High Precision Seamless Bright Tube
Lub tsheb, tshuab qhov chaw, thiab lwm yam. muaj cov kev xav tau siab ntawm qhov precision thiab tiav ntawm cov kav dej steel. Cov neeg siv cov yeeb nkab steel tsis yog tsuas yog cov neeg siv uas muaj qhov yuav tsum tau ua kom raug thiab du. Vim tias qhov tseeb ntawm cov kav dej zoo meej yog qhov siab thiab kev ua siab ntev tuaj yeem tswj tau ntawm 2--8 xov hlau, ntau cov neeg siv tshuab yuav txuag zog, khoom siv, thiab lub sijhawm poob. Seamless steel raj los yog round steel yog maj mam hloov mus rau hauv precision ci raj.
Ib:Paub seamless ci raj sab nraud txoj kab uas hla, specification, phab ntsa thickness yuav tsum tau dais lub siab xam txoj kev (lub tensile zog ntawm txawv steel yeeb nkab cov ntaub ntawv yog txawv)
Siab = (phab ntsa thickness * 2 * steel yeeb nkab khoom tensile lub zog) / (sab nraud txoj kab uas hla * coefficient)
Ob: Paub seamless yeeb nkab sab nraud txoj kab uas hla ntawm seamless steel yeeb nkab thiab xam txoj kev ntawm phab ntsa thickness nyob rau hauv siab:
Phab ntsa thickness = (siab * sab nraud txoj kab uas hla * coefficient) / (2 * steel yeeb nkab khoom tensile zog)
Peb: Cov txheej txheem ntawm kev nthuav qhia lub siab coefficient ntawm seamless ci raj:
Hlau yeeb nkab siab P <7Mpa coefficient S = 8
7
Hlau yeeb nkab siab P> 17.5 coefficient S = 4
