Muab faib
Raws li cov txheej txheem ntau lawm, cov kav dej steel tuaj yeem muab faib ua ob pawg: seamless steel kav thiab welded steel kav.welded steel kav yog hu ua welded kav rau luv luv.
Seamless steel kav yuav muab faib ua kub dov seamless kav, txias drawn kav, precision steel kav, kub expanded kav, txias spun kav, thiab extruded kav raws li ntau lawm txoj kev.
Seamless steel kav yog ua los ntawm cov pa roj carbon zoo los yog hlau alloy, thiab tuaj yeem ua tau kub dov los yog txias dov (kos).
Welded steel kav tau muab faib ua rau cov kav hlau txuas hluav taws xob, hluav taws xob vuam (ua haujlwm vuam) cov kav dej, thiab cov kav dej tsis siv neeg arc welded vim lawv cov txheej txheem vuam sib txawv.Vim lawv cov ntaub ntawv sib txawv, lawv tau muab faib rau hauv cov kav dej ncaj nraim thiab cov kav welded kav.Vim lawv cov duab kawg, lawv tau muab faib ntxiv rau hauv cov kav welded thiab tshwj xeeb-puab (square, ca, thiab lwm yam) welded kav.
Welded steel kav yog tsim los ntawm welding steel daim hlau dov rau hauv tubular duab nrog taub qab los yog kauv seams.Nyob rau hauv cov nqe lus ntawm kev tsim cov txheej txheem, lawv tau muab faib ua welded steel kav rau kev thauj mus los tsis tshua muaj siab kua, kauv welded steel kav, ncaj dov steel kav, thiab hluav taws xob welded kav.Seamless steel kav yuav siv tau nyob rau hauv ntau yam kev lag luam xws li kua roj pipelines thiab gas pipelines.Cov kav dej welded tuaj yeem siv rau cov kav dej, cov kav dej, cov kav dej cua sov, cov kav dej hluav taws xob, thiab lwm yam.
