Seamed steel kav yog hu ua welded kav, thiab muab faib mus rau hauv: ncaj seam welded kav thiab kauv welded kav raws li weld seam.
1. Kev faib tawm los ntawm txoj kev tsim khoom
(1) Seamless kav - cov kav dej kub dov, cov kav dej txias txias, cov kav dej txias txias, cov kav dej extruded, jacking kav (2) Welded kav (a) Raws li cov txheej txheem - arc welded kav, hluav taws xob kuj welded kav (siab zaus, tsawg zaus ), Gas welded yeeb nkab, rauv welded yeeb nkab (b) Raws li vuam seam - ncaj seam welded yeeb nkab, kauv welded yeeb nkab
2. cais raws li cov duab ntawm seem
(1) Tej yam yooj yim seem steel kav - round steel kav, square steel kav, oval steel kav, daim duab peb sab steel kav, hexagonal steel kav, pob zeb diamond steel kav, octagonal steel kav, semi-circular steel kav, thiab lwm yam
(2) Cov kav hlau uas muaj qhov nyuaj - tsis sib xws hexagonal steel kav, tsib-petal plum-puab steel kav, ob-convex steel kav, ob-concave steel kav, melon-shaped steel kav, conical steel kav, corrugated steel kav, rooj plaub. steel kav, thiab lwm yam.
3. Kev faib tawm los ntawm phab ntsa thickness- nyias-walled steel yeeb nkab, tuab-walled steel yeeb nkab
4. Kev faib tawm los ntawm kev siv- steel kav rau cov kav dej, cov kav hlau steel rau cov khoom siv thermal, steel kav rau kev lag luam machinery, steel kav rau roj av, geological drilling, thawv steel kav, steel kav rau tshuaj lom neeg kev lag luam, steel kav rau tshwj xeeb hom phiaj, thiab lwm yam.
