Sab nraud txoj kab uas hla ntawm kub dov seamless yeeb nkab yog feem ntau ntau dua 32 hli, thiab phab ntsa thickness yog 2.5-200 hli. Sab nraud txoj kab uas hla ntawm txias-dov seamless steel yeeb nkab tuaj yeem ncav cuag 6 hli, thiab phab ntsa tuab tuaj yeem ncav cuag 0.25 hli. Sab nraud txoj kab uas hla ntawm nyias-walled yeeb nkab tuaj yeem ncav cuag 5mm thiab phab ntsa thickness tsawg dua 0.25mm.

Feem ntau siv seamless steel yeeb nkab yog ua los ntawm 10, 20, 30, 35, 45 thiab lwm yam zoo carbon bonded steel 16Mn, 5MnV thiab lwm yam uas tsis muaj alloy structural steel los yog 40Cr, 30CrMnSi, 45Mn2, 40MnB thiab lwm yam steel bonded kub dov los yog txias. rolled.10, 20 thiab lwm yam tsawg carbon steel manufacturing seamless yeeb nkab yog tsuas yog siv rau cov kua pipeline.45, 40Cr thiab lwm yam nruab nrab carbon steel ua los ntawm seamless yeeb nkab los tsim mechanical qhov chaw, xws li tsheb, tsheb laij teb stressed qhov chaw.Qhov dav siv seamless steel yeeb nkab los xyuas kom meej lub zog thiab flattening test.Kub dov steel kav yog xa nyob rau hauv kub dov los yog kub kho mob.Cold rolled xa yog tshav kub - kho.
