Yog tias koj tau nce mus rau hauv cov nroj tsuag tshuaj, koj yuav pom ib yam dab tsi striking - ntau ntawm cov twj thiab cov tso tsheb hlau luam rau cov hlau uas stainless hlau. Thiab ntau zaus tshaj li tsis, cov khoom ntawd yog 316L.
Nws yooj yim rau xav tias nws tsuas yog "corrosion - tsis kam," tab sis cov laj thawj tiag tom qab nws siv ntau dua mus tob. Ntawm no yog ib qho ze saib ntawm dab tsi ua rau 316L txoj kev xaiv tau ntseeg hauv qee qhov kev lag luam muaj kev lag luam feem ntau.
1. Cov ntsiab lus tseem ceeb: Kev tawm tsam chloride nres
Hauv kev ua yeeb yam, ib qho kev hem thawj loj tshaj plaws rau cov khoom sib xyaw hlau yog chloride -}} Cov dej txias, lossis cov txheej txheem ntws. Txheem stainless hlau zoo li 304 cia li 304 vam khom rau cov txheej txheem khib nyiab
Qhov ntawd yog qhov chaw 316L sawv sib nrug. Nws muaj pes tsawg leeg suav nrog 2-3% molybdenum.
Molybdenum hloov zog ntxiv dag zog rau txheej passive, tshwj xeeb tshaj tawm tsam chlorides thiab lwm yam nres. Nws pab tiv thaiv ob qho pitting thiab crevice corrosion - cov hom hlau puas tuaj yeem tiv taus ntev ntev. Tsuas yog muab tso, molybdenum yog dab tsi tso cai rau 316L los tuav seb lwm tus swb.
2. Cov pa roj carbon tsawg rau qhov zoo dua weldability
"L" hauv 316L sawv rau cov roj carbon tsawg.
Qhov no me me sib txawv hauv cov ntsiab lus carbon (tsawg dua los yog sib npaug rau 0.03%) ua rau muaj kev pheej hmoo loj- nws txo qhov kev pheej hmoo ntawm carbide nag lossis daus thaum pib siv vuam.
Raws li qhov tshwm sim, 316L tuaj yeem welded thiab fabricated yam tsis tau poob nws corrosion - cov khoom tiv thaiv.
Qhov no yog qhov loj tau zoo hauv kev tsim tshuaj cog qoob loo tsim, yuav tsum muaj qhov chaw vuam dav hlau rau kev tso tsheb hlau luam, cov raj xa khoom, thiab cov nkoj siab.
3.Zeyond corrosion: ib qho zoo -} round ua yeeb yam
Thaum corrosion tsis kam yog lub xov tooj, 316L muaj cov khoom sib npaug ntawm cov khoom uas ua rau nws ua tau zoo:
- Cov neeg kho tshuab zoo -} muaj peev xwm tiv thaiv sab hauv siab, cov khoom tsim tawm, thiab kev ua haujlwm hnyav.
- Zoo heev liricability - Nws tuaj yeem txiav, khoov, machined, thiab welded nrog txheeb ze yooj yim.
- Kev pabcuam dav kub qhov kub thiab txias {{}} tsim nyog rau txhua yam los ntawm ambient cia rau cua sov thiab cua txias.
- Kev tu neeg, du deg - yooj yim ntxuav thiab tiv taus cov khoom lag luam, tseem ceeb hauv kev siv tshuaj thiab cov ntaub ntawv tshuaj.
4.E cas kom huv thiab tswj hwm
Hauv kev lag luam thiab tshuaj lag luam, kev nyiam huv yog qhov tseem ceeb.
316L stainless hlau muaj tus du, tsis - reass}}}}}}}}}} prevows prev prev prevows prevows prevក់ thiab zam kev yooj yim thiab kom tsis muaj menyuam.
Nws feem ntau yog siv nyob rau hauv cov cuab yeej siv tsis tuaj yeem ua kom zoo tsis tau - xws li cov tshuab tso tsheb tso cia, cov raj dej twj tso kua rau.
5...Nws cov ntawv thovtej nyob rau hauv kev ua yeeb yam
Nov yog qee qhov piv txwv uas muaj 316L stainless hlau tau dav siv:
- Tshuaj lom neeg tso tsheb hlau luam thiab cov hlab ntsha siab
- Cov Hluav Taws Xob Tshav Kub Kub thiab Cov Condensers
- Acid aciding thiab hloov pipelines
- Twj, li qub, thiab fittings
- Cov kab distillation thiab evaporators
Nyob rau hauv ntau ntawm cov xwm txheej no, 316L yog xaiv tsis yog rau lub zog, tab sis rau kev ntseeg tau nyob hauv pliaj thiab tsis muaj tshuaj lom neeg.
