Welded steel kav yog tsim los ntawm curling steel daim hlau los yog steel strips thiab ces welding lawv ua ke. (cov txheej txheem muaj xws li ERW\\SAW\\LSAW\\SSAW).
Seamless steel kav yog tsim los ntawm kev tho cov khoom puag ncig steel billets, ua raws li kub dov, txias dov los yog txias txias, tsis muaj weld seams thoob plaws hauv cov yeeb nkab (cov txheej txheem suav nrog kub dov, txias dov, extrusion, thiab lwm yam).
Feem ntau, qhov siab tshaj plaws kev nyab xeeb kev khiav hauj lwm siab rau welded kav yog nyob rau hauv 20 kg, uas yog lawv cov kev nyab xeeb daim ntawv thov ntau yam. Lawv feem ntau yog siv los thauj cov dej tsawg- xws li dej, roj, thiab cua compressed.
Cov kav dej seamless tuaj yeem tiv taus ultra-siab siab, thiab lawv cov phab ntsa thickness yuav nce ntxiv, uas yuav tsum tau tsim raws li cov kev xav tau tshwj xeeb. Lawv feem ntau yog siv rau hauv siab - kub thiab siab - cov cuab yeej siv siab xws li siab - cov kav dej thiab cov kav dej boiler.
Muaj ib hom kua yeeb nkab uas yog qhov ua tiav ERW yeeb nkab. Cov txheej txheem kev kho mob suav nrog kev npaj lossis sib tsoo tawm ntawm qhov qub weld seam nrog cov cuab yeej tshwj xeeb, lossis kub dov cov yeeb nkab welded. Cov kab yuav nyob twj ywm ntawm cov kav dej uas tau npaj los yog hauv av; Qee cov kab mob yog qhov pom tseeb heev, thiab lawv tuaj yeem ua qhov txawv dua tom qab xeb tshem tawm nrog cov cuab yeej. Kev soj ntsuam kom zoo yuav qhia tau tias xeb ntawm 20 # steel thiab Q235 steel sib txawv vim lawv cov khoom sib txawv. Cov neeg tsim khoom ntawm cov kav dej zoo li no, tawm ntawm kev ntshai ntawm kev lav phib xaub, tsuas yog sau lawv li "cov kav dej" ntawm daim ntawv pov thawj zoo es tsis txhob "cov kav dej seamless rau kev thauj mus los".
