Cov Yeeb Nkab Hlau Ductile Hnyav Npaum Li Cas

Hauv kev tsim kho dej thiab kev ntws dej, cov kav dej hauv nroog, thiab cov kav dej hauv kev lag luam,cov yeeb nkab hlau ductiletau dhau los ua ib qho kev hloov pauv zoo tshaj plaws rau cov kav dej hlau thiab cov kav hlau ib txwm muaj vim nws cov khoom siv kho tshuab zoo heev thiab kev tiv thaiv corrosion. Kev nkag siab txog cov yam ntxwv tseem ceeb ntawm cov kav dej hlau ductile yog qhov tseem ceeb rau cov neeg tsim qauv, cov neeg yuav khoom, thiab cov tuam txhab tsim kho, txawm tias rau cov kav dej xa dej lossis kev thauj mus los ntawm dej phwj. Tsab xov xwm no yuav siv sijhawmDINSEN cov yeeb nkab hlau ductileua piv txwv los piav qhia txog nws cov lus qhia, qhov hnyav, kev ua haujlwm siab, thiab cov yam ntxwv ntawm txheej.

I. Cov Lus Qhia thiab Qhov Loj ntawm Cov Yeeb Nkab Hlau Ductile: Yuav Ua Li Cas Txheeb Xyuas Tus Qauv?

Thaum xaiv cov kav dej, ua ntej tshaj plaws yuav tsum tau piav qhia meej txog qhov loj thiab qhov ntev ntawm cov kav dej hlau ductile. Cov qauv thoob ntiaj teb feem ntau yog raws li ISO 2531 lossis EN 545, faib ua pawg raws li txoj kab uas hla nominal (DN).

Piv txwv li, siv cov yeeb nkab DINSEN ductile iron, cov yeeb nkab K9 qib (qib phab ntsa tuab) feem ntau siv, nrog rau cov kab uas hla ntawm DN80 txog DN2000. Nov yog qee qhov loj ntawm cov yeeb nkab:

• DN80: Sab nraud txoj kab uas hla 98 hli, phab ntsa tuab 6.0 hli
• DN100: Sab nraud txoj kab uas hla 118 hli, phab ntsa tuab 6.0 hli
• DN200: Sab nraud txoj kab uas hla 222mm, phab ntsa tuab 6.3mm
• DN400: Sab nraud txoj kab uas hla 429mm, phab ntsa tuab 8.1mm
• DN1000: Sab nraud txoj kab uas hla 1048mm, phab ntsa tuab 13.5mm

Cov qib tuab ntawm phab ntsa sib txawv (K8, K9, K10, K12) yuav cuam tshuam rau lub peev xwm siab thiab qhov hnyav ntawm cov yeeb nkab.. Cov neeg siv khoom tuaj yeem xaiv tau raws li qhov tsim siab.

II. Qhov hnyav ib 'meter' ntawm cov yeeb nkab hlau ductile: Cov yeeb nkab hlau ductile hnyav npaum li cas?

Ib lo lus nug uas nquag nug hauv kev yuav khoom siv engineering yog: Cov yeeb nkab hlau ductile hnyav npaum li cas? Qhov hnyav ntawm cov yeeb nkab hlau ductile muaj qhov hnyav ntawm lub cev yeeb nkab thiab qhov hnyav ntawm lub qhov (socket), uas cuam tshuam ncaj qha rau kev thauj mus los, kev tsa, thiab cov nqi teeb tsa.

Piv txwv li, siv DINSEN K9 qib ductile hlau yeeb nkab (tus qauv ntev 6 meters) ua piv txwv, qhov hnyav theoretical yog raws li nram no:

• DN100: Kwv yees li 15.1 kg/m → 95 kg ib lub yeeb nkab
• DN200: Kwv yees li 30.6 kg/m → 194 kg ib lub yeeb nkab
• DN300: Kwv yees li ntawm 50.8 kg/m → 323 kg ib lub yeeb nkab
• DN500: Kwv yees li ntawm 104.3 kg/m → 669 kg ib lub yeeb nkab
• DN800: Kwv yees li ntawm 215.2 kg/m → 1394 kg ib lub yeeb nkab

Qhov hnyav tiag tiag yuav txawv me ntsis vim muaj tej yam xws li qhov tuab ntawm zinc txheej thiab sab hauv ntawm cov cement mortar. DINSEN tuaj yeem muab cov ntawv xam qhov hnyav raug rau kev npaj nyiaj txiag thiab kev npaj logistics.

