1. Dab tsi yog cov ntawv thov tseem ceeb ntawm Incoloy 800 thiab Hastelloy C276 raj?
Teb:
Incoloy 800 raj yog dav siv nyob rau hauv siab - qhov kub thiab txias ib puag ncig, xws li tshav kub exchangers, lub cub tawg Cheebtsam, thiab cov khoom siv tshuaj, vim lawv zoo heev tiv thaiv oxidation thiab carburization.
Hastelloy C276 raj feem ntau yog siv nyob rau hauv cov tshuaj corrosive ib puag ncig, nrog rau cov tshuaj reactors, acid tuav, thiab cov cuab yeej tswj kev ua qias tuaj, ua tsaug rau lawv cov kev tiv thaiv zoo rau cov muaj zog oxidizers thiab txo cov neeg ua haujlwm.
2. Dab tsi yog qhov txawv ntawm ASTM B515 thiab lwm yam ASTM cov qauv rau nickel alloy raj?
Teb:
ASTM B515 tshwj xeeb npog cov welded thiab seamless npib tsib xee alloy raj rau siab - kub thiab siab - kev pabcuam siab. Nws txhais cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab cov kev xeem yuav tsum tau ua. Lwm cov qauv, xws li ASTM B829 lossis B837, tuaj yeem npog ntau hom nickel alloy tubing (piv txwv li, seamless nkaus xwb lossis tshwj xeeb corrosion- qib tiv taus).
3. Qhov ntsuas kub npaum li cas rau Incoloy 800 raj?
Teb:
Incoloy 800 raj tuaj yeem ua haujlwm tau zoo ntawm qhov kub ntawm -196℃mus rau ib ncig ntawm 760℃(txog -}321℃F txog 1400℃F). Lawv zoo heev kub-kub lub zog thiab oxidation kuj ua rau lawv zoo tagnrho rau kev pab mus sij hawm ntev nyob rau hauv lub cub tawg thiab kub exchanger daim ntaub ntawv.
4. Hastelloy C276 tiv thaiv corrosion li cas?
Teb:
Hastelloy C276 muaj molybdenum siab thiab chromium cov ntsiab lus, uas tsim ib tug ruaj khov passive oxide txheej ntawm qhov chaw. Cov txheej no tiv thaiv lub raj los ntawm cov tshuaj lom neeg, suav nrog sulfuric acid, hydrochloric acid, thiab chlorine- muaj ib puag ncig. Nws kuj tiv taus pitting, crevice corrosion, thiab kev nyuaj siab corrosion cracking.
5. Cov raj Incoloy 800 thiab Hastelloy C276 puas tuaj yeem welded thiab fabricated yooj yim?
Teb:
Yog lawm, ob qho tib si alloys tuaj yeem welded, tab sis cov txheej txheem tsim nyog yog tsim nyog:
Incoloy 800: Tau welded siv cov txheej txheem austenitic stainless hlau vuam txheej txheem, tab sis preheating feem ntau tsis tas yuav tsum tau. Tom qab-weld nyem nyem tuaj yeem txhim kho kev ua haujlwm hauv siab -kev siv kub.
Hastelloy C276: Yuav tsum tau ua tib zoo vuam nrog cov khoom siv sib xyaw ua ke (xws li C276 muab tub lim) kom tsis txhob muaj qhov tsis xws luag. Tom qab-vuam tu feem ntau pom zoo kom muaj kev tiv thaiv corrosion.
