Ncaj seam yeeb nkabyog ib lub yeeb nkab steel uas nws qhov vuam seam yog parallel mus rau qhov ntev ntawm cov yeeb nkab. Nws yog feem ntau muab faib ua metric fais welded steel yeeb nkab, hluav taws xob welded nyias-walled yeeb nkab, transformer txias roj yeeb nkab, thiab lwm yam Longitudinal welded yeeb nkab ntau lawm txheej txheem yog yooj yim, siab ntau lawm efficiency, tsis tshua muaj nqi, ceev kev loj hlob. Siv rau kev xa cov kua dej uas tsis tshua muaj siab. Cov yeeb nkab steel yuav tsum tau nqa tawm dej siab, khoov thiab lwm yam kev sim, qhov zoo ntawm qhov chaw muaj qee yam yuav tsum tau ua. Feem ntau, qhov ntev ntawm tus me nyuam yog 4-10m, feem ntau yuav tsum tau kho ntev (los yog ob npaug ntev) xa, welded yeeb nkab specifications nyob rau hauv nominal txoj kab uas hla (mm los yog nti). Lub nominal txoj kab uas hla txawv ntawm qhov tseeb txoj kab uas hla. Raws li cov txheej txheem phab ntsa thickness, welded yeeb nkab tau muab faib ua cov yeeb nkab steel zoo tib yam thiab cov yeeb nkab tuab tuab.
