Lub ERW steel raj kuj tau nkag siab tias txoj hlua ncaj nraim. Raws li cov phab ntsa ntom ntom, cov yeeb nkab sib txuas tau muab faib ua ntau hom thiab cov phab ntsa tuab. Peb tuaj yeem muab cov khoom lag luam nrog cov phab ntsa customized raws li cov neeg siv khoom tshwj xeeb nrog qhov sib txawv thickness tsis ntau tshaj 0.25 hli.
Nrog rau qhov ntau thiab tsawg ntawm 1/2-nti thiab 24-nti, peb ERW steel tubes dhau los ntawm kev sim nruj thiab kev soj ntsuam, txhawm rau lav qhov zoo ntawm vuam, precision ntawm sab nraud txoj kab uas hla, ovalization, txiav compressions, zoo ntawm raj kawg, kam rau ua. phab ntsa tuab, thiab ntim khoom zoo yog tag nrho raws li API5L, ASTMA53, GB / T9711.1, lossis GB / T3091 yuav tsum.
