Intsimbi engenasitayile

Intsimbi engenasitali ibhekisa kwimpahla yakhe ye-Microcrite iqulathe i-Ferrite kunye ne-Austedite, i-Accounting nganye malunga ne-50%. Ngokwenene ukusetyenziswa, kufanelekile ngakumbi kwisigaba esinye sokuba phakathi kwe-40-60%.

According to the characteristics of the two-phase structure, by properly controlling the chemical composition and heat treatment process, the excellent toughness and weldability of austenitic stainless steel are combined with the higher strength and chloride stress corrosion resistance of ferritic stainless steel, making duplex stainless steel a type of steel that combines excellent corrosion resistance, high strength and easy processing and manufacturing. Iipropathi zabo zokwenyama ziphakathi kwentsimbi engenasitayile engenasibala kunye nentsimbi engenasibala, kodwa kufutshane ne-Ferric Fortic Staic kunye nentsimbi yekhabhoni. Ukuxhathisa kwi-chloride pide yokubekwa kunye ne-Crevice yosulelo lwentsimbi engenasibala kunxulumene nomxholo we-chromium, molybdenum kunye nenitrogen. Ukuxhathisa kwayo ekuthandeni nasekuhlaleni i-Crevice kungafana ne-316 yentsimbi, okanye ngaphezulu kwentsimbi engenasibala kumanzi olwandle, njengentsimbi eyi-6% mo os. Zonke izitya ezingenazibala ezingenamanzi zixhaphake kakhulu kwi-chloride yoxinzelelo lwe-chlorion yoxinzelelo kunama-300 eestrititic ezingenasiphelo, kwaye amandla abo aphezulu kakhulu kunamaqhinga afanelekileyo kunye nobunzima.

Iifom zemveliso ezahlukeneyo ze-dupplex ze-duppex: ieplates kunye nemigca yemibhobho ye-Welfs kunye nemibhobho ye-Welfmed kunye nemibhobho ye-Wipe egcwele i-pieds ezigqwesileyo kunye ne-rods

I-Duelplex Intsimbi engenasimo inokuthi yahlulwe yangamacandelo amane:

Inye: Uhlobo olusezantsi, iBanga lokumela I-UNLS32304, intsimbi ayinayo i-molybdenum, i-Pren: 24-25, inokuthatha indawo ye-Aisi 304 okanye i-AISI YOKUGQIBELA I-AISI YOKUGQIBELA.

Zimbini: uhlobo lwesakhiwo esiphakathi, iBanga elimele iBanga le-Anth21803, i-Prerosion: 32-33, ukuxhathisa i-corrosion kuphakathi kwe-Aisi316L kunye ne-6% mobile engenasitayile.

Isithathu: Uhlobo oluphezulu lwe-Alloty, iqulethe i-25% cr, iqulethe i-molybdenum kunye ne-nitrogen, amaBanga asemgangathweni, i-tungsten, i-tungsten, i-Porrosion, i-PROSION.

Ezine: Uhlobo lwentsimbi ebalaseleyo, equkethe i-molybdenum ephezulu kunye ne-witrogen, amabakala asemgangathweni, ezinye, ziqulathe iipropathi eziphakathi nobhedu kunye noomatshini bokulinganisa, ezinokuthelekiswa nentsimbi engenasiseko. (Qaphela: Pren: Ukuphelisa ixabiso elingaphezulu)

Ukuqulunqwa kweekhemikhali izinto eziphambili zentsimbi yensimbi ye-Dulex, Nni, MON NO-NO. Amanqanaba ensimbi ayanezinto ezinje ngeMn, Cu, kunye neW. Cr, Ni, kunye neMo zinokuphucula ukumelana nokunganyangeki. Ukuxhathisa kwayo ekuthambeni nasekuhlaleni i-Crevice Corrosion ilunge kakhulu kwimo ye-chloride.

Izibonelelo ze-Dupplex intsimbi engenasibala

1. Xa kuthelekiswa nentsimbi engenasitayile

1) Isivuno samandla singaphezulu kokuphindwe kabini kwintsimbi engenasiseko esiqhelekileyo, kwaye ineplastikhi eyaneleyo kunye nobunzima obufunekayo bokwakha. Ubungqingqwa beetanki zokugcina okanye iinqanawa zoxinzelelo ezenziwe ngentsimbi engenasibala ngama-30-50% iphantsi kwentsimbi engapheliyo i-austeritic ye-austenitic, elungele ukunciphisa iindleko.

