Izidingo zobuchwepheshe zeipayipi flange forgings(kuhlanganiseumgunyathifuthiizingcezu ezigoqiwe).
1.Ibanga kanye nezidingo zobuchwepheshe zeama-forgings(kuhlanganiseizingcezu ezigoqiwe nezigoqiwe) izohlangabezana nezidingo ezihambisanayo ze-JB4726-4728.
2.Ukucindezela okuzisholo okungu-PN 0.25 MP 1.0 MPa carbon steel kanye ne-austenitic stainlessizinsimbi zensimbikuvunyelwe ukusetshenziswa kwezinga Ⅰ zokubumba.
3.Ngaphezu kwalezi zinhlinzeko ezilandelayo, ukucindezela okulinganiselwe kwe-PN 1.6 MPa kuya ku-6.3 MPa okukhohlisayo kuzohambisana nezinga Ⅱ noma ngaphezulu kwezinga Ⅱamazinga forgings.
4.Kokunye kwalokhu okulandelayo kufanele kuhambisane nemfuneko Ⅲ kanyeama-forgings: (1) ingcindezi yegama le-PN acuity 10.0 MPaukwakhiwa kwe-flange;(2) i-chromium-molybdenumizinsimbi zensimbingokucindezela okulinganiselwe okungu-PN>4.0MPa;(3) i-ferriticizinsimbi zensimbienengcindezi encane PN>1.6MPa kanye nezinga lokushisa lokusebenza ≤-20 ℃.

Izinqeukushisela ngentamo, welding flat ngentamo, i-socket weldingfuthii-flange enentambongokuvamile zenziwa ngokukhwabanisa nomaukuzungeza ukugoqainqubo.Lapho kusetshenziswa ipuleti lensimbi noma ingxenye yensimbi, lezi zidingo ezilandelayo kufanele zihlangatshezwe:
1.Ipuleti lensimbi lizohlolwa nge-ultrasonic ngaphandle kwesici se-stratification;
2.Izosikwa ibe imicu eduze kwendlela yokugingqa yensimbi, futhi ishiselwe ibe yindandatho ngokugoba, futhi yenze ubuso bensimbi bube isilinda esiyingini. Amapuleti ensimbi akufanele afakwe ngomshiniama-flange anentamo;
3.I-weld yokungena egcwele izosetshenziswa ukuze kushiselwe izinqe iringi;
4.I-butt weld yeringi izokwenziwa ukwelashwa kokushisa kwangemva kokushiselwa futhi ithole u-100% we-X-ray noma i-ultrasonic flaw, futhi ukutholwa kwe-X-ray flaw kuzohlangabezana nezimfuneko ze-class II ze-JB4730 futhi ukutholwa kwamaphutha kwe-ultrasonic kuzohlangabezana nekilasi I. izidingo ze-JB4730.
