Pipa Epoxy FRP
Hōʻike huahana
ʻO ka paipu epoxy FRP i kapa ʻia ʻo Glass Fiber Reinforced Epoxy (GRE) paipu. He paipu mea hoʻohuihui kiʻekiʻe, hana ʻia me ka filament winding a i ʻole kaʻina hana like, me nā fibers aniani ikaika kiʻekiʻe e like me ka mea hoʻoikaika a me ka resin epoxy e like me ka matrix. ʻO kāna mau pōmaikaʻi koʻikoʻi, ʻo ia ka pale ʻana i ka corrosion (e hoʻopau i ka pono o nā pale pale), ke kaumaha māmā i hui pū ʻia me ka ikaika kiʻekiʻe (hoʻomaʻamaʻa i ka hoʻokomo ʻana a me ka lawe ʻana), haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa (e hāʻawi ana i ka insulation thermal a me ka mālama ʻana i ka ikehu), a me ka paia i loko ʻaʻole scaling. ʻO kēia mau hiʻohiʻona he mea kūpono ia no ka paipu kuʻuna ma 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 o nā waiwai i hoʻohālikelike ʻia me nā mea kahiko:
1. Kū'ē Kū'ē Kū'ē
- ʻO ke Keʻakeʻa Kemika: Kūʻē nui ʻia i nā ʻano media corrosive, e komo pū me nā waikawa, nā alkali, nā paʻakai, nā ʻōpala, a me ka wai kai.
- Maintenance-Free: ʻAʻole koi i nā pale pale i loko a i waho a i ʻole ka pale cathodic, e hoʻopau pono i ka mālama ʻana i ka corrosion a me ka pilikia.
2. ʻO ke kaumaha māmā a me ka ikaika kiʻekiʻe
- Hoʻemi ʻia ka Density: He 1/4 a hiki i ka 1/8 wale nō ke kaumaha o ka paipu kila, e hoʻomaʻamaʻa nui i ka logistic, ka hāpai ʻana, a me ka hoʻokomo ʻana, e hoʻohaʻahaʻa i nā kumukūʻai holoʻokoʻa.
- ʻO ka ikaika o ka mīkini kiʻekiʻe: Loaʻa i ka tensile kiʻekiʻe, kūlou, a me ka ikaika hopena, hiki ke hoʻokele i nā kaomi hana kiʻekiʻe a me nā ukana o waho.
3. Nā ʻano Hydraulic maikaʻi loa
- Smooth Bore: He haʻahaʻa haʻahaʻa loa ko ka ʻili o loko, e hōʻemi nui ana i ka nalowale o ke poʻo wai a me ka puhi ʻana i ka ikehu hoʻohālikelike ʻia me nā paipu metala.
- Non-Scaling: Kū'ē ka pā maʻemaʻe i ka piliʻana o ka unahi, sediment, a me ka bio-fouling (e like me ka uluʻana o ka moana), e mālama ana i ka maikaʻi o ke kahe kiʻekiʻe i ka manawa.
4. Waiwai Thermal & Uila
- ʻO ka Insulation Thermal: Loaʻa ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa (e pili ana i 1% o ke kila), e hāʻawi ana i ka insulation maikaʻi loa e hōʻemi i ka nalowale o ka wela a i ʻole ka loaʻa ʻana o ka wai i lawe ʻia.
- ʻO ka Insulation Electrical: Hāʻawi i nā waiwai insulation uila maikaʻi loa, e palekana a kūpono hoʻi no ka hoʻohana ʻana i ka mana a me nā wahi kamaʻilio.
5. Ka lōʻihi a me ke kumu kūʻai o ke ola haʻahaʻa
- Ola Hana lōʻihi: Hoʻolālā ʻia no ke ola lawelawe o 25 mau makahiki a ʻoi aku paha ma lalo o nā kūlana hana maʻamau.
- Maintenance liʻiliʻi: Ma muli o kona ʻinoʻino a me ka pale ʻana i ka scaling, pono ʻole ka ʻōnaehana i ka mālama maʻamau, e hopena i ke kumukūʻai haʻahaʻa holoʻokoʻa.
