Izidingo zobuchwepheshe zeUkukhokhiswa kwe-Flange Flange(kufaka phakathiowakhelwayona-izingcezu ezigoqiwe).
1.Izidingo zebanga nezobuchwepheshe zeukuthethelelwa(kufaka phakathiizingcezu ezakhiwe futhi zagoqa) izohlangabezana nezidingo ezihambisanayo zeJB4726-4728.
2.Ingcindezi ye-Ominal Pn 0.25 MP 1.0 MPA Carbon Steel ne-Auntenitic StainlessUkukhokhiswa kwensimbikuvunyelwe ukusetshenziswa kwezikhombisi ze-level ⅰ.
3.Ngaphezu kwezinhlinzeko ezilandelayo, ingcindezi yokuqokwa kwe-PN 1.6 MPA kuya ku-6.3 MPA Ukukhokhiswa kuzohambisana ne-② level noma ngaphezuluAmazinga okuthethelelwa.
4.Kokunye kokulandelayo kufanele kuvume ngesidingo se- ⅲ futhiukuthethelelwa: (1) ingcindezi yokuqothuka PN Acuity 10.0 MPAUFlange Ucela; (2) i-chromium-molybdenumUkukhokhiswa kwensimbiNge-Ominal Pressure PN> 4.0MPA; (3) FerriticUkukhokhiswa kwensimbiNge-Pressure Pressure PN> 1.6MPA kanye nokushisa okusebenzayo ≤-20 ℃.

Isixubukiukufudumeza ngentamo, ukufudumala okufuywayo ngentamo, socket weldingna-intambo ethambilengokuvamile zenziwa ngokudala nomaUkwakha UkugoqaInqubo.Kwathishwa ipuleti lensimbi noma insimbi yensimbi, izidingo ezilandelayo kumele zihlangatshezwe:
1.Ipuleti lensimbi lizohlolwa yi-ultrasonic ngaphandle kwesici sokuhlanza;
2.Izosikwa ibe yimichilo eceleni kwensimbi egoqiwe yensimbi, futhi ifakwe kwindandatho ngokugoba, futhi yenza ingaphezulu lefomu lensimbi kube yisilinda se-cylinder of the ring.Steel angeke afakwe emnyanjeni ngqoAma-Flanges anezintambo;
3.I-penetration ephelele izokwamukelwa nge-butt weld yendandatho;
4.I-Butt Weld yendandatho izobhekana nokwelashwa okushisa ngemuva kweWeld futhi yenze i-100% X-ray noma ukutholwa kwe-FAFICE ye-ultrasonic, kanye nokutholwa kwe-X-ray Fice Izidingo zeJB4730.
