Kutumiza Kwatsopano kwa China ASTM A335 P91 Alloy Seamless Steel Pipe ya Boiler
Mwachidule
Timathandizira ogula athu ndi zinthu zabwino kwambiri komanso ntchito zapamwamba kwambiri. Kukhala katswiri wopanga m'gawo lino, ife tsopano analandira wopambana zothandiza ntchito popanga ndi kuyang'anira chitoliro aloyi zitsulo ntchito kutentha kwambiri ndi utumiki kuthamanga kuthamanga, Tikhoza makonda katundu malinga ndi zofuna zanu ndipo tikhoza kunyamula kwa inu pamene. inu kuyitanitsa. "Pangani akazi kukhala okongola kwambiri" ndi malingaliro athu ogulitsa. "Kukhala makasitomala odalirika komanso omwe amakonda makasitomala" ndicho cholinga cha kampani yathu. Takhala osamalitsa gawo lililonse la ntchito yathu. Timalandila abwenzi moona mtima kukambirana bizinesi ndikuyamba mgwirizano. Tikukhulupirira kuti tidzalumikizana ndi anzathu m'mafakitale osiyanasiyana kuti tipange tsogolo labwino.
Kugwiritsa ntchito
Amagwiritsidwa ntchito kwambiri popanga chitoliro chapamwamba cha aloyi chitsulo chowotcha, chitoliro chosinthanitsa kutentha, chitoliro champhamvu cha nthunzi chamafuta ndi mafakitale amafuta.
Main Grade
Kalasi ya apamwamba aloyi chitoliro: P1, P2, P5, P9, P11, P22, P91, P92 etc.
