Kev Txhim Kho ntawm ERW steel Yeeb Nkab

High zaus ncaj ncaj seam welded yeeb nkab (ERW) yog kub dov npib phaj tsim los ntawm lub tshuab ua qauv, siv cov tawv nqaij ua kom sib luag thiab sib cuam tshuam ntawm qhov muaj zog tam sim no rau cov cua sov thiab yaj rau ntawm ntug ntawm lub raj dawb, thiab siab vuam raws kev ua ntawm nyem rau cov menyuam Kom tau ntau lawm. Qhov high-frequency kuj vuam txheej txheem tau siv rau kev tsim cov kav dej hlau txuas rau xyoo 1950. Nyob rau hauv kaum xyoo dhau los, nws cov cuab yeej tsim tawm tau dhau los ua ntau dua, thiab cov khoom zoo tau txuas ntxiv mus. Qhov thib ib yog tias cov khoom siv zoo ntawm cov khoom siv raw siv nyob rau hauv ERW ntau lawm tau zoo dua.

Qhov ob, kev tswj lub tshuab tsis siv neeg tau txais kev pom zoo hauv kev tsim cov khoom loj thiab nruab nrab-caliber ERW steel yeeb nkab ua vuam kev kho cua sov, thiab lub zog cov cua kub nkag thaum lub siab-vuam cov txheej txheem tau tswj tau zoo nrog lub khoos phis tawm ntawm lub tshuab them nyiaj, tiv thaiv vuam tshav kub input zog los ntawm qis qis Qhov tshwm sim txias vuam, vuam sib dhos thiab kub siab los ntawm kev kub nkag siab zog.
