Ukufakwa kwamapayipi wensimbi

Okwe-Duplex Steel Flanses, isixazululo sokuhlehlisa endaweni yokushisa efanelekile elandelwa ukujula kwamanzi ngokushesha kungafinyelela ibhalansi yesigaba se-metallurgical aupurgical aupurtical aupunnical auustol-ferrite. Kubalulekile ukugcina isikhathi phakathi kokushiya isithando somlilo namanzi aqala ukucima amafushane ngangokunokwenzeka. Lokhu ukunciphisa ukulahleka kokushisa kusuka ku-flange, okungaholela ekutheni imvuthulo yezikhathi ezilimazayo ngaphambi kokucima amanzi okushisa kwegumbi.

I-Duplex Steel yangeniswa emakethe njengendlela yokubhekana nezinkinga ezihambisana nokuqhekeka okuhlobene nokugqwala okubangelwa izixazululo ze-chlorine. Ukwakheka kwamakhemikhali kwezinto ze-dulex Flange nazo zenza ama-flanges athambekele ekunciphiseni kwe-chlorine-angethe Lezi ze-alloys azibizi kakhulu kunezinsimbi ezisuselwa ku-nickel.

I-Chromium, i-molybdenum, i-nitrogen kanye ne-nickel yizinto ezibaluleke kakhulu zokuhlanganisa, ezinomphumela obalulekile kwimishini yezomshini, eyomzimba neyokugqwala yama-tungex ama-starless steres. I-Chromium iyadingeka ukwakha ifilimu yokuhamba ye-chromium ezinzile eyanele ukuvikela insimbi ekugcekeni komkhathi emkhathini. Okuphakeme okuqukethwe kwe-chromium, okungcono ukumelana nokugqwala.

Singomunye wabakhiqizi abakhulu kakhulu be-Dumplex Sliding Flanges enamandla amahle okukhathala kanye nokuphikiswa okuphezulu kokugqwala. I-2205 Duplex Steel Flielight Flange yaziwa nangezindawo zayo ezehlukene zemishini, njengokumelana kahle nokuqhekeka, ukupela, nokugqwala ezindaweni ezinokhahlo.

I-Duplex Sliding Sliding Ubuso Buso Flanges banokuphikiswa okuphezulu kokugqwala ku-Chloride-equkethe imithombo yezindaba, kufaka phakathi amanzi olwandle, okwenza leli banga lihle nge-Deepwater Impilicals kanye nohlu lwamanye ama-oyili kanye negesi.

Njengensimbi ye-alloy ephakathi nendawo, ama-dueplex blind aphakanyiselwe ubuso be-flanges anikela ngokumelana kahle nokugqwayiza kanye namandla emishini kwabezindaba abaningi uma kuqhathaniswa ne-astm evamile ye-astm 316l.

Ama-FLWISE APT-SPEL BET-WELD APT-Welded aphakamise i-FLLESE APPEL ahlinzeka ngemishini emihle kakhulu futhi engaguquki yesivinini esikhulayo sokusika, ukugqokwa kwethuluzi lokunciphisa kanye nesikhathi sokusetha.

I-2205 I-Dumplex Steel iqukethe isizinda sesigaba sesibili se-Ferrite ne-Ausun. Uma kukhulunywa ngokuqanjwa kwamakhemikhali kwama-flanges ensimbi angama-2205, ikakhulukazi aqukethe ama-chromium angama-22%, ama-3% molybdenum kanye no-5-6% nickel ngesimo sensimbi engenacala.

Abahlinzeki bensimbi engagqwali i-flain flainle ancoma leli banga elingenamicikilishelwa imisebenzi ngoba uhla lwamabanga angenasici lufana nohlu lokumelana olungenasici lufana nohlu lokuphikiswa lwensimbi olungenacala, isb.

Njengawo wonke amabanga angenasici angenasici, ukumelana nokugqwala kwensimbi noma i-alloy kuncike ngokuyinhloko ekwakhiweni kwensimbi, kuleli nsimbi engenacala. Ukumelana nokugqwala kwe-chloride nokugqwala kwe-chlorice, okuqukethwe yizinto ezifana ne-chromium, i-molybdenum ne-nitrogen kubhekwa njengokubaluleke kakhulu.

