Mwachidule
Timatsata mfundo za kasamalidwe ka "Quality ndipamwamba kwambiri, Kampani ndiyabwino kwambiri, Track Record ndiyoyamba", ndipo tidzapanga ndikugawana bwino ndi onse ogula Seamless Steel Pipe. Zogulitsa zathu zimadziwika kwambiri komanso zodalirika ndi ogwiritsa ntchito ndipo zimatha kukwaniritsa zosowa zachuma komanso zachikhalidwe mosalekeza. fakitale yathu chimakwirira kudera la mamita lalikulu 12,000, ndipo ali ndodo ya anthu 200, pakati pawo pali akuluakulu 5 luso. Takhala akatswiri pa producing.We tsopano ali ndi luso lolemera pakugulitsa kunja. Takulandirani kuti mutilankhule ndipo kufunsa kwanu kudzayankhidwa posachedwa.

Onse safunikira chithandizo cha kutentha komanso kuyesa kwamphamvu, ndipo A106 Gr.B pafupifupi 20# muzinthu zamakina ndi makina, kotero zitsulo ziwirizi nthawi zambiri zimakhala zolowa m'malo.
Kugwiritsa ntchito
Chitoliro chopanda chitsulo chopanda ntchito cha ASTM A106, choyenera kutentha kwambiri
