FRP Epoxy Pipe
Incazelo Yomkhiqizo
Ipayipi le-epoxy le-FRP yaziwa ngokusemthethweni njengepayipi le-Glass Fiber Reinforced Epoxy (GRE). Kuyipayipi lezinto ezibonakalayo elisebenza kahle kakhulu, elakhiwe kusetshenziswa i-filament winding noma inqubo efanayo, enemicu yengilazi yamandla aphezulu njengento eqinisayo kanye ne-epoxy resin njenge-matrix. Izinzuzo zayo eziyinhloko zihlanganisa ukumelana nokugqwala okuvelele (ukuqeda isidingo sezingubo zokuzivikela), isisindo esilula esihlanganiswe namandla aphezulu (ukufakwa lula nokuthutha), ukuhanjiswa kwe-thermal okuphansi kakhulu (okuhlinzeka ngokufaka ukushisa okushisayo nokonga amandla), kanye nodonga lwangaphakathi olubushelelezi, olungalingani. Lezi zimfanelo zikwenza kube indawo ekahle yokufaka amapayipi okuvamile emikhakheni efana ne-petroleum, amakhemikhali, ubunjiniyela basolwandle, ukugqunywa kukagesi, nokuhlanza amanzi.
Izici Zomkhiqizo
I-FRP Epoxy Pipe (I-Glass Fiber Reinforced Epoxy, noma i-GRE) inikeza inhlanganisela ephakeme yezakhiwo uma kuqhathaniswa nezinto zendabuko:
1. Ukumelana Nokugqwala Okukhethekile
- I-Chemical Immunity: Imelana kakhulu nenhlobonhlobo yemithombo yezindaba ebolayo, okuhlanganisa ama-asidi, ama-alkali, usawoti, indle, namanzi olwandle.
- Akunasondlo: Akudingi okokuvikela kwangaphakathi noma kwangaphandle noma ukuvikelwa kwe-cathodic, okuqeda ngokuyisisekelo ukunakekelwa okuhlobene nokugqwala nobungozi.
2. Isisindo Esilula kanye Namandla Aphakeme
- Ukuminyana Okuncishisiwe: Ikala kuphela u-1/4 kuya ku-1/8 wepayipi lensimbi, okwenza kube lula kakhulu ukuhanjiswa, ukuphakamisa, nokufaka, okwehlisa izindleko zephrojekthi zizonke.
- Amandla Emishini Ephakeme: Inamandla aphezulu okudonsa, ukugoba, namandla okuthinta, ekwazi ukuphatha izingcindezi eziphezulu zokusebenza nemithwalo yangaphandle.
3. Izimo ezinhle kakhulu zeHydraulic
- I-Smooth Bore: Indawo yangaphakathi inesici sokungqubuzana esincane kakhulu, esinciphisa kakhulu ukulahlekelwa kwekhanda loketshezi kanye nokumpompa amandla uma kuqhathaniswa namapayipi ensimbi.
- I-Non-Scaling: Udonga olubushelelezi lumelana nokubambelela kwesikali, i-sediment, kanye ne-bio-fouling (njengokukhula olwandle), igcina ukusebenza kahle kokugeleza okuphezulu ngokuhamba kwesikhathi.
4. Izakhiwo ezishisayo nezikagesi
- I-Thermal Insulation: Ifaka i-thermal conductivity ephansi kakhulu (cishe u-1% wensimbi), ihlinzeka ngokufakwa okuhle kakhulu ukuze kuncishiswe ukulahlekelwa ukushisa noma ukuzuza koketshezi oludluliswayo.
- I-Electrical Insulation: Inikezela ngezakhiwo ezisezingeni eliphezulu zokuvala ugesi, ikwenze iphephe futhi ifanele ukusetshenziswa ezindaweni zamandla nezokuxhumana.
5. Ukuqina kanye Nezindleko Eziphansi Zomjikelezo Wempilo
- Impilo Emide Yesevisi: Idizayinelwe impilo yesevisi yeminyaka engama-25 noma ngaphezulu ngaphansi kwezimo zokusebenza ezijwayelekile.
- Ukunakekela Okuncane: Ngenxa yokugqwala nokumelana nokukala, isistimu ayidingi neze ukunakekelwa okujwayelekile, okuholela ezindlekweni eziphansi zomjikelezo wokuphila.

Izicelo Zomkhiqizo
- Imigqa Yokudluliswa Kwe-Voltage Ephakeme: Isetshenziswa njengamapayipi okuvikela amakhebuli kagesi angaphansi komhlaba noma ngaphansi kwamanzi.
- Izitshalo/Iziteshi Ezingaphansi: Kuqashwe ukuvikela izintambo zikagesi kanye nokulawula izintambo ngaphakathi kwesiteshi ekugqwaleni kwemvelo kanye nokulimala kwemishini.
- I-Telecommunication Cable Protection: Isetshenziswa njengamapayipi ukuvikela izintambo zokuxhumana ezibucayi eziteshini eziyisisekelo noma amanethiwekhi e-fiber optic.
- Amathaneli namabhuloho: Afakelwe ukubeka amakhebuli ezindaweni okunzima ukuhamba kuzo noma ezifaka izimo eziyinkimbinkimbi, ezifana nezilungiselelo zokubola noma ezinomswakama ophezulu.
Ngaphezu kwalokho, i-FRP epoxy pipe (GRE) isetshenziswa kabanzi ezitshalweni zezimboni njengenqubo yamapayipi okudlulisa uketshezi lwamakhemikhali agqwala kakhulu namanzi angcolile. Ekuthuthukisweni kwendawo kawoyela, isetshenziselwa izinhlelo zokusebenza ezinokugqwala okuphezulu njengemigqa yokuqoqa uwoyela ongahluziwe, imigqa yomjovo wamanzi/ipholima, kanye nomjovo we-CO2. Ekusabalaliseni uphethiloli, iyimpahla efanelekile yamapayipi esiteshi sikaphethiloli angaphansi komhlaba namajethi asetheminali kawoyela. Ngaphezu kwalokho, kuwukukhetha okuncanyelwayo kwamanzi okupholisa amanzi olwandle, izintambo zokucisha umlilo, kanye nemigqa yokukhipha umfutho ophezulu kanye ne-brine ezitshalweni zokukhipha usawoti emanzini.
