I-Flange ye-FRP
Incazelo Yomkhiqizo
Ama-flange e-FRP (i-Fiberglass Reinforced Plastic) ayizixhumi ezimise okwendandatho ezisetshenziselwa ukuhlanganisa amapayipi, ama-valve, amaphampu, noma eminye imishini ukudala uhlelo oluphelele lwamapayipi. Enziwe ngezinto ezihlanganisiwe eziqukethe imicu yengilazi njengento yokuqinisa kanye ne-resin yokwenziwa njenge-matrix. Akhiqizwa kusetshenziswa izinqubo ezifana nokubumba, ukubeka ngesandla, noma ukugoqa i-filament.
Izici Zomkhiqizo
Ngenxa yokwakheka kwawo okuyingqayizivele, ama-FRP flanges anikeza izinzuzo ezibalulekile ngaphezu kwama-flanges ensimbi endabuko:
- Ukumelana Okuhle Kakhulu Nokugqwala: Isici esiphawuleka kakhulu sama-flange e-FRP yikhono lawo lokumelana nokugqwala okuvela ezintweni ezahlukahlukene zamakhemikhali, okuhlanganisa ama-acid, ama-alkali, usawoti, kanye nezinyibilikisi eziphilayo. Lokhu kuzenza zisetshenziswe kabanzi ezindaweni lapho uketshezi olugqwala luthuthwa khona, njengasezimbonini zamakhemikhali, uphethiloli, insimbi, amandla, imithi kanye nokudla.
- Ilula Futhi Inamandla Aphezulu: Ubuningi be-FRP buvame ukuba yi-1/4 kuya ku-1/5 kuphela kunobensimbi, kodwa amandla ayo angaqhathaniswa. Lokhu kwenza kube lula ukuwathutha nokuwafaka, futhi kunciphisa umthwalo ophelele ohlelweni lwamapayipi.
- Ukufakwa Okuhle Kokugesi: I-FRP iyinto engahambisi ugesi, enikeza ama-flange e-FRP izakhiwo ezinhle kakhulu zokufakwa kogesi. Lokhu kubalulekile ezindaweni ezithile ukuvimbela ukugqwala kwe-electrochemical.
- Ukuguquguquka Okuphezulu Komklamo: Ngokulungisa ifomula ye-resin kanye nokuhlelwa kwemicu yengilazi, ama-FRP flanges angenziwa ngokwezifiso ukuze ahlangabezane nezidingo ezithile zokushisa, ingcindezi, kanye nokumelana nokugqwala.
- Izindleko Zokulungisa Eziphansi: Ama-flange e-FRP awagqwali noma angabi makhulu, okuholela empilweni yenkonzo ende futhi kunciphisa kakhulu izindleko zokulungisa nezokufaka esikhundleni.
Uhlobo Lomkhiqizo
Ngokusekelwe enkambisweni yabo yokukhiqiza kanye nesimo sesakhiwo, ama-FRP flanges angahlukaniswa ngezinhlobo eziningana:
- I-Flange Enengxenye Eyodwa (Ehlanganisiwe): Lolu hlobo lwakhiwe njengeyunithi eyodwa enomzimba wepayipi, lunikeza isakhiwo esiqinile esifanele ukusetshenziswa komfutho ophansi kuya kophakathi.
- I-Loose Flange (I-Lap Joint Flange): Yakhiwe ngendandatho ye-flange ekhululekile, ejikelezayo ngokukhululekile kanye ne-stub eqondile epayipini. Lo mklamo wenza kube lula ukufakwa, ikakhulukazi ekuxhumeni okunamaphoyinti amaningi.
- I-Flange Eyimpumputhe (I-Flange Engenalutho/Isivalo Sokuphela): Isetshenziselwa ukuvala ukuphela kwepayipi, ngokuvamile ukuhlolwa kohlelo lwepayipi noma ukubhukha isixhumi esibonakalayo.
- I-Socket Flange: Ipayipi lifakwa emgodini wangaphakathi we-flange futhi lixhunywe ngokuphephile ngezinqubo zokubopha noma zokubopha okunamathelayo, okuqinisekisa ukusebenza kahle kokuvala.

Izinhlelo Zokusebenza Zomkhiqizo
Ngenxa yokumelana nokugqwala okumangalisayo kanye namandla alula, ama-FRP flange asetshenziswa kabanzi ku:
- Imboni Yamakhemikhali: Yemipayipi ethutha amakhemikhali aqothulayo njenge-asidi, ama-alkali, nosawoti.
- Ubunjiniyela Bezemvelo: Ekwelapheni amanzi amdaka kanye nemishini yokususa igesi ephuma emanzini.
- Imboni Kagesi: Yezinhlelo zamanzi okupholisa kanye nezinhlelo zokususa i-sulfurization/denitrification ezitshalweni zikagesi.
- Ubunjiniyela Basemanzini: Ezinhlelweni zokususa usawoti emanzini olwandle kanye namapayipi emikhumbi.
- Izimboni Zokudla Nezemithi: Kwemikhiqizo edinga ubumsulwa obukhulu bezinto ezibonakalayo.
