SA387 GR.12 CL2 Pressure Vessel Steel mbale

Opangidwa kuti azigwiritsidwa ntchito pakutentha kwambiri, ASME SA387 Gulu 12 ndi chitsulo cha chrome molybdenum carbon alloy kuti chigwiritsidwe ntchito muzotengera zowotcherera zowotcherera ndi zowotchera mafakitale.
SA387 GR.12 CL2 Pressure Vessel Steel Matanthauzo:
A387 Kalasi 12 CL 1, A387 Kalasi 12 CL 2 ali pansi zitsulo specifications muyezo ASTM A387/A387M kwa chotengera chotengera zitsulo mbale, aloyi zitsulo ndi Chromium-Molybdenum.The ofanana zitsulo mbale SA387 Gulu 12 CL 1 ndi SA387 CL Gulu 2 12 zili pansi pa American zitsulo stamdard SA 387/SA 387M. Zonsezi aloyi zitsulo mbale anafuna makamaka ma boilers welded ndi kuthamanga ziwiya & akasinja.Kugudubuzika pazipita makulidwe a mbale ndi malire kokha ndi mphamvu zikuchokera kuti akwaniritse zofunika mawotchi katundu.
Kwa kukakamiza chotengera zitsulo mbale SA387 Gulu 12 CL 1, mphamvu yamakokedwe adzakhala mkati 380 kuti 550, osachepera zokolola mphamvu ndi 230 Mpa.For SA387 Gulu 12 CL 2 kuthamanga chotengera zitsulo mbale, kumakoka mphamvu ndi pa 450-585 Mpa ndi zokolola mfundo idzakhala pamwamba pa 275 Mpa. Kupatula zinthu zazikulu zisanu, Cr-Mo ilinso mu mankhwala azitsulo za alloy.

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:
