FRP Flange
Tlhaloso ea Sehlahisoa
Li-flange tsa FRP (Fiberglass Reinforced Plastic) ke likhokahano tse bōpehileng joaloka lesale tse sebelisetsoang ho kopanya liphaephe, li-valve, lipompo kapa lisebelisoa tse ling ho theha tsamaiso e feletseng ea liphaephe. Li entsoe ka thepa e kopantsoeng e nang le likhoele tsa khalase e le thepa e matlafatsang le resin ea maiketsetso joalo ka matrix. Li etsoa ho sebelisoa mekhoa e kang ho bōptjoa, ho beha matsoho, kapa ho pota-pota ha filament.
Likarolo tsa Sehlahisoa
Ka lebaka la sebopeho sa bona se ikhethileng, li-flange tsa FRP li fana ka melemo e mengata ho feta li-flange tsa tšepe tsa setso:
- Ho Hanyetsa Corrosion e Ntle ka ho Fetisisa: Ntho e hlokomelehang ka ho fetesisa ea li-flange tsa FRP ke bokhoni ba tsona ba ho hanela kutu ho tsoa mecheng e fapaneng ea mecha ea litaba ea lik'hemik'hale, ho kenyeletsoa li-acids, alkalis, matsoai le metsoako ea manyolo. Sena se etsa hore li sebelisoe haholo libakeng tseo ho tsamaisoang maro a senyang, joalo ka indastering ea lik'hemik'hale, petroleum, metallurgy, ea matla, ea meriana le ea lijo.
- Bonolo le Matla a Phahameng: Boima ba FRP hangata ke 1/4 ho 1/5 feela ea tšepe, leha ho le joalo matla a eona a ka bapisoa. Sena se etsa hore ho be bonolo ho li tsamaisa le ho li kenya, 'me se fokotsa mojaro o akaretsang tsamaisong ea liphaephe.
- Insulation e Ntle ea Motlakase: FRP ke thepa e sa sebetseng, e fanang ka li-FRP flanges thepa e ntle ea ho kenya motlakase. Sena se bohlokoa libakeng tse ikhethileng ho thibela kutu ea electrochemical.
- High Design Flexibility: Ka ho lokisa foromo ea resin le tlhophiso ea likhoele tsa khalase, li-flange tsa FRP li ka etsoa ka tloaelo ho fihlela litlhoko tse khethehileng tsa mocheso, khatello le ho hanyetsa ho bola.
- Litšenyehelo tse Tlase tsa Tlhokomelo: FRP flanges ha e ruse kapa e sekala, e lebisang ho bophelo bo bolelele ba ts'ebeletso mme e fokotsa haholo litšenyehelo tsa tlhokomelo le tse ncha.
Mofuta oa Sehlahisoa
Ho ipapisitsoe le ts'ebetso ea bona ea tlhahiso le sebopeho sa sebopeho, li-flange tsa FRP li ka aroloa ka mefuta e mengata:
- Flange e le 'Ngoe (Integral): Mofuta ona o thehoa e le setsi se le seng se nang le' mele oa pipe, se fanang ka mohaho o thata o loketseng likopo tse tlaase ho ea bohareng.
- Loose Flange (Lap Joint Flange): E na le selikalikoe se hlephileng, se bilikang ka bolokolohi le pheletso e tsitsitseng ea phala. Moralo ona o thusa ho kenya, haholo-holo likhokahanong tsa lintlha tse ngata.
- Blind Flange (Blank Flange/End Cap): E ne e sebelisetsoa ho koala pheletso ea phala, hangata bakeng sa tlhahlobo ea lipeipi kapa ho boloka sehokelo.
- Socket Flange: Peipi e kenngoa ka har'a lekhalo le ka hare la flange 'me e hokahanngoa ka mokhoa o sireletsehileng ka ho kopanya sekhomaretsi kapa mekhoa ea ho tsoelipana, ho netefatsa ts'ebetso e ntle ea ho tiisa.

Lisebelisoa tsa Sehlahisoa
Ka lebaka la khanyetso ea tsona e ikhethang ea kutu le matla a bobebe, li-FRP flange li sebelisoa haholo ho:
- Indasteri ea Lik'hemik'hale: Bakeng sa liphaephe tse tsamaisang lik'hemik'hale tse senyang tse kang li-acids, alkalis, le letsoai.
- Boenjineri ba Tikoloho: Ho hloekisa metsi a litšila le lisebelisoa tsa flue gas desulfurization.
- Indasteri ea Matla: Bakeng sa ho pholisa metsi le lits'ebetso tsa desulfurization/denitrification lifemeng tsa motlakase.
- Boenjiniere ba Metsing: Metsing ea ho ntša letsoai metsing a leoatle le tsamaiso ea lipeipi tsa likepe.
- Liindasteri tsa Lijo le Meriana: Bakeng sa mela ea tlhahiso e hlokang bohloeki bo phahameng ba thepa.
