Vim li cas Casing Quality Tests Matters
Roj casing yog ib qho tseem ceeb ntawm cov roj drilling. Nws txhawb nqa cov phab ntsa zoo, tiv thaiv phab ntsa kom zoo thiab tswj hauv qab zoo siab thaum lub sijhawm drilling, ua tiav thiab ntau lawm. Ib qho tsis xws luag hauv lub cev los yog nws cov kev sib txuas tuaj yeem ua rau cov dej ntws tawm, tawg lossis txawm tias poob ntawm lub qhov dej, yog li kev tshuaj xyuas zoo ntawm cov roj casing yog qhov tseem ceeb los xyuas kom meej tias muaj kev nyab xeeb thiab ua haujlwm zoo ntawm kev ua haujlwm drilling. Casing yog tsim los rau API 5CT, thiab qhov kev tshuaj ntsuam xyuas ua ke ua ke qhov loj me, qhov muag pom, txhua yam, siab thiab tsis yog - kev kuaj kev puas tsuaj.
Kev tshuaj xyuas qhov tshwm sim
Kev tshuaj xyuas qhov tshwm sim yog ib qho kev kuaj xyuas zoo tshaj plaws. Los ntawm kev ua tib zoo saib xyuas qhov chaw ntawm lub casing, cov neeg soj ntsuam xyuas cov kab nrib pleb, deformation, corrosion, pits, laps thiab lwm yam teeb meem. Nyob rau tib lub sijhawm, cov kev sib txuas threaded raug kuaj xyuas kom tiav, xov puas thiab vuam tsis xws luag nyob qhov twg, vim hais tias kev sib txuas yog qhov nyuaj tshaj plaws ntawm cov hlua casing.
Dimensional ntsuas
Kev ntsuas qhov ntev yog ib feem tseem ceeb ntawm kev kuaj xyuas qhov zoo. Siv cov cuab yeej xws li calipers, vernier calipers, micrometers, ring gauges thiab plug gauges, cov neeg soj ntsuam ntsuas cov kab sab nraud, phab ntsa thickness, ntev, tawm - ntawm - roundness thiab xov qhov ntev los xyuas kom meej tias lub casing ua tau raws li tus qauv tsim thiab cov qauv yuav tsum tau ua. Dimensional conformity yog qhov tseem ceeb rau qhov tseeb ua- ntawm cov xov txuas thiab kev tshem tawm hauv qhov drilled.
Kev kuaj khoom
Cov khoom siv kuaj xyuas kom paub tseeb tias lub casing chemistry thiab cov qauv ua tau raws li tus qauv. Cov txheej txheem feem ntau suav nrog kev tshuaj xyuas tshuaj muaj pes tsawg leeg, tshuaj xyuas cov qauv metallographic thiab kuaj hardness. Cov kev kuaj xyuas no tau lees paub tias cov khoom sib xyaw ntawm cov khoom ua tau raws li qhov yuav tsum tau ua ntawm API 5CT rau qib txiav txim, thiab tias cov microstructure zoo li qub thiab ntom tom qab kev kho cua sov.
| Kuaj | Lub hom phiaj |
|---|---|
| Tshuaj ntsuam xyuas | Txheeb xyuas cov ntsiab lus carbon, manganese thiab alloy raws li qib txwv |
| Kev ntsuas tensile | Paub meej tias yield thiab tensile lub zog rau qib txiav txim |
| Kev sim hardness | Txheeb xyuas qhov sib xws thiab kuaj xyuas qhov tawv tawv heev |
| Metallography | Txheeb xyuas cov qauv nplej thiab kev kho cua sov |
Kev Ntsuas Siab
Roj casing yuav tsum tiv taus siab sab hauv thiab sab nraud thaum lub sij hawm drilling thiab ntau lawm, yog li kev ntsuas siab yog ib qho tseem ceeb ntawm kev soj ntsuam zoo. Lub casing yog ntsia rau ntawm cov cuab yeej kuaj tshwj xeeb, ib qho kev ntsuas tshwj xeeb yog siv thiab tuav, thiab cov yeeb nkab raug soj ntsuam rau kev xau, deformation lossis tsis ua haujlwm. Qhov kev sim hydrostatic ua pov thawj tias lub casing tuaj yeem tiv taus qhov kev xav tau ua haujlwm siab thiab qhov kev sib txuas raug kaw kom raug.
Tsis yog -Kev kuaj kev puas tsuaj
Tsis yog -kev kuaj kev puas tsuaj pom qhov chaw thiab sab hauv qhov tsis zoo yam tsis muaj kev puas tsuaj rau cov yeeb nkab.
Kev ntsuam xyuas cov khoom sib nqus yog siv los txheeb xyuas cov kab nrib pleb thiab lwm yam tsis xws luag ntawm lub cev lub cev thiab hauv tshav kub- thaj chaw cuam tshuam. Cov hmoov hlau nplaum yog siv rau saum npoo thaum siv cov hlau nplaum, thiab cov hmoov sib nqus ntawm cov kab nrib pleb lossis qhov tsis xws luag los qhia lawv qhov chaw thiab qhov twg.
