Ductile Iron Push On Pipe

Ductile hlau laub rau cov yeeb nkab, tseem hu ua laub yeeb nkab, (ductile hlau jacking yeeb nkab) muaj cov yam ntxwv hauv qab no:

Ductile hlau jacking yeeb nkab yog ib hom ductile hlau yeeb nkab uas tuaj yeem nteg tsis tau khawb trenches thiab tuaj yeem raug thawb los ntawm kev kov yeej kev sib txhuam ntawm cov av los ntawm kev thawb lub zog. Thaum siv, lub cev yeeb nkab feem ntau raug thawb rau hauv av thiab tom qab ntawd thawb rov qab. Lub cev yeeb nkab thib ob txuas nrog rau thawj cov yeeb nkab lub cev, thiab ntau lub yeeb nkab lub cev raug thawb ua ntu zus los ua kom tiav cov haujlwm ejection. Cov yeeb nkab ntau lub cev yog butted kawg mus rau qhov kawg los tsim cov yeeb nkab jacking ua haujlwm

1, Interface hom thiab phab ntsa thickness qib; phab ntsa tuab qib ntawm jacking yeeb nkab Ntau dua los yog sib npaug rau K 8 los yog qib siab sib xws;

2, T-shaped ductile hlau jacking yeeb nkab qauv:

3. Lub ntsiab kev ntxhov siab-cov kabmob qhov chaw yog: qhov (socket) nto thiab flange kawg nto.

4. Interface daim ntawv: Siv slide-in interface txuas.

5. Feem ntau muab faib ua T-hom interface thiab K2T-hom interface.

Cov yeeb nkab txoj kab uas hla ntawm T-hom interface yog: DN600 ~ DN2600

Txoj kab uas hla ntawm K2T hom interface yog: DN1600 ~ DN2600

6. Lub interface foob txais lub nplhaib tshwj xeeb roj hmab sealing. Los ntawm xws li optimized tsim, sealing kev ua tau zoo thiab corrosion kuj ntawm lub raj xa dej yog zoo guaranteed.

7. Ntxiv rau cov kav dej, kev teeb tsa cov kav dej kuj suav nrog cov yeeb nkab fittings, roj hmab nplhaib, bolts, ceev thiab lwm yam khoom siv.

Ductile hlau jacking yeeb nkab tau maj mam dhau los ua cov khoom siv hauv cov yeeb nkab tseem ceeb hauv cov txheej txheem ntawm cov hlau jacking yeeb nkab, feem ntau vim tias nws muaj qhov zoo hauv qab no:

1. Kev ua haujlwm zoo los tiv thaiv corrosion: Cov khoom siv hlau nplaum nws tus kheej muaj kev tiv thaiv corrosion zoo. Nws cov phab ntsa sab nrauv yog txau nrog zinc txheej (130g / m2) thiab qhwv los ntawm 6 ~ 10 cm tuab reinforced pob zeb. Ib qho epoxy resin txheej kuj tseem siv rau sab nrauv phab ntsa ntawm lub tsho pob zeb, uas tsis yog tsuas yog txhim kho corrosion kuj, tab sis kuj txo cov kev sib txhuam ntawm cov yeeb nkab thiab cov av. Qhov muaj peev xwm tiv thaiv corrosion super ua kom ntseeg tau tias lub neej kev pab cuam ntawm cov hlau thawb ntawm cov yeeb nkab tuaj yeem ntev li 70-100 xyoo.

2. Nrog rau lub zog loj loj: Los ntawm kev teeb tsa cov flanges, txhawb cov tav thiab encapsulating reinforced pob zeb, qhov tso cai thrust quab yuam ntawm cov kav dej yog nce. Piv txwv li, qhov tso cai thawb lub zog ntawm K9 qib DN1200 ductile hlau thawb ntawm cov yeeb nkab tuaj yeem ncav cuag 739 tons. Ntxiv mus, cov khoom uas muaj kev tso cai ntau dua tuaj yeem tsim tau los ntawm kev nce phab ntsa thickness ntawm lub raj yam tsis muaj kev nce nqi loj.

3. Kho kom haum rau nkhaus yeeb nkab jacking kev tsim kho: Lub interface ntawm ductile hlau thawb ntawm cov yeeb nkab tso cai rau lub deflection lub kaum sab xis ntawm Greater los yog sib npaug rau 1.5 degree, uas ua rau nws lug siv nyob rau hauv nkhaus yeeb nkab jacking siv.

4. Muab cov kav dej nrog cov qhov grouting thiab sib thooj grouting qhov sealing ntsuas kom tau raws li cov kev xav tau tshwj xeeb thaum tsim kho.

5. Kev sib txhuam qis qis: Lub zog sib txhuam nrog cov av me dua, uas yog qhov tsim nyog rau jacking cov yeeb nkab hauv av los ntawm ntu.

Ntim:

Cov yeeb nkab txoj kab uas hla hauv qab 300mm yog bundled nrog steel strips, thiab cov kav dej siab tshaj 300mm tau ntim rau hauv ntau.
