JIS G3454 Cov Yeeb Nkab Hlau Rau Lub Siab
JIS G3454 Cov kav dej steel siv rau cov kav dej siab siv nyob rau hauv qab no txog 350 degree. Txawm li cas los xij, qhov no tsis siv rau cov roj hlau steel rau siab rau high-} siab piping. Cov qauv no siv rau cov kav dej nrog cov taub sab nraud ntawm 10,5 mm (nominal theep 64 mm) rau 650A lossis 26B). Tsis tas li ntawd, cov khoom ntawm cov tshwj xeeb tshwj xeeb uas tus neeg txiav txim tshwj xeeb ua ntej los ntawm kev pom zoo nrog cov chaw tsim khoom yog cov qauv hauv Annex Ja.

Txoj Kev Raug:Seamless, hluav taws xob tiv taus vuam, lossis taub qab vuam yuav siv tau. Cov yeeb nkab yuav yog li - Nrum} Nrum lossis txias - Ua haujlwm, thiab yuav tsum tau ua haujlwm sov yog tias tsim nyog.
Cov kev xav tau:Cov yeeb nkab yuav tsum yog qhov tseem ceeb ncaj, nrog ob qho kawg txiav mus rau cov yeeb nkab axis. Sab hauv thiab sab nraud yuav tsum tau du thiab dawb ntawm qhov tsis xws luag uas tuaj yeem ua tau zoo.
