Isibonelelo sesakhiwo sesibini kukuba sidibanisa izibonelelo ze-ferricus (ukuchasana nokungabinamali kunye nezibonelelo ze-Austentitic Alloys (lula ukumelana nokunganyangeki kwemveliso kunye nokunganyangeki. Iqondo lokushisa lenkonzo le-2205 intsimbi engenasibala kufuneka lilinganiselwe kwi-600¡n. Ukuboniswa ixesha elide kubushushu obuphakamileyo kunokwenza i-2205 yentsimbi engenasitayile.
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.
Ngenxa yomxholo ophezulu wayo kule ntsimbi ingenasitali engaqhelekanga, eli nqanaba likwabizwa ngokuba yi-22 i-CREX ye-CREX. I-Duelplex Stainess yentsimbi ye-flange ye-2205 flanger yelona nani lisetyenziswa kakhulu ngamanqanaba ensizi engenasitali. Inqaku eliqhelekileyo le-22 crplex yentsimbi yentsimbi ye-SEE ye-faeves i-slevents yindlala ephezulu yendalo. Ngapha koko, amandla e-thensen elibakala elikhethekileyo lihlala liphindwe kabini okanye liphindwe kabini kwamabakala angenasiseko.
Uluvo olusisiseko lwe-SEIB yentsimbi ye-Butt ye-Windel Shonges kukuvelisa ubume bekhemikhali owenza umxube olinganayo we-ferite kunye ne-austedite. Ukuqulunqwa kwekhemikhali ye-dupplex i-facks ilungelelene ukuvelisa izixa ezilinganayo zeFerrite kunye ne-Austedite phantsi kwesisombululo.
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.
Njengesithsaba esiphakathi, i-duppex saphakamisa ubuso obucacileyo bokuchasana nokunganyangeki kwamatshini othengiswayo kwi-Austisic Ests yentsimbi ye-ASTM ye-ASTM ye-ASTM ye-ASTM ye-ASTM.
I-Dial-Stage yentsimbi yentsimbi iphakanyisiwe ubuso bubonisa ubuso obugqwesileyo kunye nokungaguqukiyo kokunyusa isantya sokunciphisa isantya, ukunciphisa isixhobo kunye nexesha lokuseta.
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.
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.
Umzimba wesiseko we-Din 1.4462 i-flange inesisa se-ferric kunye ne-austitic. Ubungakanani bemigangatho yabo yoLwimi lungekho kuphela kwiipropathi zoomatshini kodwa nakwiipropathi zabo zokuchasana nezihobuso. Ukwenziwa kweekhemikhali zeS31803 i-sheeke ye-Weld ye-Weld iqulethe i-22% ye-chromium, i-3% ye-molybdenum, kunye ne-5% ukuya kwi-6% i-6% i-Nickel.
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.
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.
Ansi B16.5 I-DEPLEX kunye ne-duppex yensimbi yensimbi, i-ASTM A182, FFNEs, Fufxes, i-FFEANS, FFE, FFE, TF ubuso - Zhengzhou Huitong Pidieline Izixhobo CO., Ltd.
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.
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, 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.
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-Dupex 2205 yi-nitrogen ephuculweyo ye-dupplex engabekwanga ukusombulula iingxaki eziqhelekileyo ukudibana ne-300 izigaba ezingenazitapile. "I-DUPHEX" ichaza usapho lwezitho ngezigadi ezingathandekiyo (ezinje ngentsimbi engama-304) okanye i-304 yentsimbi) okanye i-ferrictic engacocekanga (njengentsimbi engama-430).
Ukuqulunqwa kwezigaba ze-intetmetallic ezinje ngeSigaba se-Sugma kwi-Deplex Flanges ye-600¡c -cle-i-1000¡c yenzekile kuluhlu lobushushu lwe-350¡ct-ããncle (475¡clection).
I-Depex I-Stainess yentsimbi isetyenziswa ngokubanzi kwi-oyile yeoyile ye-oyile kunye negesi apho bavezwa kwimithombo yeendaba. Kwishishini leoyile negesi, apho imithombo yeendaba ithuthwa ngokukhawuleza kwimijelo, amacandelo asetyenzisiweyo apha anokunxiba.
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.
Banceda ukuguqula kwaye bacoceke ezi nkqubo zenkqubo. Ukuchasana nokungaxhathisi kunye neentembeko ze-velex ze-duplex sutel i-aaved ithelekiswa neyona nto iphambili kwentsimbi.
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.
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.
I-Deplex Stouble Steel evuthayo i-flenges yobuso inomthombo wobuchule obuphezulu kwi-chloride-enemidiya, kubandakanya amanqanaba olwandle, esenza le nqanaba ilungele imithombo yolwandle i-onfilical kunye nezicelo zezinye ioyile kunye nezicelo zerhasi.
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.
Ukongeza, i-2205 iflenes yentsimbi ibonakalisa amandla amahle kunye nokuxhathisa ngokugcobayo kwi-chloride yoxinzelelo. Iipropathi ezongezelelweyo zeDulex ezingama-2200 zibandakanya ukumelana ngokugqwesileyo kwi-Crevice yosulelo, ukubeka i-corrosion, ukususwa kwe-erosion kunye nokususwa kwe-erosion kunye nokususwa ngokubanzi kwendawo engqongqo.
I-MolybDenum yonyusa ukumelana nokuzila kunye ne-ravice yosulelo. 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.
Xa kuthelekiswa neziphene ezihambelana ne-austeritic, zihambelana kakhulu kukuphathwa kwezigaba ze-SIGMA, nithi kunye ne-carbides, kukhokelela ekuchaseni nasekunciphiseni ukumelana nokunganyangeki. I-Dulex i-pie yentsimbi yentsimbi yintsimbi ye-ultra efanelekileyo ukuze isetyenziswe kwiimeko zoncedo kakhulu apho kufuneka khona amandla aphezulu oomatshini.