III. Kev Ua Haujlwm Siab ntawm Cov Yeeb Nkab Hlau Ductile

Cov yeeb nkab hlau ductile muaj lub zog tensile siab thiab lub zog compressive ncig. Cov yeeb nkab hlau ductile qib K9 feem ntau muaj lub zog ua haujlwm ntawm 16 bar (1.6 MPa), thaum cov qib tuab phab ntsa siab dua (xws li K12) yog qhov tsim nyog rau kev siv lub zog ntawm 25 bar lossis txawm tias 40 bar.

Cov kav dej hlau ductile DINSEN raug tsim tawm raws li ISO 2531 tus qauv. Txhua lub kav dej raug kuaj hydrostatic ua ntej tawm hauv lub Hoobkas kom ntseeg tau tias muaj kev nyab xeeb siab dua 1.5 npaug ntawm qhov siab ua haujlwm tsim, ua rau lawv tsim nyog rau kev xa dej mus deb, cov kav dej twj tso kua mis, thiab cov kav dej siab siab.

IV. Txheej Zinc rau Kev Tiv Thaiv Kev Xeb

Lub Luag Haujlwm ntawm Zinc Txheej rau Cov Kav Dej Hlau Ductile Ib qho ntawm cov kev tiv thaiv tseem ceeb tshaj plaws rau cov kav dej faus yog zinc txheej rau cov kav dej hlau ductile. Cov zinc txheej tsis yog tsuas yog muab kev tiv thaiv cathodic xwb tab sis kuj tsim cov txheej txheem tiv thaiv xeb sib xyaw nrog cov xim sab nraud lossis polyethylene sheathing.

Cov kav dej hlau DINSEN muaj cov txheej zinc ≥200 g/m² (raws li tus qauv ISO 8179), npog nrog cov txheej epoxy asphalt liab lossis polyurethane tiav, ua rau kev tiv taus corrosion thiab lub neej ntev dua. Rau cov av corrosive lossis thaj chaw uas muaj kev tiv taus siab, muaj cov txheej zinc ntxiv + PE zaj duab xis lossis txheej polyurethane tag nrho, nrog lub neej tsim los ntawm 50-100 xyoo.

V. Vim li cas ho xaiv DINSEN Ductile Iron Pipes?

Ua ib lub tuam txhab muab cov yeeb nkab hlau ductile, DINSEN muaj ntau yam kev qhia tshwj xeeb los ntawm DN80 txog DN2000, txhawb nqa ntau yam phab ntsa tuab xws li K8, K9, K10, thiab K12, thiab tuaj yeem kho qhov ntev, cov ntaub sab hauv (cement mortar / epoxy resin), thiab cov kev daws teeb meem tiv thaiv xeb sab nraud kom tau raws li cov neeg siv khoom xav tau.

Txhua cov kav dej hlau ductile yog ISO 2531 / EN 545 daim ntawv pov thawj. Cov lus qhia tiav ntawm qhov hnyav, qhov ntev, kev ua haujlwm siab, thiab cov txheej txheem zinc muaj. Kev ntim khoom xa tawm thoob ntiaj teb thiab kev pabcuam logistics ib qho chaw nres tsheb tau txais kev txhawb nqa.

Yog xav paub ntxiv txog qhov loj thiab qhov ntev ntawm cov yeeb nkab ductile lossis cov cuab yeej xam qhov hnyav, thov mus saibDINSENlos yog tiv tauj pab pawg muag khoom ncaj qha.
