Raws li txoj kev tsim khoom, cov kav dej steel tuaj yeem muab faib ua seamless steel kav thiab welded steel kav. Welded steel kav yog hu ua welded kav rau luv luv.
1. Seamless steel raj yuav muab faib ua kub dov seamless raj, txias drawn tubes, precision steel hlab, kub expanded hlab, txias spun raj thiab extruded raj raws li ntau lawm txoj kev.
Seamless steel kav yog ua los ntawm high-zoo carbon steel los yog hlau alloy, uas yuav ua tau kub dov los yog txias dov.
2. Welded steel kav tau muab faib ua rau hauv cov kav dej rauv welded, hluav taws xob vuam (tsis kam vuam) cov kav dej thiab cov kav dej tsis siv neeg arc welded vim lawv cov txheej txheem vuam sib txawv. Lawv tau muab faib ua cov kav dej ncaj nraim thiab cov kav dej sib txuas vim lawv cov ntaub ntawv sib txawv. Lawv cov duab kawg kuj tau muab faib ua cov kav welded thiab tshwj xeeb-puab (square, ca, thiab lwm yam) welded kav.
Welded steel kav yog welded los ntawm dov steel daim hlau nrog pob tw los yog kauv seams. Nyob rau hauv cov nqe lus ntawm kev tsim cov txheej txheem, lawv kuj tau muab faib ua welded steel kav rau kev thauj mus los tsis tshua muaj siab kua, muab kauv hluav taws xob welded steel kav, ncaj dov welded steel kav, hluav taws xob welded kav, thiab lwm yam. Seamless steel kav yuav siv tau nyob rau hauv ntau yam industries, xws li kua thiab roj pipelines. Cov yeeb nkab vuam siv tau rau cov kav dej, cov yeeb nkab roj, cov yeeb nkab cua sov, cov yeeb nkab hluav taws xob, thiab lwm yam.
