Dab tsi yog qhov txawv ntawm seamless steel yeeb nkab thiab welded steel yeeb nkab?
Tam sim no, cov kav dej steel siv hauv peb lub neej niaj hnub tau muab faib ua ob hom: welded steel kav thiab seamless steel kav.Qhov sib txawv ntawm ob lub kav hlau no tuaj yeem txheeb xyuas los ntawm peb yam:
1. Nyob rau hauv tsos, qhov sib txawv ntawm seamless steel yeeb nkab thiab welded steel yeeb nkab yog hais tias lub puab phab ntsa ntawm cov welded yeeb nkab muaj vuam tav, thaum lub seamless steel yeeb nkab tsis.
2. Lub siab ntawm seamless yeeb nkab yog siab, thiab welded yeeb nkab feem ntau yog li 10MPa.Tam sim no lub welded yeeb nkab yog seamless.
3. Seamless steel yeeb nkab yog tsim nyob rau hauv ib lub sij hawm thaum lub sij hawm dov txheej txheem.Welded steel kav yuav tsum tau dov thiab welded, thiab kauv vuam thiab ncaj welding feem ntau yog siv.Seamless kav dej ua tau zoo dua thiab tau kawg raug nqi ntau dua.
