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 oxegayo, i-flange-welded ring-plate uhlobo lomkhono ovulekile, uhlobo lwe-ring-plate ene-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 izinqe evulekile (PJ/SE),indandatho ye-welding flat i-flange evulekile(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 flatwelding 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 kuthebula).
