Hauv cov dej num hauv nroog thiab cov dej ntws, cov kav dej hlau ductile yog cov phab ej uas tsis muaj leej twg paub, ua kom cov dej ntws zoo hauv cov nroog. Txawm li cas los xij, ntsib ntau yam kev xaiv zoo kawg nkaus, koj yuav xaiv qhov yog li cas? Tsis txhob txhawj, tus nyeem ntawv! Jindalai Steel Group Co., Ltd. yuav muab rau koj cov lus qhia ntxaws ntxaws txog ntau yam kev qhia ntawm cov kav dej hlau ductile, txij li K9 txog K7, txhua yam koj xav tau.
Ua ntej, cia peb tham txog cov lus nug uas tau nug ntev no: K9 lossis K7? Yog tias koj xav tau cov kav dej uas muaj peev xwm tiv taus qhov siab ntawm cov dej hauv nroog, K9 yog qhov kev xaiv zoo tshaj plaws. Nws zoo li tus superhero ntawm cov kav dej hlau ductile, yooj yim tswj cov chaw muaj siab (≥1.6MPa). K7, ntawm qhov tod tes, zoo li nws tus pab cuam muaj peev xwm, zoo dua rau cov ntawv thov dej ntws nrog qhov xav tau siab dua. Yog li ntawd, yog tias koj xav kom koj cov kav dej hlau ductile kom ua tiav qhov kev ua tau zoo tshaj plaws, ces K9 yog qhov kev xaiv zoo tshaj plaws!
Tam sim no, cia peb tham txog cov ntaub ntawv. Kev nyab xeeb yog qhov tseem ceeb thaum nws los txog rau cov kav dej haus. Tej zaum koj yuav xav tsis thoob tias qhov twg muaj kev nyab xeeb dua, QT450-10 lossis QT500-7. QT500-7 zoo li "tus neeg saib xyuas kev ruaj ntseg" ntawm lub ntiaj teb cov kav dej hlau ductile.—Muaj zog dua, ruaj dua, thiab yog qhov kev xaiv zoo dua rau koj cov dej haus. Yog li, yog tias koj xav kom koj cov dej ntshiab li dej ntws hauv roob, xaiv QT500-7.
Yog li cas txog cov kav dej roj av? Koj puas yuav tsum xaiv cov kav hlau ductile lossis cov kav hlau? Cov lus teb yog: cov kav hlau ductile zoo li tus phooj ywg txhim khu kev qha, ib txwm tuaj txog raws sijhawm. Lawv muaj zog thiab ruaj khov, tuaj yeem tiv taus qhov siab. Cov kav hlau, ntawm qhov tod tes, yog lub teeb thiab yooj yim thauj mus los, ua rau lawv yog qhov kev xaiv zoo hauv qee qhov kev siv. Nws yeej nyob ntawm koj cov kev xav tau tshwj xeeb, tab sis ob qho tib si muaj lawv qhov zoo. Nco ntsoov, nyob rau hauv cov xwm txheej hnyav, cov kav hlau ductile yog qhov kev xaiv txhim khu kev qha!
Tam sim no, cia peb tham txog kev teeb tsa. Thaum nws los txog rau cov kav dej faus, tej zaum koj yuav xav paub tias qhov twg yooj yim dua: cov kav hlau ductile hom qhov (socket-type ductile iron pipes) lossis cov kav hlau ductile flanged. Cov kav hlau hom qhov (socket-type pipes) zoo li tus phooj ywg yooj yim mus, haum rau yuav luag txhua qhov chaw, thiab yooj yim heev rau kev teeb tsa. Cov kav hlau hom flange nyuaj me ntsis, tab sis kev sib txuas ruaj ntseg dua thiab tuaj yeem tiv taus qhov siab siab. Yog li, yog tias qhov yooj yim yog koj qhov tseem ceeb, cov kav hlau hom qhov (socket-type pipes) yog koj qhov kev xaiv zoo tshaj plaws!
Yog li, koj xaiv li cas ntawm cov me me uas muaj teeb meem (≤100 hli) thiab txoj kab uas hla loj (≥800mm) cov kav hlau ductile? Lawv cov qauv xaiv tsuas yog ua rau neeg tsis meej pem xwb. Rau cov kav dej me me, koj yuav tsum tsom mus rau qhov nrawm thiab qhov siab uas yuav tsum tau ua. Rau cov kav dej loj, koj yuav tsum xav txog qhov chaw teeb tsa thiab qhov ua tau ntawm kev xeb.
Thaum nws los txog rau xeb, yog tias koj tab tom cuam tshuam nrog cov kav dej khib nyiab kua qaub thiab alkali, koj yuav raug xaiv ntawm kev siv cov kav hlau ductile ib txwm lossis cov kav dej nrog cov txheej tiv thaiv xeb (xws li epoxy thee tar lossis polyurethane). Cov lus teb yooj yim: xaiv cov kav dej coated! Lawv zoo li lub tsho tiv nag rau cua daj cua dub.—zoo dua muaj kev nyab xeeb dua li thov txim!
Hauv ntej, txawm tias koj xav tau cov kav hlau centrifugal ductile lossis xav txog seb koj yuav xaiv cov chaw muag khoom yeeb nkab hlau twg, nco ntsoov tias Jindalai Steel Group yeej ib txwm yog koj tus neeg txhawb nqa zoo. Nrog cov ntaub ntawv zoo thiab kev lom zem, koj tuaj yeem taug kev hauv ntiaj teb ntawm cov kav hlau ductile nrog kev yooj yim ntawm tus kws tshaj lij. Yog li cia peb tsa khob rau cov phab ej tsis muaj npe uas tau pab txhawb nqa peb txoj kev tsim kho vaj tse.—cov kav hlau uas yoog tau yooj yim! Zoo siab!
