Lub tshav kub exchanger stainless hlau raj tau txais cov txheej txheem kev kho mob tshwj xeeb nrog rau siab -kub tshuaj annealing ua raws li kev ntxhov siab thib ob. Qhov no ua kom cov qauv zoo ib yam thiab ruaj khov metallographic muaj peev xwm tiv taus ntau txhiab lub voj voog thermal hloov pauv -xws li ntawm -20℃mus rau 650℃-tsis muaj qhov cuam tshuam thermal qaug zog, kev ua haujlwm tsis zoo, lossis kev ntxhov siab tawg.
Leveraging lub siab chromium-nickel alloy muaj pes tsawg leeg muaj nyob rau hauv stainless hlau, ib tug ntom, tiv thaiv oxide zaj duab xis rau ntawm lub raj nto. Nyob rau hauv kev ua haujlwm ntawm 600 degree, qhov siab -kub oxidation tseem tsawg dua lossis sib npaug li 0.02 g / (m²·h). Qhov no muaj txiaj ntsig zoo tiv thaiv oxidation uas tshwm sim los ntawm sulfur dioxide, nitrogen oxides, cov khoom me me, thiab cov kab mob ntawm cov tshuaj chlorine thiab sulfur- uas muaj cov xov xwm muaj nyob rau hauv cov hluav taws xob fais fab nroj tsuag flue gases, yog li tiv thaiv tube phab ntsa thinning thiab to thaum lub sijhawm ua haujlwm ntev.

Cov qhab nia xaiv tau
- Piv rau TP309H, TP310H, thiab TP347H, TP304H muaj cov nqi qis dua thaum pom cov oxidation zoo heev nyob rau hauv qhov kub thiab txias ntawm 550-650 degree.
- TP321H ua hauj lwm raws li ib tug siv tau lwm txoj rau TP347H; nws cov titanium stabilization muab kev tiv thaiv rau intergranular corrosion, ua rau nws haum rau siv nyob rau hauv superheater seem (tshwj xeeb yog nruab nrab-kub aav).
- Rau siab - qhov kub thiab txias ib puag ncig xws li 600℃txog 900℃, Incoloy 800H lossis 800HT tuaj yeem raug xaiv los ua lwm txoj hauv kev, muab qhov tshwj xeeb tiv thaiv rau thermal qaug zog thiab ua pov thawj zoo heev rau ultra-supercritical boilers.
thaj chaw thov
ASTM A213 stainless hlau raj yog dav siv nyob rau hauv boiler tshav kub hloov Cheebtsam uas yuav tsum tau tiv taus huab cua kub thiab siab tej yam kev mob, xws li superheater hlab thiab reheater hlab.

FAQ
Q: Yuav ua li cas xaiv tubing cov ntaub ntawv rau fais fab nroj tsuag tshav kub exchangers?
A: TP304H → Huv, tsis tshua muaj - kub flue gas & ruaj khov kev ua haujlwm
TP316H → Mildly corrosive flue gas & pov tseg tshav kub rov qab systems
TP321H → Nquag pib- nres & hnyav caij tsheb kauj vab
TP347H → High-kub, siab -siab & corrosive tseem ceeb seem (xws li, superheaters)
Q: Dab tsi yog qhov txawv ntawm H- qib stainless hlau tubing thiab tus qauv stainless hlau tubing?
A: H- qib stainless hlau (0.04–0.10% C) muaj cov pa roj carbon ntau dua, tsim cov carbides ruaj khov ntawm qhov kub thiab txias.
Qhov no ua rau muaj txiaj ntsig zoo rau kev nkag siab - tawg lub zog thiab ntev- lub sij hawm siab - qhov kub thiab txias, ua rau nws tsim nyog rau boiler kub seem xws li superheaters piv rau cov qauv qib.
Q: Dab tsi tsis yog -txoj kev kuaj kev puas tsuaj muaj feem xyuam rau ASTM A213 tubing?
A: Txhua qhov ntev ntawm A213 tubing yuav tsum tau kuaj xyuas hydrostatic los yog tsis yog -kev ntsuas hluav taws xob puas tsuaj. Tsis tas li ntawd, Eddy Current Testing (ET) thiab/lossis Ultrasonic Testing (UT) yuav ua tau raws li cov neeg siv khoom tshwj xeeb.
