FRP Flange
Fa'amatalaga o oloa
FRP (Fiberglass Reinforced Plastic) flanges o fesoʻotaʻiga foliga mama e faʻaoga e faʻapipiʻi ai paipa, valve, pamu, poʻo isi meafaigaluega e fausia ai se paipa atoatoa. E faia mai se mea tu'ufa'atasi e aofia ai alava tioata e fai ma mea fa'amalosia ma resini fa'asusu e pei o le matrix. O lo'o gaosia i le fa'aogaina o faiga e pei o le fa'aliliina, fa'apipi'i lima, po'o le fa'a'alili o filament.
Oloa Fa'ailoga
Fa'afetai i lo latou tu'ufa'atasiga tu'ufa'atasi, FRP flanges e ofoina atu le tele o fa'amanuiaga i luga o fa'ailoga u'amea masani:
- Fa'asao Lelei: O le mea e sili ona mata'ina o le FRP flanges o lo latou gafatia e tetee atu i le pala mai fa'asalalauga fa'a-kemikolo eseese, e aofia ai acids, alkalis, salts, ma solvents organic. O le mea lea e fa'aaogaina lautele ai i totonu o si'osi'omaga o lo'o feavea'i ai sua fa'ama'i, e pei o vaila'au, suau'u, metallurgy, eletise, vaila'au ma mea'ai.
- Mama ma Malosi Maualuga: O le mamafa o le FRP e masani lava naʻo le 1/4 i le 1/5 o le sila, ae o lona malosi e mafai ona faʻatusatusa. O le mea lea e faigofie ai ona latou felauaiga ma faʻapipiʻi, ma faʻaitiitia ai le mamafa atoa o le paipa.
- Fa'agata Eletise Lelei: FRP o se mea e le fa'aaogaina, e tu'uina atu ai le FRP flanges e sili ona lelei le fa'aogaina o le eletise. E taua tele lenei mea i siosiomaga faʻapitoa e puipuia ai le pala eletise.
- Fuafuaga Maualuga Maualuga: E ala i le fetuunaiga o le resin formula ma le faʻatulagaina o filo tioata, FRP flanges e mafai ona faia faʻapitoa e faʻafetaui ai manaʻoga faʻapitoa mo le vevela, mamafa, ma le faʻafefeteina.
- Tau Tausia maualalo: FRP flanges e le elea pe fua, e oʻo atu ai i le umi o le auaunaga ma faʻaitiitia ai tau tausiga ma toe sui.
Ituaiga Oloa
Faʻavae i luga o la latou gaosiga faʻagasologa ma le faʻatulagaina, e mafai ona faʻavasegaina flanges FRP i ni ituaiga:
- Tasi-Piece (Integral) Flange: O lenei ituaiga ua faia o se iunite e tasi ma le tino paipa, e ofoina atu se fausaga fufusi talafeagai mo talosaga maualalo i le feololo.
- Ta'a'alo Fa'amama (Lap Joint Flange): E iai se mama fu'a matala ma se fa'au'au mau i le paipa. O lenei mamanu faʻafaigofie le faʻapipiʻiina, aemaise lava i fesoʻotaʻiga tele-point.
- Flange Tauaso (Flage Avanoa/Ipu Fa'ai'u): Fa'aaogā e fa'amau ai le pito o se paipa, e masani lava mo le su'esu'eina o faiga o paipa po'o le fa'aagaga o se atina'e.
- Socket Flange: O le paipa e faʻapipiʻi i totonu o le pito i totonu o le flange ma faʻafesoʻotaʻi lelei e ala i faʻapipiʻi pipii poʻo faiga faʻafefe, faʻamautinoa lelei le faʻamaufaʻailogaina.

Talosaga Oloa
Ona o le tulaga ese o latou tetee ma le malosi mama, FRP flanges e masani ona faʻaaogaina i:
- Alamanuia Kemisi: Mo paipa felauaiga vaila'au pala e pei o acids, alkalis, ma masima.
- Inisinia Siosiomaga: I le fa'amamaina o le suavai otaota ma le fa'amama kasa fa'ameamea.
- Alamanuia Malosiaga: Mo vai malulu ma desulfurization / denitrification faiga i fale eletise.
- Inisinia o le Gataifale: I le faamamaina o le sami ma faiga paipa o vaa.
- Mea'ai ma Fale Talavai: Mo laina gaosiga e mana'omia ai le mama maualuga.
