Taw qhia rauLSAW steel yeeb nkab
LSAW steel yeeb nkab, luv luv rau Longitudinal Submerged Arc Welded yeeb nkab, yog lub siab -lub zog welded steel yeeb nkab uas tsim los ntawm cov hlau hnyav los ntawm txoj kab ntev thiab submerged arc vuam. Nws yog dav siv nyob rau hauv cov roj thiab roj xa mus, dej pipelines, offshore structures, choj tsim, piling foundations, thiab loj -scale infrastructure tej yaam num.
Piv nrog rau lwm yam welded yeeb nkab, LSAW steel yeeb nkab yog tsim los rau loj diameters, tuab phab ntsa thickness, thiab siab - kev siv siab. Nws txoj kev tsim khoom tso cai rau kev tswj xyuas nruj thiab cov khoom siv kho tshuab ruaj khov, ua rau nws yog ib qho ntawm cov khoom siv hluav taws xob zoo tshaj plaws nyob rau hauv ntev - kis tau tus mob.
Nrog txoj kev loj hlob sai ntawm kev thauj mus los thoob ntiaj teb thiab kev tsim kho vaj tse, LSAW steel yeeb nkab tau dhau los ua cov kav dej tseem ceeb rau kev ua haujlwm siab - zog, siab - siab, thiab ntev - kev pabcuam - lub neej ua haujlwm.
Manufacturing txheej txheem ntawmLSAW steel yeeb nkab
LSAW steel yeeb nkab yog tsim los ntawm kub- dov steel daim hlau uas yog tsim rau hauv ib tug tubular zoo thiab welded longitudinally siv submerged arc vuam tshuab. Tag nrho cov txheej txheem ua raws li cov txheej txheem tswj kom zoo.
Kev xaiv raw khoom
LSAW kav yog tsim los ntawm siab- zoo carbon steel los yog qis- alloy structural steel daim hlau. Cov qib steel feem ntau suav nrog API 5L Gr.B, X42, X52, X60, X65, thiab X70, nrog rau ASTM A252, ASTM A671, thiab EN cov qauv.
Cov hlau phaj yuav tsum ua tau raws li cov tshuaj muaj pes tsawg leeg thiab cov cuab yeej cuab tam kom ntseeg tau tias weldability, toughness, thiab siab tsis kam.
Plate forming
Cov hlau phaj yog tsim rau hauv cov duab cylindrical siv JCO forming lossis UOE txoj kev siv tshuab.
JCO forming nias lub phaj ib kauj ruam mus rau hauv J, C, thiab O duab
UOE txoj kev nias lub phaj rau hauv U zoo, ces O zoo, ua raws li kev nthuav dav
Cov txheej txheem tsim no ua kom muaj qhov tseeb qhov tseeb thiab qhov sib npaug.
Submerged Arc Vuam
Tom qab tsim, lub longitudinal seam yog welded siv submerged arc vuam nrog muab tub lim hlau. Ob leeg sab hauv thiab sab nraud welding yog siv los lav tag nrho kev nkag mus thiab weld lub zog.
Cov txheej txheem vuam siv cov tshuab vuam tsis siv neeg uas muaj qhov ruaj khov tam sim no, qhov hluav taws xob, thiab kev mus ncig ceev kom ntseeg tau tias cov khoom siv vuam zoo.
Expansion thiab Sizing
Tom qab vuam, cov yeeb nkab yog mechanically nthuav dav los txhim kho roundness, txo qhov seem ntawm kev ntxhov siab, thiab txhim kho qhov ntev precision.
Tsis yog -Kev kuaj kev puas tsuaj
Txhua LSAW yeeb nkab tau dhau 100 feem pua ntawm kev kuaj ultrasonic, X- kev tshuaj xyuas kab hluav taws xob, thiab kev ntsuas hydrostatic siab ua ntej xa khoom.
