ASTM A171 Txuj Kev Qhia Tshwj Xeeb rau Copper-Alloy Phaj thiab Ntawv rau Cov Nkoj Siab, Condensers, thiab Kub-Exchangers
Hauv cov khoom siv hluav taws xob, cov condensers, thiab lwm cov hlab ntsha siab, cov ntaub ntawv raj yog qhov tseem ceeb vim tias lawv ua qhov cuam tshuam ntawm cov kua dej ntawm ib sab thiab cov hlab rau lwm qhov. Txhawm rau tiv thaiv cov kev xav tau ntawm kev ua haujlwm uas lawv raug, cov khoom no yuav tsum muaj cov khoom siv zoo, kev tiv thaiv corrosion, thiab kav ntev. Ntxiv rau kev muab cov ntawv raj uas muaj cov khoom siv hlau sib txawv, TS muaj peev xwm muab ASTM A171 C46400 Naval Brass tube nplooj ntawv hauv ntau qhov ntev.

Cov tooj liab-nickel alloy hu ua ASTM A171 C46400 yog paub zoo tias muaj kev tiv thaiv corrosion zoo, tshwj xeeb tshaj yog nyob rau hauv hiav txwv tej yam kev mob. Copper (Cu) ua nyob ib ncig ntawm 59 feem pua ntawm nws cov muaj pes tsawg leeg, nrog me me ntawm hlau (Fe) thiab zinc (Zn). Qhov no alloy, tseem hu ua navy tooj dag, yog zoo meej rau daim ntawv thov tubesheet vim nws tshwj xeeb ua ke ntawm txhua yam muaj zog, ductility, thiab yaig kuj. Kev tiv thaiv corrosion zoo heev yog pom los ntawm ASTM B171 C46400, tshwj xeeb tshaj yog nyob rau hauv hiav txwv tej yam kev mob. Nws muaj qib siab ntawm kev tiv thaiv rau ob qho tib si hauv zos thiab tag nrho corrosion coj los ntawm cov dej ntsev, dej brackish, thiab cov khoom siv tshuaj. Vim yog cov khoom siv tooj liab thiab npib tsib xee alloy, uas tsim cov txheej txheem tiv thaiv oxide ntawm nws qhov chaw kom tsis txhob muaj kev xeb ntxiv thiab ua kom lub neej ntev, nws muaj kev tiv thaiv corrosion siab.

Siv cov txheej txheem fabrication, ASTM B171 C46400 yog ib qho yooj yim fabricatable thiab muaj peev xwm siv tau. Nws yog yooj yim molded, txiav, drilled, thiab machined kom los siav tej yam specifications. Lub alloy lub ductility enables ib tug xov tooj ntawm kev tsim, xws li kub thiab txias txoj kev, vuam, thiab brazing. Ntawm ASTM A171 C46400, kev ua haujlwm xws li drilling, tig, milling, thiab shaping tuaj yeem ua tau zoo. Hauv kev sib piv rau cov hlau zoo tib yam, nws cov ntsiab lus tooj liab siab tuaj yeem ua rau cov cuab yeej hnav tawm sai dua. Yog li ntawd, kev txhawb nqa kev tsim khoom thiab ua tiav qhov yuav tsum tau ua yog nyob ntawm kev xaiv cov cuab yeej txiav tsim nyog thiab kev ua haujlwm machining.
