    Ntxiv nrog rau cov pa roj carbon monoxide, peb cov hlua khi hlua khi muaj lwm cov ntsiab lus tseem ceeb xws li npib tsib xee thiab chromium.Nickel yog ferromagnetic hlau uas ntxiv rau tag nrho lub zog thiab polishability ntawm cov yeeb nkab.Tsis tas li ntawd, nws tiv thaiv corrosion thiab ua kom lub neej ua haujlwm ntev rau peb cov kav dej.Chromium, ntawm qhov tod tes, yog ib qho tseem ceeb hauv cov hlau tsis muaj steel thiab muaj kev tiv thaiv corrosion zoo heev.Kev suav nrog chromium nyob rau hauv peb cov kav hlau txuas txuas ntxiv ua rau lawv lub neej ntev thiab kev ntseeg tau.

    Cov yeeb nkab-Piles-ASTM-A2522

    Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm peb cov kav hlau txuas txuas yog lawv cov qauv tsim seamless, uas tau ua tiav los ntawm kev siv vuam thev naus laus zis.Peb lub xeev-of-the-art SAWH (Submerged Arc Spiral Welding) vuam tshuab ua kom muaj kev ruaj khov thiab kav ntev ntawm cov yeeb nkab steel phaj.Qhov kev siv tshuab vuam no tsis yog tsuas yog txhim kho cov khoom siv ntawm cov yeeb nkab, tab sis kuj ua kom lub ntsej muag du, uas ua rau muaj txiaj ntsig zoo ntawm ntau yam kua los yog roj.

    Peb cov kav dej spiral seam tau siv dav hauv ntau qhov kev lag luam, suav nrog roj thiab roj, kev thauj mus los hauv dej, kev tsim kho thiab kev tsim kho vaj tse.Nws tuaj yeem siv rau hauv cov dej num sab nrauv thiab sab nrauv thiab hauv cov kav dej rau ntau lub hom phiaj.Nrog nws zoo heev corrosion kuj thiab siab tensile zog, peb cov kav dej yog thawj qhov kev xaiv rau cov yeeb nkab vuam nyob rau hauv ib puag ncig hnyav.

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

    FF: Ua tiav cov hlau uas muaj nitrogen khi cov ntsiab lus kom 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.

    Ntawm Cangzhou Spiral Steel Pipe Group Co., Ltd., peb muab qhov zoo thiab cov neeg siv khoom txaus siab ua ntej.Peb cov kws tshaj lij pab neeg ua haujlwm tau ua kom ntseeg tau tias txhua lub kav hlau txuas txuas tau ua tiav cov txheej txheem tswj xyuas kom ua tau raws li cov qauv thoob ntiaj teb.Tsis tas li ntawd, peb muab ntau yam kev xaiv txheej txheej rau cov kav dej, suav nrog epoxy, polyethylene thiab cement mortar, txhawm rau txhim kho cov yeeb nkab corrosion kuj thiab txuas ntxiv nws lub neej kev pab cuam.
