Kev Tshuaj Xyuas Zoo Ntawm Cov Yeeb Nkab Siab
Nov 08, 2024
- Kev kuaj hluav taws xob hluav taws xob (RT) thev naus laus zis feem ntau yog siv qhov nkag mus ntawm qhov ntsuas hluav taws xob txhawm rau txheeb xyuas seb qhov chaw thiab sab hauv ntawm cov kav dej puas ua raws li cov qauv tsim nyog. Feem ntau siv cov txheej txheem tshuaj ntsuam xyuas hluav taws xob tuaj yeem muab faib ua peb hom: thawj yog txoj kev tshuaj xyuas hluav taws xob, feem ntau siv hauv kev teeb tsa cov kav dej, hauv kev pabcuam siab hauv cov kav dej txuas txuas; qhov thib ob yog txoj kev soj ntsuam xyuas; qhov thib peb yog txoj kev tshuaj xyuas TV, feem ntau yog siv rau hauv kev tsim cov kav dej ntawm cov kav dej uas tsis muaj kev sim siab. Thawj qhov kev pab cuam feem ntau tau txais los ua thawj qhov kev xaiv rau sab hauv NDT ntawm cov kav dej siab welds tom qab ntawm qhov chaw vuam kev tsim kho ntawm cov kav dej siab, uas muaj qhov yooj yim khaws cia ntawm qhov tsis zoo thiab traceability ntawm cov txiaj ntsig, nrog qhov tsis zoo ntawm kev ua haujlwm qis.
- Kev kuaj ultrasonic (UT) thev naus laus zis feem ntau yog siv ultrasonic nthwv dej ntsib ntawm qhov sib cuam tshuam yuav raug cuam tshuam thiab cuam tshuam qhov tshwm sim, thaum dhau los ntawm lub ntsuas hluav taws xob receiver yuav raug cuam tshuam cov teeb liab kom nthuav dav thiab tau txais cov teeb liab tau txais los txheeb xyuas cov teeb liab tau txais, thiaj li paub txog cov teeb liab teeb liab. pipeline hauv qhov tsis xws luag ntawm cov ntaub ntawv. Feem ntau siv nyob rau hauv siab pipeline weld internal defect nrhiav kom tau. Los ntawm cov kev taw qhia ntawm kev pom, ultrasonic tshuaj ntsuam tshuab yog ntau nyuaj rau kev khiav hauj lwm tshaj li radiographic tshuaj ntsuam technology, complex, thiab tsis muaj kev tsis zoo yuav tau txais kev cawmdim.
- Sib nqus particate (MT) thev naus laus zis yog kom magnetise cov raj dej pipeline nyob rau saum npoo ntawm cov raj xa hluav taws xob tau thov cov raj dej, yog li qhia tau cov txoj hauj lwm, qhov loj me, cov duab thiab qhov hnyav ntawm qhov tsis sib xws. Txiav txim seb puas muaj qhov tsis xws luag hauv cov khoom siv kav dej. Feem ntau siv nyob rau hauv kev tshawb nrhiav qhov tsis xws luag ntawm qhov chaw weld thiab ze ze ntawm cov kav dej. Hauv kev siv cov tshuab magnetic particle flaw detection, nws yog ib qho tsim nyog yuav tsum tau sim cov raj xa dej tib lub sij hawm mus rau longitudinal magnetisation thiab transverse magnetisation, thiaj li yuav zoo lav tag nrho cov kev tshawb nrhiav. Siab pipeline engineering, feem ntau magnetic particle flaw detection li ferromagnetic siab pipeline weld nto, fillet weld non-destructive testing txhais tau tias, tab sis tsis siv rau nickel-based alloys thiab stainless hlau thiab lwm yam ntaub ntawv uas tsis yog-magnetic.
