Thaum siv Stainless Hlau Hnab, corrosion yuav tshwm sim vim muaj kev cuam tshuam ntawm ib puag ncig sab hauv lub raj dej lossis ib puag ncig sab nraud. Yog li cov hau dab tsi uas peb tuaj yeem siv los xyuas nws thaum tu txhua hnub? IECY, tus kws pab tswv yim tswv yim ntawm Zhejiang mingli Yeeb Nkab Lag Luam, yuav coj koj mus kawm kom meej.
1. Raug manifestations ntawm corrosion ntawm stainless hlau lauj
(a) thinning ntawm phab ntsa tuab:
Vim tias ntev - lub sij hawm elosion, cov khoom siv tsis zoo li thinned, uas ua rau muaj kev txo txhua feem lossis ib feem ntawm qhov taub.
(b) cov pits hauv zos thiab pits:
Irregular saum npoo tsis xws luag tsim vim yog nruab nrab yaig, electrochemical corrosion, thiab lwm yam.
(c) cov txheej txheem struction:
Cov anti - corrosion txheej los yog tawg, ua rau cov hlau sib dhos thiab ua kom muaj zog.
2. Nkag siab txog dab tsi yuav tshwm sim tom qab stainless hlau luj tshib yog corroded. Tam sim no peb nkag siab qee txoj kev pom thiab cov ntsiab cai rau kev xeb ntawm cov hlau stainless
Sib Nqus Tseem Ceeb Nrhiav Kom Tau Txoj Cai thiab Txoj Cai
(a) Sib nqus flux flux (mfl) txoj kev (tseem hu ua kev sib nqus kev kawm paub txoj kev)
Lub hauv paus ntsiab lus: muaj kev sib nqus permeability ntawm cov ntaub ntawv ferromagnetic
Lub luj tshib yog magnetized hauv qab qhov kev txiav txim ntawm ib qho kev sib nqus sab nraud sib nqus. Nyob rau hauv qhov puas - qhov chaw pub dawb, cov sib nqus kab flux kis dhau ntawm cov yeeb nkab phab ntsa ense. Nyob rau hauv thaj chaw corroded, cov sib nqus permethability txo qis, ua rau lub sib nqus grages flux kab kom khoov thiab xau ntawm "kev sib nqus ugricet". Nyob rau lub sijhawm no, lub cim sib nqus gragin flux tau ntes los ntawm sensor los txiav txim qhov chaw, qhov loj me thiab qhov loj ntawm qhov tsis xws luag.
Cov txiaj ntsig zoo: Nws tuaj yeem lees paub sai sai cov chaw corrosion thiab ntsuas qhov corrosion degree, uas haum rau feem ntau ntawm cov ntawv tais.
NCO TSEG: Nco ntsoov tias lub luj tshib yog cov sib xyaw ua ke sib nqus thaum kuaj.
(b) Kev Ntsuas Ultrasonic (ut) txoj kev
Lub ntsiab cai: Ultrasonic mem tes yuav rov qab
Qhov kev sojntsuam emits ultrasonic pulses ntsug mus rau sab hauv phab ntsa ntawm lub luj tshib loj thiab tau txais echo pulses los ntawm sab hauv thiab sab nraud chaw. Lub sijhawm luv ntawm ob lub echhoes yog sib npaug rau cov phab ntsa tuab, yog li cov phab ntsa tuab ntawm lub luj tshib luj tshib loj tuaj yeem suav raws li lub sijhawm no. Hom no tseem siv tau los tshawb xyuas seb cov phab ntsa tuab ntawm cov khoom sib ntsib tus qauv thaum nws tawm ntawm lub hoobkas.
Cov txiaj ntsig zoo: nws muaj peev xwm raug ntsuas ntawm phab ntsa tuab, muaj cov kev daws teeb meem siab, thiab tuaj yeem txheeb xyuas qhov tsis xws luag corrosion.
Muaj feem rau ntau yam khoom siv (cov hlau thiab tsis - hlau) thiab tuaj yeem hloov kho cov geometry ntawm lub luj tshib.
Nco tseg: Coupant yog qhov yuav tsum tau, lub tiaj tiaj ntawm lub luj stainless hlau Luj nqis yog qhov siab, thiab qhov kev ntsuas ceev yog cuam tshuam los ntawm kev ua haujlwm ntawm phau ntawv.
