1. Txheem txoj kab uas hla ntawm seamless yeeb nkab
Txoj kab uas hla ntawm cov kav dej seamless feem ntau ntsuas hauv millimeters, thiab nws cov qauv qhov ntev tau teev tseg hauv ISO 3160 tus qauv. Raws li tus qauv no, tus qauv diameters ntawm cov kav dej seamless tau muab faib ua cov hauv qab no:
1. 1/8 nti (3.18 mm) ~ 6 ntiv tes (152.4 mm), qhov no yog tus qauv txoj kab uas hla ntawm seamless kav.
2. 1/8 nti (3.18 mm) mus rau 2 ntiv tes (50.8 mm), uas yog cov kab ntau ntau ntawm seamless kav.
3. Seamless yeeb nkab diameters nyob rau hauv qhov ntau ntawm 2 ntiv tes (50.8 mm) mus rau 6 ntiv tes (152.4 mm) feem ntau yog siv rau lub hom phiaj tshwj xeeb.
2. Phab ntsa thickness ntawm seamless yeeb nkab
Phab ntsa thickness ntawm seamless yeeb nkab yog hais txog lub thickness ntawm cov yeeb nkab phab ntsa, thiab nws cov qauv qhov ntev tau teev nyob rau hauv raws li ISO 3160 tus qauv. Raws li tus qauv no, phab ntsa thickness ntawm seamless kav feem ntau muab faib ua cov nram qab no series:
1. 1/8 nti (3.18 mm) ~ 1/2 nti (12.7 mm), uas yog cov phab ntsa nyias nyias ntawm seamless kav.
2. 1/2 nti (12.7 mm) mus rau 3 nti (76.2 mm), uas yog cov phab ntsa thickness ntau ntawm seamless kav.
3. Seamless yeeb nkab phab ntsa thicknesses nyob rau hauv no ntau yam ntawm 3 nti (76.2 hli) mus rau 6 nti (152.4 hli) feem ntau yog siv rau tshwj xeeb hom phiaj.
3. Cov khoom siv seamless yeeb nkab
Seamless kav yuav ua tau los ntawm ntau yam ntaub ntawv hlau, xws li carbon steel, alloy steel, stainless hlau, thiab lwm yam. Seamless kav ntawm cov ntaub ntawv sib txawv muaj cov yam ntxwv sib txawv thiab haum rau txawv engineering teb. Piv txwv li, stainless hlau seamless kav muaj zoo heev corrosion kuj thiab haum rau corrosive ib puag ncig xws li tshuaj lom neeg kev lag luam thiab zaub mov; carbon steel thiab alloy steel seamless kav dej muaj lub zog siab thiab hnav tsis kam thiab tsim nyog rau kev lag luam hnyav, kev tsim khoom thiab lwm yam haujlwm.
