12Cr1MoV ngongo kōhua teiteii whakawhanakehia mai i te maitai 12xm taketake (0.5% Cr-Mo-V) ki te 12x1m (1% Cr-Mo-V) maitai ma te whakanui ake i te ihirangi Cr.Te hanganga matū o12Cr1MoV Alloy Tube Steel Seamlesshe ngawari, he iti iho i te 2% te katoa o nga ihirangi koranu, a he tino pai te tukanga me nga ahuatanga o te tinana.I tenei wa, kua whakarārangihia i roto i te paerewa putorino maitai mo te kohua teitei i Haina (GB5310-2008).Ko nga tohu maitai rite e whakamahia whanuitia ana ki waho ko te ASTM a405 p24 (1% CrMoV, USA), bs3604 (0,5% CrMoV, l% CrMoV, UK), din13crmov42, 10crmosiv7 (Germany), etc.
I tenei wa,12Cr1MoV Paipa Tira KorekoreKei te whakamahia nuitia i roto i te Superheater, te pane me te rere mamaoa matua o te pehanga teitei, te pehanga ultra-tiketike me nga kohua teihana hiko subcritical i te kainga me waho.Ko tenei rino tetahi o nga mea matua o te tipu hiko me te kohua i roto i te ahumahi hiko o Haina.
I tenei wa,12Cr1MoV ngongo maitai korekoreKa whakamahia te nuinga i roto i nga waahanga e whai ake nei:
(1) I te nuinga o te waa mo te putorino superheater, te putorino hau, te putorino matua, te putorino whakamahana me etahi atu waahanga o nga taputapu kohua, ina koa i roto i te pehanga teitei me te ultra-high-pressure boiler, 12Cr1MoVG iti koranu maitai wera-ātete whakamahia whānuitia.
(2) Ko te nuinga o te whakamahi mo te rakau matua,] impeller, rotor, here (bolt and nut), cylinder, nozzle chamber, lubricating valve, diaphragm and some blades of steam turbine.
(3)I whakamahia te nuinga ki te whakaiti i te pāmahana mahi o te rotor me te mata i roto i te miihini hau wera ki te 550 ℃, kia rite ki te whakawhānui i te tono o te iti koranu maitai wera-ātete i roto i te pūkaha hau.
(4)Ka taea te whakamahi ki te hanga i te rotor turbine hau, impeller, fastener me etahi atu waahanga me te pāmahana mahi i raro i te 570 ℃.
(5) Te nuinga whakamahia mo te hanga putorino oumu, whakawhiti wera me etahi atu putorino mata whakawera i roto i te taputapu matū me te hinu.
