Seamless alloy steel pipe stockChithunzi cha ASTM A335 P91, chitoliro chachitsulo chosasunthika chomwe chimagwiritsidwa ntchito m'machubu otenthetsera, machubu osinthira kutentha ndi mafakitale ena, chitha kugwiritsidwa ntchito ngati mapaipi achitsulo otenthetsera kutentha kwambiri komanso otenthetsera m'ma boiler a subcritical ndi supercritical okhala ndi kutentha kwa khoma ≤625 ° C, komanso makhoma Otentha kwambiri ndi mapaipi a nthunzi okhala ndi kutentha ≤600 ℃ angagwiritsidwenso ntchito ngati zosinthira mphamvu za nyukiliya ndi machubu a ng'anjo yamafuta amafuta.
ASTM A335 P91 ndi zitsulo zotentha kwambiri zomwe zimakhala ndi chitsulo chochepa cha chromium-molybdenum. Amagwiritsidwa ntchito kwambiri m'mapaipi ndi zida pansi pa kutentha kwakukulu komanso malo othamanga kwambiri, monga petrochemical, mphamvu yamagetsi, zomera za nyukiliya ndi madera ena. Zigawo zazikulu za nkhaniyi ndi chromium, molybdenum, mkuwa, manganese, pakachitsulo, phosphorous, sulfure ndi zinthu zina. Zomwe zili mu chromium ndi molybdenum ndizokwera kwambiri, zomwe zimatha kusintha kutentha kwambiri komanso kukana kwa okosijeni kwa zinthuzo.
Zida za ASTM A335 P91 zili ndi makina abwino kwambiri ndipo zimatha kukhalabe ndi mphamvu komanso kulimba pansi pa kutentha kwambiri komanso malo opanikizika kwambiri. Zinthuzi zimalimbananso kwambiri ndi okosijeni, zomwe zimatha kuwonjezera moyo wautumiki wa mapaipi ndi zida. Kuphatikiza apo, zinthuzo zimakhalanso ndi ntchito yabwino yowotcherera, zomwe zimapangitsa kuti zomangamanga ndi kukonza zikhale zosavuta.
Chifukwa zinthu za ASTM A335 P91 zili ndi zinthu zabwino kwambiri izi, zimagwiritsidwa ntchito kwambiri m'malo ena otentha komanso kuthamanga kwambiri. Mwachitsanzo, m'makampani a petrochemical, mapaipi ndi zida zopangidwa ndi ASTM A335 P91 zimatha kupirira kukokoloka kwamankhwala ndi dzimbiri pansi pa kutentha kwambiri komanso kupanikizika, kuonetsetsa kuti zida zikuyenda bwino. M'minda ya magetsi ndi zomera mphamvu nyukiliya, mapaipi ndi zida zopangidwa ASTM A335 P91 akhoza kupirira dzimbiri ndi kukokoloka kwa nthunzi ndi nthunzi madzi ndi TV zina pansi kutentha ndi kukakamizidwa, kuonetsetsa ntchito bwinobwino zida.
