Feem ntau, kev siv passivation muaj qhov cuam tshuam me me piv rau kev siv tshuab, kev sib tsoo lossis kev siv pickling ntau. Txawm li cas los xij, cov khoom ua kom raug yuav tsum qhia meej txog kev kam rau siab, qhov chaw tiav thiab kev tshuaj xyuas ua ntej kho.

Yuav tsum tau thov cov ntaub ntawv dab tsi thaum yuav cov hlau tsis xeb passivated?

Cov ntaub ntawv feem ntau suav nrog daim ntawv xa nqi lag luam, daim ntawv teev cov khoom ntim, EN 10204 3.1 MTC, daim ntawv teev tus lej cua sov, daim ntawv qhia PMI yog tias xav tau, daim ntawv qhia kev tshuaj xyuas qhov ntev, daim ntawv qhia passivation yog tias tau teev tseg, thiab daim ntawv qhia kev tshuaj xyuas sab nraud thaum qhov project xav tau.

Cov Khoom Siv Hlau Stainless Hlau

Rau cov haujlwm uas xav tau kev passivation lossis ntxuav cov nplaim stainless hlau, cov neeg yuav khoom kuj tseem yuav xav txog cov yeeb nkab stainless hlau seamless, cov yeeb nkab stainless hlau welded, stainless hlau puag ncig bar, stainless hlau tiaj tiaj bar, stainless hlau capillary tube, stainless hlau precision tube, stainless hlau flange, stainless hlau yeeb nkab fitting thiab stainless hlau ncej khoom. Cov khoom no tuaj yeem muab tau ntau qib, cov qauv, qhov loj me thiab cov xwm txheej ntawm qhov chaw raws li cov duab kos lossis cov lus qhia yuav khoom.

Kev siv passivation rau cov hlau stainless thiab cov kav dej yog ib qho tseem ceeb rau kev kho qhov chaw kom huv si, txo cov hlau dawb paug thiab txhawb kev tiv thaiv xeb hauv cov ntawv thov kev lag luam uas nyuaj. Nws tsis yog ib txheej thiab tsis hloov pauv cov khoom sib xyaw lossis cov khoom siv kho tshuab, tab sis nws tuaj yeem txo cov teeb meem xeb ntawm qhov chaw uas tiv thaiv tau los ntawm kev ua cov khoom ua qias tuaj.

Rau qhov zoo tshaj plaws, kev siv passivation yuav tsum tau ua ke nrog kev xaiv qib stainless hlau kom raug, cov qauv khoom tsim nyog, kev taug qab tus lej kub txhim khu kev qha, EN 10204 3.1 MTC, kev kuaj PMI thaum xav tau, kev ntim khoom kom raug thiab kev sib txuas lus meej ntawm tus neeg yuav khoom thiab tus neeg muag khoom. Txawm hais tias qhov project cuam tshuam nrog 304 stainless hlau yeeb nkab, 316L seamless yeeb nkab, 2205 duplex bar lossis precision machined stainless hlau Cheebtsam, kev teev cia passivation kom raug tuaj yeem txhim kho kev ntseeg siab ntawm kev yuav khoom thiab kev ua haujlwm ntev.
