ASTM A234 Longitudinal Welded Yeeb Nkab
Qhia:
Nyob rau hauv lub ntiaj teb no ntawm cov yeeb nkab steel, ib lo lus nquag tuaj ntau zaus: longitudinally welded yeeb nkab.Cov kav dej no ua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam thiab ua haujlwm rau ntau lub hom phiaj.
Longitudinal welded yeeb nkab, tseem hu ua ncaj seam welded yeeb nkab, yog cov yeeb nkab steel ua los ntawm kub dov los yog txias dov steel phaj lossis steel strip coil.Lawv lub npe yog los ntawm cov txheej txheem vuam, uas tshwm sim hauv txoj kab ncaj nraim raws qhov ntev ntawm cov yeeb nkab.Txoj hauv kev no ua kom muaj qhov zoo sib xws ntawm cov weld zoo thiab cov pob qij txha nruj, tiv thaiv kom tsis txhob tawg thiab txhim kho tag nrho cov qauv kev ncaj ncees.

Longitudinal welded yeeb nkab:
Ntawm qhov tod tes,ncaj welded kavyog tsim los siv ntau yam kev siv vuam xws li arc vuam lossis tsis kam vuam.Cov kav dej no feem ntau yog ua los ntawm seamless los yog welded raj blanks, uas yog ces tsim rau hauv cov duab xav tau.Longitudinal Welded Yeeb Nkab muaj qhov tshwj xeeb lub zog thiab ua haujlwm ntev, ua rau nws zoo tagnrho rau cov ntawv thov kev lag luam uas muaj kev kub ntxhov lossis hnyav hnyav.
Longitudinal welded kav tau txais cov txheej txheem vuam zoo los xyuas kom meej cov phab ntsa tuab thoob plaws hauv cov yeeb nkab nrog qhov tsis xws luag.Qhov no ua rau lawv xaiv zoo heev rau kev siv cov qauv xws li kev tsim kho, scaffolding thiab piling.
Ncaj welded kav, ntawm qhov tod tes, tuaj ntau yam duab thiab ntau thiab tsawg.Lawv cov txheej txheem tsim khoom tso cai rau kev hloov kho, ua rau lawv haum rau cov ntawv thov uas xav tau qhov ntev lossis cov qauv tsim.Tsis tas li ntawd, longitudinally welded kav yog dav siv nyob rau hauv kev lag luam xws li roj thiab roj, tsheb, thiab aerospace vim lawv superior zog thiab kev nyuaj siab.
