    Lus piav qhia luv luv:

    Qhia muab kauv welded carbon steel yeeb nkab rau underground natural gas pipeline applications. Cov yeeb nkab zoo no ua raws li EN10219 cov qauv thiab muaj ntau yam txiaj ntsig rau ntau yam kev lag luam thiab kev lag luam siv.


    Product Detail

    Khoom cim npe

    Ib qho ntawm cov txiaj ntsig tseem ceeb ntawmkauv welded carbon steel yeeb nkabyog lub peev xwm los tsim cov kav dej ntawm cov kab sib txawv siv cov strips ntawm tib qhov dav. Qhov no yog qhov tshwj xeeb tshaj yog rau cov ntawv thov uas yuav tsum tau nqaim strips ntawm cov hlau los tsim cov kav hlau loj loj. Cov txheej txheem tsim tshiab no ua kom ntseeg tau tias cov kav dej tsim tsis yog tsuas yog ruaj khov thiab muaj zog, tab sis kuj zoo ib yam.

    Kauv welded carbon steel kav yog tsim tshwj xeeb rau underground natural gas pipeline installation thiab ua raws li cov kev cai nruj.TS EN 10219. Cov txheej txheem no qhia txog cov txheej txheem kev xa khoom rau cov khoom txias-tsim welded structural hollow seem ntawm cov hlau tsis-alloy thiab nplua-grained steels. Cov yeeb nkab yog li no zoo tagnrho rau siv nyob rau hauv underground natural gas pipelines qhov twg corrosion kuj thiab structural kev ncaj ncees tseem ceeb heev.

    ib. Txoj kev deoxidation yog tsim raws li hauv qab no:

    FF: Tag nrho cov hlau uas muaj nitrogen khi cov ntsiab lus hauv cov nyiaj txaus los khi muaj nitrogen (xws li min. 0,020% tag nrho Al lossis 0,015% soluble Al).

    b. Tus nqi siab tshaj plaws rau nitrogen tsis siv yog tias cov tshuaj muaj pes tsawg leeg pom qhov tsawg kawg nkaus Al ntsiab lus ntawm 0,020% nrog qhov tsawg kawg nkaus Al / N piv ntawm 2: 1, lossis yog tias muaj lwm yam N-binding ntsiab. Cov ntsiab lus N-binding yuav tsum tau sau rau hauv Cov Ntaub Ntawv Tshawb Fawb.

    Ntxiv rau nws txoj kev siv ntau yam hauv kev tsim cov kav dej loj loj, cov kav dej welded carbon steel kav muaj ntau lwm yam zoo. Nws cov kauv vuam tshuab ua kom cov yeeb nkab muaj qhov zoo nkauj sab hauv, txo qis kev poob siab thiab txhim kho cov yam ntxwv ntws. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov kev siv roj av, qhov twg muaj txiaj ntsig thiab tsis muaj kev cuam tshuam yog qhov tseem ceeb rau kev ua haujlwm zoo.

    Tsis tas li ntawd, kauv welded carbon steel yeeb nkab yog cov resistant rau corrosion, ua rau nws zoo tagnrho rau underground installations uas raug rau ya raws thiab av ntsiab yuav cuam tshuam qhov ncaj ncees ntawm cov yeeb nkab. Nws cov khoom siv ruaj khov thiab cov khoom siv ruaj khov ua rau nws zoo tagnrho rau kev siv mus ntev hauv kev nyuaj ib puag ncig.

    Kev siv cov pa roj carbon zoo ua kom cov kav dej muaj cov khoom siv zoo heev, suav nrog lub zog tensile siab thiab cuam tshuam. Qhov no ua rau nws muaj kev ntseeg siab xaiv rauunderground natural gas pipekev teeb tsa, raws li cov kav dej yuav raug rau cov khoom siv sab nraud thiab muaj peev xwm puas tsuaj.

    Hauv cov ntsiab lus, kauv welded carbon steel kav yog qhov kev xaiv zoo tshaj plaws rau kev siv roj av hauv av. Nws cov txheej txheem tsim tshiab tso cai rau kev tsim cov kav dej loj loj los ntawm cov kab nqaim ntawm cov hlau, kom ntseeg tau zoo thiab ua haujlwm ntev. Cov yeeb nkab ua tau raws li qhov yuav tsum tau ua ntawm EN10219 tus qauv thiab muaj kev tiv thaiv corrosion zoo heev, du sab hauv thiab cov khoom siv kho tshuab muaj zog, ua rau nws zoo tagnrho rau kev siv mus sij hawm ntev siv nyob rau hauv cov khoom siv hluav taws xob hauv av.
