasici kuquka i-304, i-304L, i-316 kunye ne-316Letc. Apha siza kwazisa ngokufutshane iimpawu zezinto ezahlukeneyo zensimbi ezingenasici.
SS304
Ipayipi ye-304 yensimbi engenasici iveliswa ngokuhambelana nomgangatho we-ASTM waseMelika we-brand yensimbi engenasici.
I-304 ipayipi yensimbi engenasici ilingana ne-0Cr19Ni9 (OCr18Ni9) yethu yombhobho wensimbi engenasici.
I-304 ityhubhu yensimbi engenasici njengentsimbi engenasici isetyenziswa kakhulu kwizixhobo zokutya, izixhobo zekhemikhali ngokubanzi, kunye neshishini lamandla e-athomu.
I-304 ipayipi yensimbi engenasici ngumbhobho we-universal steel stainless, isetyenziswa ngokubanzi kwimveliso yokusebenza kakuhle okubanzi (ukumelana nokubola kunye nokubumba) izixhobo kunye neengxenye.
Umbhobho we-304 wensimbi engenasici yeyona ntsimbi isetyenziswa kakhulu, intsimbi ekwazi ukumelana nobushushu. Isetyenziswa kwizixhobo zokuvelisa ukutya, izixhobo zekhemikhali ngokubanzi, amandla enyukliya, njl.
I-304 ye-stainless steel ityhubhu yokwakheka kweekhemikhali inkcazo ye-C, Si, Mn, P, S, Cr, Ni, (Nickel), Mo.
I-Stainless Steel 304 kunye ne-304L umahluko wokuSebenza
I-304L i-corrosion resistant, i-304L iqulethe i-carbon encinci, i-304 yintsimbi ye-universal stainless, kwaye isetyenziswa ngokubanzi kwimveliso yezixhobo kunye neengxenye ezifuna ukusebenza kakuhle okubanzi (ukumelana nokubola kunye nokubumba). I-304L iyintlukwano ye-304 yensimbi engenasici enomxholo ophantsi wekhabhoni kwaye isetyenziselwa ukufakwa kwe-welding. Umxholo ophantsi wekhabhoni unciphisa imvula ye-carbides kwindawo echaphazelekayo ukushisa kufuphi ne-weld, engakhokelela kwi-corrosion ye-intergranular (i-welding erosion) kwinsimbi engenasici kwezinye iindawo.
I-304 isetyenziswa ngokubanzi, ngokuxhathisa okulungileyo kokuhlwa, ukumelana nobushushu, amandla aphantsi obushushu kunye neempawu zoomatshini; Ukusetyenzwa kakuhle kwe-thermal, okufana nokunyathela kunye nokugoba, ngaphandle konyango lobushushu lukhuni umcimbi (akukho magnetic, usebenzisa ubushushu -196℃-800℃).
I-304L inokuxhathisa okugqwesileyo kumda wokutya okuziinkozo emva kwe-welding okanye isiqabu soxinzelelo: inokugcina uxhathiso olululo lwe-corrosion nangaphandle konyango lobushushu, ubushushu bokusebenza -196℃-800℃.
SS316
I-316 insimbi engenasici ineempawu ezintle zokukhukuliseka kwekloridi, ngoko isetyenziswa ngokuqhelekileyo kwiindawo zaseLwandle.
Umzi-mveliso wetyhubhu yentsimbi enganyangekiyo onganyangekiyo
Ukumelana ne-Corrosion kungcono kune-304 yensimbi engenasici, kwinkqubo yokuvelisa i-pulp kunye nephepha inokumelana nokubola okulungileyo.
Kwaye i-316 insimbi engenasici iphinda ixhathise kwi-Marine kunye ne-atmosphere yezoshishino ezinobundlobongela. Ukumelana nobushushu kwii-degrees ze-1600 ngaphantsi kokusetyenziswa okungapheliyo kunye ne-1700 degrees ngaphantsi kokusetyenziswa okuqhubekayo, i-316 insimbi engenasici inokumelana ne-oxidation efanelekileyo.
Kuluhlu lwe-800-1575 degrees, kungcono ukuba ungasebenzisi ngokuqhubekayo i-316 yensimbi engenasici, kodwa kwiqondo lokushisa ngaphandle kokusetyenziswa okuqhubekayo kwe-316 yensimbi engenasici, insimbi engenasici inokumelana nokushisa okulungileyo.
Ukumelana ne-carbide precipitation ye-316 insimbi engenasici ingcono kune-316 yensimbi engenasici kwaye ingasetyenziselwa kwiqondo lokushisa elingentla.
I-316 insimbi engenasici inokusebenza kakuhle kwe-welding. Inokudityaniswa kusetyenziswa zonke iindlela ze-welding eziqhelekileyo. I-Welding ingasetyenziselwa ngokusetyenziswa kwe-316Cb, i-316L okanye i-309CB intonga yokuzalisa insimbi engenasici okanye i-electrode welding. Ukuze ufumane ukuchasana kwe-corrosion engcono kakhulu, icandelo elidibeneyo le-316 yensimbi engenasici iya kuhlanjululwa emva kwe-welding. I-post weld annealing ayifuni ukuba i-316L insimbi engenasici isetyenzisiweyo.
Ukusetyenziswa okuqhelekileyo: izixhobo zepulp kunye nephepha ezitshintshisa ubushushu, izixhobo zokudaya, izixhobo zokuphuhlisa ifilim, imibhobho, kunye nemathiriyeli yomphandle wezakhiwo zasedolophini kwimimandla eselunxwemeni.
Antibacterial Stainless Steel
Ngophuhliso loqoqosho, insimbi engenasici kushishino lokutya, iinkonzo zokutya kunye nokusetyenziswa kobomi bentsapho kubanzi ngakumbi nangakumbi, kuthenjwa ukuba ngaphandle kwentsimbi yentsimbi yempahla yasendlini kunye netafile, eqaqambileyo kwaye icocekile njengeempawu ezintsha, kodwa nayo inezixhobo ezitsha. eyona mildew, antibacterial, umsebenzi wokuvala inzala.
Njengoko sonke sisazi, ezinye isinyithi, ezifana nesilivere, ubhedu, i-bismuth, njalo njalo, zine-antibacterial, i-bactericidal effect, ebizwa ngokuba yi-antibacterial stainless steel steel stainless steel stainless steel stainless steel ukongeza inani elifanelekileyo lezinto ezine-antibacterial effect (ezifana nobhedu). , isilivere), ukuveliswa kwentsimbi emva kokunyanga ubushushu be-antibacterial, kunye nokusebenza okuzinzile kokusebenza kunye nokusebenza kakuhle kwe-antibacterial.
I-Copper iyona nto iphambili ye-antibacterial, ingakanani ukongeza akufanele iqwalasele ipropati ye-antibacterial kuphela, kodwa iphinde iqinisekise iipropati ezintle kunye nezinzile zokucwangcisa isinyithi. Olona bungakanani bobhedu luhluka ngeentlobo zetsimbi. Ukubunjwa kweekhemikhali zetsimbi ye-antibacterial stainless steel ephuhliswe yiJapan Nissin Steel iboniswe kwiThebhile 10. I-1.5% yobhedu yongezwa kwinsimbi ye-ferritic, i-3% kwintsimbi ye-martensitic kunye ne-3.8% kwintsimbi ye-austenitic.
