LSAW (Longitudinally Submerged Arc Welding) yog ib lub ntsiab lus kev lag luam sophisticated feem ntau siv los piav txog kev tsim khoom.
Cov txheej txheem no suav nrog kev siv ib qho nruab nrab rau cov phaj tuab ua cov khoom siv raw. Lub phaj steel yog ces molded los yog tsim rau hauv ib lub raj dawb paug los ntawm ib tug xovxwm los yog tshwj xeeb tsim tshuab. Cov yeeb nkab yog thaum kawg tsim los ntawm submerged arc vuam txheej txheem thiab nthuav dav rau qhov kawg sizing.
Cov khoom kawg ntawm LSAW steel yeeb nkab nthuav tawm ntau yam kev qhia tshwj xeeb, ua ke nrog lub vuam seam uas qhia txog cov yam ntxwv zoo ntawm cov tawv nqaij, plasticity, uniformity, thiab compactness. Qhov tshwj xeeb ntawm cov yeeb nkab steel no muaj ntau qhov zoo sib xws, nrog rau txoj kab uas hla loj, cov yeeb nkab phab ntsa tuab, qhov tshwj xeeb siab tsis kam, siab kub siab siab, thiab muaj zog corrosion kuj. Zuag qhia tag nrho, LSAW steel yeeb nkab yog cov khoom tsim nyog rau ntau yam kev siv thoob plaws ntau yam kev lag luam.
Thaum tsim cov kav dej ntev ntev thiab txhim khu kev qha rau kev thauj mus los ntawm cov roj thiab roj, feem ntau ntawm cov kav hlau uas xav tau yog cov kav dej loj, tuab-walled LSAW kav. Hauv kev ua raws li API cov qauv, LSAW cov kav dej tau tsim tshwj xeeb rau kev siv hauv Chav Kawm 1 thiab Chav Kawm 2, uas suav nrog thaj chaw nyuaj xws li thaj tsam alpine, seabeds, thiab cov nroog uas muaj neeg coob. Qhov no qhia txog qhov tseem ceeb ntawm kev siv cov yeeb nkab zoo LSAW hauv kev tsim cov raj xa dej kom ntseeg tau tias kev thauj mus los zoo thiab muaj txiaj ntsig zoo.
