Khoom Description
Seamless yeeb nkab yog lub hollow tubular hlau tsis muaj vuam seams, uas yog tsim los ntawm perforated kub dov, txias kos duab los yog txias dov txheej txheem. Nws muaj cov yam ntxwv ntawm cov qauv sib xws, siab zog thiab zoo sealing. Nws qhov chaw feem ntau yog cov xim qub ntawm cov hlau (nyiaj grey), thiab tuaj yeem ua rau galvanized, pleev xim rau, plated thiab lwm yam tshuaj tiv thaiv- kho corrosion raws li kev xav tau. Raws li cov txheej txheem ntau lawm, nws tau muab faib ua:
Kub- dov seamless yeeb nkab: tuab phab ntsa tuab, loj txheej kab uas hla, haum rau kev kub siab thiab siab zog scenes;
Cold dov / txias drawn seamless yeeb nkab: siab precision, du nto, niaj hnub phab ntsa thickness, feem ntau yog siv rau precision machinery los yog dej thauj.
Raws li cov khoom, nws muab faib ua:
Carbon steel seamless yeeb nkab (xws li Q235, 20# steel): tus nqi qis thiab daim ntawv thov dav;
Alloy steel seamless yeeb nkab (xws li 15CrMo, 42CrMo): kub kub, siab siab thiab corrosion kuj;
Stainless hlau seamless yeeb nkab (xws li 304, 316L): zoo heev corrosion kuj, haum rau zaub mov, kho mob, tshuaj thiab lwm yam teb.
