Ncaj seam ncaj steel yeeb nkab tsis yog tsuas yog hom hlau yeeb nkab, tab sis ntau yam ntawm cov yeeb nkab welded. Nws yog ua los ntawm cov hlua steel thiab ua ntawm ncaj seam high-zaus vuam cov khoom siv. Qhov no zoo ntawm cov yeeb nkab steel muaj peev xwm tiag tiag hu ua kev ncaj ncaj.
Ntawm lawv, raws li kev siv sib txawv thiab cov txheej txheem tsim tawm tom qab, nws tuaj yeem raug faib ua cov kav dej txuas, cov kav dej ua kua, xaim xaim xaim, txhawb cov kav dej, cov kav dej muaj khoom, thiab lwm yam. Tom qab lub vuam tiav tas, ua tiav dej vapor xa mus kuaj dua. Yog li ntawd, tus nqi ntawm cov kua dej uas tsis tshua muaj siab siab siab feem ntau siab dua li cov dog dig uas txuas ntev dua. Xws li: welded steel yeeb nkab ua kua dej 1 nti (DN25) (33.5 * 3.25) welded steel yeeb nkab: tseem hu ua cov yeeb nkab welded. Nws yog welded los ntawm nkhaus steel phaj lossis steel sawb. Raws li daim ntawv weld, nws muab faib ua cov ncaj seam welded yeeb nkab thiab kauv welded yeeb nkab. Raws li lub hom phiaj, nws tuaj yeem muab faib ua cov yeeb nkab uas tsis muaj dab tsi txuas, galvanized welded yeeb nkab, oxygen tshuab lub raj xa hluav taws xob, kab casing, sib sib zog nqus zoo yeeb nkab, tsheb yeeb nkab, transformer yeeb nkab, welded nyias-walled yeeb nkab, thiab welded tshwj xeeb zoo li tus yeeb nkab thiab muab kauv welded yeeb nkab.
