Ncaj seam welded steel kav muaj xws li ob-sided submerged arc welded ncaj seam welded steel kav thiab high-frequency kuj welding. Cov lus Askiv luv yog lsaw. Cov lus Askiv luv ntawm high-frequency resistance welding yog erw. Submerged arc welded ncaj seam steel kav tau muab faib ua UOE raws li lawv txoj kev sib txawv. , RBE, JCOE steel kav, thiab lwm yam. Cov ntaub ntawv ntawm ncaj seam welded steel kav mas muaj xws li pipeline steel series xws li Q195, Q215, Q345 thiab x42. Ncaj seam welded steel kav tau muab faib ua ob hom: cov kav hlau zoo tib yam thiab cov kav hlau tuab raws li cov phab ntsa tuab. Cov kav hlau hlau tau muab faib ua ob hom: threaded thiab tsis-threaded raws li cov duab ntawm cov yeeb nkab kawg. Qhov ntev ntawm qhov ncaj seam welded steel kav feem ntau muab faib ua qhov ntev thiab qhov sib txawv. Qhov no feem ntau yog raws li cov neeg siv khoom xav tau. Qhov ntev yog feem ntau 6-14 meters. Loj txoj kab uas hla ncaj seam welded steel kav tej zaum yuav xav tau ob daim hlau rau dov, uas kuj tsim ib ob welds.
Cov specifications ntawm ncaj seam welded steel kav yog qhia los ntawm nominal txoj kab uas hla thiab phab ntsa thickness. Raws li phab ntsa tuab, lawv tuaj yeem muab faib ua ob hom: nyias-walled ncaj seam kav thiab tuab-walled ncaj seam kav. Raws li cov duab, nws tuaj yeem muab faib ua puag ncig, square lossis tshwj xeeb-shaped leeg. Cov qauv siv tseem ceeb yog GB/T3091-2008 thiab GB/T9711-2008.
Kev Siv: Cov kav hlau hlau yog siv rau ntau yam khoom siv, qhov chaw thiab cov kav dej xa hluav taws xob nrog rau hluav taws xob welded steel kav rau lwm lub hom phiaj.