Okuqukethwe kwe-chromium kuphakathi kuka-20-28%, yingakho u-Ex S3180003 \ S32205 uFlonges oyimpumputhe uhlangabezana nento ebizwa ngokuthi yiPhathamezwe. Kulesi phenomenon, isendlalelo sokuzivikela esiphilisayo soxide esizungeza i-flange senze ukuthi imelane ne-oxidation.

Usayizi uhla luvela? " kuya ku-48 "

I-Chromium ingumbulisi wangaphambili, okusho ukuthi kukhuthaza ukwakheka kwe-BCC yensimbi. Kuphinde kwandise ukumelana ne-oxidation emazingeni okushisa aphezulu. I-Chromium ephakeme ibuye ikhuthaze ukwakheka kwezigaba zokuxhumana, ezilimaze kakhulu ama-Druplex Steel futhi kufanele kubhekwane nakho.

Ama-Flanges abuye abe nobuso obuhlukile obunjengobuso obuphakanyisiwe, ubuso obucwebezelayo kanye nokuhlangana kwendandatho. Izicelo ze-Flange zitholakala e-aerospace, izicelo zobunjiniyela zenhlosi yenuzi kanye namakhemikhali. Ama-Flanges e-duplex stainless butt anentamo ye-weld ukuthola imali eyengeziwe ngaphambi nangemva kokufudumala.

Ukwakheka kwamakhemikhali kweDuplex F51 Flanges kuqukethe ikhabhoni, i-chromium, i-manganese, molybdenum, nitrogen, nickel ne-phosphorus. Ama-Flanges asetshenziswa ezinhlelweni zokucindezela kanye nama-valve fittings.

Amabanga angenacala angenacala abizwa ngokuthi duplex ngoba la mabanga acishe abe ama-flange ane-flange Lesi sigaba sesigaba ezimbili i-missructure siqukethe okusanhlamvu okufana ne-auntenitic. Njengoba igama libonisa, ukwakhiwa kwe-duplex kunikeza le nto duplex yensimbi ye-socker ye-socker weld i-flange impahla ehlukahlukene yezakhiwo ezithandekayo.

Uma kuqhathaniswa nensimbi ehambisanayo ye-auntenitic, kuthambekele kakhulu ekumeni kwezulu kwezigaba ze-sigma, ama-nitrides kanye nama-carbides, okuholela ekulweni nokuphikiswa kokugqwala okuncishisiwe. Ama-Flanges e-Duplex Steel yi-Ultra-Steel efanele ukusetshenziswa kwezimo ezilimazayo lapho kudingeka khona amandla aphezulu emishini.

Inhlanganisela ye-chromium, i-molybdenum ne-nitrogen kunikeza ukumelana okuhle kwe-chloride nokugqwala kwe-crevice. Lokhu kumelana kubaluleke kakhulu kwizinsizakalo ezinjengezindawo zasolwandle, amanzi aqhekekile, imisebenzi yokubhula, izinhlelo ezivaliwe zamanzi e-loop kanye nezinye izinhlelo zokusebenza zokudla.

Ukwakheka kwezigaba zokuxhumana ezifana nesigaba se-SIGMA kuma-flange flange flange kwenzeka ezinhlwini zokushisa ze-600¡Ãc - 100¡Ãc, futhi ukubola kweFerrite kwenzeka kuhla lokushisa lwe-350¡Ãc - 5005¡Ãc (500) (4005¡Ãcc (4005¡Ãcc (4005¡Ãcc (4005¡Ãc (575¡Ãcc (4005¡Ãcc (4005¡Ãcc (4005¡Ãcc (4005¡Ãcc (4005¡Ãcc (4005¡ã

Ama-Flanses ensimbi engagqwali asetshenziswa kabanzi embonini kawoyela osogwini lolwandle kanye negesi lapho adalulwa khona kwimithombo yezindaba eqinile. Embonini kawoyela negesi, lapho imidiya ithuthwa ngokushesha eziteshini, izakhi ezisetshenziswe lapha zingaguga.

I-S32205 Duplex Steel Asme SA182 Butt Weld Flanges ilungele amanzi olwandle nemishini yokukhiqiza amandla ngoba izindawo zabo ezibushelelezi zingamelana namazinga okushisa aze afike ku-600¡ãf, ngenkathi enezimpawu ezinhle kakhulu zokugeleza.

