I-FRP Flange
Incazelo Yomkhiqizo
Amaflange e-FRP (Fiberglass Reinforced Plastic) ayizixhumi ezimise okwendandatho ezisetshenziselwa ukuhlanganisa amapayipi, amavalvu, amaphampu, noma ezinye izinto zokusebenza ukuze kwakhiwe uhlelo oluphelele lwamapayipi. Zenziwe ngezinto eziyinhlanganisela ehlanganisa imicu yengilazi njengezinto eziqinisayo kanye ne-synthetic resin njenge-matrix. Zenziwa kusetshenziswa izinqubo ezinjengokubumba, ukubeka izandla, noma ukusonteka kwe-filament.
Izici Zomkhiqizo
Ngenxa yokwakheka kwawo okuyingqayizivele, ama-FRP flange anikeza izinzuzo ezibalulekile ngaphezu kwama-flange ensimbi endabuko:
- Ukumelana Nokugqwala Okuhle Kakhulu: Isici esiphawuleka kakhulu sama-FRP flange amandla awo okumelana nokugqwala okuvela emithonjeni yamakhemikhali ehlukahlukene, okuhlanganisa ama-asidi, ama-alkali, usawoti, nezinyibilikisi zemvelo. Lokhu kuwenza asetshenziswe kabanzi ezindaweni lapho kuhanjiswa uketshezi olubolayo, njengasezimbonini zamakhemikhali, zikaphethiloli, ezensimbi, zamandla, ezekhemisi nezokudla.
- I-Lightweight kanye namandla Aphakeme: Ukuminyana kwe-FRP ngokuvamile kungu-1/4 kuya ku-1/5 kuphela wensimbi, kodwa amandla ayo angaqhathaniseka. Lokhu kwenza kube lula ukuzithwala nokuzifaka, futhi kunciphisa umthwalo ophelele ohlelweni lwamapayipi.
- I-Insulation Kagesi Enhle: I-FRP iyimpahla engeyona e-conductive, enikeza ama-FRP flanges izindawo ezinhle kakhulu zokuvala ugesi. Lokhu kubalulekile ezindaweni ezithile ukuvimbela ukugqwala kwe-electrochemical.
- I-High Design Flexibility: Ngokulungisa ifomula ye-resin kanye nokuhlelwa kwemicu yengilazi, ama-FRP flange angenziwa ngokwezifiso ukuze ahlangabezane nezidingo ezithile zokushisa, ingcindezi, nokumelana nokugqwala.
- Izindleko Zokulungisa Eziphansi: Ama-FRP flange awagqwali noma akakali, okuholela empilweni ende yesevisi futhi ehlisa kakhulu izindleko zokulungisa nokushintsha.
Uhlobo Lomkhiqizo
Ngokusekelwe kunqubo yabo yokukhiqiza kanye nesakhiwo sesakhiwo, ama-FRP flange angahlukaniswa ngezinhlobo eziningana:
- I-One Piece (Integral) Flange: Lolu hlobo lwakhiwe njengeyunithi eyodwa enomzimba wepayipi, enikeza isakhiwo esiqinile esifanele izicelo zokucindezela okuphansi kuya kokuphakathi.
- I-Lose Flange (I-Lap Joint Flange): Iqukethe indandatho ye-flange evulekile, ezungeza ngokukhululekile kanye nesiphetho esigxilile sepayipi. Lo mklamo usiza ukufakwa, ikakhulukazi ekuxhumekeni kwamaphoyinti amaningi.
- I-Blind Flange (I-Flange Engenalutho/I-End Cap): Isetshenziselwa ukuvala ukuphela kwepayipi, ngokuvamile ukuhlola uhlelo lwamapayipi noma ukugcina isixhumi esibonakalayo.
- I-Socket Flange: Ipayipi lishuthekwa endaweni engaphakathi ye-flange futhi lixhunywe ngokuphephile ngokusebenzisa i-adhesive bonding noma izinqubo zokusonta, okuqinisekisa ukusebenza kahle kokuvala.

Izicelo Zomkhiqizo
Ngenxa yokumelana nokugqwala okukhethekile namandla angasindi, ama-FRP flange asetshenziswa kabanzi ku:
- Imboni Yamakhemikhali: Ngamapayipi athutha amakhemikhali agqwalayo njengama-asidi, ama-alkali, nosawoti.
- Ubunjiniyela Bezemvelo: Ekuhlanzeni amanzi angcolile kanye nemishini yokususa igesi ye-flue desulfurization.
- Imboni Yamandla: Okokupholisa amanzi kanye nezinhlelo ze-desulfurization/denitrification ezitshalweni zikagesi.
- Unjiniyela Wasolwandle: Ekukhishweni kukasawoti emanzini olwandle nasezinhlelweni zamapayipi ngomkhumbi.
- Izimboni Zokudla Nemithi: Ngemigqa yokukhiqiza edinga ukuhlanzeka okuphezulu kwempahla.
