Cov yeeb nkab steel raug cais los ntawm txoj kev tsim khoom

Cov kav hlau tuaj yeem muab faib ua ob pawg raws li kev tsim khoom: seamless steel kav thiab welded steel kav. Welded steel kav yog hu ua welded kav.
1. Seamless steel kav yuav muab faib ua kub dov seamless kav, txias-draw kav, precision steel kav, thermal expanded kav, txias spinning kav thiab extruded kav raws li cov txheej txheem ntau lawm.
Seamless steel kav yog ua los ntawm cov pa roj carbon zoo los yog hlau alloy, thiab muab faib ua kub dov thiab txias dov (kos).
2. Welded steel kav tau muab faib ua rau hauv cov kav dej welded, hluav taws xob welded (kuj welded) kav thiab tsis siv neeg arc welded kav 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 tau muab faib ua ob hom ntxiv vim lawv cov duab kawg. Rau puag ncig welded kav thiab tshwj xeeb-puab (square, ca, thiab lwm yam) welded kav.
Welded steel kav yog ua los ntawm steel daim hlau dov rau hauv tubular duab thiab welded nrog taub qab seams los yog kauv seams. Nyob rau hauv cov nqe lus ntawm kev tsim, lawv tau muab faib ua welded steel kav rau kev thauj mus los uas tsis tshua muaj siab, muab kauv seam fais welded steel kav, ncaj coil welded steel kav, hluav taws xob welded kav, thiab lwm yam. Seamless steel kav yuav siv tau nyob rau hauv cov kua pneumatic pipelines thiab gas pipelines nyob rau hauv ntau yam lag luam. Cov kav dej welded siv tau rau cov kav dej, cov kav dej, cov kav dej cua sov, cov kav dej hluav taws xob, thiab lwm yam.
