Yuav Ua Li Cas Tshawb Xyuas Qhov Zoo Ntawm Kauv Hlau Kav

Tianjin Lefin Industrial Co., Ltd yog ib qho ntawm cov tuam txhab kev paub ntau tshaj plaws thiab cov neeg muag khoom ntawm yuav ua li cas los xyuas qhov zoo ntawm cov kav hlau kav hauv Suav teb. Thov koj xav tias dawb mus yuav cov khoom lag luam zoo li cas los tshuaj xyuas qhov zoo ntawm kauv steel kav los ntawm peb lub hoobkas. Kev pabcuam zoo thiab tus nqi tsim nyog muaj.

Kev tshuaj xyuas qhov zoo ntawm kauv steel kav yog ib txheej txheem txheej txheem uas npog txhua theem ntawm cov khoom siv raw mus rau cov khoom tiav.

Tom qab nkag siab txog lub ntsiab lus tag nrho, peb tuaj yeem nkag siab tob rau hauv ob peb kauj ruam tseem ceeb kom paub meej.

1. Cov khoom siv tshuaj xyuas
High-cov kav hlau zoo pib nrog cov khoom zoo- zoo raw khoom. Qhov kev tshuaj xyuas no yog tsom xyuas kom ntseeg tau tias cov hlau phaj lossis steel coils siv hauv kev tsim cov yeeb nkab ua tau raws li qhov yuav tsum tau ua.

•Kev tshuaj ntsuam xyuas: Siv cov khoom siv xws li spectrometers, cov ntsiab lus ntawm cov khoom xws li carbon, silicon, manganese, sulfur, thiab phosphorus raug soj ntsuam nruj me ntsis kom ntseeg tau tias nws ua raws li cov qauv tsim nyog (xws li API 5L, GB / T 9711).

• Kev ntsuam xyuas cov cuab yeej cuab tam: Lub zog tensile thiab lub zog ntawm cov khoom siv tau los ntawm kev sim tensile, thiab nws qhov qis -kub toughness raug sim los ntawm kev ntsuam xyuas cuam tshuam los xyuas kom meej tias cov hlau muaj lub zog txaus thiab toughness.

• Dimension thiab zoo li kev soj ntsuam: Txheeb xyuas qhov tuab, dav thiab qhov zoo ntawm cov hlau phaj kom tiv thaiv cov khoom siv raw nrog qhov tsis xws luag xws li tawg, voids, xeb hnyav los ntawm kev nkag mus rau hauv cov kab ntau lawm.

2. Kev tshuaj xyuas txheej txheem
Lub hom phiaj ntawm theem no yog ua tiag tiag- lub sijhawm saib xyuas cov txheej txheem vuam thiab qhov zoo ntawm cov yeeb nkab steel tsim, txhawm rau tiv thaiv qhov tsis xws luag tshwm sim.

• Tsis yog -kev kuaj kev puas tsuaj ntawm welds (NDT): Qhov no yog qhov tseem ceeb ntawm cov txheej txheem tshuaj xyuas, thiab nws feem ntau suav nrog:

1. Kev kuaj ultrasonic (UT): Txoj kev no siv ultrasonic nthwv dej los xyuas seb puas muaj qhov tsis xws luag xws li qhov pores, slag inclusions, los yog tsis tiav fusion hauv weld seam. Nws ua rau kev tshawb nrhiav tsis tu ncua thiab tsis siv neeg hauv lub sijhawm tiag tiag -, nrog rau qhov ntsuas pom tau zoo heev.
2. X-rKev tshuaj xyuas (RT):Just zoo li noj "X-ray" ntawm lub vuam seam, nws tuaj yeem muab cov duab meej kom pom qhov tsis xws luag. Rau cov kav hlau uas thauj cov nplaim taws kub hnyiab tau siab - cov kua dej siab, 100% X- feem ntau yuav tsum tau kuaj kab hluav taws xob.
3. Magnetic particle xeem (MT)los yog penetrant testing (PT): Cov hau kev no feem ntau yog siv los xyuas cov kab nrib pleb me me lossis lwm yam tsis xws luag ntawm qhov chaw lossis ze ntawm qhov chaw welds.

• Kev soj ntsuam Geometric dimension: Thaum lub sij hawm tsim khoom, kev ntsuas tas li raug coj mus kuaj lub cheeb, ellipticity, phab ntsa thickness sib txawv thiab qhov ncaj ntawm cov kav dej steel, kom ntseeg tau qhov tseeb geometric qhov ntev.

3. Kev tshuaj xyuas cov khoom tiav
Tom qab cov yeeb nkab steel raug tsim tawm, qhov kawg "check-up" yuav tsum tau kuaj xyuas lawv cov kev ua tau zoo tag nrho.

• Kev kuaj Hydrostatic: Qhov no yog qhov yuav tsum tau ua kom paub tseeb qhov siab -cov kabmob muaj peev xwm thiab kev sib khi ua haujlwm ntawm cov kav hlau. Txhua cov yeeb nkab steel yuav tsum nyob twj ywm raws li qhov ntsuas qhov ntsuas rau qee lub sijhawm, thiab tsis muaj qhov xau yog tias tsis muaj. Kev ntsuas siab feem ntau yog xam raws li cov qauv qauv raws li fcov neeg ua yeeb yam xws li cov khoom siv thiab phab ntsa tuab ntawm cov yeeb nkab steel (piv txwv li, P=2ST/D).

• Kev tshuaj xyuas txheej tiv thaiv corrosion (yog tias tsim nyog): Rau cov kav hlau uas muaj kev tiv thaiv corrosion, lub thickness, adhesion thiab corrosion kuj ntawm cov txheej (xws li epoxy txheej, 3PE) yuav tsum tau kuaj xyuas.

• Kev tshuaj xyuas zaum kawg thiab kev faib tawm: Raws li tag nrho cov txiaj ntsig ntawm kev sim, cov kav hlau kav yog feem ntau muab faib ua peb pawg: cov khoom tsim nyog (ua tau raws txhua qhov ntsuas), cov khoom siv rov ua dua tshiab (muaj cov khoom kho tsis zoo), thiab cov khoom seem (cov khoom tsis zoo uas tsis tuaj yeem kho lossis tsis tsim nyog txawm tias tom qab kho). Txhawm rau txo qhov kev poob qis, "cov khoom siv rov ua dua tshiab" yuav tsum tau rov qab- tshuaj xyuas tom qab kho kom ntseeg tau tias lawv ua tau raws li cov qauv.

Kev soj ntsuam nruj zoo rau cov kav hlau kav yuav tsum tau siv cov qauv ntshiab (xws li API 5L, GB / T 9711, thiab lwm yam), thiab yuav tsum tau ua los ntawm cov neeg ua haujlwm uas tsim nyog siv cov khoom siv txhim khu kev qha.
