yenza into eqhelekileyo

I-316l intsimbi engenasitali i-Alostitic i-Alousitic ihlala ibizwa ngokuba "njengentsimbi ye-Marine yeBanga elingenasiseko kuba isetyenziswa phantse i-90% yezicelo zaselwandle-kubandakanya ukonakaliswa. Ukongeza kwizinyithi ezinjengentsimbi kunye ne-NCECEL, i-316L iqulethe i-16-18% ye-chromium kunye ne-2-3% molybdenum. Ezi zinto zibalulekile kuba ziphucula ukumelana nokunganyangeki kwe-alloy; I-Chromium isebenzisana ngeoksijini kumanzi olwandle ukwenza umaleko wokukhusela we-chromium oxide, ngelixa iMolybdenum iphucula ukumelana kwesinyithi ekupheliseni isinyithi. Ukongeza, i-316l inomxholo wekhabhoni esezantsi (kungoko ukusetyenziswa kwe "l" ngegama layo), nto leyo enika ukukhuselwa ngcono ngokuzala.

I-Stainess yentsimbi
Kubalulekile ukuba izinto ezisetyenziselwa nayiphi na iprojekthi inezinto ezichanekileyo zoomatshini bokufaka isicelo. Iinkqubo zonyango zobushushu zihlala zisetyenziselwa ukutshintsha iipropathi zoomatshini bezinyithi, kwaye enye yeenkqubo eziqhelekileyo zokuziphatha ubushushu ziqhelekile.

Umxholo wekhabhoni we-254smo uphantsi kakhulu, okuthetha ukuba kukho ingozi encinci kakhulu ye-carbide yomhlaba obangelwa kukufudumeza. Ingaphumelela i-Strasing Countranion Corrosion yovavanyo (i-Strauss yovavanyo lwe-Asstma262 i-odolo e) nasemva kweyure enye yemvakalelo kwi-600-1000¡cãc. Nangona kunjalo, ngenxa ye-allous yentsimbi ephezulu.

Khetha ulwimi
Ukususela nge-254s moiness yentsimbi yimpahla ephezulu yesabelo, inkqubo yokwenza inzima kakhulu. Generally speaking, people can only rely on traditional processes to manufacture this special stainless steel pipe, such as seamless, casting, forging, rolling, etc.

INJONGO YOKUZIPHATHA NGOKUFANELEKILEYO: Ukuphelisa iziphene kwiziphako ezingenanto kunye neemveliso ezigcweleyo, kunye nokulungiselela umbutho wabandayo osebenzayo kunye nonyango lobushushu obulandelayo.

Ubume be-Austitic ye-316 intsimbi engenasibala ibonelela ngobuchule obuhle kakhulu nokuba ngamaqondo obushushu asezantsi.

Ukuziqhelanisa nenkqubo yobushushu yonyango esetyenziselwa ukwenza izinyithi ductile kunye ne-up ductile emva kwenkqubo ye-thermal okanye yoomatshini. Ukwenza ubungakanani obuqhelekileyo kubandakanya ukufudumeza umbatha kwiqondo lokushisa eliphezulu emva koko ukuveza kumdlalo wobushushu ogulayo emva kokufudumeza, ukuvumela ukuba kupholile kubushushu begumbi. Ukufudumeza kunye nokupholisa okucothayo kutshintsha ubukho bentsimbi, ukunciphisa ubunzima bayo kunye nokwandisa ixesha lokungasebenzi.

Elinye inqaku lentsimbi elingenasitali le-304 lento kukuba isinyithi sinamandla obunye kunye nobunzima, obubonwa nokuba imibhobho yendawo iboniswe kwiindawo eziphantsi kweqondo lobushushu.

Intsimbi engenasinqeli i-304 ityhubhu ifumaneka njengokungena emthungo okanye idyile. Imibhobho inokutsalwa njengeetyhubhu ezingenamthungo ukusuka kwi-billle enye okanye i-weldid ukusuka kumtya okanye iphepha. Kukho iindlela ezahlukeneyo ze-welding ezifana nokuxhathisa i-welding yemibhobho emincinci kunye nombane kwi-welding ye-welding yemibhobho yobungakanani obukhulu.

