Cov ntawv thov rau Incoloy 825
Incoloy 825 yog npib npib npib tsib xee-chromium alloy uas tau siv dav hauv cov roj thiab roj thiab cov txheej txheem siv tshuaj lom neeg. Nws muaj cov zoo corrosion tsis kam thiab muaj peev xwm ua haujlwm ntawm cov kev ua haujlwm siab dua li feem ntau steel hlau.
Dab tsi yog incoloy?
Incoloy yog cov cim lag luam ntawm cov neeg tshwj xeeb ntawm cov hlau sib txuas ua ke ntawm Nickel-hlau-chromium alloys. Cov kab npib Nickel yog qee zaum hu ua corrosion-resistant alloys (HPA) lossis txawm tias muaj kev sib tw ntawm Nickels, Cob kev ua haujlwm siab, cobalt lossis lwm yam me me.
Cov alloys tau nyob rau hauv kev txhim kho txij li xyoo 1990s thiab suav nrog Alloy 825 (Uncoloo alsoy tau tsim los muab cov khoom lag luam zoo dua. Qhov nqi them no tau ua tiav los ntawm kev txo tus (kim) cov ntsiab lus npib tsib xee.
Alloy 825 muaj cov ntsiab lus npib tsib xee ntawm ntau dua 40%, ua kom nws txoj kev tiv thaiv tsis txaus siab rau kev tawg. Kev sib ntxiv ntawm cov titanium inhibit intergranular corrosion uas yuav tshwm sim thaum muaj kub. Ntxiv ntawm Molybdenum thiab tooj pub rau nws tiv thaiv kom tsawg ib puag ncig xws li siv ntau yam ntawm kev thov Xaus ntawm cov txheej txheem tshuaj lom neeg.
Nrog zoo corrosion tsis kam thiab muaj kev ua haujlwm ntau ntau, incoloy 825 alloy tau siv dav hauv cov roj thiab roj av, risers, ntxawg. Langley alloys 'kev sib koom tes nrog cov khoom sib txuas txhais tau tias ntxiv rau cov khoom tawg, peb muaj peev xwm muab cov yeeb nkab, flanges thiab fittings. Cov Bar yog muaj los ntawm Tshuag hauv diameters xws li ntawm 3/4 nti mus rau 10 ntiv tes.
Dab tsi yog cov ntawv thov ntawm Incoloy 825 alloy?
Cov ntawv thov hauv cov txheej txheem tshuaj lom neeg suav nrog cov thermowells thiab sensors, hydrogen thiab ethylene rauv, thiab cov khoom siv rau cov nroj tsuag ammonia thiab ammonia. Cov Cheebtsam raug suav nrog cov hlab ntsha los tuav dej hiav txwv, amonium sulfate, pickling acid, sulfuric acid thiab phosphoric acid.
Alloy 825 tseem raug pom zoo rau siv nyob rau hauv siab cov nkoj ua haujlwm txog 525 Qib (ASMIE BOILER thiab Mev, IX, 1936 Nat}). Alloy 825 tuaj yeem tsim cov theem siab loj ntawm qhov kub ntawm 540 degree thiab tsis yog siv thaum muaj qhov kub thiab txias vim tias kev txiav txim siab yog kev txiav txim siab.
