Nkag Siab Txog Cov Kav Hlau Uas Muaj Qhov Coob: Cov Lus Qhia Tshwj Xeeb, Cov Kev Siv, thiab Cov Qauv Thoob Ntiaj Teb

Cov kav dej hlau ductile tau dhau los ua lub hauv paus tseem ceeb hauv cov khoom siv niaj hnub no, tshwj xeeb tshaj yog hauv kev faib dej thiab cov txheej txheem tswj dej khib nyiab. Paub txog lawv lub zog thiab kev ruaj khov, cov kav dej no tau tsim los ua kom tau raws li ntau yam qauv, suav nrog ASTM A536 specification, uas qhia txog cov kev cai rau cov khoom siv yeeb nkab hlau ductile. Ntawm ntau qib sib txawv muaj, K9 qib yeeb nkab hlau ductile yog qhov tshwj xeeb tshaj yog rau lawv cov khoom siv kho tshuab zoo dua, ua rau lawv haum rau kev siv siab. Lub yeeb nkab hlau ductile DN800, nrog lub cheeb tsam nominal ntawm 800 millimeters, yog qhov kev xaiv nrov rau cov haujlwm loj, muab kev daws teeb meem txhim khu kev qha rau kev thauj dej thiab lwm yam kua dej.

Kev siv cov kav dej hlau ductile muaj ntau yam, txij li cov dej hauv nroog mus rau cov kev siv hauv kev lag luam. Lawv txoj kev tiv thaiv corrosion thiab muaj peev xwm tiv taus siab siab ua rau lawv zoo tagnrho rau ob qho tib si saum av thiab hauv av. Tsis tas li ntawd, cov kav dej hlau ductile feem ntau siv rau hauv cov tshuab tiv thaiv hluav taws, qhov twg kev ntseeg siab yog qhov tseem ceeb. Qhov ua tau ntau yam ntawm cov kav dej no tso cai rau lawv siv rau ntau qhov chaw, suav nrog thaj chaw hauv nroog, thaj chaw nyob deb nroog, thiab txawm tias thaj chaw nyuaj. Thaum cov nroog txuas ntxiv loj hlob thiab kev xav tau ntawm cov khoom siv hauv paus tsev nce ntxiv, qhov xav tau cov kev daws teeb meem kav dej ruaj khov thiab ua haujlwm tau zoo xws li cov kav dej hlau ductile tseem ceeb dua.

Thaum tham txog qib kev faib tawm ntawm cov kav hlau ductile, nws yog ib qho tseem ceeb kom nkag siab txog qhov tseem ceeb ntawm cov qib sib txawv. Piv txwv li, qib K9 yog tsim los tswj cov qib siab dua piv rau cov qib qis dua, ua rau nws haum rau cov ntawv thov uas muaj kev pheej hmoo ntawm kev nce siab. Cov lus qhia ntawm cov kav hlau ductile, suav nrog phab ntsa tuab thiab txoj kab uas hla, yog qhov tseem ceeb hauv kev txiav txim siab lawv cov kev ua tau zoo hauv ntau yam xwm txheej. Kev sib raug zoo ntawm txoj kab uas hla nominal thiab siab kuj yog qhov tseem ceeb uas yuav tsum xav txog; thaum txoj kab uas hla nce ntxiv, qhov ntsuas siab yuav tsum tau soj ntsuam kom zoo kom ntseeg tau tias lub kaw lus muaj kev ncaj ncees. Kev sib raug zoo no yog qhov tseem ceeb rau cov kav dej loj dua, xws li DN800 ductile hlau yeeb nkab, uas yuav tsum tau tsim los tswj cov khoom siv hydraulic loj.

Raws li qhov kev thov thoob ntiaj teb rau cov kav dej hlau ductile txuas ntxiv nce siab, cov tuam txhab zoo li Jindalai Steel Company yog cov thawj coj hauv kev tsim kho tshiab thiab kev tsim khoom. Nrog kev cog lus rau qhov zoo thiab kev ruaj khov, Jindalai Steel Company tau tsim nws tus kheej ua tus thawj coj hauv kev tsim cov kav dej hlau ductile, ua raws li cov qauv thoob ntiaj teb thiab cov kev coj ua zoo tshaj plaws. Lub tuam txhab tsom mus rau kev tshawb fawb thiab kev txhim kho kom ntseeg tau tias lawv cov khoom ua tau raws li qhov xav tau ntawm kev ua lag luam, thaum tseem daws cov teeb meem ib puag ncig. Raws li cov haujlwm tsim kho vaj tse thoob ntiaj teb tau muab qhov tseem ceeb rau kev ruaj khov thiab kev ua haujlwm zoo, lub luag haujlwm ntawm cov kav dej hlau ductile, tshwj xeeb tshaj yog cov uas ua tau raws li tus qauv A536 thiab K9 qib specifications, yuav tsis muaj qhov tsis ntseeg tseem ceeb hauv kev tsim cov dej yav tom ntej ntawm kev tswj hwm dej thiab kev faib khoom.

Xaus lus, cov kav hlau ductile, tshwj xeeb tshaj yog cov uas tau muab faib ua ASTM A536 thiab K9 qib, yog cov khoom tseem ceeb hauv cov khoom siv niaj hnub no. Lawv daim ntawv thov siv rau ntau yam lag luam, thiab kev nkag siab txog lawv cov lus qhia thiab cov yam ntxwv ua tau zoo yog qhov tseem ceeb rau cov engineers thiab cov thawj coj project. Raws li cov tuam txhab zoo li Jindalai Steel Company txuas ntxiv tsim kho tshiab thiab tsim cov kav hlau ductile zoo, kev lag luam tuaj yeem cia siab tias yuav pom kev nce qib uas txhim kho kev ntseeg siab thiab kev ua haujlwm ntawm cov khoom siv tseem ceeb no.
