Paipu Epoxy FRP
Wehewehe Huahana
ʻO ka paipu epoxy FRP i kapa mua ʻia ʻo Glass Fiber Reinforced Epoxy (GRE). He paipu mea hui kiʻekiʻe ia, i hana ʻia me ka hoʻohana ʻana i kahi wili filament a i ʻole ke kaʻina hana like, me nā olonā aniani ikaika kiʻekiʻe e like me ka mea hoʻoikaika a me ka resin epoxy ma ke ʻano he matrix. ʻO kona mau pono nui e komo pū me ke kūpaʻa ʻana i ka palaho (e hoʻopau ana i ka pono no nā uhi pale), ke kaumaha māmā i hui pū ʻia me ka ikaika kiʻekiʻe (e hoʻomaʻalahi ana i ke kau ʻana a me ka lawe ʻana), ka conductivity thermal haʻahaʻa loa (e hāʻawi ana i ka insulation thermal a me ka mālama ikehu), a me kahi paia kūloko laumania, ʻaʻole scaling. ʻO kēia mau ʻano e lilo ia i pani kūpono no nā paipu kuʻuna i nā ʻāpana e like me ka petroleum, kemika, ka ʻenekinia moana, ka insulation uila, a me ka mālama wai.
Nā Hiʻohiʻona Huahana
Hāʻawi ka FRP Epoxy Pipe (Glass Fiber Reinforced Epoxy, a i ʻole GRE) i kahi hui maikaʻi loa o nā waiwai i hoʻohālikelike ʻia me nā mea kuʻuna:
1. Kū'ē Kūikawā i ka ʻAʻai
- Palekana Kemika: Kūpaʻa loa i nā ʻano mea ʻino like ʻole, me nā waikawa, alkalis, paʻakai, wai ʻino, a me ka wai kai.
- ʻAʻohe Mālama: ʻAʻole pono nā uhi pale kūloko a waho paha a i ʻole ka pale cathodic, e hoʻopau loa ana i ka mālama a me ka pilikia e pili ana i ka pala.
2. Kaumaha Māmā a me ka Ikaika Kiʻekiʻe
- Hoʻemi ʻia ka nui: ʻO ke kaumaha he 1/4 a 1/8 wale nō o ka paipu kila, e hoʻomaʻalahi nui ana i ka logistics, ka hāpai ʻana, a me ke kau ʻana, kahi e hoʻohaʻahaʻa ai i nā kumukūʻai papahana holoʻokoʻa.
- Ikaika Mechanical Kiʻekiʻe: Loaʻa i ka ikaika tensile, kulou, a me ka hopena kiʻekiʻe, hiki ke lawelawe i nā kaomi hana kiʻekiʻe a me nā ukana o waho.
3. Nā ʻano Hydraulic maikaʻi loa
- ʻŌpū Lauoho: He haʻahaʻa loa ka friction factor o ka ʻili o loko, e hōʻemi nui ana i ka pohō poʻo wai a me ka hoʻohana ʻana i ka ikehu pumping i hoʻohālikelike ʻia me nā paipu metala.
- ʻAʻole Unahi: Kūʻē ka paia laumania i ka pipili ʻana o ka unahi, ka lepo, a me ka bio-fouling (e like me ka ulu ʻana o ke kai), e mālama ana i ka pono o ke kahe ʻana i ka hala ʻana o ka manawa.
4. Nā Waiwai Wela a me ka Uila
- Palena Wela: He haʻahaʻa loa ka conductivity thermal (ma kahi o 1% o ke kila), e hāʻawi ana i ka pale maikaʻi loa e hōʻemi i ka nalowale a i ʻole ka loaʻa ʻana o ka wela no ka wai i lawe ʻia.
- ʻO ka pale uila: Hāʻawi i nā waiwai pale uila maikaʻi loa, e palekana ai a kūpono hoʻi no ka hoʻohana ʻana i nā wahi mana a me ke kamaʻilio ʻana.
5. Ka Paʻa a me ke Kumukūʻai Haʻahaʻa o ke Kaʻapuni Ola
- Ola Hana Lōʻihi: Hoʻolālā ʻia no kahi ola hana o 25 mau makahiki a ʻoi aku paha ma lalo o nā kūlana hana maʻamau.
- Mālama Liʻiliʻi Loa: Ma muli o kona kūpaʻa i ka pala a me ka unahi ʻana, ʻaʻole pono ka ʻōnaehana i ka mālama maʻamau, e hopena ana i ka uku haʻahaʻa o ke ola holoʻokoʻa.

Nā Hoʻohana Huahana
- Nā Laina Hoʻoili Uila Kiʻekiʻe: Hoʻohana ʻia ma ke ʻano he mau paipu pale no nā kaula mana uila kiʻekiʻe ma lalo o ka honua a i ʻole ma lalo o ka wai.
- Nā Hale Mana / Nā Kahua Hoʻololi Mana: Hoʻohana ʻia e pale i nā kaula mana a me nā kaula kaohi i loko o ke kahua mai ka palaho o ke kaiapuni a me ka pōʻino mechanical.
- Ka Palekana o ke Kaula Kelepona: Hoʻohana ʻia e like me nā ducts e pale aku i nā kaula kamaʻilio koʻikoʻi ma nā kahua kumu a i ʻole nā pūnaewele fiber optic.
- Nā Tunnels a me nā Alahaka: Hoʻokomo ʻia no ke kau ʻana i nā kaula i nā wahi paʻakikī ke hoʻokele a i ʻole nā kūlana paʻakikī, e like me nā hoʻonohonoho ʻino a kiʻekiʻe paha ka makū.
Eia kekahi, hoʻohana nui ʻia ka paipu epoxy FRP (GRE) i nā hale hana ʻoihana ma ke ʻano he paipu hana no ka lawe ʻana i nā wai kemika ʻino loa a me ka wai hoʻoneoneo. I ka hoʻomohala ʻana i ke kahua ʻaila, hoʻohana ʻia ia no nā noi ʻino kiʻekiʻe e like me nā laina hōʻiliʻili ʻaila maka, nā laina injection wai/polymer, a me ka injection CO2. I ka hoʻolaha wahie, ʻo ia ka mea kūpono no nā paipu kikowaena kinoea ma lalo o ka honua a me nā jetties terminal aila. Eia kekahi, ʻo ia ke koho makemake ʻia no ka wai hoʻoluʻu wai kai, nā laina hoʻopau ahi, a me nā laina hoʻokuʻu kiʻekiʻe a me ka brine i nā hale hana desalination.
