    Khoom Ntawv

    Ntawm cangzhou kauv steel yeeb nkab Group Co., Ltd., PebMuab kauv Seam Pipesyog cov khoom lag luam zoo uas ua tau raws li cov qauv kev lag luam siab tshaj plaws. Peb cov kav dej yog tsim rau ntau cov ntawv thov thiab paub txog lawv cov kev ua kom ruaj khov, lub zog thiab corrosion tsis kam.

    Cov pa roj carbon yog qhov yooj yim tshaj plaws hauv cov hlau thiab lub hauv paus rau kev paub qhov txawv ntawm cov hlau. Peb cov kauv seam cov kav dej yog tsim los ntawm cov hlau zoo siab ntawm cov hlau ua kom muaj zog tshaj plaws thiab kav ntev. Nrog lawv cov ntsiab lus carbon ntau cov ntsiab lus, peb cov kav dej yog qhov haum rau cov ntawv thov muaj kev lag luam ntau.

    Ntxiv rau cov pa roj carbon, peb cov kauv leeg coam leeg muaj lwm cov ntsiab lus tseem ceeb xws li npib tsib xee thiab chromium. Nickel yog cov hlau ferromagetic uas ntxiv rau tag nrho lub zog thiab kev coj zoo ntawm cov yeeb nkab. Ib qho ntxiv, nws tiv thaiv corrosion thiab ua kom muaj kev pabcuam ntev dua rau peb kav dej. Chromium, ntawm qhov tod tes, yog qhov tseem ceeb hauv cov hlau tsis xeb thiab muaj cov tshuaj tiv thaiv corrosion. Qhov kev suav ntawm chromium nyob rau hauv peb cov kauv seam pas dej txuas ntxiv lawv txoj kev ua kom ntev thiab ntseeg tau.

    Yeeb Nkab-piles-Astm-A2522

    Ib qho ntawm cov ntsiab lus tseem ceeb ntawm peb cov kauv seam pipes yog lawv cov qauv sib txawv, uas tau ua tiav los ntawm kev siv tshuab vuam wull. Peb lub xeev-ntawm-cov-kos duab sawh (submerged arc kauv vuam) ua rau muaj zog thiab ntev-ntev kev sib txuas hlau daim hlau. Qhov kev siv tshuab vuam no tsis tsuas yog ua kom cov khoom siv tshuab ntawm cov yeeb nkab, tab sis kuj tseem ua kom muaj kev ntws ntawm cov dej ntws lossis roj.

    Peb cov kab kauv seam pipes tau siv dav hauv ntau qhov kev lag luam, suav nrog cov roj thiab roj, tsheb thauj mus los, kev tsim kho thiab kev tsim kho hauv tsev. Nws tuaj yeem ua tiav hauv onshore thiab offshore tej yaam num thiab hauv raj xa hluav taws xob rau cov laj thawj sib txawv. Nrog nws zoo corrosion tsis kam thiab siab tensile lub zog, peb kav dej yog thawj qhov kev xaiv rau cov yeeb nkab vuam nyob rau hauv ib puag ncig.

    a. Cov txheej txheem Deagidation yog tsim raws li hauv qab no:

    FF: Nkaus tua cov hlau uas muaj cov khoom siv nitrogen khi rau hauv cov nyiaj muaj peev xwm khi muaj nitrogen (piv txwv li min lossis 0,015% soluble al).

    b. Tus nqi siab tshaj plaws rau Nitrogen tsis siv yog tias cov tshuaj lom neeg muaj pes tsawg leeg ntawm 0,020% nrog tsawg kawg AL / N piv txog 2: 1, lossis yog tias muaj lwm cov n-khi cov khoom n-khi tam sim no. Cov n-khi cov ntsiab yuav tsum tau sau cia hauv daim ntawv tshuaj xyuas.