I-Anneng ephakathi kwe-1050 ne-1080 yenziwa emva kokutsala, ilandelwe ngokucingela ngokukhawuleza, ngakumbi ukubuyisela ukumelana nokubuyisa i-slosion, kodwa akukho nyango lobushushu luye krward 316l.

I-Stainis, iDulplex, i-alloy ekhethekileyo, i-Indel, i-monelloy, i-distelloy, i-nitbonified & ye-witboul ne-carbon yentsimbi - i-Zhengzzhou Hiidiel yezixhobo CO., Ltd.

Ukuvezwa okuzinzileyo okanye ixesha elide lohlobo lwe-316l ukuya kwi-800-1500¡inãF (42-816¡ct) kunokuba yingozi. Ukongeza, ukukhululeka koxinzelelo phakathi kwe-100-1500¡it (593-816¡cãc) inokubangela olu hlobo lomvuzo omncinci.

Ngelixa ama-300 eetayile azithandwa kakhulu, azilungele bonke izicelo zokulinganisa inkqubo. Umzekelo, nangona kukho i-comrosion enganyangekiyo, iindlela ezingama-300 zenze kakuhle phambi kuka-Chlolor. Kwezi meko, amantshontsho anemixholo ephezulu yesabelo eninzi efana ne-molybdenum, iChromium kunye ne-nickel ikhethiwe.

Uhlobo lwe-316 lungamelanga ngakumbi kwizisombululo ze-sulfuric acid kunalo naluphi na olunye uhlobo lwe-chromium-nickel. Uhlobo lwe-316 aluchasanga kwi-Acid uxinzelelo ukuya kuthi ga kwi-5% kumaqondo obushushu ukuya kwi-120¡nãf (49¡c). Olu hlobo luyeyona nto ichasene nokugxininisa kakhulu kubushushu obuphantsi kobushushu obungaphantsi kwe-100¡ F (38¡ c).

Ngokubanzi, uhlobo lwe-316 ibakala linokuqwalaselwa ngokulinganayo kwimeko enikiweyo. Ukukhupha okungathethekiyo kukungabikho kobuntu kwindawo echaphazelekayo kubushushu kwizilwanyana ze-welds kunye ne-AlcetivedAls Alteys kwiindawo ezinendawo ezaneleyo. Kwimithombo yeendaba, uhlobo lwe-316l lilungele iimeko ze-welding kunohlobo lwe-316 kuba umxholo wekhabhoni ophantsi wonyusa ukunyangwa kokungakhathali.

Chwetheza i-316 Alloty ithathwa njengefanelekileyo kwenye indalo esingqongileyo, ezinjengeenqanawa zenqanawa kunye nezixhobo zokugcina izakhiwo ezivela kwi-push yetyuwa. Chwetheza intsimbi ye-316 ibonisa intsimbi engaboniyo ukuba akukho bungqina bokungabikho kwi-100 yeeyure, i-5% yokutshiza (i-ASTM-B-117) kuvavanyo.

I-SA312 i-TP304 iqinisekisiwe ukuba ibe yinto eguquguqukayo enokusetyenziswa kwimizi-mveliso eyahlukeneyo. I-AFALY IBAKALA 304 I-Stainess yentsimbi ye-304 ithandwa ngenxa yokunganyangeki kweyona mithombo yeendaba ezahlukeneyo.

I-Austetitic Stails Staielsceles ichaphazeleka kwi-CROSION CROSION CROSIONS (SCC) kwiindawo zokuhlala. Nangona uhlobo lwe-316 izabelo luxhathisa kakhulu kwi-SCC ngaphezu kwe-18CR-8 NI AFALYs ngenxa yomxholo wawo weMOLBDENUM, usachaphazeleka. Iimeko ezivelisa i-SCC zezi: (1) Ubukho be-halide i-ions (i-chloride ion), (2) yoxinzelelo lwentsalela, kunye (3) nobushushu obungaphezulu kwe-120¡n (49¡c).