(c) ntsuas hluav taws xob (RT) txoj kev
Lub hauv paus ntsiab lus: siv lub retenuation txawv thaum x {{0} {{{{1}- rays chim cov khoom siv
Thaum lub ray hla dhau thaj chaw corrosion ntawm lub luj tshib ntawm lub luj tshib, qhov kev ua kom tsawg dua vim yog lub taub hau tuab ntawm lub luj tshib hauv thaj chaw no. Ib qho sib txawv sib txawv yog tsim rau ntawm zaj duab xis lossis ntes los qhia cov duab thiab thaj chaw ntawm qhov tsis xws luag.
Cov txiaj ntsig zoo: Intuitively display cov duab kho mob tsis zoo, haum rau stainless hlau thrbows nrog cov ntaub ntawv ntsuas nyuaj, thiab tuaj yeem muab cov ntaub ntawv xeem ua haujlwm tas mus li.
Nco tseg: Kev tiv thaiv hluav taws xob nruj me ntsis yuav tsum muaj thiab tus nqi yog siab. Kev ua tau zoo yog tsawg rau nyias-}} walled lauj kaub thiab tsis haum rau kev sim online.
(d) eddy kev sim tam sim no (ect) txoj kev
Lub hauv paus ntsiab lus: induction induction
Kev sib sib yuav ua kev sib nqus sib nraus tsim hluav taws xob Eddy tawm ntawm cov npoo ntawm lub luj tshib luj tshib. Qhov loj me ntawm eddy tam sim no yog cuam tshuam nrog kev ua haujlwm thiab tuab ntawm cov khoom siv. Lub corrosion qhov tsis xws ntawm lub teel hlau lauj tshib yuav hloov kho Eddy kev txiav txim siab tam sim no, thiab cov kev txiav txim siab raug txiav txim los ntawm kev hloov pauv ntawm cov kauj voltage.
Qhov Zoo: Kev Ntsuas Ceev, Tsis Muaj Kev Yooj Yim, haum rau saum npoo thiab ze - qhov tsis xws luag.
Nws yog qhov ua tau zoo dua rau qhov tsis - ferrigagnetic cov ntaub ntawv (xws li stainless hlau luj tshib) thiab tsis tshua muaj cuam tshuam los ntawm curvers.
CEEB TOOM: Kev tshawb nrhiav qhov tob yog tsawg (feem ntau<5mm), and it is difficult to evaluate the deep corrosion of stainless steel elbows.
(e) Kev pom kev pom (vt) txoj kev
Lub hauv paus ntsiab lus: ncaj qha saib cov corrosion ntawm lub luj tshib saum lub luj tshib nrog lub qhov muag liab qab lossis cov tsom iav Endoscopes (xws li endoscopes, magnesifyatify).
Cov txiaj ntsig zoo: kev ua haujlwm yooj yim, tus nqi qis, thiab tuaj yeem txheeb pom sai sai rau qhov tsis xws luag).
Cov Lus Cim: Cia siab rau kev paub ntawm tus kuaj xyuas, nws yog tsis yooj yim sua kom pom kev xeb sab hauv lossis cov chaw zais ntawm cov hlau stainless tshib.
3. Cov xwm txheej sib txawv kom peb siv cov qauv sib txawv lossis sib txuas ntau txoj hauv kev.
Kev ntsuas kev tshawb nrhiav online: Sib nqus flux flux) thiab ultrasonic thickness ntsuas (tre)
Kev ntsuam xyuas qhov tseeb: Rotcegraphic Nrhiav tau (RT) thiab hluav taws xob nrhiav kom paub cov ncauj lus kom pom tseeb ntawm cov hlau tsis muaj zog ntawm lub sijhawm kaw thiab txij nkawm.
Daim Ntawv Sib Sau Kom Paub: Piv txwv, "Sib Nqus Flux xau thiab Kev Ntsuas Cov Qauv Ultrasonic txhawm rau txhim kho kev nrhiav kom tau kev ua tau zoo thiab raug.
Kev tshawb fawb tshawb xyuas cov qauv thiab ua ke nrog cov kev ua haujlwm tiag tiag ntawm cov kab mob stainless thiab hloov chaw, thiab ua haujlwm kom muaj kev nyab xeeb ntawm lub system.
