ThaumAPI 5L(Line Pipe) tsuas yog qhia ob theem (PSL 1thiabPSL 2), lub sij hawmPSL 3yog nquag siv nyob rau hauvAPI 5 CT(Casing thiab Tubing) thiabAPI 6A(Cov Khoom Siv Hauv Tsev Kho Mob).
Hauv cov ntsiab lus ntawmAPI 5 CT(tus qauv uas cov qib no txawv tshaj plaws), qhov sib txawv ntawm PSL 2 thiab PSL 3 yog qhov tseem ceeb dhia ntawm "zoo" mus rau "khoom kim heev / qhov tseem ceeb." Raws li tus lej PSL nce, qhov yuav tsum tau muaj rau kev sim, tshuaj muaj pes tsawg leeg, thiab traceability ua nruj dua.
Kev tsis ntseeg txog qhov tsim nyog ntawm PSL3 steel kav rau kev ua haujlwm huab cua?Xa koj qhov kev nug, thiab tus engineer yuav muab rau koj nrog tus kheej, ib qho - ntawm - ib qho kev sab laj.
Kev Xeem Xeem (NDT)
PSL 2:Yuav tsum Tsis yog -Kev Ntsuas Kev Ua Phem (NDT) rau feem ntau cov qhab nia, tab sis cov txheej txheem thiab kev pab them nqi yuav raug txwv nyob ntawm qib thiab cov chaw tsim khoom tus qauv kev coj ua.
PSL 3:Yuav tsum muajpuv -lub cev, puv -ntev NDT. Qhov no feem ntau suav nrog kev sib xyaw ntawm Ultrasonic Testing (UT), Sib Nqus Particle Inspection (MPI), lossis Eddy Current. Lub rhiab heev rau kev kuaj pom qhov tsis xws luag yog ntau dua hauv PSL 3 kom ntseeg tau tias tsis muaj cov kab nrib pleb lossis kev sib txuas.
Charpy V-Ntch (Impact) Testing
PSL 2:Kev ntsuam xyuas cuam tshuam yuav tsum muaj rau qee qib thiab qhov ntau thiab tsawg los xyuas kom cov hlau tsis nkig.
PSL 3:Kev sim ntau zaus thiab qhov xav tau ntawm lub zog nqus tau ntau dua. Nws feem ntau yuav tsum tau sim rautxhua qhov kubntawm cov hlau thiab feem ntau ntawm ob qhov kawg ntawm cov yeeb nkab kom ntseeg tau tias muaj kev sib haum xeeb thoob plaws hauv kev tsim khoom.
Phab ntsa Thickness Verification
PSL 2:Phab ntsa tuab yog kuaj xyuas siv cov txheej txheem ntsuas ntsuas lossis kuaj ultrasonic hauv zos.
PSL 3:Yuav tsum muajnruam automated phab ntsa thickness ntsuastshaj tag nrho qhov ntev ntawm cov yeeb nkab. Qhov no ua kom tsis muaj "thin me ntsis" uas tuaj yeem ua rau lub cev qhuav dej hauv qhov siab.
Traceability thiab Identification
PSL 2:Traceability feem ntau yog tswj los ntawm "kub" (cov khoom siv hlau los ntawm cov yeeb nkab tau tsim).
PSL 3:Yuav tsum muajtus kheej cov yeeb nkab traceability. Txhua qhov sib koom ua ke ntawm cov yeeb nkab muaj tus lej cim tshwj xeeb, thiab koj tuaj yeem taug qab cov yeeb nkab tshwj xeeb rov qab mus rau nws qhov chaw nyob hauv qhov chaw, nws qhov kev kho cua sov tshwj xeeb, thiab nws cov txiaj ntsig ntawm tus kheej.
Kho los ntawm Vuam
PSL 2:Qee qhov xwm txheej thiab rau cov qib tshwj xeeb, qhov chaw me me yuav raug kho los ntawm kev vuam (txawm tias qhov no tsis tshua muaj nyob rau niaj hnub OCTG).
PSL 3: Weld kho yog nruj me ntsis txwv.Txhua cov yeeb nkab uas muaj qhov tsis xws luag uas dhau qhov kev zam yuav tsum raug tsis lees paub lossis qhov tsis zoo yuav tsum raug txiav tawm; lub cev ntawm cov yeeb nkab tsis tuaj yeem "patched."
Tshuaj muaj pes tsawg leeg
PSL 3feem ntau imposes nruj "sab hauv" txwv ntawm cov ntsiab lus xws li Sulfur thiab Phosphorus piv rauPSL 2. Txo cov impurities no ua rau cov hlau hnyav dua thiab tiv taus ntau dua rau Stress Corrosion Cracking (SCC), uas yog qhov tseem ceeb rau qhov tob, siab -siab, lossis "qaub" (H2S) qhov dej.

FAQ
PSL-2 txhais li cas ntawm cov yeeb nkab?
PSL-2 stands rau "Product Specification Level 2" nyob rau hauv tus qauv API 5L; nws sawv cev zoo dua thiab cov kev xav tau tshaj li PSL-1 thiab yog siv rau hauv qhov xav tau ntau dua cov roj thiab roj kis ib puag ncig.
PSL 1 yeeb nkab yog dab tsi?
PSL1 yeeb nkab yog lub hauv paus qib ntawm kab yeeb nkab raws li API 5L tus qauv; sawv rau "Product Specification Level 1," nws tsim nyog rau cov kav xa dej thauj cov kua dej- xws li roj, nkev, thiab dej- raws li cov qauv kev ua haujlwm.
