Taw qhia txog K7 Ductile Iron Pipe

Cov yeeb nkab hlau ductile qib K7 yog dab tsi? Thiab nws tsim txiaj ntsig li cas rau cov haujlwm engineering thaum ua kom muaj kev nyab xeeb? Niaj hnub no, peb yuav kawm txog qhov no thiab piav qhia vim li cas cov npe lag luam zoo li DINSEN thiaj li dhau los ua cov qauv kev lag luam rau qhov zoo.

Cov kev faib tawm "K" series ntawm cov kav dej hlau ductile. Hauv tus qauv thoob ntiaj teb ISO 2531 thiab tus qauv hauv tebchaws GB / T 13295,cov kav hlau ductileraug muab faib ua K9, K8, K7, K12, thiab lwm yam, raws li phab ntsa tuab. Ntawm no, "K" sawv cev rau cov coefficient ntawm phab ntsa yeeb nkab; tus lej loj dua tom qab K, phab ntsa yeeb nkab tuab dua.

Tau ntev lawm, cov kav dej hlau K9 qib ductile tau yog lub hauv paus tseem ceeb ntawm cov kav dej xa dej vim lawv tiv taus siab. Txawm li cas los xij, hauv kev xyaum ua cov haujlwm txhawb nqa loj hauv tebchaws xws li South-to-North Water Diversion Project, cov kws tshaj lij pom tias rau ntau cov kav dej ntws uas ua haujlwm ntawm qhov siab ntawm kwv yees li 1.0 MPa lossis qis dua, qhov tiv taus siab ntawm cov kav dej K9 qib yog "dhau dhau lawm."K7 cov kav hlau ductiletau siv dav hauv qhov no. Piv rau K9, K7 muaj cov phab ntsa nyias dua, tab sis tswj cov qauv siab hauv cov khoom siv kho tshuab: lub zog tensile ≥420MPa, lub zog tso zis ≥300MPa, thiab qhov nyuaj ≤230HBW. Qhov no qhia tau tias K7 tau ua tiav qhov kev teeb tsa khoom siv zoo tshaj plaws thaum ua tau raws li qhov siab sab hauv thiab cov kev xav tau sab nraud ntawm cov xwm txheej ua haujlwm tshwj xeeb.

Kev xaiv cov kav hlau DINSEN ductile ua koj tus neeg muab khoom K7 txhais tau tias xaiv kev lees paub peb zaug:

1. Kev tswj hwm qhov tuab ntawm phab ntsa thiab cov khoom siv kho tshuab zoo dua;
2. Kev tiv thaiv xeb ua tiav, txuas ntxiv lub neej kev pabcuam;
3. Kev siv tshuab interface yooj ywm thiab kev hloov kho tau.

Vim li cas ho xaiv K7?

• Tus nqi khoom siv raug txo qis. Piv rau K9, K7 muaj phab ntsa nyias dua, ua rau qhov hnyav sib dua rau ib chav ntev ntawm cov yeeb nkab ntawm tib qhov kev qhia tshwj xeeb, txo cov nqi khoom siv raw ncaj qha.
• Cov nqi thauj mus los thiab kev teeb tsa kuj raug txo qis: qhov hnyav sib dua txhais tau tias muaj kev thauj mus los ntau dua ib zaug, thiab kev tsa thiab kev tuav pov hwm ntawm qhov chaw yooj yim dua, ua rau cov nqi ua haujlwm thiab cov tshuab qis dua.
• Kev txuag cov peev txheej kuj tau ua tiav: los ntawm qhov pom ntawm macro, kev xaiv cov kav dej K7 kom zoo txo ​​qhov kev siv cov peev txheej xws li hlau ore thiab coke, ua raws li lub teb chaws ntsuab thiab cov khoom siv hauv tsev qis carbon.

XaivDINSEN cov kav hlau ductiletsis yog tsuas yog xaiv cov khoom siv yeeb nkab xwb, tab sis kuj tseem xaiv tus khub koom tes ua haujlwm uas koom ua ke kev sab laj txog kev siv tshuab, kev muab khoom, thiab kev pabcuam tom qab muag.
