4. Flange ntsuam xyuas (los yog chav kawm): Rau ASME flanges, qhov ntsuas tau nyob ntawm 150 txog 2500; rau JIS B2220 flanges thiab KS1503 flanges, qhov kev ntsuam xyuas tuaj yeem nyob ntawm 5k txog 30k; rau PN 6 rau PN 100 rau European thiab Lavxias-tus qauv flanges (DIN, UNI, EN 1092-1, GOST 12820 / 12821-80); thiab rau Chav Kawm 600/3, 1000/3, 1600/3, 2 (South African qauv rau flanges)
5. Lub sijhawm ntev ntawm cov yeeb nkab (rau vuam caj dab thiab lub qhov (socket) vuam flanges)
6. Flange flange hom (FF; RF, RTJ): Raws li ASME B16.5, lub ntsej muag tsa ceg yog tus qauv tig rau flanges (kev sib txawv, xws li RTJ lossis lub ntsej muag tiaj tus FF, yuav tsum tau txiav txim tshwj xeeb)
7. Flange nto tiav (nqus, Tshuag, concentric serrated, thiab lwm yam)
8. Cov khoom siv qib (forged carbon, stainless, duplex, nickel-alloy steels lossis, cov ntaub ntawv tsis-ferrous li cupronickel, tooj liab, txhuas, thiab tooj liab)
