Incoloy 800 Hyog npib tsib xee- hlau-chromium alloy optimized rau siab -kub cov qauv siv, muab superior creep thiab rupture zog siab tshaj 1100℃F (593℃).
Tsab ntawv xov xwm no qhia txog thawj hom Incoloy 800H flanges, qhia txog lawv cov qauv tsim, qhov zoo, thiab kev siv.
Weld caj dab Flanges
Weld caj dab flanges, tseem hu ua vuam caj dab flanges, feature ib tug ntev tapered hub uas hloov smoothly mus rau lub yeeb nkab phab ntsa, muab kev txhawb zog tiv thaiv kev kub ntxhov thiab kub hloov. Nyob rau hauv Incoloy 800H, cov flanges no yog forged los ntawm cov tuav los yog daim hlau ib ASTM B408 thiab B564, nrog lub hub welded ncaj qha mus rau cov yeeb nkab kawg siv cov tswv yim zoo li TIG los yog MIG.
Qhov kom zoo dua ntawm Incoloy 800H weld caj dab flanges nyob rau hauv lawv cov kev txhim kho creep kuj. Piv txwv li, nyob rau hauv ethylene cracking furnaces los yog hydrocarbon ua, cov flanges no tiv thaiv kom txhob xau thiab tswj system efficiency, txo tus nqi txij nkawm mus txog 30% piv rau cov qauv alloys.
Peb lub Hoobkas tsim cov vuam caj dab flanges hauv qhov ntau thiab tsawg ntawm 1/2 "mus rau 60" NPS, nrog kev ntsuas siab los ntawm Chav Kawm 150 txog 2500, ua raws li ASME B16.5 qhov ntev. Lub ntsej muag tsa (RF) lossis lub nplhaib- hom kev sib koom ua ke (RTJ) qhov chaw sib khi ua kom muaj roj- sib txuas nruj txawm tias muaj leej faj- muaj huab cua.
Txim-Ntawm Flanges
Slip- ntawm flanges swb hla cov yeeb nkab kawg thiab yog fillet-welded ob sab hauv thiab sab nraud kom ruaj ntseg txuas. Tsim los ntawm Incoloy 800H daim ntawv los yog phaj ntawm kev txiav thiab machining ib ASTM B409, cov flanges no muab tus nqi -txoj kev zoo rau vuam caj dab thaum tswj siab - qhov kub thiab txias.
Incoloy 800H txhim kho plam- ntawm flanges nrog kev ua haujlwm zoo rau oxidation thiab nitriding, ua rau lawv haum rau nruab nrab - cov tshuab siab txog li 1100℃F (593℃).
Lawv cov hub profile txo qis kev siv cov khoom siv, txo cov nqi yam tsis muaj kev cuam tshuam rau cov hlau tsis muaj zog corrosion nyob rau hauv ib puag ncig xws li flue gas desulfurization lossis tshuaj ua haujlwm. Qhov zoo muaj xws li kev sib dhos yooj yim thaum lub sijhawm teeb tsa thiab txo lub sijhawm vuam, uas txo qis kev cuam tshuam ntawm cov cua sov- cov ntawv thov rhiab heev.
Muaj nyob rau hauv peb cov kab los ntawm NPS 1/2 "rau 24", nrog lub ntsej muag tiaj tus (FF) lossis tsa lub ntsej muag xaiv, cov flanges no ua tau raws li DIN 17460 thiab EN 10095 tus qauv. Hauv lub tshuab hluav taws xob superheaters lossis cov chaw tsim khoom siv hluav taws xob, Incoloy 800H plam- ntawm flanges muab kev pabcuam txhim khu kev qha, txuas lub neej ntawm cov cuab yeej thiab ua kom muaj kev ua raws li cov cai nruj nruj.
Qhov (socket) Weld Flanges
Lub qhov (socket) weld flanges suav nrog lub qhov (socket) recessed qhov twg cov yeeb nkab kawg yog ntxig thiab fillet -welded los ntawm sab nraud, tsim kom muaj qhov sib npaug rau cov dej ntws. Forged los ntawm Incoloy 800H ib ASTM B564, cov flanges no zoo tagnrho rau me me -inch, siab - cov kab siab.
Cov alloy siab nickel (30-35%) thiab chromium (19-23%) cov ntsiab lus imparts zoo heev tiv thaiv kev ntxhov siab corrosion cracking, ib qho txiaj ntsig tseem ceeb hauv lub qhov (socket weld) tsim muaj kev co. Ntawm qhov kub siab, Incoloy 800H socket weld flanges nthuav tawm tsawg kawg nkaus, ua kom muaj kev ruaj ntseg hauv kev siv xws li cov tshuab hluav taws xob nuclear lossis acetic acid ntau lawm.
Peb cov khoom muaj xws li qhov ntau thiab tsawg mus txog NPS 3", nrog rau Chav Kawm 300 txog 1500 qhov kev ntsuam xyuas, muaj qhov tseeb qhov tob rau kev pom cov yeeb nkab ntxig.
Lawv cov qauv tsim thiab cov khoom siv vuam muaj zog ua rau Incoloy 800H qhov (socket) vuam flanges tseem ceeb rau qhov chaw - txwv tsis pub, siab - kev ntseeg tau.
