Dab tsi txiav txim siab qhov zoo ntawm ERW kav dej?
Qhov zoo ntawm ERW yeeb nkab hauv kev tsim khoom txiav txim siab nws qhov zoo ntawm kev siv, thiab qhov kub stamping ntawm qhov khoob txawv raws li cov khoom siv. Kev khiav hauj lwm kub ntawm thermal expansion welded yeeb nkab yog li 1200 degree. Thaum cov ntsiab lus carbon thiab lwm yam alloying ntsiab lus ntau dua, qhov kub thiab txias me ntsis.
Cov txheej txheem vuam ntawm ERW yeeb nkab txawv ntawm cov yeeb nkab zoo tib yam. Lub weld seam yog yaj los ntawm cov khoom siv hauv lub cev ntawm lub cev steel, thiab nws cov khoom siv dag zog zoo dua li cov kav dej zoo tib yam. Smooth tsos, siab precision thiab tsis tshua muaj nqi. Feem ntau siv rau hauv cov kav dej txias txias, cov kav dej siab, thiab cov kav dej nag hauv kev cob qhia, cov tsev siab, thiab lwm yam.
Ordinary welded kav feem ntau yog siv los thauj cov kua uas tsis tshua muaj siab. Cov khoom siv yog Q195A, Q215A, Q235A steel, thiab lwm yam qis carbon steels kuj siv tau. Cov yeeb nkab steel yuav tsum muaj cov lus xws li siab, khoov, thiab flattening. Raws li cov kev cai ntawm phab ntsa thickness, lawv tau muab faib ua cov kav hlau zoo tib yam thiab cov kav hlau tuab. Raws li qhov kawg taw tes, nws tuaj yeem muab faib ua cov yeeb nkab threaded thiab unthreaded yeeb nkab.
