I-ASTM A182 S32205 Flanger

Ukuqulunqwa kwekhemikhali ye-Duplex F51 iqulethe i-carbon, iChromium, i-Manganese, Mlybdenum, iNitrogen, iNickel kunye nePhosphorus. Iiflethi zisetyenziswa kwiinkqubo zoxinzelelo kunye ne-veli efanelekileyo.

I-chromium ephezulu, iMolybdenum kunye ne-nitrogen ye-2205 ibonelela ngokuchaseneyo nokunganyangeki okungcono kune-staist engabantu abaqhelekileyo njenge-316l kunye ne-317l kwiindawo ezininzi. Olu lwabiwo olungaqhelekanga lusetyenziswa kwi-oyile kunye negesi kwaye ikwasetyenziswa kwishishini lokuqhubekisa kwamachiza.

Ubume be-2205 intsimbi engenasitali iquka iphuli yephuli ye-austedite ejikelezwe sisigaba esiqhubekayo esiqhubekayo. Kwimeko etyhidiweyo, i-2205 iqulethe malunga ne-40-50% i-ferrite. I-2205 idla ngokubizwa ngokuba yiBanga lokuSebenza kwaye lelona nqanaba lisetyenziswe kakhulu kwi-duppex yenzwane yensimbi.

Kwizicelo ezininzi apho intsimbi engama-300 ye-stainess ithethwe kwi-chloride yoxinzelelo lwe-chloric yoxinzelelo, i-2205 i-duplex engenasitali sisisombululo esisebenzayo. I-Corrosion yoxinzelelo lwe-Corrosion yenzeka xa intsimbi engenazibala iphantsi koxinzelelo olunamathele ngelixa kunxibelelana nezisombululo eziqulathe i-chloride. Amaqondo obushushu aphakamileyo ayonyusa ukonakala kwentsimbi engenasimo kwi-colososion yoxinzelelo.

I-2205 i-Duelplex inamaqhina okwenza ubume benqanaba lesibini le-Ferrite kunye ne-austedite. Xa kufikwa kumba wokuqulunqwa kwamachiza angama-2205 i-dught feles, ubukhulu becala inama-22% chromium, i-3% ye-MOLYBDENUM kunye ne-5-6% ye-nickel ngohlobo lwentsimbi engenasibala.

Kuba i-nickel yinto yorhwebo, iindleko zokusebenzisa izabelo eziye zaza zaza zaza zaza zaza zaza zabelwa ama-alfays ukuba zibize kakhulu. Ngaphandle komxholo we-nickel ophantsi, iDuvex 2200 i-flanges ilawula ukubonisa iipropathi ezininzi ezibalulekileyo ngenxa yomxholo omkhulu we-molybdenum neChromium.

Singomnye wabavelisi abakhulu be-Duepplex Stills ezinamandla amahle kunye nokunganyangeki okuphezulu. I-2205 iDulplex i-Steel Flange i-Flange ikwayaziwa ngezikhundla zayo ezahlukeneyo, ezinje ngokuchaseneyo nokuchasana nokugcuma, kunye nokungakhathali kwiindawo ezinobunzima.

Nangona kunjalo, umxholo wayo kwizitya ze-dupplex zinqongophelelo ngokubanzi ezingaphantsi kwe-4% kuba i-M ikwangumntu ophambili kwaye ungakhokelela kwizigaba ezingafunekiyo. I-Nitrogen iphucula ukumelana nokuzila ukutya kunye neCrevice.

Oku kuthetha ukuba ifumana ukungakhathali kwakhe okuphezulu kunye nokunganyangeki kwe-corosion kwi-Austedite, kunye ne-Werkstoftof No 1.4462 iBlrf Flange inamandla aphezulu kunye nenxalenye ye-Ferrict.

