12Cr1MoV ityhubhu yebhoyila yoxinzelelo oluphezuluyaphuhliswa kwintsimbi yokuqala ye-12xm (0.5% Cr-Mo-V) ukuya kwi-12x1m (1% Cr-Mo-V) yensimbi ngokunyusa umxholo weCr.Ukwakhiwa kweekhemikhali ze12Cr1MoV Ingxubevange yentsimbi engenamthungoilula, umxholo we-alloy iyonke ingaphantsi kwe-2%, kwaye inenkqubo egqwesileyo kunye neempawu zomzimba.Okwangoku, idweliswe kumgangatho wombhobho wentsimbi ongenamthungo kwibhoyila yoxinzelelo oluphezulu eTshayina (GB5310-2008).Amabakala entsimbi afanayo asetyenziswa ngokubanzi kumazwe aphesheya abandakanya i-ASTM a405 p24 (1% CrMoV, USA), bs3604 (0,5% CrMoV, l% CrMoV, UK), din13crmov42, 10crmosiv7 (eJamani), njl.
Ngoku,12Cr1MoV Umbhobho wentsimbi ongenamthungoisetyenziswa kakhulu kwi-Superheater, i-header kunye ne-conduit ephambili yomphunga yoxinzelelo oluphezulu, uxinzelelo lwe-Ultra-high kunye ne-subcritical station boilers kwi-boilers yasekhaya nakwamanye amazwe.Le ntsimbi ibe yenye yezinto eziphambili zeplanti yamandla kunye nebhoyila kwishishini lamandla laseTshayina.
Ngoku,12Cr1MoV iThubhu yentsimbi engenamthungoisetyenziswa ikakhulu kule miba ilandelayo:
(1)Ikakhulu isetyenziselwa umbhobho we-superheater, umbhobho womoya, umbhobho oyintloko womphunga, umbhobho wokufudumeza umbhobho kunye nezinye iindawo zebhoyila, ngakumbi kwibhoyila yoxinzelelo oluphezulu kunye ne-ultra-high-pressure, i-12Cr1MoVG i-alloy low-alloy-resistant steel isetyenziswa kakhulu.
(2)Ikakhulu isetyenziselwa ishafti engundoqo,] i-impeller, rotor, fastener (ibholiti kunye nenati), isilinda, igumbi lombhobho, ivalve yokuthambisa, idiaphragm kunye nezinye izixhobo zeblade zeinjini yomphunga.
3
(4) Ingasetyenziselwa ukwenza i-rotor ye-injini yegesi, i-impeller, i-fastener kunye nezinye iindawo ezinobushushu obusebenzayo obungaphantsi kwe-570 ℃.
(5)Ikakhulu isetyenziselwa ukwenza umbhobho wesithando somlilo, isitshintshi sobushushu kunye neminye imibhobho yomphezulu wokufudumeza kwiikhemikhali kunye nezixhobo zepetroleum.
