U Tube Thaum tshav kub kub Exchanger yog tsim rau cov ntawv thov uas muaj qhov sib txawv ntawm qhov kub thiab txias, raws li lawv cov qauv tsim tso cai rau cov raj kom nthuav dav thiab cog lus ywj pheej, yog li ua kom haum rau qhov kub thiab txias. Tsis tas li ntawd, lawv muaj peev xwm ua hauj lwm nyob rau hauv siab - kub thiab siab - siab tej yam kev mob - feem ntau ntawm kub ntawm 450℃los yog qis dua thiab siab ntawm 6.4 MPa los yog qis dua.
Cov khoom siv raj tau txais kev daws teeb meem, cov txheej txheem uas ua kom tiav cov theem precipitated -xws li carbides thiab sigma theem - mus rau hauv austenitic matrix, uas ua rau ib qho zoo ib yam, ib zaug -theem microstructure thaum tshem tawm tag nrho cov kev ntxhov siab nyob hauv.
TP316 stainless hlau muaj 2-3% molybdenum, endowing nws muaj zog corrosion kuj. Raws li cov kev ua haujlwm raug cai-tshwj xeeb yog thaum cov tshuaj chloride ion (Cl⁻) concentration tsis tshaj 400 mg / L thiab qhov kub thiab txias tseem qis dua 130℃-TP316 stainless hlau ua haujlwm raws li cov khoom siv tsim nyog.
Customized Services
- TORICH muaj cov kev pabcuam sizing, ua kom cov khoom customization raws li cov duab kos los ntawm cov neeg siv khoom. Muaj qhov ntev los ntawm ib txoj kab uas hla ntawm 12.7 hli mus rau 50.8 hli thiab phab ntsa thickness ntawm 0.7 hli mus rau 5.0 hli, nrog ntev mus txog 25 meters (ua ntej khoov); kev cai qhov ntev kuj muaj raws li qhov kev thov.
- Rau cov ntawv siv hluav taws xob sib pauv uas xav tau kev huv huv siab, peb muab cov kev kho tshwj xeeb, suav nrog kev ci ntsa iab thiab sab hauv thiab sab nrauv polishing.
- TORICH tseem muaj ntau yam kev pabcuam, suav nrog kev txiav txiav rau qhov ntev, beveling, thiab tshwj xeeb dabtsi yog khoov rau cov duab tshwj xeeb.

Cov qhab nia xaiv tau
- 254SMO yog ib qho ultra- cov pa roj carbon tshwj xeeb stainless hlau uas muaj qhov ua tau zoo heev rau cov tshuaj chloride pitting thiab crevice corrosion. Nws yog ib qho kev xaiv tsim nyog rau ib puag ncig uas cov tshuaj chloride ion concentration ntau tshaj 1800 mg / L tab sis tseem qis dua 5000 mg / L, thiab qhov kub thiab txias yog nyob rau hauv 130 degree.
- 904L super-austenitic stainless hlau muaj cov haujlwm zoo heev -passive kev hloov pauv muaj peev xwm thiab tshwj xeeb corrosion kuj. Nws yog tsim rau ib puag ncig uas cov chloride ion concentration nyob rau hauv nruab nrab siab tshaj 400 mg / L tab sis tseem nyob rau hauv 1000 mg / L, thiab qhov kub thiab txias yog nyob rau hauv 130 degree.
- Rau ib puag ncig uas cov tshuaj chloride ion concentration tsis tshaj 100 mg / L thiab qhov kub ntawm 120 degree, 304 stainless hlau tuaj yeem xaiv; Tsis tas li ntawd, nws muaj tus nqi ntau dua - kev daws teeb meem zoo.
thaj chaw thov

FAQ
Q: Dab tsi yog qhov txawv ntawm TP316 thiab TP316L U- raj?
A: Qhov sib txawv ntawm TP316 thiab TP316L yog nyob rau hauv lawv cov ntsiab lus carbon; TP316L muaj cov ntsiab lus qis dua, uas txo qhov kev pheej hmoo ntawm intergranular corrosion tom qab vuam, ua rau nws tsim nyog siv rau hauv welded heat exchanger systems.
Q: Cov khoom ntim li cas?
A: Txhua lub raj muaj kev tiv thaiv los ntawm lub tes tsho yas thiab ntim rau hauv cov thawv ntoo kom tiv thaiv kev puas tsuaj los yog kis kab mob thaum caij tsheb npav.
Q: Dab tsi yog qhov siab tshaj plaws kev khiav hauj lwm kub rau ASTM A213 TP316 tshav kub exchanger raj?
A: Qhov ntsuas kub tsis tu ncua rau cov raj no yog kwv yees li 800 degree, thiab nyob rau hauv kev ua haujlwm tsis sib xws, lawv tuaj yeem tiv taus qhov kub txog li 870 degree.
