SAW (Longitudinal Submerged Arc Welded) Cov kav dej sib txawv ntawm lwm hom welded kav siv hauv cov kav dej.Lawv feem ntau yog siv rau hauv cov roj thiab cov kav xa hluav taws xob,thiab kev siv cov txheej txheem xws li kev tsim cov choj thiab tunnels.
Hais txog cov qauv, cov kav dej LSAW ua raws li cov qauv tsim los ntawm American Petroleum Institute (API), Lub Koom Haum Thoob Ntiaj Teb rau Standardization (ISO), thiab Asmeskas
Society of Mechanical Engineers (ASME).Cov qauv no txhais cov kev qhia tshwj xeeb rau qhov ntev, tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab cov kev ntsuas rau cov kav dej LSAW.
LSAW pipesmuaj nyob rau hauv ntau qib xws li ASTM A671, ASTM A672, ASTM A525,TS EN 10210 BS, BS EN10219 THIABAPI 5L Gr.B.Qhov kev xaiv ntawm qib nyob ntawm daim ntawv thovcov kev xav tau xws li lub siab, qhov kub thiab txias, thiab hom kua dej thauj.
Kev siv cov kav dej LSAW muaj ntau haiv neeg, thiab lawv feem ntau yog siv rau hauv cov roj thiab cov roj xa hluav taws xob, cov kav dej, thiab kev siv cov txheej txheem xws li kev tsim cov choj thiab qhov.Cov kav dej no nyiam duatshaj lwm cov welded kav raws li lawv muaj qhov zoo ntawm qhov tseeb, siab zog, thiab kav ntev.LSAW cov kav dej tuaj yeem tsim muaj qhov loj thiab qhov ntev, ua rau lawv zoo tagnrho rau kev siv hauv cov kav xa mus ntev.
Hauv kev xaus, LSAW kav dej ua lub luag haujlwm tseem ceeb hauv kev xa cov roj thiab roj thiab kev siv cov txheej txheem.Lawv ua raws li cov qauv nruj, tuaj nyob rau hauv cov qib sib txawv, thiab ruaj khov thiab txhim khu kev qha.
