Ua ntej, kev faib cov kav dej
1. Muab faib los ntawm txoj kev tsim khoom
(1) Seamless yeeb nkab - kub dov yeeb nkab, txias dov yeeb nkab, txias drawn yeeb nkab, extruded yeeb nkab, yeeb nkab jacking
(2) welded yeeb nkab
(a) Raws li cov txheej txheem - arc welded yeeb nkab, hluav taws xob kuj welded yeeb nkab (siab zaus, tsawg zaus), roj welded yeeb nkab, rauv welded yeeb nkab
(b) Raws li lub vuam seam - ncaj seam welded yeeb nkab, kauv welded yeeb nkab
2, raws li cov duab ntawm seem
(1) Tej yam yooj yim seem steel yeeb nkab - puag ncig steel yeeb nkab, square steel yeeb nkab, elliptical steel yeeb nkab, daim duab peb sab steel yeeb nkab, hexagonal steel yeeb nkab, pob zeb diamond steel yeeb nkab, octagonal steel yeeb nkab, semicircular steel voj voog, lwm yam
(2) Complex seem steel yeeb nkab - tsis sib npaug hexagonal steel yeeb nkab, tsib-petal plum-puab steel yeeb nkab, ob chav convex steel yeeb nkab, ob chav concave steel yeeb nkab, melon-shaped steel yeeb nkab, conical steel yeeb nkab, corrugated steel yeeb nkab, rooj plaub steel yeeb nkab, lwm tus
3, raws li phab ntsa thickness faib - nyias-walled steel yeeb nkab, tuab-walled steel yeeb nkab
4. Kev faib tawm los ntawm kev siv - steel yeeb nkab rau cov kav dej, cov yeeb nkab steel rau cov khoom siv thermal, steel yeeb nkab rau kev lag luam machinery, roj av, geological drilling steel yeeb nkab, thawv steel yeeb nkab, chemical kev lag luam steel yeeb nkab, tshwj xeeb lub hom phiaj steel yeeb nkab, lwm yam
