Ua kom tsis muaj kev ncaj ncees: Peb Cov Txheej Txheem Txheej Txheem Txheej Txheem Zoo Tshaj Plaws thiab Kev Ntsuas Kev Tiv Thaiv -Corrosion Steel Pipes

Kev ua tau zoo thiab kev ua haujlwm ntev ntawm ib qho kev tiv thaiv- corrosion txheej ntawm cov kav hlau, txawm tias Longitudinally Submerged Arc Welded (LSAW) lossis High-Frequency Welded (HFW), yog qhov kev txiav txim siab los ntawm ob yam tseem ceeb: qhov zoo ntawm qhov kev npaj saum npoo thiab kev nruj ntawm cov txheej txheem kuaj. Ib txheej txheej txheej zoo kawg nkaus siv rau qhov chaw npaj tsis zoo yog destined rau kev ua tsis tiav ntxov, txawm tias daim ntawv thov zoo tshaj plaws tuaj yeem cuam tshuam yam tsis muaj kev txheeb xyuas meej. Ntawm Hebei Huayang Steel Pipe Co., Ltd., peb nkag siab tias kev ncaj ncees ntawm peb cov kav dej tiv thaiv -corrosion steel kav yog qhov tseem ceeb rau kev nyab xeeb thiab kev ntseeg siab ntawm cov txheej txheem tseem ceeb. Yog li, peb yuav ua li cas kom ntseeg tau tias tsis muaj kev ncaj ncees los ntawm peb cov txheej txheem kev npaj saum npoo av thiab kev sim rau kev tiv thaiv -corrosion steel kav? Kab lus no qhia meej txog cov kauj ruam zoo thiab txiav- cov txheej txheem ntug uas peb siv los lav cov txheej txheem zoo tshaj plaws thiab kev tiv thaiv ntev ntev.

Lub hauv paus ntawm kev tiv thaiv: Superior Surface Preparation

Lub adhesion thiab kev ua tau zoo ntawm txhua txheej txheej txheej yog ncaj qha proportional rau kev huv thiab profile ntawm steel nto. Cov kab mob xws li xeb, zeb nplai, roj, thiab cov txheej txheem qub, nrog rau qhov tsis txaus ntawm qhov profile, yuav tiv thaiv kev sib raug zoo thiab ua rau cov txheej txheem ntxov. Peb cov txheej txheem npaj nto ua raws li cov qauv thoob ntiaj teb siab tshaj plaws, feem ntau ISO 8501-1 (Sa 2.5 lossis Sa 3) thiab SSPC-SP cov qauv.

1. Ua ntej-Kev ntxuav thiab degreasing

•Initial Inspection: Cov kav dej raug kuaj pom pom cov khoom paug tag nrho, roj, roj, thiab cov khib nyiab xoob.

•Mechanical Cleaning: Siab -dej siab jetting los yog mechanical txhuam yog siv los tshem tawm xeb, av, thiab lwm yam txawv teb chaws.

•Degreasing: hnyav tu lossis alkaline degreasing yog ua los tshem tawm tag nrho cov kab ntawm cov roj, roj, thiab cov ntsev ntsev, uas tuaj yeem ua rau osmotic blistering hauv qab txheej.

2. Abrasive Blast Cleaning (Grit Blasting)

Qhov no yog cov kauj ruam tseem ceeb tshaj plaws, tsim kom muaj qhov zoo tagnrho rau txheej adhesion.

•Automated Blasting Machines: Cov kav dej tau dhau los ntawm kev siv tshuab moj tej tawg tu tshuab nruab nrog ntau lub turbines uas propel abrasive media (xws li, steel grit, txhaj tshuaj) ntawm siab tshaj tawm mus rau cov yeeb nkab nto.

• Ua tiav Sa 2.5 lossis Sa 3: Cov txheej txheem no tshem tawm tag nrho cov nplai zeb, xeb, thiab cov txheej qub, tsim kom huv, grey-dawb xim hlau. Sa 2.5 (Nyob ze-kev ntxuav hlau dawb) feem ntau yog qhov yuav tsum tau ua yam tsawg kawg nkaus, nrog Sa 3 (White hlau moj tej tawg tu) feem ntau teev rau cov ntawv thov xav tau tshaj plaws.

•Surface Profile (Anchor Pattern): Cov txheej txheem blasting kuj tsim ib qho tshwj xeeb nto roughness, los yog "txheej txheem thauj tog rau nkoj," uas muab ib tug neeg kho tshuab qhov tseem ceeb rau txheej rau ua raws li. Qhov profile qhov tob yog ua tib zoo tswj (feem ntau 50-100 microns) siv profileometers.