Ukuziqhelanisa okuqhelekileyo kusetyenziswa ikakhulu ukuba kubonakale ubume be-carbon yentsimbi kunye nentsimbi ephantsi yentsimbi emva kokukrola, ukuqengqeleka okanye ukuphosa. Ubunzima obufunyenwe emva kokuzimisela okuqhelekileyo kuxhomekeke kuhlalutyo lwentsimbi kunye nenqanaba lokupholisa elisetyenzisiweyo (malunga ne-100-250 hb).

Intsimbi engama-316 ingenalo inyibilikayo; Ayisiyo nje kuphela ipropathi eyomeleleyo kunye newelding, kodwa ikwanamandla okusonga okanye i-crimp, ukuze iguqulwe ngokulula kwizicelo ezahlukeneyo.

I-austitic ye-austetitic ye-austetitic inomdla wokuqhekeka ngexesha le-welding. Ngesi sizathu, uhlobo lwe-316 kwaye luchwethe i-3166 i-Show "

I-316l ityhefu yentsimbi engenasithulo isetyenziselwa ukusetyenziswa kwezicelo ezichanekileyo. I-Parbimation encinci ngexesha le-pipeline ye-welding inciphisa ukuvela kwe-infrasion kunye nokususwa kwendawo. I-tubs ezingenamthungo zivela? " ukuya kwi-16 ".

Ukwenza indalo yenzelwe ukunika intsimbi i-iyunifomu kunye ne-of elungileyo. Le nkqubo isetyenziselwa ukufumana i-Microsctal enokuqikelelwa kunye nokuqinisekiswa kweepropathi zoomatshini bensimbi.

Ngokungafaniyo nezinye iintlobo zentsimbi ezinjengama-304 ne-306, i-316l i-316l alloy yensimbi inokusetyenziswa kwizicelo ezahlukeneyo apho kuyafuneka khona ukumelana nokunganyangeki. Umzekelo, iingcali kumashishini eekhemikhali kunye namayeza echiza ziyisebenzisa ukwenza izixhobo zoqhaqho kunye neendawo zonyango.

Ibanga lama-316ti liqulethe inani elincinci le-titanium. Umxholo wesitatium uhlala ujikeleze i-0.5%. I-titanium inza i-316 kumaqondo obushushu angaphezulu kwe-800¡ct.

Kwimeko yobushushu obuphezulu, intsimbi engama-316 i-stain idla ngokuphuma ngaphandle 304.

Umxholo ophezulu we-molybdenum we-254smo yentsimbi yenza ukuba ibe nenqanaba eliphezulu le-oxidation xa kungeniswe umphezulu wengqolowa emva kokuthathwa kwentsimbi eqhelekileyo. Nangona kunjalo, oku akunasiphumo esibi kwi-corrosion yentsimbi yentsimbi.

Inkqubo yonyango lobushushu apho intsimbi ifuduselwe khona kubushushu obufanelekileyo (ngaphezulu okanye ngaphantsi kwe-AC 1), igcinwe ixesha elithile, kwaye ipholile ngokuthe chu ukufumana i-aquilibrium State.

Injongo yonyango lobushushu bokulungiselela kukuphucula ukupasa, ukuphelisa uxinzelelo lwangaphakathi kwaye ulungiselele ubume obulungileyo besinyithi sonyango lokugqibela. Inkqubo yonyango lobushushu ibandakanya ukungqubana, okuqhelekileyo, ukwaluphala, ukucokisa kunye nokuthengiswa, njl njl.

254SMO esenziwe ngoxinzelelo oluphezulu lwe-molybdenum, iChromium kunye ne-nitrogen inokunganyangeki okuhle ekuthandeni nasekususelweni. Ubhedu luphucula ukumelana nokunganyangeki kwii-asidi ezithile. Ukongeza, i-254smo ineendlela ezifanelekileyo zoxinzelelo lwezinto ezinqabileyo ngenxa yomxholo omkhulu weNickel, Chromium kunye ne-molybdenum.