Kev ntsuam xyuas Penetrant siv cov capillary nkaus ntawm cov kua dej nkag, uas nkag mus rau qhov chaw qhib qhov chaw thiab tom qab ntawd kos tawm los ntawm tus tsim tawm los qhia lawv. Nws yog tsim rau ntau yam hlau workpieces, tsuas yog siv li ntawm ib nrab ib teev los ntawm daim ntawv thov mus rau qhia, thiab tuaj yeem kuaj xyuas qhov qaug zog, kev ntxhov siab corrosion thiab vuam tawg, nrog rau ntsuas qhov tawg ncaj qha.
Kev kuaj ultrasonic thiab kev kuaj hluav taws xob kuaj pom muaj qhov tsis xws luag xws li suav nrog, laminations thiab voids, thiab kev tshuaj ntsuam xyuas hluav taws xob, suav nrog eddy tam sim no thiab sib nqus flux to, yog dav siv raws li tag nrho - kuaj lub cev ntawm seamless casing thaum lub sij hawm tsim khoom, raws li xav tau rau ntau qib API 5CT.
Zaus, Qauv thiab Txais
Kev xeem zaus yog txhais los ntawm API 5CT thiab daim ntawv xaj khoom. Kev kuaj pom thiab qhov loj me yog ua los ntawm qhov tseem ceeb hauv txhua cov yeeb nkab, kev ntsuas hydrostatic yog siv raws li tus qauv nrog cov qauv lossis tag nrho - kuaj lub cev nyob ntawm qib thiab qhov loj, thiab tsis yog- kev kuaj xyuas kev puas tsuaj yog siv rau 100 feem pua ntawm cov yeeb nkab lub cev rau seamless casing hauv feem ntau qib. Thaum cov qauv ua tsis tiav, cov lus qhia tshwj xeeb txhais cov cai rov kuaj dua, thiab cov cua sov lossis ntau yuav raug rov ua dua- sim lossis tsis lees paub. Tag nrho cov txiaj ntsig tau raug kaw rau ntawm daim ntawv pov thawj zeb xeem rau tag nrho traceability ntawm txhua lub tshav kub thiab cov yeeb nkab.
Cov lus nug nquag
Tus txheej txheem twg tswj cov roj casing zoo?
API 5CT yog kev tswj xyuas tshwj xeeb rau cov casing thiab tubing, txhais cov qib, tshuaj lom neeg thiab cov khoom siv, thiab kev tshuaj xyuas thiab kev sim rau txhua qib.
Puas yog kev sim hydrostatic ua rau ntawm txhua lub kav dej?
API 5CT yuav tsum tau kuaj hydrostatic ntawm txhua cov yeeb nkab rau feem ntau cov qib, nrog rau tshwj xeeb tshwj xeeb tau teev tseg hauv tus qauv. Kev ntsuas siab yog xam los ntawm cov yeeb nkab qhov ntev thiab qib thiab raug kaw rau ntawm daim ntawv pov thawj.
Dab tsi yog qhov txawv ntawm qhov sib nqus particle thiab kev ntsuam xyuas penetrant?
Kev ntsuam xyuas cov khoom sib nqus yuav tsum muaj cov khoom siv hlau nplaum thiab kuaj pom qhov chaw thiab nyob ze - qhov chaw deg nyob rau hauv lub magnetic teb, thaum kev ntsuam xyuas penetrant ua hauj lwm nyob rau hauv tej yam uas tsis yog - ntxeem tau nto thiab ntes qhib defects los ntawm capillary ua.
Kev kuaj ultrasonic puas tuaj yeem pom cov teeb meem sab hauv hauv casing?
Yog lawm, kev kuaj ultrasonic kuaj pom muaj qhov tsis xws luag xws li suav nrog, laminations thiab phab ntsa- thickness discontinuities, thiab feem ntau yog ua ke nrog electromagnetic tshuaj xyuas kom puv - lub cev kev pab them nqi.
Vim li cas kev tshuaj xyuas xov tseem ceeb rau casing?
Cov threaded kev twb kev txuas yog qhov kev nyuab siab tshaj plaws ntawm txoj hlua thiab yuav tsum tau muab khi rau hauv siab. Xov puas, galling los yog qhov yuam kev ntawm qhov loj tuaj yeem ua rau kev sib txuas tsis ua haujlwm, yog li cov xov raug ntsuas thiab pom pom ua ntej xa khoom xa tuaj.
Cov ntaub ntawv dab tsi pov thawj casing zoo?
Daim ntawv pov thawj zeb xeem sau cov cua sov, qib, tshuaj ntsuam xyuas, tensile cov txiaj ntsig, kev ntsuas hydrostatic siab thiab cov txiaj ntsig ntawm qhov tsis yog -kev kuaj xyuas kev puas tsuaj, muab tag nrho traceability los ntawm steelmaking mus rau cov yeeb nkab xa.
