Zofunikira paukadaulo wamapaipi a flange (kuphatikiza zidutswa zopukutira ndi zopindidwa)

Zofunikira zaukadaulo zamapepala a flange(kuphatikizapozachinyengondiadagulung'undisa zidutswa).
1.The kalasi ndi luso zofunika zazojambula(kuphatikizapozidutswa zopukutira ndi zopindidwa) adzakwaniritsa zofunikira za JB4726-4728.
2.Kuthamanga mwadzina PN 0.25 MP 1.0 MPa carbon zitsulo ndi austenitic zosapanga dzimbirizopangira zitsuloanalola kugwiritsa ntchito mlingo Ⅰ forgings.
3.Kuphatikiza pazotsatirazi, kukakamizidwa mwadzina kwa PN 1.6 MPa mpaka 6.3 MPa forgings kudzagwirizana ndi Ⅱ mlingo kapena pamwamba pa mlingo Ⅱmilingo ya forgings.
4.Mu chimodzi mwa zotsatirazi ayenera mogwirizana ndi lamulo la Ⅲ ndizojambula: (1) kuthamanga mwadzina PN acuity 10.0 MPakupanga flange;(2) chromium-molybdenumzopangira zitsulondi kuthamanga mwadzina PN> 4.0MPa; (3) ferriticzopangira zitsulondi kuthamanga mwadzina PN> 1.6MPa ndi kutentha ntchito ≤-20 ℃.

Buttkuwotcherera ndi khosi, kuwotcherera lathyathyathya ndi khosi, kuwotcherera zitsulondiflange ya ulusinthawi zambiri amapangidwa ndi kupanga kapenakuthamanga kwa magaziprocess.Pamene zitsulo mbale kapena gawo zitsulo ntchito, zofunika zotsatirazi ziyenera kukumana:
1.Chitsulo mbale adzakhala anayendera akupanga popanda stratification chilema;
2.Zidulidwe m'mizere yozungulira chitsulo, ndikuwotcherera mu mphete popinda, ndikupanga pamwamba pa chitsulo kukhala silinda ya mphete.flanges ndi makosi;
3.Kuwotcherera kokwanira kolowera kumatengedwa kuti kumawotcherera matako a mphete;
4.Kuwotcherera matako kwa mpheteyo kudzachitika pambuyo pa kuwotcherera kutentha ndikuzindikira 100% X-ray kapena ultrasonic flaw kuzindikira, ndipo X-ray yozindikira zolakwika idzakwaniritsa zofunikira za kalasi II za JB4730 ndipo kuzindikira zolakwika za akupanga kudzakumana ndi kalasi yoyamba. Zofunikira za JB4730.