Threaded Flanges
Threaded flanges ntsia hlau ncaj qha mus rau cov yeeb nkab xov, tshem tawm vuam rau kev sib dhos ceev hauv qis - cov tshuab siab. Machined los ntawm Incoloy 800H tuav hauv qab ASTM B408, lawv muaj NPT lossis BSP xov rau kev ruaj ntseg, xau{4}} cov ntaub ntawv sib txuas.
Incoloy 800H lub thermal stability tiv thaiv xov galling los yog ntes ntawm qhov kub txog li 1500℃F, muab qhov zoo dua carbon steels hauv cyclic cua sov ib puag ncig. Hom no ua tau zoo nyob rau hauv kev teeb tsa ib ntus lossis qhov chaw vuam tsis zoo, xws li hauv cov kab tshuaj lom neeg lossis cov cuab yeej siv.
Peb muab threaded flanges nyob rau hauv NPS 1/2 "mus rau 4", Chav Kawm 150 txog 900, nrog los tiv thaiv - corrosive coatings muaj. Hauv cov khoom siv hluav taws xob los yog diphenol ua, lawv muab kev saib xyuas yooj yim thiab kev tiv thaiv corrosion, txo qis sijhawm. Incoloy 800H threaded flanges kom ua tau zoo, weld-cov kev daws teeb meem dawb uas tswj kev ua haujlwm hauv kev tawm tsam hnyav.
Lap Joint Flanges
Lap sib koom ua ke flanges muaj qhov kawg ntawm qhov kawg thiab ib qho xoob nraub qaum flange, tso cai rau kev sib hloov rau bolt sib dhos. Lub nplhaib flange yog forged los ntawm Incoloy 800H ib ASME SB564, thaum lub qhov kawg ntawm cov khoom siv yeeb nkab.
Qhov kev tsim no leverages Incoloy 800H lub carburization tsis kam, zoo tagnrho rau cov tshuab uas yuav tsum tau nquag disassembly. Qhov zoo muaj xws li kev txuag nqi ntawm cov khoom sib txawv rau lub nplhaib nkaus xwb thiab txo kev ntxhov siab los ntawm misalignment. Hauv vinyl chloride cracking lossis furnace fixtures, lap joint flanges pab kev soj ntsuam yam tsis muaj kev cuam tshuam cov alloy siab siab -kub prowess.
Peb qhov ntau yam npog NPS 1/2 "mus rau 24", nrog RF lossis FF ntsej muag, ua raws li ISO 9723. Lawv qhov yooj thiab durability ua rau Incoloy 800H lap Joint flanges muaj peev xwm ntse rau cov kav dej hauv cov kav dej hauv corrosive, kub kub.
Qhov muag tsis pom Flanges
Qhov muag tsis pom flanges foob cov yeeb nkab kawg los yog lub nkoj qhib, muab cov khoom thaiv tsis muaj kev hla. Tuag-forged los yog machined los ntawm Incoloy 800H daim hlau ib ASTM B409, lawv tiv taus tag nrho lub zog siab.
Incoloy 800H qhov muag tsis pom flanges tiv thaiv sulfidation thiab intergranular corrosion, tseem ceeb heev rau blanking tawm kab hauv petrochemical nroj tsuag lossis kev sim siab. Lawv lub ntsej muag tiaj tus lossis tsa ntsej muag ua kom cov ntsaws ruaj ruaj nrog cov gaskets, tiv thaiv kom tsis txhob muaj qhov kub ntawm -cov xwm txheej kub.
Ua nyob rau hauv qhov ntau thiab tsawg NPS 1/2 "mus rau 60" thiab Chav Kawm 150 txog 2500, peb qhov muag tsis pom flanges tau raws li VdTÜV 412 tus qauv. Hauv daim ntawv thov nuclear lossis acidic, lawv muab kev nyab xeeb tsis sib haum xeeb thiab kev ua neej ntev, ua rau lawv tseem ceeb rau kev ua haujlwm cais.
Ntev Weld Neck Flanges
Ntev weld caj dab flanges txuas lub hub rau kev txuas ncaj qha ntawm lub nkoj, ua raws li ib qho nozzles. Machined los ntawm Incoloy 800H forgings ib ASTM B564, lawv tshem tawm cov welds ntxiv.
Incoloy 800H's oxidation kuj ntawm 1800℃F (982 degree) suits lawv rau siab -stress boiler Cheebtsam los yog reactors. Qhov zoo muaj xws li txo txoj kev xau thiab txhim kho lub neej qaug zog hauv kev pabcuam cyclic.
Peb cov khoom nthuav dav NPS 1/2 "rau 12" thiab kev cai ntev, ntsib ASME Tshooj VIII. Hauv kev ua haujlwm thermal lossis kev siv hluav taws xob, kev sib txuas ntev ntev -caj dab flanges xyuas kom muaj kev ncaj ncees, ua pov thawj lawv tsim nyog hauv cov txheej txheem tseem ceeb.
Xaus
Txawm hais tias hom flange tau xaiv-txawm nws yog qhov muaj zog Weld Neck rau koj qhov siab - cov kab hluav taws xob siab los yog kev lag luam Lap Joint rau koj qhov qis - siab vents- xyuas kom koj cov chaw tsim khoom muab daim ntawv pov thawj Mill Test (MTC) xyuas ob qho tib si chemistry thiab grain loj.
Ntawm JN, peb tsis yog muag flanges xwb; peb muag qhov kev lees paub tias koj qhov siab - qhov kub thiab txias yuav tuav nws txoj kev ncaj ncees thaum tshav kub kub.
