Hot zogulitsa China Hot-yokulungidwa Seamless Zitsulo Mapaipi Zomanga Zomangamanga Zopanda Chitoliro Mpweya wa Carbon Steel
Mwachidule
Poganizira mawuwa, takhala m'gulu la opanga zida zaukadaulo, zotsika mtengo, komanso zopikisana pamitengo ya Mapaipi Opanda Zitsulo Otentha, Takulandilani ogula onse abwino kuti azilumikizana nafe zambiri zamayankho ndi malingaliro! Timasunga khama la nthawi yayitali komanso kudzidzudzula, zomwe zimatithandiza ndi kusintha nthawi zonse. Timayesetsa kukonza magwiridwe antchito a makasitomala kuti tisunge ndalama kwa makasitomala. Timayesetsa kuti zinthu ziziyenda bwino. Sitikhala molingana ndi mwayi wakale wanthawi ino.
Kugwiritsa ntchito
Chitoliro chopanda chitsulo chopanda ntchito cha ASTM A106, choyenera kutentha kwambiri
Main Grade
Gulu lazitsulo zapamwamba za carbon structural: G.A,GR.B,GR.C