Ikwandisa kakhulu amandla njengesona sicwangciso sisebenzayo someleza into eqinileyo. I-nitrogen ngumntu onamandla omeleleyo, kunye nokongezwa kwe-nitrogen kuphucula kakhulu ubunzima beentsimbi ezimbini. Ikwalibazisa ukumiswa kwemigaqo ye-intermetallic ngokwaneleyo ukuba ivumele ukuqhubekiswa kunye nokutsalwa kweetayile zenqanaba lesibini. I-nickel sisitayile esinyanzelekileyo esikhuthaza ukusekwa kwesakhiwo se-Austititic FCC, esinegalelo kubunzima beentsimbi ezimbini.

Kwi-duplex yentsimbi engenasitali, isisombululo sihlekisa kubushushu obufanelekileyo olandelwa kukuhamba kwamanzi ngokukhawuleza kunokufezekisa i-austellite yenqanaba le-Austerite. Kubalulekile ukugcina ixesha phakathi kokushiya iziko kunye nokucinywa kwamanzi ngokufutshane kangangoko kunokwenzeka. Oku kukunciphisa ilahleko yobushushu kwi-flange, enokukhokelela ekuqulunqweni kwezigaba ezimbi ngaphambi kokucinywa kwamanzi kubushushu begumbi.

Ii-Duplex izitho zizisiweyo zaziswa kwintengiso njengendlela yokujongana neengxaki ezinxulumene noxinzelelo olunxulumene noxinzelelo olubangelwa zizisombululo ze-chlorine. Ukuqulunqwa kwekhemikhali ye-dupplex Flanges nakwi-flenges ngaphantsi kwe-chlorine-inflastion piking. Ezi alloy azibizi kakhulu kune-nickel steels.

I-Chromium ingumntu ophambili, okuthetha ukuba iphakamisa ubume be-BCC. Ikwandisa ukumelana kwe-oxidation kwiqondo lobushushu ephezulu. I-chromium ephezulu ikwakhuthaza ukusekwa kwezigaba ze-intermetallic, ezizonakalisayo kwizistim ezingenazibala kwaye kufuneka ziqwalaselwe.

I-Chromium, iMolybdenum, i-nitrogen kunye ne-nickel yeyona nto ibaluleke kakhulu yolwabiwo, enefuthe elibonakalayo kwi-poples, eyeyasemzimbeni kunye nezonyango lwe-duppex engenasiseko. I-Chromium iyimfuneko ukwenza ifilimu ye-chromium efanelekileyo eyaneleyo yokukhusela intsimbi kwi-themossion ethambileyo. Ukuphakathi komxholo we-chromium, okungcono ukumelana nokungakhathali.

Njengawo onke amabanga angenasitali angenazintlukwano, ukunganyangeki kwengqondo kwentsimbi okanye isabelo kuxhomekeka kubume besinyithi, kule meko inesitayile esingaqhelekanga. Ukuxhathisa kwi-chloride pide yokubeka kunye ne-Crevice yosulelo, umxholo wezinto ezinjengeChromium, iMolybdenum kunye ne-nitrogen ithathwa njengeyona ibaluleke kakhulu.

Kumanqanaba angenasiphelo angenasiseko (njengama-304 nangama-30 ukuya kwengama-306), i-SCC inokuba yingxaki kwiindawo ezinomswakama kunye namaqondo obushushu aphezulu anjenge-chlolor. Ke ngoko, abaxhasi abaziimfama ezingaboniyo bahlala bebanika amashishini anjengeoyile kunye nezamashishini, igesi, amashishini ePetrochemical kunye namashishini ase-Petrochemical kunye neMaline.

Umxholo we-chromium uphakathi kwe-20-28%, yiyo loo nto ingeyisizathu se-S31803 \ / s32205 flonges ufonges ufome ithethwa idlule. Kule nto, indawo yokuhlala eyayisenza impilo ekhuselayo ijikeleze iFlanger ijikeleze iFlanger esenza ukuba ixhathise i-oxidotion.

