Heat Exchangers yog dab tsi?
Thaum tshav kub kub exchangers yog ib qho tseem ceeb nyob rau hauv ntau yam kev lag luam, xws li petrochemical, tshuaj, thiab roj thiab roj. Lawv yog siv los hloov cov cua sov ntawm ob cov kua dej kom tswj tau qhov kub thiab txias rau cov txheej txheem. Thaum tshav kub kub exchanger raj muaj xws li cov raj ncaj thiab "U" zoo li lub raj. Ib qho tseem ceeb tshaj plaws ntawm cov khoom siv hluav taws xob yog cov khoom siv tubing, thiab ib qho ntawm cov khoom siv tubing nrov siv yogASTM A789 UNS S31803 Cov Lus Qhia Tshwj Xeeb
ASTM A789 Txuj
ASTM A789 yog tus qauv tshwj xeeb rau seamless thiab welded ferritic / austenitic stainless hlau tubing rau kev pabcuam dav dav. UNS S31803 yog ib qho duplex stainless hlau uas muab cov khoom zoo tshaj plaws ntawm ferritic thiab austenitic steels.ASTM A789 Duplex 2205 Tubemuaj lub zog zoo heev thiab kev tiv thaiv corrosion, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau cov cua kub exchanger raj.
ASTM A789 UNS S31803 Cov Khoom Siv Khoom
1. Duplex Stainless Steel Advantage:
ASTM A789 UNS S31803 Cov Lus Qhia Tshwj Xeebyog ib tug duplex stainless hlau, tus yam ntxwv los ntawm ib tug ob-theem microstructure uas muaj ob qho tib si austenitic thiab ferritic theem. Qhov no1.4462 cov khoomdual-theem qauv imparts superior corrosion kuj, ua rau nws tshwj xeeb tshaj yog haum rau daim ntaub ntawv nyob rau hauv nruj ib puag ncig ntsib nyob rau hauv lub tshav kub exchanger systems.
2. Corrosion Resistance:
Duplex stainless hlau, suav nrogUNS S31803, pom zoo tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj chloride. Cov cuab yeej no yog qhov tseem ceeb hauv kev siv cov khoom siv hluav taws xob uas muaj cov khoom corrosive ntau.
3. Lub zog muaj zog:
2205 duplex stainless hlau yeeb nkabmuab siab tensile thiab yield zog, pab rau tag nrho cov qauv kev ncaj ncees thiab durability ntawm tshav kub exchanger raj. Qhov no yog qhov tseem ceeb hauv kev siv qhov twg mechanical zog yog qhov tseem ceeb.
4. Zoo Weldability:
Lub duplex xwm ntawm UNS S31803 kuj pab txhawb rau nws zoo weldability, yooj yim rau fabrication thiab installation ntawm tshav kub exchanger hlab. Qhov no yog qhov tseem ceeb hauv kev tsim cov txheej txheem.
5. Temperature Resistance:
2205 duplex stainless hlau tubingpaub txog lawv qhov kev ua tau zoo ntawm qhov kub siab, ntxiv rau lawv qhov tsim nyog rau kev siv cov khoom siv hluav taws xob sib txawv uas muaj qhov sib txawv ntawm qhov kub thiab txias.
