| Kev Ntsuas Tam Sim No ntawm Cov Hlau Stainless Steel |
Kev kuaj tam sim no eddy yog ib txoj kev kuaj tsis ua puas tsuaj (NDT) siv los nrhiav qhov tsis zoo ntawm qhov chaw thiab ze ntawm qhov chaw hauv cov kav hlau tsis xeb. Cov txheej txheem no zoo tshwj xeeb rau kev txheeb xyuas cov kab nrib pleb, qhov, thiab lwm yam kev tsis sib txuas yam tsis ua rau cov khoom puas tsuaj. Los ntawm kev ua kom muaj lub zog hluav taws xob hauv lub raj thiab saib xyuas kev hloov pauv ntawm cov dej ntws eddy, cov neeg soj ntsuam tuaj yeem soj ntsuam qhov kev ncaj ncees ntawm phab ntsa raj sai sai. Kev kuaj tam sim no eddy yog siv dav hauv kev tsim cov kav hlau tsis xeb thiab vuam, tshwj xeeb tshaj yog rau cov khoom siv hloov pauv cua sov, boiler, thiab cov cuab yeej siv. Nws ua kom ntseeg tau tias cov khoom muaj kev ntseeg siab thiab ua raws li cov qauv kev lag luam xws li ASTM E426 thiab EN 10246-3.
| Kev Ntsuas Cov Ntsiab Lus Ferrite |
Kev kuaj cov ntsiab lus Ferrite yog ib qho txheej txheem tswj xyuas zoo tseem ceeb rau cov kav dej hlau tsis xeb, tshwj xeeb tshaj yog cov uas ua los ntawm austenitic lossis duplex qib. Qhov kev xeem tsis puas tsuaj no ntsuas qhov ntau ntawm ferrite theem uas muaj nyob rau hauv cov khoom siv yeeb nkab lossis thaj chaw vuam kom ntseeg tau tias muaj kev tiv thaiv corrosion zoo tshaj plaws, kev ua haujlwm kho tshuab, thiab kev ncaj ncees ntawm vuam. Cov ntsiab lus ferrite ntau dhau lossis tsis txaus tuaj yeem ua rau muaj teeb meem xws li kev ntxhov siab corrosion tawg lossis txo qhov tawv. Kev kuaj feem ntau yog ua los ntawm kev siv cov txheej txheem magnetic induction (piv txwv li, Ferrite Scope), thiab ua raws li cov qauv xws li ASTM E562, ISO 8249, lossis AWS A4.2. Hauv cov kav dej siv hauv cov chaw tseem ceeb - xws li cov platforms offshore, cov hlab ntsha siab, thiab cov nroj tsuag tshuaj - kev tswj cov ntsiab lus ferrite yog qhov tseem ceeb rau kev ntseeg siab thiab kev nyab xeeb mus sij hawm ntev.

| Kev daws teeb meem online Annealing ntawm Stainless Steel Tubes |
Kev siv online solution annealing yog ib txoj kev kho cua sov tas mus li uas siv rau cov kav hlau stainless thaum lub sijhawm tsim khoom kom txhim kho lawv txoj kev tiv taus xeb, lub zog kho tshuab, thiab kev sib xws ntawm cov qauv me me. Hauv cov txheej txheem no, cov kav hlau raug cua sov sai sai mus rau qhov kub ntawm kev daws teeb meem - feem ntau ntawm 1000 ° C thiab 1150 ° C - ua raws li kev tswj hwm txias, feem ntau siv dej lossis roj inert. Kev kho no yaj cov carbide precipitates thiab rov qab kho cov qauv austenitic, uas yog qhov tseem ceeb rau cov qib zoo li 304 thiab 316. Los ntawm kev koom ua ke cov kauj ruam no ncaj qha rau hauv kab ntau lawm, kev siv online solution annealing ua kom muaj qhov zoo sib xws, txhim kho kev ua haujlwm zoo, thiab tshem tawm qhov xav tau kev sib cais annealing.
