Yuav ua li cas yog txoj kev nrhiav kom tau rojcasing?

1. Ultrasonic kuaj: Thaum ultrasonic tsis kis nyob rau hauv cov ntaub ntawv soj ntsuam, cov kev hloov nyob rau hauv lub acoustic zog ntawm cov ntaub ntawv thiab cov ntaub so ntswg sab hauv muaj ib tug tej yam cuam tshuam rau kev sib kis ntawm ultrasonic tsis.Tom qab kev tshawb fawb ntawm cov degree thiab mob ntawm lub ultrasonic tsis, cov kev hloov ntawm cov khoom thiab cov qauv yog to taub.

2. Ray detection: Cov xov tooj cua-graphic test siv qhov sib txawv ntawm cov hluav taws xob hluav taws xob xa mus los ntawm qhov ib txwm muaj thiab qhov tsis xws luag, thiab qhov sib txawv ntawm cov xim dub ntawm cov yeeb yaj kiab yog tsim.

3. Soak detection: Saturation detection yog siv cov kua capillary nyhuv, cov kua nkag nkag mus rau qhov tsis xws luag ntawm qhov qhib ntawm qhov chaw ntawm cov khoom siv, thiab ces cov nkag nkag mus rau hauv cov kua yog nqus mus rau saum npoo los ntawm tus tsim tawm los qhia txog lub neej. ntawm qhov tsis xws luag.

4. Magnetic particle detection: Magnetic particle detection yog siv cov magnetic flux to at the shortcomings to attract the magnetic powder to form magnetic marks to provide the defects.

5. Eddy tam sim no kuaj: Eddy tam sim no sim siv cov eddy tam sim no induced nyob rau hauv lub workpiece los ntawm ferromagnetic coil los soj ntsuam lub sab hauv zoo ntawm lub workpiece.Nws tuaj yeem txheeb xyuas qhov tsis xws ntawm cov tsos thiab ze ze ntawm ntau yam khoom siv hluav taws xob.Parameter tswj feem ntau nyuaj.

6. Magnetic to detection: Petroleum casing magnetic to detection is based on the features high permeability of ferromagnetic cov ntaub ntawv.Qhov zoo ntawm cov roj av casing hauv kev pabcuam yog kuaj pom los ntawm kev ntsuas qhov permeability los ntawm qhov tsis xws ntawm cov khoom siv ferromagnetic.

7. Magnetic recall detection: Magnetic memory detection yog muab los ntawm kev sib txuas ntawm lub cev ntawm cov hlau sib nqus phenomena thiab cov txheej txheem ntawm dislocations.Nws muaj ntau yam zoo xws li kev ua haujlwm siab, tus nqi qis, thiab tsis tas yuav polishing.Nws muaj cov ntawv thov kev cia siab tseem ceeb hauv kev lag luam.
