1.GENERAL INTRODUCTION ntawm LSAW PIPE
Longitudinally Submerged Arc Vuam yeeb nkab (lub npe hu ua LSAW yeeb nkab). Lub Longitudinally Submerged Arc Vuam (LSAW) yog tsim los ntawm kev siv ib lub phaj raws li cov khoom siv raw, nias (rolling) steel phaj rau hauv cov yeeb nkab tsis muaj pwm los yog lub tshuab moulding, thiab siv ob sab submerged arc vuam thiab nthuav dav. txoj kab uas hla. Cov khoom tiav lawm muaj ntau yam specifications, thiab cov weld muaj zoo toughness, plasticity, uniformity thiab compactness, thiab muaj qhov zoo ntawm cov yeeb nkab loj txoj kab uas hla, tuab yeeb nkab phab ntsa, siab kub tsis kam, tsis kub tsis kam thiab corrosion kuj.
Thaum tsim cov high-strength, high-toughness, high-zoo nyob deb deb cov roj thiab roj pipelines, feem ntau ntawm cov yuav tsum tau steel kav yog loj-inch tuab-walled ncaj seam submerged arc welded kav. Raws li API tus qauv, nyob rau hauv cov roj thiab cov kav dej loj, qhov ncaj seam submerged arc welded yeeb nkab yog tib hom yeeb nkab uas tau xaiv thaum dhau los ntawm Class I thiab Class 2 thaj chaw xws li thaj chaw siab siab, seabeds, thiab hauv nroog cov chaw muaj neeg coob.
2.HOM LSAW PIPE
Raws li kev sib txawv molding, nws tuaj yeem muab faib ua:
UOE welded yeeb nkab:Tom qab ua ntej khoov ntawm ib lub phaj steel, U-forming, O-forming, internal welding, sab nraud vuam, mechanical txias expansion thiab lwm yam txheej txheem;
JCOE welded yeeb nkab:nws yog raws li tus txheej txheem ntawm "JCOE" pre-welding, sib sau, txias-expanding tom qab vuam;
HME welded yeeb nkab:Nws yog tsim los ntawm "CCO" los ntawm mandrel dov txoj kev, thiab cov txheej txheem ntawm txias expansion tom qab vuam.
3.Technical PARAMETERS LSAW PIPE
Lub ntsiab technical parameters ntawm LSAW yog raws li nram no:
Phab ntsa thickness:6.4-23.8mm (0.252-0.94in) hauv X80 steel qib thiab 6.4-26.4mm (0.252-1.04in) hauv X70 steel qib. Cov phab ntsa tuab tuaj yeem nce mus rau qhov sib txawv raws li cov khoom siv qis dua.
Khoom qauv:ISO3183-3, API Spec 5L, GB9711, thiab lwm yam.
Ncaj seam submerged arc welded steel yeeb nkab txoj kab uas hla mus txog Φ406.4-Φ1422.4mm
Cov yeeb nkab steel tuaj yeem ncav cuag 12.2m ntev thiab phab ntsa tuab yog 6.4-26.4mm ntawm qib × 70 steel.
4.MAIN FEATHERS NTAWMLSAWPIPE:
1) Cov yeeb nkab steel muaj qhov ntev vuam, thiab sab hauv thiab sab nraud yog welded los ntawm submerged arc vuam.
2) Tom qab kev kho txhua yam kev nthuav dav, qhov kev ntxhov siab sab hauv ntawm cov yeeb nkab steel yog me me thiab sib npaug sib npaug, uas tuaj yeem tiv thaiv kev ntxhov siab corrosion tawg, siab qhov tseeb, thiab yooj yim rau kev siv vuam ntawm qhov chaw.
3) Siv cov txheej txheem ua ntej vuam tom qab vuam, cov txheej txheem vuam yog ruaj khov thiab cov vuam zoo yog siab.
4) Welds yog ib qho yooj yim kom ua tiav qhov kev sim tsis muaj kev puas tsuaj thaum lub sij hawm tsim khoom thiab kev sim tsis muaj kev puas tsuaj hauv thaj chaw thaum siv.
5) Cov khoom lag luam tshwj xeeb yog qhov loj, uas tuaj yeem tsim cov kab me me, phab ntsa loj thiab tuaj yeem tsim cov kab loj loj thiab cov phab ntsa loj tuab steel yeeb nkab.
