1. seamless steel tube magnetic particle testing (MT) lossis magnetic flux to testing (EMI)

Lub hauv paus ntsiab lus ntawm kev tshawb nrhiav yog ua raws li cov khoom siv ferromagnetic yog magnetized nyob rau hauv lub magnetic teb, qhov discontinuity ntawm cov ntaub ntawv los yog cov khoom (tsis xws luag), sib nqus flux to, hlau nplaum hmoov adsorption (los yog kuaj los ntawm detector) tau tshwm sim (los yog tso tawm nyob rau hauv lub ntsuas).Txoj kev no tsuas yog siv tau rau cov khoom siv ferromagnetic los yog qhov chaw nyob ze ntawm qhov chaw kuaj cov khoom.

2. seamless steel raj nkag mus kuaj (PT)

Xws li fluorescent, xim nyob rau hauv ob txoj kev.Vim nws txoj haujlwm yooj yim, yooj yim, yog rau qhov tsis muaj cov khoom siv sib nqus tshuaj ntsuam xyuas txoj hauv kev zoo rau qhov tsis xws luag.Nws yog tsuas yog siv rau kev tshuaj xyuas ntawm qhov tsis xws luag ntawm cov khoom tsis sib nqus.

Lub hauv paus ntsiab lus ntawm fluoroscopy raug kuaj xyuas cov khoom yuav muab tso rau hauv cov kua fluorescent, vim capillary tshwm sim ntawm seamless steel hlab, ntim nrog cov kua fluorescent nyob rau hauv qhov tsis xws luag, tshem tawm cov kua ntawm qhov chaw, vim muaj teeb meem tshwm sim, kua fluorescent hauv qab. ultraviolet teeb pom kev tsis xws luag.

Dye penetrant soj ntsuam ntawm txoj kev xav thiab cov hauv paus ntsiab lus ntawm fluoroscopy zoo ib yam.Tsis xav tau cov cuab yeej tshwj xeeb, tsuas yog siv qhov tsis xws luag Imaging hmoov adsorption hauv cov kua xim hauv qhov pom kev nqus ntawm qhov tsis xws luag.

3. seamless steel yeeb nkab ultrasonic kuaj (UT)

Txoj kev no yog siv ultrasonic vibration los nrhiav cov khoom lossis qhov chaw hauv (lossis nto) qhov tsis xws luag.Nyob ntawm txoj kev ultrasonic vibration tuaj yeem muab faib ua CW thiab pulsed yoj;raws li cov qauv sib txawv ntawm kev vibration thiab propagation yuav muab faib ua p-wave thiab s-wave thiab nto nthwv dej thiab lamb vuag 4 daim ntawv nyob rau hauv lub workpiece kis;raws li qhov sib txawv ntawm lub suab sib kis thiab txais tos, thiab tuaj yeem muab faib ua ib qho kev sojntsuam thiab kev sojntsuam.

4. seamless steel raj rau Eddy tam sim no kuaj (ET)

Eddy tam sim no nrhiav tau ntawm alternating magnetic teb ua rau tib zaus ntawm Eddy tam sim no nyob rau hauv cov hlau, siv Eddy-tam sim no qhov loj ntawm kev sib raug zoo ntawm cov resistivity ntawm cov ntaub ntawv hlau thiab los xyuas qhov tsis xws luag.Thaum muaj qhov tsis xws luag (cracks), qhov kev tiv thaiv yuav ua rau muaj qhov tsis xws luag, cuam tshuam nrog Eddy-tam sim no raug txo qis raws li, kev hloov me me tom qab kev loj hlob ntawm Eddy tam sim no cov cuab yeej qhia, yuav muaj peev xwm qhia tau qhov muaj thiab qhov loj ntawm qhov tsis xws luag.

5. seamless steel raj radiographic kuaj (RT)

Ib qho ntawm cov txheej txheem ntxov tshaj plaws ntawm kev ntsuam xyuas tsis muaj kev puas tsuaj, yog siv dav hauv cov khoom siv hlau thiab cov hlau tsis muaj hlau thiab cov khoom siv rau kev kuaj mob sab hauv, tsawg kawg yog ntau tshaj 50 xyoo keeb kwm.Nws muaj qhov zoo sib xws, xws li kuaj qhov tsis xws luag, kev ntseeg tau thiab kev nkag siab, radiographic thiab yuav raug siv rau kev tshuaj xyuas tsis raug thiab ua cov ntaub ntawv zoo.Tab sis txoj kev no muaj ntau qhov nyuaj, tus nqi siab dua, thiab yuav tsum tau them nyiaj rau kev tiv thaiv hluav taws xob.
