ASME SA387 GR.22 CL2 Boiler ndi mbale ya Pressure Vessel Steel

ASME SA387 ndi mbale yachitsulo ya chromium molybdenum alloy yomwe imapangidwa makamaka kuti ikhale yowotchera komanso zotengera zopanikizika zomwe zimapangidwa ndi kutentha kwambiri.
ASME SA387 GR.22 CL2 Mafotokozedwe a mbale ya Pressure Vessel Steel:
SA 387 GR.22 CL.2 PLATE ili ndi chromium ya 2.25% ndi molybdenum ya 1% ndipo imatha kugwira ntchito mu kutentha kwa 600 Deg C mozungulira bwino. Ma mbale achitsulo a molybdenum ndi chromium akugwira ntchito bwino pa kutentha kosiyana nthawi zonse akupereka ntchito yabwino kwambiri. Kuphatikiza kwa molybdenum mu aloyi ya SA 387 kukuwonjezera mphamvu zama mbale pa kutentha kwakukulu. Komanso, ikupereka kuthekera kwabwino kwa dzimbiri komanso makutidwe ndi okosijeni komanso powonjezera kupsinjika kwa lattice. Izi zimalepheretsa kuti chitsulo chisasungunuke komanso chimapangitsa kuti mpweya usasungunuke ndipo umakhala wabwino kwambiri polimbana ndi kutentha. Komanso, ili ndi weldability wabwino. Chifukwa chake, mbale iyi ndiyofunika kwambiri padziko lonse lapansi.

  • A5.23/A5.23M: Maelekitirodi achitsulo otsika a alloy a fulxes owotcherera arc omira.
  • A5.28/A5.28M: Kwa kuwotcherera kwa arc yotetezedwa ndi gasi
  • A5.29/A5.29M: Kwa kuwotcherera kozungulira kozungulira.

Chithandizo cha Kutentha kwa SA387 Chrom Moly Alloy Steel Plate

Chitsulo cha Chrome moly alloy zitsulo pansi pa ASME SA387 chidzaphedwa chitsulo, ndi kutenthedwa ndi kutentha, kutentha, kutentha ndi kutentha. Kapena ngati wogula avomereza, kuziziritsa kofulumira kuchokera ku kutentha kozizira kwambiri ndi kuphulika kwa mpweya kapena kuzimitsa kwamadzimadzi, kutsatiridwa ndi kutentha, kutentha kochepa kudzakhala monga pansipa:
Gulu Kutentha, °F [°C]
2, 12 ndi 11 1150 [620]
22, 22L, 21, 21L ndi 9 1250 [675]
