Nyob rau hauv cov nqe lus ntawm ntau lawm txoj kev, nws kuj yuav muab faib mus rau hauv welded steel kav rau kev thauj mus los tsis tshua muaj siab kua, welded steel kav, kauv welded steel kav, thiab lwm yam. Seamless steel yeeb nkab yuav siv tau rau ntau yam kua thiab roj pipelines. Cov kav dej welded tuaj yeem siv rau cov kav dej, cov kav dej, cov kav dej cua sov, thiab lwm yam.
Cov kav hlau tuaj yeem muab faib ua ob pawg raws li kev tsim khoom: seamless steel kav thiab welded steel kav.
1. Seamless steel yeeb nkab yuav muab faib ua kub dov seamless yeeb nkab, txias drawn yeeb nkab, zoo steel yeeb nkab, kub expanded yeeb nkab, txias spinning yeeb nkab thiab kneading yeeb nkab raws li cov txheej txheem ntau lawm. Seamless steel yeeb nkab yog ua los ntawm high-quality carbon steel los yog alloy steel, uas yuav muab faib ua kub dov thiab txias dov (kos duab).
2. Welded steel yeeb nkab yog muab faib ua rau lub cub tawg welded yeeb nkab, hluav taws xob vuam (tsis kam vuam) yeeb nkab thiab active arc welded yeeb nkab vim nws cov txheej txheem vuam sib txawv. Vim nws txoj kev vuam sib txawv, nws tau muab faib ua cov yeeb nkab ncaj welded thiab kauv welded yeeb nkab. Vim nws qhov kawg zoo, nws muab faib ua puag ncig welded yeeb nkab thiab tshwj xeeb-puab (square, ca, thiab lwm yam) welded yeeb nkab. Welded steel kav yog ua los ntawm dov steel phaj welded nrog taub qab los yog kauv seams,
Raws li kev faib tawm ntawm cov khoom siv raw, cov kav hlau steel tuaj yeem muab faib ua cov kav dej carbon, cov kav hlau alloy, cov kav hlau tsis muaj steel, thiab lwm yam. Cov kav dej carbon kuj tseem tuaj yeem muab faib ua cov kav dej carbon steel dav dav thiab cov kav dej zoo carbon zoo. Cov kav hlau alloy tseem tuaj yeem muab faib ua cov kav hlau tsis tshua muaj hlau, cov kav hlau alloy, cov kav dej siab thiab cov kav dej muaj zog. Cov kabmob yeeb nkab, kub-resistant thiab acid-resistant stainless hlau yeeb nkab, zoo alloy (xws li kovar alloy) yeeb nkab thiab high-temperature alloy yeeb nkab, thiab lwm yam.
Raws li txoj kev sib txuas, cov yeeb nkab steel tuaj yeem muab faib ua ob hom raws li txoj kev sib txuas ntawm cov yeeb nkab kawg: threading yeeb nkab thiab cov yeeb nkab du. Threading yeeb nkab tau muab faib ua cov yeeb nkab dav dav thiab cov yeeb nkab tuab tuab ntawm cov yeeb nkab kawg. Thickened threading yeeb nkab kuj tseem tuaj yeem muab faib ua cov thickening sab nraud (nrog rau cov xov sab nraud), nrog cov xov sab hauv (nrog xov sab hauv) thiab sab nraud thickening (nrog xov sab hauv). Threading yeeb nkab kuj tuaj yeem muab faib ua cov cylindrical lossis conical xov thiab xov tshwj xeeb raws li xov hom.
