Nyob rau hauv ib puag ncig dej hiav txwv, 70 30 tooj liab nickel raj tsim ib qhov ntom ntom, nws tus kheej- kho cov oxide zaj duab xis uas zoo tiv thaiv corrosion, pitting, thiab crevice corrosion. Nws cov kev tiv thaiv corrosion yog qhov zoo tshaj rau cov txhuas tooj dag thiab 316L stainless hlau, tshwj xeeb tshaj yog nyob rau hauv cov pa phem los yog sulfide- muaj dej hiav txwv. Tsis tas li ntawd, tooj liab ions nyob rau hauv 70/30 tooj liab-nickel alloy inhibit marine organism txuas, yog li txo qhov kev pheej hmoo ntawm microbiologically cuam tshuam corrosion.
Lub thermal conductivity ntawm C71500 tooj liab-nickel tubing ntawm 20℃yog kwv yees li 29 W/m·K- siab dua li ntawm 316L stainless hlau (kwv yees li 16 W/m·K) thiab titanium (kwv yees li 16–22 W/m·K} ntxiv rau){9} ntxiv rau Thaum tshav kub kub{10}} pauv kev ua tau zoo rau marine condensers thiab heat exchangers.

Cov qhab nia xaiv tau
- 90/10 Cu-Ni tubing (UNS C70600) muab cov nqi qis dua cov khoom siv thiab cov thermal conductivity me ntsis, ua rau nws tsim nyog rau cov dej hiav txwv huv huv uas muaj cov dej ntws qis dua thiab cov dej kub.
- Rau cov kav dej pab cuam qhov twg cov kev xav tau ntawm cov hluav taws xob hloov hluav taws xob yog qhov me me tab sis cov qauv kev xav tau siab, 316L lossis 2205 stainless hlau yog qhov kev xaiv tsim nyog vim nws lub zog txhua yam thiab tus nqi qis.
- Yog hais tias kev khiav hauj lwm tej yam kev mob xav tau tshwj xeeb seawater corrosion kuj thiab cov peev nyiaj tso cai, Qib 2 titanium tej zaum yuav raug xaiv rau daim ntaub ntawv uas yuav tsum tau ultra- muaj kev ntseeg siab, xws li lub ntsiab condensers los yog tshwj xeeb desalination units.
thaj chaw thov
Ua tsaug rau lawv cov kev tiv thaiv zoo heev rau cov dej hiav txwv corrosion thiab kev kub siab hloov pauv tau zoo, ASTM B111 70 30 tooj liab nickel raj yog dav siv nyob rau hauv ntau yam siab -kawg marine thermal zog hloov dua siab tshiab thiab txias tshuab, nrog rau cov hauv qab no:

FAQ
Q: Dab tsi yog qhov kub thiab txias ua haujlwm rau ASTM B111 70/30 tooj liab-nickel tubing?
A: Kev khiav hauj lwm kub yog -20℃mus rau 120 degree, npog feem ntau ntawm marine seawater tshav kub pauv thiab condensation daim ntaub ntawv. Cov ntaub ntawv pov thawj tsis muaj kev ua haujlwm degradation lossis cov qauv deformation thoob plaws tag nrho cov kab no, ua rau nws tsim nyog rau cov cheeb tsam hauv hiav txwv raws caij nyoog hloov pauv.
Q: Lub raj puas tuaj yeem welded?
A: Yog. 70/30 tooj liab-nickel alloy muaj qhov zoo tshaj plaws weldability; Cov txheej txheem vuam feem ntau suav nrog TIG, MIG, thiab phau ntawv arc vuam. Thaum lub sij hawm welding, kev sib kis ntawm cov hlau los yog carbon hlau yuav tsum raug zam, thiab cov tooj liab sib xws -nickel vuam consumables yuav tsum tau siv.
Q: Vim li cas 70/30 tooj liab -nickel tubing pom zoo rau seawater heat exchange applications piv rau stainless hlau tubing?
A: Stainless hlau xws li 316L yog qhov yooj yim rau pitting thiab crevice corrosion nyob rau hauv seawater ib puag ncig. Hauv qhov sib piv, 70/30 tooj liab-nickel tubing haum rau ntau yam ntawm cov dej hiav txwv ntws nrawm, muaj kev tiv thaiv zoo tshaj plaws thiab biofouling, thiab ua kom muaj kev ntseeg tau ntev dua -.
