1. Ngokomgangatho woshishino lomatshini, iintlobo zeflange zezi: uhlobo lweplatei-flange ene-welding, i-butt-welded flange, flange ebalulekileyo, i-butt-welding-welding-plate uhlobo lwe-sleeve flange evulekileyo, i-flange-welded-ring-plate uhlobo lwe-sleeve flange ekhululekileyoumkhono weflange, isiciko seflange.
2. Uhlobo lweFlangengokwesiqhelo kushishino lweekhemikhali: ipleyiti flatwelding flange(PL), eneflethiukuwelda intamo flange(SO), i-flange edibeneyo (IF), i-flange ene-threaded diameter (Th), kunye ne (WN) i-flange ye-butt welding,socket welding flange(SW)umsesane we-welding flat okhululekileyo(PJ/RJ), i-flange cover (BL), i-lining flange cover (BL (S)).
3. Ngokomgangatho wesizwe, iintlobo zeflange zezi: uhlobo lweplate flatwelding flange, intamo ithe tyabawelding flange, impundu yentamowelding flange, flange ebalulekileyo, iflange enemisonto, intamo yesokethi ye-welding flange, i-butt welding ring neck ekhululekileyo ene-sleeve flange, i-butt ye-welding ring plate uhlobo olukhululekile lwe-sleeve flange, i-flanges ipleyiti yohlobo lwe-sleeve flange ekhululekile, i-flanges.
4. Ngokomgangatho woshishino lwepetrochemical, iiflange zinokuhlulwa zibeiiflange ezisicaba(SO), ii-butt-welded flanges (WN), i-threaded flanges (PT), i-socket welded flanges (SW), i-sleeve flanges ekhululekile (LJ), kunye ne-flange caps (engachazwanga kwitheyibhile).