Kuba iziciko zeDubplex ze-vanplex zine-nickel kunye ne-molybdenum kunye ne-austenam kunezini ezingenasiseko, zidla ngokuxhaphaza okufanayo. Umxholo ongezantsi we-duplex ye-subileX ithetha iindleko eziphantsi. Oku kuyinyani, ngakumbi xa i-alloy gwenxa iphezulu. Kananjalo, ngenxa yesandla esiphakamileyo se-duppex esizinga i-staiels ezingenasiseko xa kuthelekiswa neziqu ezingenasiseko, zihlala zinciphisa ububanzi becandelo. Oku kudityaniswa kunokunciphisa kakhulu iindleko kunye nobunzima be-150 ye-Puimex Flonger Plain Depen Plain Demedions xa kuthelekiswa nezinto kumabanga aphezulu angenanto.

Umsebenzi wesibini weDulex Flenges kukwenza lula abasebenzi abafikelela kwezi nkqubo ukucoca, ukuhlola okanye abaguquli. Ngokubanzi, izicelo ze-duplex yenqwaba ye-duplex ifumaneka kula mashishini alandelayo, ezizezisi, izityalo zekhemikhali, izityalo ze-themicols, i-pumpsing yolwandle, imisebenzi yokwakha, kunye nemikhono ye-pulp. Lo mveliso usebenzisa iinkqubo zokulinganisa ukuhambisa imithombo yeendaba, edla ngokudala uhlobo oluthile loxinzelelo kwiflethi eqhelekileyo.

I-Depex Stals inolwakhiwo oluxubeneyo lwe-cubic emzimbeni (BCC) i-fricrite kunye ne-FCC) i-Austedite. Esona sigaba ngasinye senqanaba lokuqulunqwa kunye nonyango lobushushu okanye imbali yobushushu. Nangona kunjalo, uninzi lwamanqanaba angenasitali alunasomeleleyo ngokubanzi athathelwa ingqalelo ukuba abe nezixa-mali ezilinganayo (amaqhezu amaqhezu) olinganayo no-Austedite.

Sebenzisa i-S31803 ye-dupplex yentsimbi eqinisekisa ukusebenza okuphezulu, ukumelana nokunganyangeki okuphezulu kunye nobomi benkonzo obude. Ngenxa yobuntu obubini bokungasebenzi kakuhle kunye nolusu-magama obuncinci ngokuhambelana nobume obufanayo, iSigaba seSigaba seStile yeStile yeStile yeStonge ye-Forg ilifa iipropathi zezinye zezinto zombini.

Ezona zinto ziphambili ze-chromium kunye ne-nickel, kodwa i-nitrogen, iMolybdenum, nobhedu, i-silicon, i-silicon kunye ne-tungsten inokongezwa ukulawula ibhalansi yesakhiwo. Ukuchasana nokunganyangeki kwe-duplex ye-duplex ifana ne-Austetitic Staines Staines ezineempawu ezifanayo zesabelo.

Amaqondo obushushu amaqondo obushushu aqingqiweyo esigaba esisiqingatha sensimbi ayafana neBanga lama-430 kuluhlu lwamaqondo obushushu angama-950 ukuya kwi-1150¡nc. Nangona kunjalo, amandla e-subile yezi fanxungs anyusa ngokukhawuleza ngaphantsi kwe-900¡ct.

Xa kuthelekiswa nezitho ezi-austetitic ezingenasiseko, ii-duplex ezingenasitali zinezithambisi eziphezulu kunye nezivuno kunye nokuchasana nokumelana nokuchasana nokuchasana kwe-chloride (i-charrosion yoxinzelelo). Babonisa ubunzima obuphezulu kunakwizini ezingenamsebenzi.

Ayingasenzi i-S32205 i-Asmex Steel Asme SA182 I-Weld Weld Flanes ilungele izixhobo zolwandle kunye nezixhobo zokuvelisa amandla, nangona ikwanazo iimpawu ezihambahambayo.
