Qhov kev ua tau zoo ntawm txoj hlua ncaj nraim submerged arc welded yeeb nkab yog zoo dua li ntawm kauv submerged arc welded yeeb nkab. Cov ntsiab lus hauv qab no piav qhia vim li cas.
Kauv submerged arc welded kav dej muaj kev ntxhov siab ntau dua li cov kav dej ncaj nraim submerged arc welded kav. Longitudinal submerged arc welded kav undergo uniform txoj kab uas hla expansion.
Qhov kev nyuaj siab concentration tshwm sim nyob rau hauv weld seam ntawm kauv submerged arc welded yeeb nkab yog loj. Lub tshav kub cuam tshuam cheeb tsam ntawm kauv submerged arc welded yeeb nkab yog loj tshaj qhov ncaj seam submerged arc welded yeeb nkab. Lub tshav kub cuam tshuam rau cheeb tsam yog suav tias yog qhov tsis muaj zog uas yuav tshwm sim.
Qhov tseeb geometric ntawm LSAW yeeb nkab yog zoo dua li ntawm SSAW yeeb nkab, uas yog qhov tseem ceeb rau kev yooj yim ntawm installation.
LSAW yeeb nkab muaj kwv yees li 60% tsawg dua cov kab ntau dua li SSAW yeeb nkab.
Siv cov ntawv hlau, qhov zoo ntawm cov kav dej hauv qhov ntev ntawm cov arc welded tuaj yeem raug kuaj los ntawm cov txheej txheem kuaj tsis muaj kev puas tsuaj. Kauv submerged arc welded kav uas siv cov kub dov coils yuav tsum tau kuaj xyuas siv txoj kev puas tsuaj xws li X-rays.
Longitudinal submerged arc welded kav siv cov txheej txheem tom qab tsim vuam uas tso cai rau ntau yam kev tshuaj xyuas. Kauv submerged arc welded kav yog tsim thiab welded ib txhij yam tsis muaj kev tshuaj xyuas ua ntej.
LSAW yeeb nkab txoj kab uas hla yog feem ntau los ntawm 16inch txog 60inch (406mm txog 1500mm). Lawv muaj kev ua tau zoo ntawm kev kub siab ua haujlwm, thiab qis-kub corrosion kuj.