Basiza ukuguqula futhi bahlanze ngisho nalezi zinhlelo zenqubo. Ukumelana nokugqwala kanye nezindawo ezishukumisayo zama-duplex sliding flanges anyusiwe kuqhathaniswa nama-flanges ensimbi engagqwali.

I-Molybdenum ikhulisa ukumelana nokugqwala okukhonkotha kanye ne-crevice. Kodwa-ke, okuqukethwe kwalo ku-Duplex Steel engenacala ngokuvamile kukhawulelwe ngaphansi kwama-4% ngoba uMo futhi u-Ferrite wangaphambili futhi angaholela ezigabeni ezingafuneki zokuhlasela. I-nitrogen ithuthukisa ukumelana nokugqwala okukhonkotha kanye ne-crevice.

I-ANSI B16.5 Dumplex kanye Super Dumplex Flinges Acters, ASTM A182 F44, F45, F51 FLANEL, FLANEL, FFULES, RTJ, TF ubuso ^ - I-Zhengzhou Huitong Pipeline Equipment Co, Ltd.

Imishini eminingi yokucubungula isebenzisa i-Duplex 2205. Iphinde isetshenziswe yi-Industrial Storage kanye namayunithi okuhamba. Ama-pulp kanye namaphepha okugaya, amathangi awuketshezi nemishini yamaphepha nawo asebenzisa i-duplex 2205. Ilungele ukusetshenziswa ezindaweni zasolwandle.

Kukhulisa futhi amandla njengento eqinile eqinile yokuqinisa into eqinile. I-nitrogen ingumuntu onamandla we-Auucen yangaphambili, futhi ukungezwa kwe-nitrogen kuthuthukisa kakhulu ubunzima bensimbi ebili-2. Ibuye ibe yihlele nokwakhiwa kwamakhompiyutha aphakathi nendawo anele okuvumela ukucubungula kanye nokuklanywa kwama-steel-phasigal steel. I-nickel yi-auntenituct stabilizer ekhuthaza ukwakheka kwesakhiwo se-FCC se-auntenitic FCC, esinomthelela ekubumbeni kwama-steel-phasigal steel.

Ama-Flanses ensimbi engagqwali asetshenziswa kabanzi ezinhlelweni zamapayipi, ama-Risers, ama-manholds, njll. Embonini kagesi aphesheya kwezimboni kanye nemboni yamafutha, futhi nasembonini ye-petrochemical ngendlela yemikhumbi yengcindezi namapayipi. I-Duplex 2205 Izinto ze-Flange zinamandla amahle kanye nokumelana okuphezulu ekugqwaneni, okukhonkotha kanye nokugqwala kwe-crevice. Ukwakheka kwamakhemikhali okuhlangene kwe-Duplex 2205 kungama-22% Chromium, 3.2% molybdenum, ama-5% ama-nickel nezinye izinto ezengeziwe ezinjenge-manganese ne-nitrogen.

Kwamabanga ajwayelekile ase-Aututenituc angenasici (njenge-304 no-316), i-SCC ingaba yinkinga ezindaweni zomswakama kanye namazinga okushisa aphezulu noma ngamakhemikhali athile afana nama-chlorides. Ngakho-ke, abahlinzeki be-Duplex Blind Flange bavame ukubanikeza ezimbonini ezinjengezimbotshana zamafutha nezimboni, igesi, izimboni ze-petrochemical nezasolwandle.

Njengoba i-nickel iyisitatimende sezimpahla, izindleko zokusebenzisa ama-alloys ahlelwe kakhulu kusetshenziswa ama-alloys athambekele ekubizeni kakhulu. Ngaphandle kokuqukethwe okuphansi kwe-nickel, ama-flangel angama-2205 ama-flangetes akwazi ukukhombisa izakhiwo ezimbalwa ezibalulekile ngenxa yokuqukethwe okuphezulu kwe-molybdenum ne-chromium.

Umqondo oyisisekelo we-bual-ganare butt ye-butt weld amaflethi ukukhiqiza ukwakheka kwamakhemikhali okwenze ingxube ecishe ilingane neFerrite ne-Ausunite. Ukwakheka kwamakhemikhali kwama-flanges e-duplex lensimbi kulinganiselwe ukukhiqiza cishe amanani alinganayo we-Ferrite ne-austonite ngaphansi kwezimo eziveziwe.
