Cov Khoom Siv Kho Tshuab:
• Cov Hlau Stainless Duplex muaj kwv yees li ob npaug ntawm lub zog tso zis ntawm lawv cov qib austenitic.
•Qhov no tso cai rau cov neeg tsim khoom siv cov khoom siv nyias dua rau kev tsim lub nkoj!

Duplex stainless hlau zoo dua:
1. Piv nrog cov hlau tsis xeb austenitic
1) Lub zog tso zis yog ntau dua ob npaug ntawm cov hlau austenitic stainless hlau, thiab nws muaj cov yas tawv txaus rau kev txhaj tshuaj. Lub tuab ntawm lub tank lossis lub thawv siab ua los ntawm duplex stainless hlau yog 30-50% qis dua li ntawm cov hlau austenitic stainless hlau feem ntau siv, uas yog qhov zoo rau kev txo tus nqi.
2) Nws muaj kev tiv thaiv zoo heev rau kev ntxhov siab corrosion cracking, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj chloride ions, txawm tias cov duplex alloy nrog cov ntsiab lus qis tshaj plaws muaj kev tiv thaiv siab dua rau kev ntxhov siab corrosion cracking dua li austenitic stainless hlau. Kev ntxhov siab corrosion yog Ib qho teeb meem tseem ceeb uas cov hlau austenitic stainless hlau ib txwm nyuaj rau daws.
3) Cov hlau tsis xeb 2205 duplex feem ntau siv rau hauv ntau yam xov xwm muaj kev tiv thaiv corrosion zoo dua li cov hlau tsis xeb 316L austenitic, thaum cov hlau tsis xeb super duplex muaj kev tiv thaiv corrosion siab. Hauv qee qhov xov xwm, xws li acetic acid thiab formic acid. Nws tuaj yeem hloov cov hlau tsis xeb austenitic siab thiab txawm tias cov hlau tsis xeb.
4) Nws muaj kev tiv thaiv zoo rau kev xeb hauv zos. Piv nrog cov hlau tsis xeb austenitic nrog cov ntsiab lus sib xyaw zoo ib yam, nws muaj kev tiv thaiv kev hnav thiab kev qaug zog corrosion zoo dua li cov hlau tsis xeb austenitic.
5) Cov hlau austenitic stainless hlau muaj cov coefficient qis ntawm kev nthuav dav linear thiab ze rau cov hlau carbon. Nws yog qhov tsim nyog rau kev sib txuas nrog cov hlau carbon thiab muaj qhov tseem ceeb hauv kev tsim kho, xws li kev tsim cov phaj sib xyaw lossis cov ntaub thaiv.

2. Piv nrog rau cov hlau tsis xeb ferritic, qhov zoo ntawm duplex stainless hlau yog raws li nram no:
1) Cov khoom siv kho tshuab zoo dua li cov hlau ferritic stainless hlau, tshwj xeeb tshaj yog cov yas tawv. Tsis rhiab heev rau brittleness li ferritic stainless hlau.
2) Ntxiv rau qhov kev tiv thaiv kev ntxhov siab corrosion, lwm qhov kev tiv thaiv corrosion hauv zos zoo dua li ferritic stainless hlau.
3) Kev ua haujlwm txias thiab kev ua haujlwm txias zoo dua li cov hlau tsis xeb ferritic.
4) Kev ua haujlwm vuam zoo dua li ntawm ferritic stainless hlau. Feem ntau, tsis tas yuav kho cua sov tom qab ua ntej cua sov yam tsis tau vuam.
5) Qhov ntau ntawm daim ntawv thov yog dav dua li ntawm ferritic stainless hlau.

Daim Ntawv ThovVim yog lub zog siab ntawm duplex steel, nws feem ntau txuag cov khoom siv, xws li txo cov phab ntsa tuab ntawm cov yeeb nkab. Kev siv SAF2205 thiab SAF2507W ua piv txwv. SAF2205 yog qhov tsim nyog rau kev siv hauv cov chaw muaj chlorine thiab yog qhov tsim nyog rau kev siv hauv chaw ua roj lossis lwm yam txheej txheem sib xyaw nrog chloride. SAF 2205 yog qhov tshwj xeeb tshaj yog rau kev siv hauv cov cua sov sib pauv uas muaj cov chlorine aqueous lossis dej brackish ua cov khoom txias. Cov khoom siv kuj tseem tsim nyog rau cov kua qaub sulfuric acid dilute thiab cov organic acids ntshiab thiab cov khoom sib xyaw ntawm lawv. Xws li: cov kav dej roj hauv kev lag luam roj thiab roj: desalting ntawm cov roj nyoos hauv cov chaw ua roj, kev ntxuav cov pa roj sulfur, cov khoom siv kho dej khib nyiab; cov tshuab txias siv dej brackish lossis cov kua chlorine.
