Muaj ntau txoj hauv kev rau kev tshuaj xyuas zoo ntawm cov kab loj-ntev ncaj seam welded steel kav, cov txheej txheem ntawm lub cev kuj tseem siv tau. Kev tshuaj xyuas lub cev yog ib txoj hauv kev uas siv qee qhov tshwm sim ntawm lub cev los ntsuas lossis tshuaj xyuas. Kev tshuaj xyuas ntawm qhov tsis xws luag hauv cov ntaub ntawv lossis cov kab loj-ntev ncaj seam welded steel kav feem ntau siv cov kev sim tsis muaj kev puas tsuaj. Tam sim no tsis muaj kev puas tsuaj xws li kev ntsuam xyuas sib nqus, kuaj ultrasonic, kuaj radiographic, kuaj penetrant, thiab lwm yam.

Sib nqus soj ntsuam
Magnetic flaw detection tsuas tuaj yeem tshawb xyuas qhov chaw thiab qhov ze ntawm qhov chaw ntawm cov hlau nplaum loj-ntev ncaj seam welded steel kav, thiab tsuas tuaj yeem txheeb xyuas qhov tsis xws luag. Qhov xwm thiab qhov tob ntawm qhov tsis xws luag tsuas yog kwv yees raws li kev paub dhau los. Kev soj ntsuam hlau nplaum siv cov sib nqus flux to generated los ntawm magnetic teb los magnetize ferromagnetic loj-inch ncaj seam welded steel kav mus nrhiav qhov tsis xws luag. Cov txheej txheem sib txawv ntawm kev ntsuas qhov sib nqus flux tuaj yeem muab faib rau hauv txoj kev sib nqus particle, magnetic induction method, thiab magnetic recording method. Ntawm lawv, txoj kev sib nqus particle yog dav siv.

Kev tshuaj ntsuam xyuas
Kev tshuaj xyuas Penetrant siv cov khoom siv lub cev xws li permeability ntawm qee cov kua los tshawb pom thiab pom qhov tsis xws luag, suav nrog kev tshuaj xyuas xim thiab tshuaj fluorescence, uas tuaj yeem siv los tshuaj xyuas qhov tsis xws ntawm cov ntaub ntawv ferromagnetic thiab non-ferromagnetic.

Radiographic tshuaj xyuas
Radiographic flaw detection yog ib txoj hauv kev tshawb nrhiav qhov tsis zoo uas siv cov yam ntxwv ntawm cov kab hluav taws xob nkag mus rau cov ntaub ntawv thiab cov khoom siv kom pom qhov tsis xws luag. Raws li cov hluav taws xob sib txawv siv rau kev kuaj pom qhov tsis zoo, nws tuaj yeem muab faib ua peb hom: X-ray flaw detection, gamma-ray flaw detection, thiab high-zog ray flaw detection. Vim muaj ntau txoj hauv kev los nthuav qhia qhov tsis xws luag, txhua hom kev kuaj pom qhov tsis zoo yog muab faib rau hauv txoj kev ionization, fluorescent screen soj ntsuam txoj kev, txoj kev yees duab, thiab kev lag luam hauv TV. Kev tshuaj xyuas hluav taws xob feem ntau yog siv los tshuaj xyuas qhov tsis xws li cov kab nrib pleb, kev nkag tsis tiav, qhov pores, slag inclusions, thiab lwm yam tsis xws luag hauv qhov vuam ntawm qhov loj-inch ncaj seam welded steel kav.

Ultrasonic flaw nrhiav pom
Thaum ultrasonic nthwv dej nthuav tawm hauv cov hlau thiab lwm yam kev tshaj tawm, lawv yuav raug cuam tshuam los ntawm kev sib tshuam ntawm cov xov xwm sib txawv, yog li lawv tuaj yeem siv los tshuaj xyuas qhov tsis xws luag. Ultrasound tuaj yeem kuaj pom qhov tsis xws luag hauv cov khoom siv vuam thiab ib feem, thiab tuaj yeem pom qhov chaw ntawm qhov tsis xws luag, tab sis nws nyuaj rau txiav txim siab qhov xwm txheej, cov duab, thiab qhov loj ntawm qhov tsis xws luag. Yog li ntawd, ultrasonic flaw nrhiav tau ntawm loj-inch ncaj seam welded steel kav feem ntau yog siv nrog rau kev kuaj radiographic.