2) Iluxhathisa ngokugcobayo kuxinzelelo lokungahambi kakuhle, ngakumbi kwiindawo ezinendawo equkethe i-chloride ion. Nditsho nentsimbi engenasithuba esingenamandla kunye nomxholo ophantsi we-alloy unenteko ephezulu yokunganyangeki kunesithsaba esingenasibindi. Uxinzelelo I-IRROSIONIONIONIONIONIT yingxaki ebalulekileyo enesibetho esiqhelekileyo esiqhelekileyo esinzima ukusombulula. 3) Ukunganyangeki kwe-corrosion yesona sentsimbi exhaphakileyo engama-2205 esetyenziswa kwimithombo yeendaba ezininzi ilunge ngakumbi kunelo yensimbi ye-Austeritic enesibindi, kunye ne-dustx ebalaseleyo. Kweminye imithombo yeendaba, njenge-acetic acid kunye ne-acid ye-acid, inokubuyisa i-alloitic austeritic austenitic engenasitayile kunye ne-alrosis-i-nears. 4) Inenteko entle yokunganyangeki. Xa kuthelekiswa nentsimbi engenasitali engenasiseko kunye nomxholo ofanayo we-AWORY, inxibe ukunganyangeki kunye nokuchasana nokungakhathali kungcono kunentsimbi engenasiseko engenasicabala. 5) Ukwanda komgangatho olandelwayo kungaphantsi kwentsimbi engenasitayile engenasitayile, kufutshane nentsimbi yekharbon, ilungele ukunxibelelana ne-carbon sension, kwaye ibalulekile kwimveliso yeepleyiti zengxowa-mali okanye njengokuvelisa iipleyiti zengxowa-mali.

2. Xa kuthelekiswa nentsimbi engenasigaba se-freric, izibonelelo zeDellex ezingenazibala zezi zilandelayo:

1) Iipropathi ezibanzi zoomatshini ziphezulu kunezo zentsimbi ezingenamsebenzi, ngakumbi ubunzima beplastiki. Ayithathwa njengoBrittlet njengentsimbi engenasitayile.

2) Ngaphandle kokunganyangeki koxinzelelo lokunganyangeki, enye inkcaso yendawo yokuhlala yalapha ekhaya ilunge ngakumbi kunentsimbi engenasimo sengqondo esingapheliyo.

I-3) Ukusebenza kubanda ngokusebenza kunye nokusebenza okubandayo kokusebenza kungcono kakhulu kunentsimbi engenasitayile.

I-4) Ukusebenza kwe-welding kubhetele kunentsimbi engenasitayile. Ngokubanzi, akukho nto ifunekayo ngaphambi kokuba i-welding kwaye akukho nyango lobushushu luyafuneka emva kwe-welding.

I-5) Uluhlu lwesicelo libanzi kunelo lentsimbi engenasiseko.

Isicelo

Ngenxa yamandla aphezulu ensimbi ye-Deplex, inokugcina izixhobo, njengokunciphisa ubukhulu becala lombhobho. Thatha i-Sase2205 neSaf2507w njengemizekelo. I-SAF2205 ilungele ukusetyenziswa kwiindawo ezinendawo ze-chlorine. Ezi zixhobo zilungele ukucokiswa kweoyile okanye eminye imithombo yeendaba exutywe ne-chlolor. I-SAF2205 ilungele ngokukhethekileyo kubaphesheya obushushu obusebenzisa i-chlorine-enezisombululo ze-actorine ezinamanzi okanye amanzi anetyiwa njengamajelo eendaba ezipholileyo. Esi sixhobo sikwafanelekile kwizisombululo zesalfuric acid kunye ne-acid ecocekileyo ye-acids kunye nemixube yazo. Umzekelo: Imibhobho yeoyile kwi-oyile kunye negesi: Ukuchitheka kweoyile okrwada kwi-windows, i-sulfur-ene-challing yegesi, izixhobo zokuhamba kwamanzi amdaka; Iinkqubo zokupholisa usebenzisa amanzi anetyiwa kancinci okanye i-chlorine eneezisombululo.
