{{0 {}}} ** Cov txiaj ntsig ntawm ERW li cas? **
* ** Tus nqi pheej yig dua: ** tseem pheej yig dua li cov kav dej uas ua tau los ntawm cov kav dej uas muaj txiaj ntsig, kev ceev ceev ntau lawm los ntawm coil .
* ** Tus nqi ntau lawm: ** cov txheej txheem sib txuas ntxiv tso cai rau cov khoom loj sai sai {}}
* ** Kev saib xyuas zoo nyob ib ce: ** Kev tswj lub taub dhuav dhau lub taub, phab ntsa thickness, thiab roundness .
* ** Muaj nyob rau hauv diameters loj heev: ** Ntau dua muaj nyob rau hauv diameters loj (piv rau seamless) ntawm cov nqi tsim nyog {}}
* ** WELD Weld muaj zog (niaj hnub zoo nkauj): ** Adnanced high-furnency vuam thiab tshuaj xyuas kom ntseeg tau Weld Zog ....
* ** Cov npoo du ua tiav: ** Feem ntau muaj smoother sab hauv thiab sab nraud dua seamless yeeb nkab .

{{0 {}}} ** Dab tsi ntawm cov kav dej ERW? **
* ** WELD kab kev pheej hmoo: ** Weld Seam yog qhov tsis muaj zog yog tias kev sib cav sib ceg yog muaj kev tswj hwm thiab kev kuaj xyuas kom nruj thiab tshuaj xyuas (ndt).
* ** Cheeb Tsam Kub (Haz)
* ** TSIS TXHOB RAU QHOV TSEEB: ** Feem ntau tsis pom zoo rau qhov tseem ceeb tshaj plaws, cov yeeb nkab kev pabcuam kev pabcuam siab tshaj plaws uas yog qhov tsim nyog los ntawm nws homogeneous qauv.
* ** Lub peev xwm rau kev lamination discomps: ** Thaum pib los ntawm cov hlau hlau, txawm tias qhov no cuam tshuam rau lwm cov yeeb nkab welded dhau.
* ** Qhov chaw tsis txaus ntseeg sab saum toj: ** Cov nplaim me me flaws xws li Weld kab yuav tshwm sim, uas feem ntau yuav tsum tau tshem tawm .
