Xim ntawmcam khwb cia hlau kavfeem ntau yog hais txog lawv cov kev siv, kev kho corrosion los yog kev lag luam cov qauv. Ntau lub teb chaws thiab kev lag luam tej zaum yuav muaj cov kev cai tshwj xeeb rau cov xim kom muaj kev nyab xeeb, kev tiv thaiv corrosion lossis kev txheeb xyuas yooj yim. Cov hauv qab no yog cov ncauj lus kom ntxaws classification:
1. Lub ntsiab lus dav dav ntawm DINSEN SML yeeb nkab xim
·Dub / tsaus grey/Original cam khwb cia hlau los yog asphalt/anti-corrosion txheej Cov dej ntws, dej phwj tuaj, cov kav dej hauv nroog
·Liab/Cov kav hluav taws kub, kub tsis kam lossis cov cim tshwj xeeb/Hluav taws kub system, dej siab siab
·Ntsuab/Cov kav dej haus, cov txheej txheem ib puag ncig (xws li epoxy resin)/Cov dej haus, khoom noj khoom haus qib dej
·Xiav/Industrial dej, compressed cua/Hoobkas, compressed cua system
·Daj/Gas pipelines (tsawg cam khwb cia hlau, feem ntau steel kav)/Gas kis tau tus mob (qee qhov chaw tseem siv cam khwb cia hlau)
·Nyiaj/Galvanized anti-xeb kho/Sab nraum zoov, ib puag ncig humid, siab corrosion kuj yuav tsum tau
2. Cov kev cai tshwj xeeb rau cam khwb cia hlau yeeb nkab xim hauv kev lag luam hauv tsev thiab txawv teb chaws
(1) Suav lag luam (GB txuj)
Cov kav dej cam khwb cia hlau: feem ntau yog dub (asphalt anti-corrosion) los yog thawj hlau grey, ib nrab coated nrog epoxy resin (ntsuab).
Kev Siv Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob:Ordinary cam khwb cia hlau yeeb nkab: dub lossis liab (rau kev tiv thaiv hluav taws).
Cov yeeb nkab hlau (DN80-DN2600): sab nrauv phab ntsa txau nrog zinc + asphalt (dub), sab hauv nrog cov cement lossis epoxy resin (grey / ntsuab).
Kev Tiv Thaiv Hluav Taws Xob: txheej xim liab, raws li kev tiv thaiv hluav taws kub ntawm GB 50261-2017.
Gas Pipe: daj (tab sis cov kav dej niaj hnub no feem ntau yog ua los ntawm PE lossis steel kav, thiab cam khwb cia hlau tsis tshua siv).
(2) Teb Chaws Asmeskas kev lag luam (AWWA / ANSI Standard)
AWWA C151 (cov yeeb nkab hlau):
Sab nrauv phab ntsa: feem ntau yog dub (asphalt txheej) lossis nyiaj (galvanized).
Sab hauv: cement mortar (grey) lossis epoxy resin (ntsuab / xiav).
Hluav Taws Hluav Taws Xob Hluav Taws Xob (NFPA tus qauv): lub logo liab, qee qhov xav tau cov lus "FIRE SERVICE" luam tawm.
Cov Yeeb Nkab Dej Haus (NSF / ANSI 61 ntawv pov thawj): cov ntaub ntawv sab hauv yuav tsum ua raws li cov qauv kev huv, tsis muaj qhov yuav tsum tau ua rau cov xim phab ntsa sab nrauv, tab sis lub logo ntsuab lossis xiav feem ntau siv.
(3) European lag luam (EN txuj)
TS EN 545 / EN 598 / EN 598 Cov yeeb nkab hlau yeeb nkab
Sab nrauv Anticorrosion: zinc + asphalt (dub) lossis polyurethane (ntsuab).
Sab hauv sab hauv: cement mortar lossis epoxy resin, tsis muaj kev cai xim nruj, tab sis yuav tsum ua raws li cov qauv dej haus (xws li KTW ntawv pov thawj).
Hluav Taws Xob: liab (qee lub teb chaws xav tau luam ntawv "FEUER" lossis "FIRE").
Cov yeeb nkab muaj: tej zaum yuav xiav (compressed cua) los yog daj (gas, tab sis cam khwb cia hlau kav tau maj mam hloov).
(4) Japanese lag luam (JIS tus qauv)
JIS G5526 (cov yeeb nkab hlau): Cov phab ntsa sab nrauv feem ntau yog xim dub (asphalt) lossis galvanized (nyiaj), thiab cov hauv ob sab hauv yog cov cement lossis resin.
Cov yeeb nkab hluav taws: xim liab, qee qhov xav tau luam ntawv "kev tua hluav taws".
Cov kav dej haus: ntsuab lossis xiav hauv kab, raws li JHPA tus qauv.
3. Cov xim ntawm cov xim tshwj xeeb los tiv thaiv corrosion
Epoxy resin txheej: feem ntau yog ntsuab lossis xiav, siv rau kev tiv thaiv corrosion siab (xws li dej hiav txwv, tshuaj lom neeg kev lag luam).
Polyurethane txheej: tej zaum yuav ntsuab, dub los yog daj, muaj zog tiv taus huab cua.
Zinc + asphalt txheej: dub sab nrauv phab ntsa, haum rau cov kav dej faus.
4. Cov ntsiab lus: Yuav ua li cas xaiv cov xim ntawm cov kav hlau cam khwb cia?
Xaiv los ntawm kev siv:
Dej / dej phwj → dub / grey
Haus dej → ntsuab/xiav
Kev tua hluav taws → liab
Kev lag luam → los ntawm kev txheeb xyuas nruab nrab (xws li roj daj, xiav compressed cua)
Xaiv los ntawm tus qauv:
Tuam Tshoj (GB) → dub (kua dej), liab (dub tua hluav taws), ntsuab (dej haus)
Teb chaws Europe thiab Tebchaws Meskas (AWWA/EN) → dub (sab nraud los tiv thaiv corrosion), ntsuab / xiav (hauv ob sab phlu)
Nyiv (JIS) → dub (sab nrauv phab ntsa), liab (tshuaj tua hluav taws)
