China Wopanga Ku China Factory Seamless Hollow Section Aloyi Zitsulo Pipe chubu ASTM A335 Kutentha-kukana Gasi Mpweya Boiler Mafuta osweka
Mwachidule
Timadalira luso lolimba laukadaulo ndikupanga matekinoloje apamwamba kwambiri kuti akwaniritse zofunikira za China Manufacturer wa ASTM A335 Heat-Resisting Seamless Alloy Steel Pipe, Timaika patsogolo kusangalatsa kwamakasitomala komanso kusangalatsa kwamakasitomala ndipo chifukwa cha izi timatsata njira zowongolera zabwino. Tsopano tili ndi malo oyesera m'nyumba momwe mayankho athu amayesedwa pagawo lililonse pamagawo osiyanasiyana opangira. Pokhala ndi matekinoloje aposachedwa, timathandizira makasitomala athu kukhala ndi makonda otulutsa. Dzina lakampani, nthawi zonse limayang'ana mtundu ngati maziko a kampani, kufunafuna chitukuko kudzera muukadaulo wapamwamba, kutsata miyezo ya kasamalidwe kaukadaulo ya ISO mosamalitsa, kupanga kampani yapamwamba ndi mzimu wosonyeza kukhulupirika ndi chiyembekezo.
Pali kuyambitsa kwa T91/P91 aloyi zitsulo boiler chitoliro
1. Chitsulo Kalasi Chiyambi
T91 / P91 ndi chitsulo chosagwira kutentha kwa ferritic, ndi labotale ya dziko la oak ridge m'zaka za m'ma 1970 idayamba kufufuza ndi chitukuko, ndipo mu 1983 ku ASME, dziko lathu mu 1995 mpaka chitsulo mu GB 5310 muyezo, mtundu ngati 10 cr9mo1vnbT91. / P91 zitsulo anali 9 cr1mo (T9), pa maziko a zitsulo, chiyero, chabwino crystallization zitsulo luso, komanso aloyi yaying'ono ndi ankalamulira Kugubuduza ndi ankalamulira kuzirala luso, anayamba mbadwo watsopano wa kutentha kusamva zitsulo aloyi. Chitsulocho chimakhala ndi zinthu zambiri zamakina, kutentha kwambiri kukalamba pambuyo pa kukhazikika, ndi ntchito yowotcherera ndi ntchito yabwino, yoyenera kutentha kwakukulu kwa gawo la zipangizo.

Kugwiritsa ntchito
Amagwiritsidwa ntchito kwambiri popanga chitoliro chapamwamba cha aloyi chitsulo chowotcha, chitoliro chosinthira kutentha, chitoliro champhamvu cha nthunzi chamafuta ndi mafakitale amafuta.
