1. Ngokwezinga lemboni yemishini, izinhlobo ze-flange yilezi: uhlobo lwepuletiflat-welded flange, i-butt-welded flange, flange ebalulekile, i-butt-welded ring-plate uhlobo lomkhono ovulekile, i-flange ene-ring-plate eyindilinga eyisicaba yohlobo oluxekethile lwe-sleeve flange, uhlobo lwepuleti eliyindilinga eline-flanged olukhululekilei-sleeve flange, ikhava ye-flange.
2. Uhlobo lwe-Flangengokwejwayelekile imboni yamakhemikhali: ipuleti flatwelding flange(PL), enefulethiwelding intamo flange(SO), i-integral flange (IF), ububanzi be-flange obucushiwe (Th), ene-(WN) yokushisela izinqe,I-socket welding flange(SW), indandatho yokushisela i-butt loose flange (PJ/SE),flat Welding ring okuxekethile flange(PJ/RJ), ikhava ye-flange (BL), ikhava ye-flange yolwelwesi (BL (S)).
3. Ngokwezinga likazwelonke, izinhlobo ze-flange yilezi: uhlobo lwe-plate flatwelding flange, igolo liphansiwelding flange, ingquza yegolowelding flange, flange ebalulekile, i-flange enentambo, i-flange ye-welding ye-neck socket, i-butt welding neck evulekile emkhono flange, ipuleti lendandatho ye-butt yensimbi yohlobo oluxekethile lwe-sleeve flange, ama-flanges amapuleti ensimbi yohlobo oluxekethile lwe-sleeve flange, ama-flange.
4. Ngokwezinga lemboni ye-petrochemical, ama-flange angahlukaniswa abeama-flange ane-welded(SO), ama-flange ane-butt-welded (WN), ama-flange anentambo (PT), ama-flange ashiselwe isokhethi (SW), imikhono emikhono exegayo (LJ), namakepisi e-flange (akucacisiwe etafuleni).
