Dab tsi yog Ductile Iron Pipe?
Ductile hlau yeeb nkab yog ib hom cam khwb cia hlau yeeb nkab uas tau txhim kho cov khoom piv rau cov kav hlau cam khwb cia. Nws yog tsim los ntawm kev ntxiv cov khoom alloying, feem ntau magnesium, rau molten hlau ua ntej casting. Cov txheej txheem no ua rau cov yeeb nkab uas muaj zog dua, hloov tau yooj yim, thiab ruaj khov dua li cov kav hlau cam khwb cia.
Cov kav hlau kav dej feem ntau yog siv rau hauv cov dej xa dej rau lawv lub zog zoo dua thiab ua haujlwm ntev. Lawv tuaj yeem tiv taus siab thiab tiv taus corrosion thiab lwm yam kev hnav thiab tsim kua muag. Lawv kuj yog ib qho yooj yim rau nruab thiab tswj, ua rau lawv muaj kev xaiv nrov rau kev tsim kho vaj tse.
Lub neej expectancy ntawm Ductile hlau yeeb nkab yog dab tsi?
Lub neej expectancy ntawm ductile hlau yeeb nkab yog ib qho tseem ceeb xav txog thaum nws los txog rau infrastructure tej yaam num. Kev paub ntev npaum li cas cov yeeb nkab yuav kav ntev npaum li cas pab cov nroog thiab cov chaw siv hluav taws xob npaj rau kev tu thiab hloov, nrog rau cov peev nyiaj rau cov haujlwm yav tom ntej.
Lub neej expectancy ntawm ductile hlau yeeb nkab txawv nyob ntawm ntau yam. Cov yam tseem ceeb no muaj xws li ib puag ncig uas cov yeeb nkab tau teeb tsa, qhov zoo ntawm cov yeeb nkab nws tus kheej, thiab cov yeeb nkab zoo npaum li cas thaum lub sij hawm.
Yam uas cuam tshuam rau lub neej expectancy ntawm Ductile hlau yeeb nkab
1. Ib puag ncig
Ib puag ncig nyob rau hauv uas cov yeeb nkab hlau raug teeb tsa muaj qhov cuam tshuam loj rau nws lub neej expectancy. Cov kav dej nruab rau hauv qhov chaw hnyav, xws li cov uas muaj cov kua qaub lossis cov khoom siv corrosive, yuav deteriorate sai dua cov kav dej uas tau teeb tsa hauv qhov chaw tsis zoo.
Ib yam li ntawd, cov kav dej tau nruab rau hauv thaj chaw uas muaj qhov kub thiab txias hloov pauv, xws li cov uas muaj kev khov thiab thawing cycles, tej zaum yuav ua rau cov kab nrib pleb thiab lwm yam kev puas tsuaj thaum lub sij hawm.
2. Cov yeeb nkab zoo
Qhov zoo ntawm cov yeeb nkab nws tus kheej kuj yog ib qho tseem ceeb hauv kev txiav txim siab nws lub neej expectancy. Cov kav dej uas tau tsim los ua kom tau raws li cov qauv kev lag luam thiab uas dhau los ntawm kev tswj xyuas kev tswj xyuas zoo yog qhov yuav kav ntev dua cov kav dej uas tsis yog.
Cov teeb meem zoo uas tuaj yeem cuam tshuam rau lub neej kev cia siab ntawm cov yeeb nkab hlau muaj xws li porosity, uas tuaj yeem tsim cov chaw tsis muaj zog hauv cov yeeb nkab, thiab kev tsim khoom tsis raug, uas tuaj yeem ua rau tawg lossis lwm yam tsis xws luag.
3. Kev tu
Kev saib xyuas kom zoo yog qhov tseem ceeb los xyuas kom meej tias cov kav hlau kav hlau muaj lub neej ntev. Kev tshuaj xyuas tsis tu ncua tuaj yeem pab txheeb xyuas cov teeb meem uas yuav tshwm sim ua ntej lawv loj tuaj, thiab kev kho kom raws sijhawm tuaj yeem tiv thaiv kev puas tsuaj los ntawm kev sib kis.
Txhawm rau kom lub neej ntev ntawm cov yeeb nkab hlau, nws yog ib qho tseem ceeb rau:
- Ntxuav thiab yaug cov yeeb nkab tsis tu ncua kom tshem tawm cov pob zeb los yog cov pob zeb.
- Saib xyuas qhov xwm txheej ntawm cov yeeb nkab thiab kho qhov kev puas tsuaj sai li sai tau.
Lub neej expectancy ntawm Ductile hlau yeeb nkab
Raws li kev paub txog kev lag luam tam sim no thiab cov kev coj ua zoo tshaj plaws, qhov kev cia siab ntawm lub neej expectancy ntawm ductile hlau yeeb nkab yog nyob nruab nrab ntawm 75 thiab 100 xyoo. Txawm li cas los xij, qhov no tsis yog qhov lav thiab qhov tseeb lub neej expectancy ntawm cov yeeb nkab yuav nyob ntawm seb yam uas tau hais los saum no.
Kev txhim kho kom zoo, cov yeeb nkab zoo, thiab kev saib xyuas tsis tu ncua tuaj yeem pab txuas ntxiv lub neej ntawm cov kav hlau kav ntev tshaj li ntawm 100-xyoo cim, thaum cov kav dej tau nruab rau hauv qhov chaw hnyav lossis kev tswj xyuas tsis zoo yuav tsum tau hloov sai dua.
Vim li no, nws yog ib qho tseem ceeb uas yuav tau ua hauj lwm nrog cov kws tshaj lij los tsim thiab txhim kho cov dej xa dej. Lub nroog thiab cov chaw siv hluav taws xob tseem yuav tsum muaj cov phiaj xwm saib xyuas tsis tu ncua los xyuas kom meej tias cov kav dej tau raug tshuaj xyuas, kho, thiab hloov pauv raws li xav tau.
Xaus
Ductile hlau yeeb nkab yog ib qho kev xaiv nrov rau cov dej faib tshuab rau nws lub zog zoo dua thiab ua haujlwm ntev. Lub neej expectancy ntawm ductile hlau yeeb nkab txawv nyob ntawm ntau yam, nrog rau ib puag ncig nyob rau hauv uas nws yog ntsia, qhov zoo ntawm cov yeeb nkab nws tus kheej, thiab yuav ua li cas zoo nws yog khaws cia nyob rau lub sij hawm.
Thaum lub neej expectancy ntawm cov yeeb nkab hlau yog nyob nruab nrab ntawm 75 thiab 100 xyoo, kev txhim kho kom zoo, cov yeeb nkab zoo, thiab kev saib xyuas tsis tu ncua tuaj yeem txuas lub neej ntawm cov yeeb nkab dhau lub sijhawm no. Lub nroog thiab cov chaw siv hluav taws xob yuav tsum ua haujlwm nrog cov kws tshaj lij thiab muaj cov phiaj xwm saib xyuas tsis tu ncua los xyuas kom meej tias lawv cov dej xa dej ua haujlwm zoo thiab ua haujlwm tau zoo.