3. Kev tshem tawm plua plav thiab xa tawm -Kev tshuaj xyuas tawg

• Nqus Ntxuav / Cua Blasting: Tam sim ntawd tom qab blasting, qhov saum npoo yog huv si kom tshem tawm tag nrho cov abrasive plua plav thiab cov khib nyiab, uas tuaj yeem ua qhov thaiv ntawm cov txheej thiab cov hlau.

• Kev Tshuaj Xyuas Nto: Cov txheej txheem npaj tau raug tshuaj xyuas kom huv, profile, thiab lwm yam tsis xws luag ua ntej txheej txheej. Qhov no feem ntau ua nyob rau hauv cov teeb pom kev zoo tshwj xeeb kom ntseeg tau tias tsis muaj cov kab mob kis tau.

Ua kom muaj kev ntseeg siab ntawm txheej txheej: Kev sim siab heev thiab kev tswj xyuas zoo

Thaum lub npoo tau npaj zoo kawg nkaus, daim ntawv thov txheej nws tus kheej yog nruj me ntsis tswj thiab sim ntawm txhua theem kom ntseeg tau tias nws txoj kev ncaj ncees thiab kev ua tau zoo.

1. Txheej Daim Ntawv Thov Saib Xyuas

• Ib puag ncig tej yam kev mob: Kub, av noo, thiab lwg taw tes yog tsis tu ncua saib xyuas thiab tswj kom zoo zoo daim ntawv thov tej yam kev mob.

• Daim Ntawv Thov Tsis Muaj: Rau FBE, 3LPE, thiab 3LPP, tsis zoo li preheat kub, hmoov / extruder kub, daim ntawv thov ceev, thiab zaj duab xis tuab yog precisely tswj thiab kaw.

2. Tsis yog -Kev kuaj kev puas tsuaj (NDT) ntawm Cov Txheej Txheem

•Dry Film Thickness (DFT) Kev Ntsuas: Tsis yog - ntsuas kev puas tsuaj yog siv los ntsuas cov txheej tuab ntawm ntau lub ntsiab lus raws cov yeeb nkab, kom ntseeg tau tias nws ua tau raws li qhov yuav tsum tau ua (xws li 300-450 microns rau FBE, 2.5-3.7 hli rau 3LPE).

•Hliday Detection (Pinhole Testing): Lub siab -Voltage detector tau hla tag nrho cov coated nto. Txhua tus pinholes, tawg, lossis kev tsis sib xws hauv txheej yuav ua rau muaj hluav taws xob hluav taws xob, qhia txog txoj hauv kev rau corrosion. Qhov kev ntsuam xyuas no yog qhov tseem ceeb rau kev ua kom muaj kev sib txuas tsis tu ncua, impermeable barrier.

• Kev Tshuaj Xyuas Kev Pom Zoo: Cov kws tshuaj ntsuam xyuas pom qhov muag pom tag nrho cov coated nto rau qhov tsis xws luag xws li sags, khiav, hnub so, hlwv, lossis qhov chaw tsis kho.

3. Kev kuaj kev puas tsuaj thiab kev ua tau zoo (Batch / Sample Basis)

•Adhesion Testing: Rub-tawm adhesion xeem (xws li, ASTM D4541) yog ua nyob rau hauv cov qauv yeeb nkab los yog daim coupons xeem kom muaj nuj nqis ntawm daim ntawv cog lus lub zog ntawm cov txheej thiab steel nto.

•Cathodic Disbondment (CD) Test: Qhov kev ntsuam xyuas nrawm no (xws li ASTM G8, ISO 21809-1) ntsuas cov txheej tiv thaiv kom tsis sib haum thaum raug cathodic tiv thaiv tam sim no thiab electrolyte. Nws simulates kev ua tau zoo mus sij hawm ntev hauv qhov chaw faus.

•Impact Resistance Test: Ntsuam xyuas cov txheej txheej muaj peev xwm tiv taus txhua yam tsis muaj kev puas tsuaj (xws li ASTM G14).

•Indentation Hardness Test: Ntsuas cov txheej tiv thaiv kom deformation mus tas li.

•Flexibility/Bend Test: Ntsuam xyuas cov txheej txheej muaj peev xwm nyob twj ywm thiab ua raws li cov yeeb nkab thaum khoov, simulating teb installation.

• Cov Kev Ntsuas Tshuaj Tiv Thaiv Tshwj Xeeb: Rau cov kav dej uas raug rau cov tshuaj tshwj xeeb, kev sim tshwj xeeb rau immersion yog ua.
