12Cr1MoV high pressure boiler tubeyathuthukiswa kusukela kunsimbi yokuqala engu-12xm (0.5% Cr-Mo-V) kuya kunsimbi engu-12x1m (1% Cr-Mo-V) ngokukhuphula okuqukethwe kwe-Cr.Ukwakheka kwamakhemikhali weI-12Cr1MoV Ingxubevange ye-Seamless Steel Tubeilula, ingqikithi ye-alloy ingaphansi kuka-2%, futhi inenqubo enhle kakhulu kanye nezakhiwo zomzimba.Njengamanje, ifakwe kuhlu lwezinga lepayipi lensimbi elingenamthungo kubhayela wengcindezi ephezulu eChina (GB5310-2008).Amabanga ensimbi afanayo asetshenziswa kabanzi emazweni angaphandle ahlanganisa i-ASTM a405 p24 (1% CrMoV, USA), bs3604 (0,5% CrMoV, l% CrMoV, UK), din13crmov42, 10crmosiv7 (Germany), njll.
Okwamanje,12Cr1MoV Ipayipi Lensimbi Elingenamthungoisetshenziswa kakhulu ku-Superheater, unhlokweni kanye nomgudu womusi omkhulu wokucindezela okuphezulu, umfutho ophakeme kakhulu kanye nama-boilers wesiteshi samandla angaphansi kwe-subcritical ekhaya naphesheya.Le nsimbi isiphenduke enye yezinto eziphambili zemishini kagesi kanye nebhayela embonini yamandla kagesi yaseChina.
Okwamanje,12Cr1MoV Seamless Steel Tubeisetshenziswa kakhulu kulezi zici ezilandelayo:
(1)Ikakhulukazi isetshenziselwa ipayipi le-superheater, ipayipi lomoya, ipayipi lesitimu esikhulu, ipayipi lokushisisa nezinye izingxenye zemishini yokubhayela, ikakhulukazi kubhayela we-high-pressure kanye ne-ultra-high-pressure, 12Cr1MoVG insimbi ephansi yealloy engazweli ukushisa isetshenziswa kakhulu.
2
(3) Ikakhulukazi isetshenziselwa ukunciphisa izinga lokushisa elisebenzayo le-rotor kanye ne-blade enjinini yegesi eshisayo ibe ngu-550 ℃, ukuze kwandiswe ukusetshenziswa kwensimbi ephansi ye-alloy engamelana nokushisa enjini yegesi.
(4) Ingasetshenziselwa ukukhiqiza i-gas turbine rotor, impeller, fastener nezinye izingxenye ezinezinga lokushisa elingaphansi kuka-570 ℃.
(5)Ikakhulukazi esetshenziselwa ukukhiqiza ipayipi lesithando somlilo, isishintshi sokushisa namanye amapayipi angaphezulu okufudumeza kumakhemikhali nempahla kaphethiloli.
