Hauv tsab xov xwm no koj yuav kawm txog API 5L Kab kav dej. Qhov tshwj xeeb ntawm API 5L npog seamless thiab welded kav rau thauj cov roj, roj, dej hauv cov roj & roj thiab petrochemical industries.
API qhia los ntawm American Petroleum Institute (API) API-5L tus qauv thaum ntxov xyoo 1926, pib muaj peb qib ntawm steel A25, A, B, thiab hloov kho ob peb zaug tom qab. API 5L welded steel yeeb nkab yog siv feem ntau rau kev muab khoom ntawm onshore thiab offshore roj thiab roj, thee slurry, slurry media thiab offshore platforms, fais fab nroj tsuag, tshuaj lom neeg thiab kev tsim kho hauv nroog, cov hlab ntsha.
API 5L Carbon Steel Pipes specifications ua raws li ISO 3183 International Organization for Standardization, uas standardizes pipeline tsheb thauj mus los systems rau roj av, petrochemical thiab natural gas industries nyob rau hauv cov ntaub ntawv, khoom siv thiab offshore qauv. Pawg Neeg Saib Xyuas Kev Ua Haujlwm tau lees paub tias muaj ob theem pib Cov Khoom Qhia Tshwj Xeeb (PSL) ntawm cov kev cai thiab yog li tsim PSL 1 thiab PSL 2. PSL 1 yog tus qauv zoo rau kab yeeb nkab uas PSL 2 muaj cov tshuaj ntxiv, cov khoom siv kho tshuab, thiab xeem cov cai.
Cov qhab nia them los ntawm qhov kev qhia tshwj xeeb no yog A25, A, B (thiab cov qib "X" hauv qab no), X42, X46, X52, X56, X60, X65, X70, X80. Tus lej ob tus lej tom qab "X" qhia qhov Tsawg Tshaj Tawm Lub Zog (hauv 000's psi) ntawm cov yeeb nkab uas tsim rau qib no.
API 5L Line Pipe ntau lawm tam sim no siv cov txheej txheem kho cua sov micro-alloy. Cov nqi tsim khoom ntawm seamless stainless hlau yeeb nkab yog qhov siab dua li cov yeeb nkab vuam thiab nrog kev nce qib ntawm cov hlau, qhov txwv ntawm cov ntsiab lus carbon yog ntau thiab nruj dua. Tam sim no, tag nrho cov tuam txhab lag luam loj tau ua haujlwm tshawb fawb txhawm rau txhim kho corrosion kuj ntawm cov kav dej thiab ua kom muaj kev ruaj khov ntawm qhov kub thiab txias.
API 5L cov kav dej tuaj yeem raug cais raws li cov hauv qab no:
Kev ua tiav: seamless lossis welded (cov kav dej seamless yuav siv tau txog 24 ntiv tes, LSAW saum 24 ntiv tes, ERW txog 20 ntiv tes)
Qib Specification (API PSL1, PSL2): PSL1 yog tus qauv zoo siv rau cov kav dej, qhov PSL2 teeb tsa cov tshuaj nruj dua, cov khoom siv kho tshuab, thiab cov kev xeem
Deg tag: dub, kua roj vanish pleev xim rau, anti-xeb roj, galvanized, coated externally (3PL) thiab / los yog lined nyob rau hauv
xaus hom: tiaj, beveled, threaded xaus
Qhov zoo ntawm API 5L yeeb nkab yog:
Tiv thaiv kom tawg rog uas tuaj yeem nthuav tawm hauv cov kav dej ntev
Sour kev pabcuam tsim nyog
Theej pheej yig thiab lub neej ua haujlwm ntev (tsawg kawg qib B, X42)
Qhov Loj
API 5L kav dej muaj nyob rau hauv qhov ntev ntawm 2 mus rau 28 "(seaamless execution) thiab mus txog 80" nyob rau hauv welded execution (feem ntau, LSAW ie longitudinal submerged arc vuam).
API 5L thiab ASME B36.10 yeeb nkab qhov ntev thiab qhov hnyav yog, qhov tseeb, zoo ib yam.
Cov kab yeeb nkab los ntawm Vigor yog tsim thiab ua raws li API 5L tus qauv, thiab cov yeeb nkab kab uas tsim los ntawm Vigor tau raug sim ntawm cov neeg siv khoom qhov chaw thiab raug muab tso rau hauv ntau lawm. Cov neeg siv khoom tau muab cov lus pom zoo heev ntawm qhov zoo thiab kev pabcuam ntawm Vigor's kab yeeb nkab. Yog tias koj txaus siab rau Vigor lub drilling thiab ua tiav cov cuab yeej thiab cov cuab yeej txiav, thov tsis txhob yig tiv tauj peb kom tau txais cov kev pabcuam tshaj lij thiab cov khoom zoo tshaj plaws.
