UNS N08825cev iWerkstoff Nr. 2.4858cov yeeb nkab, cov npib tsib xee no -hlau-chromium masterstroke tau tsim tshwj xeeb los tswj cov oxidizing hnyav thiab txo qhov chaw. Kev ua tau zoo ntawm Incoloy 825 welded raj tso siab rau nws qhov tshwj xeeb sib npaug ntawm cov ntsiab lus alloying. Tsis zoo li cov txheej txheem nickel alloys uas tseem ceeb rau ib hom kev tiv thaiv dua lwm tus, Alloy 825 sib npaug nws cov muaj pes tsawg leeg los tiv thaiv ntau yam kev tawm tsam corrosive ib txhij.
HT PIPE yog ib tug thawj coj stockist thiab exporter thoob ntiaj teb nrog ntau tshaj 16 xyoo ntawm kev txawj ntse nyob rau hauv thoob ntiaj teb kev lag luam. Peb muab cov kav dej, daim hlau, cov kab tuav, thiab ntau yam ntawm cov yeeb nkab fittings, flanges, thiab li qub.Tiv tauj pebtam sim no rau cov quotes dawb thiab cov ntaub ntawv khoom ntiag tug.

Manufacturing Standards thiab Formats
Txhawm rau kom muaj kev nyab xeeb thiab ua haujlwm tau zoo hauv cov ntawv thov tseem ceeb, Incoloy 825 yuav tsum ua raws li cov qauv thoob ntiaj teb nruj.
Core Manufacturing Specifications:
ASTM B163 / ASME SB 163 Cov Lus Qhia:Npog seamless npib tsib xee thiab npib tsib xee alloy condenser thiab kub exchanger raj.
ASTM B423 / ASME SB 423 Cov ntsiab lus:Standard specification rau seamless yeeb nkab thiab raj npaj rau kev siv corrosive.
ASTM B704 / ASME SB 704 Cov Lus Qhia:Regulates welded alloy raj tsim rau kev xav tau kev lag luam tshuab.
Xaiv txoj cai Form Factor
Seamless Tubing:Extruded thiab txias - kos los ntawm cov pob zeb. Vim tias nws tsis muaj vuam seam, nws muaj kev ntseeg siab rau siab - cov tshuab siab thiab cov ntawv thov ua rau thaj tsam galvanic corrosion.
Welded thiab Redrawn Tubing:Tsim los ntawm strips thiab plasma welded. Tom qab ntawd nws yog txias-rov qab thiab ci ntsa iab kom phim cov qauv kev sib xws ntawm cov kev xaiv seamless, ua rau nws tus nqi - kev xaiv zoo rau kev ua haujlwm ntev lossis kev zoo nkauj.
Coiled Tubing:Muab nyob rau hauv tas mus li ntev mus txog phav phav taw, txo qhov yuav tsum tau rau mechanical fittings los yog orbital vuam nyob rau hauv ntev hydraulic los yog tshuaj txhaj kab.
Kev ua haujlwm, vuam, thiab kev tu
Tsis zoo li ntau nkig superalloys, Incoloy 825 muaj cov qauv zoo. Nws tuaj yeem ua tau txias- ua haujlwm tau yooj yim thiab khoov kom nruj radii yam tsis tas yuav muaj kev ntxhov siab tam sim ntawd- nyem annealing, yog tias qhov deformation tseem nyob hauv cov txheej txheem engineering txwv.
Thaum nws los txog rau kev tsim, vuam yuav tsum tau ua tib zoo saib xyuas cov kev coj ua huv. Cov hlau tuaj yeem koom nrog siv Gas Tungsten Arc Vuam (GTAW / TIG) lossis Gas Hlau Arc Vuam (GMAW / MIG). Txhawm rau kom ntseeg tau tias cov hlau vuam sib tw rau kev tiv thaiv corrosion ntawm lub hauv paus raj, engineers feem ntau siv siab -kev ua tau zoo ntawm cov khoom siv xws liFiller Hlau 625los yogVuam Electrode 112. Kev tiv thaiv roj kom zoo nrog cov ntshiab argon yog qhov tseem ceeb los tiv thaiv oxidation raws cov hauv paus hniav.
Cov Txheej Txheem Txhim Kho Kev Ua Haujlwm
Txhawm rau ua kom lub neej ua haujlwm siab tshaj plaws ntawm Incoloy 825 tubing tes hauj lwm, cov kws ua haujlwm hauv teb yuav tsum ua raws li cov txheej txheem tuav thiab tsim khoom tshwj xeeb:
Zam Kev Tiv Thaiv Kab Mob
Thaum lub sij hawm khaws cia thiab kev teeb tsa, Incoloy 825 yuav tsum raug cais tawm ntawm cov cuab yeej carbon steel, scaffolding, thiab cia racks. Cov hlau tsis pub dawb tuaj yeem hloov mus rau saum npoo ntawm cov hlau, cuam tshuam nws cov chromium tiv thaiv- oxide passivation txheej thiab ua rau thaj chaw galvanic pitting. Siv cov hlau tsis muaj steel lossis roj hmab - cov khoom siv tuav.
Khoov thiab Springback
Alloy 825 ua hauj lwm- hardens sai dua li cov qauv me me. Thaum ua haujlwm txias khoov rau cov kab ntsuas:
- Siv hnyav-lub luag haujlwm, tshuab lossis hydraulic dabtsi yog khoov mandrels.
- Cia siab tias yuav muaj qib siab duacaij nplooj ntoos hlav(qhov nyiam ntawm cov hlau ib nrab rov qab los rau nws cov qauv qub). Khoov cov ces kaum yuav tsum me ntsis dhau - tig kom ua tiav qhov xav tau qhov kawg geometry.
Ncej -Wel Cleaning
Txawm hais tias titanium stabilization nyob rau hauv Alloy 825 tiv thaiv chromium carbide nag lossis daus thaum vuam, post-weld pickling lossis passivation raug pom zoo rau cov ntawv thov tseem ceeb. Tshem tawm cov xim tsis sib xws (tshav kub tint) ua kom ntseeg tau tias cov ntsiab lus chromium hauv qab no muaj tag nrho los hloov kho ib qho zoo, tiv thaiv oxide.
Tej kev siv
Tshuaj thiab Petrochemical:Cov nroj tsuag acetic, sulfuric, thiab phosphoric acid, tawg roj quenching systems nyob rau hauv ethylene nroj tsuag thiab organic synthesis txheej txheem uas muaj chlorides.
Marine Engineering thiab Seawater Desalination:Seawater cooling piping systems, preheaters, twj, thiab kav dej hauv seawater desalination nroj tsuag; thiab siab -siab seawater systems ntawm nkoj.
Flue Gas Desulfurization (FGD) Systems:Cov chaw ntub dej feem ntau raug cuam tshuam rau corrosion, xws li cov txheej absorber sprayer, demister, thiab qhov hluav taws xob flue.
Kev lag luam ntawv:Cov cuab yeej siv thiab cov kav dej hauv cov txheej txheem tshuaj dawb huv (ClO₂ ib puag ncig).
Pharmaceutical thiab Food Industries:Kev thov cov txheej txheem yuav tsum muaj kev huv huv thiab kev tiv thaiv corrosion.
Kev tiv thaiv ib puag ncig:Kev kho dej khib nyiab, tshwj xeeb tshaj yog rau cov dej khib nyiab uas muaj cov tshuaj chlorides, sulfides, lossis acidic Cheebtsam.
