Cov qhab nia xaiv tau
- Rau cov roj crude preheaters-feem ntau yog cov kev khiav hauj lwm yam tsis muaj acidic media thiab nrog ib tug tsim kub hauv qab 350℃- xaiv 1.4307 (304L) raws li ib tug hloov rau 1.4404 (316L) muab cov nqi zoo heev -effectiveness.
- Rau cov ntawv thov uas muaj qhov ntev -lub sij hawm sib pauv cua sov ntawm qhov kub siab tshaj 400 degree, kev siv 1.4541 (321)-titanium-stabilized stainless hlau- raug pom zoo los ua lwm txoj hauv kev rau 316L, raws li nws zoo txo qhov kev pheej hmoo ntawm high{8} corrosion.
- Rau ib puag ncig uas muaj cov tshuaj chloride siab, acidic roj thiab roj, lossis dej hiav txwv txias, 1.4462 (2205) yog qhov kev xaiv tsim nyog; Txawm hais tias nws cov nqi pib siab dua li ntawm 316L, nws muaj lub neej ua haujlwm ntev dua.
thaj chaw thov
Peb EN 10217-7 stainless hlau U-bent welded tshav kub exchanger raj yog tsim tshwj xeeb rau siv nyob rau hauv refinery tshav kub exchangers. Cov ntawv thov no suav nrog, tab sis tsis txwv rau, cov roj crude preheaters, atmospheric thiab nqus distillation heat exchangers, catalytic cracking slurry heat exchangers, heat exchangers for hydrocracking and hydrotreating reactor effluents, coking fractionation tower heat exchangers, and heat exchangers for desalting and dehydration systems, thiab lwm yam refinery units.

FAQ
Q: Dab tsi yog qhov tsawg kawg nkaus dabtsi yog khoov vojvoog rau U- raj?
A: Raws li EN 10217-7 thiab TEMA cov qauv, tus qauv yam tsawg kawg nkaus dabtsi yog khoov vojvoog (R) yog 1.5 npaug ntawm txoj kab uas hla (R=1.5D); Txawm li cas los xij, qhov no tuaj yeem hloov kho kom tau raws li cov neeg siv khoom tshwj xeeb.
Q: Dab tsi ntawm phab ntsa thickness txo ntawm qhov khoov? Qhov no puas tuaj yeem them nyiaj rau?
A: Cov phab ntsa thinning tus nqi ntawm lub thinnest point ntawm lub sab nrauv ntawm lub khoov yog tswj kom nyob twj ywm nyob rau hauv 12% ntawm thawj phab ntsa thickness. Raws li tus neeg thov kev thov, peb tuaj yeem them nyiaj rau qhov thinning no los ntawm kev xaiv cov hlab nrog cov phab ntsa tuab me ntsis ua ntej khoov, yog li xyuas kom meej tias qhov tsawg kawg nkaus phab ntsa thickness ntawm qhov khoov tau raws li txhua qhov kev tsim tshwj xeeb.
Q: Muab piv rau cov raj seamless, cov welded steel raj puas yooj yim dua rau kev tawg nyob rau hauv qhov siab - kev khiav hauj lwm siab ntawm cov refinery tshav kub exchangers?
A: Tsis yog, lawv tsis yog. Peb cov raj tau dhau los ua cov txheej txheem tshuaj xyuas ob zaug nruj heev- suav nrog 100% eddy tam sim no kuaj thiab kuaj hydrostatic- kom ntseeg tau tias lub zog ntawm cov vuam seam yog tag nrho sib npaug ntawm cov khoom siv hauv paus.
