DN550 steel yeeb nkab yog hais txog cov yeeb nkab steel ntawm ib qhov loj me, qhov "DN" yog cov ntawv luv ntawm "Diameter Nominal", uas txhais tau tias "nominal diameter". Nominal txoj kab uas hla yog tus qauv siv los qhia qhov loj ntawm cov kav dej, cov yeeb nkab fittings, thiab li qub. Hauv kev lag luam steel yeeb nkab, dab tsi yog txoj kab uas hla ntawm DN550 steel yeeb nkab? Cov lus teb yog hais txog 550 mm.

Hlau yeeb nkab yog ib hom hlau yeeb nkab ua los ntawm steel thiab yog dav siv nyob rau hauv kev tsim kho, machinery manufacturing, petrochemical, hluav taws xob fais fab, aerospace, thiab lwm yam teb. Cov yeeb nkab steel muaj qhov zoo ntawm lub zog siab, corrosion kuj, thiab kub tsis kam, yog li nws tau siv dav hauv ntau yam haujlwm thiab kev siv.

Ntxiv nrog rau qhov loj ntawm cov kab hlau sab nraud ntawm DN550 steel yeeb nkab, peb tuaj yeem nkag siab qee qhov tseem ceeb ntawm cov yeeb nkab steel, xws li phab ntsa thickness, ntev, thiab cov khoom siv.

1. Phab ntsa thickness: Phab ntsa thickness yog hais txog lub thickness ntawm cov yeeb nkab steel, feem ntau qhia nyob rau hauv millimeters los yog nti. Cov phab ntsa thickness ntawm cov yeeb nkab steel yog ze ze rau nws txoj kab uas hla, thiab sib txawv daim ntawv thov scenarios thiab cov kev cai kuj muaj cov kev cai sib txawv rau phab ntsa thickness.
2. Ntev: Qhov ntev ntawm cov kav hlau steel feem ntau yog tus qauv, thiab qhov ntev ntev xws li 6 meters, 9 meters, 12 meters, thiab lwm yam. Tau kawg, nyob rau hauv cov kev xav tau tshwj xeeb, qhov ntev kuj tuaj yeem kho raws li cov neeg siv khoom xav tau.
3. Khoom siv: Muaj ntau yam khoom siv rau cov kav hlau, thiab cov khoom siv feem ntau yog carbon steel kav, stainless hlau kav, alloy steel kav, thiab lwm yam. Cov ntaub ntawv sib txawv muaj cov yam ntxwv sib txawv thiab siv tau. Thaum xaiv cov kav dej steel, nws yog ib qho tsim nyog yuav tsum xaiv qhov tsim nyog raws li kev siv tshwj xeeb.

Tom qab nkag siab cov ntaub ntawv tseem ceeb ntawm cov kab hlau sab nraud ntawm DN550 steel yeeb nkab, peb tuaj yeem tshawb xyuas ntxiv qee cov ntsiab lus ntsig txog cov kav hlau steel, xws li kev tsim khoom, kev siv, thiab kev xav tau ntawm kev lag luam.
1. Cov txheej txheem tsim khoom: Cov txheej txheem tsim cov kav hlau steel feem ntau suav nrog cov kav dej seamless thiab welded kav. Seamless kav yog tsim los ntawm cua sov steel billet rau ib tug tej yam kub thiab ces ncab los yog perforating nws. Lawv muaj lub zog siab thiab sealing. Welded kav yog tsim los ntawm khoov steel daim hlau rau hauv cov duab tubular thiab ces welding lawv. Cov txheej txheem tsim khoom yog qhov yooj yim thiab tus nqi qis.
2. Kev Siv: Cov kav hlau steel muaj ntau yam kev siv. Lawv tuaj yeem siv los thauj cov kua, roj, thiab cov khoom siv, thiab tseem tuaj yeem siv los tsim ntau yam qauv thiab kev txhawb nqa. Piv txwv li, nyob rau hauv kev lag luam petrochemical, cov kav hlau siv dav siv los thauj cov roj, roj av, thiab cov khoom siv tshuaj lom neeg; nyob rau hauv kev tsim kho kev lag luam, steel kav yog siv los tsim steel qauv, txhawb nqa stairs load-bearing phab ntsa, thiab lwm yam.
3. Kev lag luam xav tau: Nrog rau kev txhim kho kev lag luam thiab kev lag luam kev lag luam, kev lag luam xav tau rau cov kav hlau steel tau nce xyoo los ntawm xyoo. Tshwj xeeb tshaj yog nyob rau hauv kev tsim kho vaj tse, kev tsim kho nroog, thiab kev tsim kho kev lag luam, muaj kev xav tau loj rau cov kav dej steel. Yog li ntawd, cov yeeb nkab steel kev lag luam yeej ib txwm yog ib qho kev lag luam uas muaj peev xwm thiab kev sib tw.

Hauv cov ntsiab lus, sab nraud ntawm DN550 steel yeeb nkab yog li 550 hli. Nws yog ib hom steel yeeb nkab specification thiab yog dav siv nyob rau hauv ntau yam teb. Cov neeg nyob hauv kev lag luam steel yuav tsum nkag siab txog cov ntsiab lus ntawm cov kav hlau steel, uas yuav pab xaiv cov kav hlau zoo thiab ua tiav cov txiaj ntsig zoo tshaj plaws hauv kev siv tswv yim. Nrog rau txoj kev loj hlob ntawm kev lag luam thiab kev nce qib ntawm kev siv thev naus laus zis, kev lag luam steel yeeb nkab yuav txuas ntxiv kom loj hlob thiab ua tau raws li qhov xav tau ntawm cov kav hlau steel hauv ntau qhov chaw. Cia peb tos ntsoov rau kev lag luam steel yeeb nkab tsim kom muaj kev txhim kho yav tom ntej!
