Flange, yomwe imadziwikanso kuti flange kapena flange. Flange ndi chigawo chomwe chimagwirizanitsa ma shafts ndipo chimagwiritsidwa ntchito polumikiza mapeto a chitoliro; Zothandizanso ndi ma flanges pa polowera ndi potuluka zida, zomwe zimagwiritsidwa ntchito polumikiza zida ziwiri, monga ma flanges a gearbox. Kulumikizana kwa flange kapena kuphatikizika kwa flange kumatanthawuza kulumikizana komwe kumatha kupangidwa ndi kuphatikiza kwa ma flanges, ma gaskets, ndi mabawuti olumikizidwa palimodzi ngati chosindikizira. Pipeline flange imatanthawuza kuphulika kwa mapaipi omwe amagwiritsidwa ntchito popanga mapaipi, ndipo akagwiritsidwa ntchito pazida, amatanthawuza kulowera ndi kutulutsa kwa zida. Malinga ndi milingo yamphamvu yofananira ya mavavu, ma flange okhala ndi milingo yosiyanasiyana ya kuthamanga amapangidwa mumayendedwe a mapaipi. Pachifukwa ichi, mainjiniya aku Germany ochokera ku Ward WODE amayambitsa milingo yamphamvu ya flange yomwe imagwiritsidwa ntchito molingana ndi miyezo yapadziko lonse lapansi:

Malinga ASME B16.5, zitsulo flanges ndi 7 kuthamanga mlingo: Class150-300-400-600-900-1500-2500 (logwirizana dziko muyezo flanges ndi PN0.6, PN1.0, PN1.6, PN2.5, PN4 .0, PN6.4, PN10, PN16, PN25, PN32Mpa ratings)

Kupanikizika kwa flange kumamveka bwino. Ma Flanges a Class300 amatha kupirira kupsinjika kwambiri kuposa Class150 chifukwa ma flange a Class300 amafunika kupangidwa ndi zida zambiri kuti athe kupirira kupsinjika kwakukulu. Komabe, mphamvu yopondereza ya flange imakhudzidwa ndi zinthu zingapo. Kuthamanga kwa flange kumawonetsedwa mu mapaundi, ndipo pali njira zosiyanasiyana zowonetsera kupanikizika. Mwachitsanzo, matanthauzo a 150Lb, 150Lbs, 150 #, ndi Class150 ndi ofanana.
