Nyob rau hauv lub teb kev sib hloov zuj zus ntawm kev tsim kho thiab kev siv lag luam, qhov kev thov rau cov khoom siv zoo yog qhov tseem ceeb. Ntawm cov ntaub ntawv no, Hollow ntu qauv kev ua si tau dhau los ua ntau yam kev siv, tshwj xeeb yog nyob rau thaj chaw tsim kho, petrochemicals thiab high-kub boiler tshuab.
Ntawm qhov xub thawj ntawm kev lag luam yog cov chaw tsim khoom lag luam yog nyob rau hauv Cangzhou, Hebei xeev. Tsim tau nyob rau hauv 1993, lub tuam txhab tau nce sai rau ntau xyoo, npog thaj tsam ntawm 350,000 square metres thiab tag nrho cov khoom muaj nqis ntawm 680 lab yuan. Nrog 680 cov neeg ua haujlwm raug mob siab thiab cov cuab yeej zoo tshaj plaws, lub tuam txhab muaj peev xwm ua tau raws li cov neeg siv khoom ntau yam.
Ib qho ntawm cov khoom lag luam muag khoom muaj los ntawm cov chaw tsim tshuaj paus no yog nws ntau ntau ntawm alloy leeg, muaj nyob rau hauv ntau thiab tsawg nyob ntawm 2 nti mus rau 24 nti. Ua los ntawm cov khoom siv high-qib xws li P9 thiab P11, cov leeg no yog qhov zoo rau kev siv hauv qhov chaw kub. Lawv cov ntawv thov loj xws li cov cua sov nyob hauv cov ntsuas cua sov hauv cov ntsuas cua sov, cov lag luam, headers, superheaters, thiab reseaters. Ntxiv mus, cov leeg alloy yog qhov tseem ceeb ntawm kev lag luam petrochemical, qhov twg depababical kev lag luam, qhov twg depability thiab kuj mus rau huab kev mob yog qhov tseem ceeb.
Lub tuam txhab tsim tawmHOLLOW-NTU-NTU COV KAUV TXUJ CI PIPESuas muaj lub zog tshwj xeeb thiab kev ruaj khov rau ntau cov ntawv thov. Lawv cov cim tshwj xeeb tso cai rau cov khoom siv thauj khoom tau zoo, uas yog cov muaj txiaj ntsig tshwj xeeb rau kev ua haujlwm ua haujlwm uas cov qauv kev cai yog qhov tseem ceeb. Txawm hais tias siv hauv kev tsim cov thav duab lossis ua ib feem ntawm cov txheej txheem ua cov nyom, cov leeg no muaj kev cia siab thiab cov kws kos duab uas muaj peev xwm ntseeg tau.
Ib qho ntawm cov ntsiab lus tseem ceeb ntawm hollow ntu ntu qauv cov kav dej yog lawv lub peev xwm los tiv thaiv qhov siab siab thiab kub. Qhov no ua rau lawv zoo tagnrho rau kev lag luam uas xav tau cov ntaub ntawv uas tuaj yeem tiv taus cov xwm txheej hnyav. Hauv kev lag luam petrochemical, piv txwv li, cov kav dej no feem ntau raug rau cov tshuaj uas xeb thiab huab cua sov heev. Cov kav dej alloy muaj los ntawm cov chaw tsim tshuaj paus no tau engineered kom tiv thaiv txoj kev nyuaj no, kom muaj kev pabcuam ntev thiab kev ua haujlwm nyab xeeb.
Tsis tas li ntawd, cov versatility ntawm hollow ntu qauv kev ua yeeb yam tsis muaj txwv rau cov ntawv thov kev lag luam. Lawv kuj tseem nce siv hauv kev tsim qauv architectural, qhov chaw lawv qhov kev thov kom zoo nkauj thiab cov qauv kev zoo tuaj yeem txhim kho qhov tshwm sim tag nrho. Los ntawm cov skyscrapers niaj hnub los tsim cov choj tshiab, cov hlab no tau dhau los ua cov khoom siv tseem ceeb rau cov cuab yeej tam sim no.
Tag nrho hauv txhua qhov, lub hollow ntu style cov khoom tsim los ntawm qhov chaw tsim tshuaj paus no los ntawm cov chaw tsim tshuaj paus no Nrog rau cov khoom lag luam ntawm alloy leeg li 2 nti mus rau 24 ntiv tes, nrog rau qib kev lag luam xws li high-kub boiler tshuab thiab petrochemicals. Raws li qhov kev thov rau cov ntaub ntawv txhim khu kev qha thiab muaj kev kawm tau zoo ntxiv, cov chaw tsim tshuaj no tau npaj txhij los ua kom tau raws li lub ntiaj teb niaj hnub thiab ua kom paub tseeb tias nws cov neeg yuav khoom tau nkag mus rau cov khoom lag luam zoo tshaj plaws. Seb nws siv hauv kev tsim kho, kev siv khoom lag luam lossis kev tsim kho lub tsev tsim qauv, Hollow SectS cov qauv txheej txheem yog qhov tseem ceeb ntawm kev ua ntej ntawm cov cuab yeej tom ntej.
