FRP Epoxy paipa
Fa'amatalaga o oloa
FRP epoxy paipa ua lauiloa aloaia o Glass Fiber Reinforced Epoxy (GRE) paipa. O se paipa mea faʻapipiʻi maualuga, gaosia e faʻaaoga ai se filament winding poʻo se faiga faʻapena, faʻatasi ai ma alava tioata malosi maualuga e avea ma mea faʻamalosia ma epoxy resin e pei o le matrix. O ona fa'amanuiaga autu e aofia ai le mataʻina o le faʻafefeteina (faʻaitiitia le manaʻomia mo ufiufi puipui), mama mama tuʻufaʻatasia ma le malosi maualuga (faʻafaigofieina le faʻapipiʻiina ma felauaiga), faʻaogaina le vevela tele (tuuina atu le vevela vevela ma le faʻasaoina o le malosi), ma se puipui lamolemole, e le faʻafefe i totonu. O nei uiga lelei e fai ma sui lelei mo paipa masani i vaega e pei o le suauu, vailaʻau, inisinia o le gataifale, faʻapipiʻi eletise, ma togafitiga vai.
Oloa Fa'ailoga
O le FRP Epoxy Pipe (Glass Fiber Reinforced Epoxy, poʻo le GRE) e ofoina atu se tuʻufaʻatasiga sili atu o meatotino pe a faʻatusatusa i mea masani:
1. O mea e sili ona leaga
- Fa'ama'i Fa'ama'i: E sili ona fa'asalaina i le tele o ala fa'a'ala'au, e aofia ai acids, alkalis, masima, otaota, ma le sami.
- Tausiga-Sa'oloto: E le mana'omia ni ufiufi puipui i totonu po'o fafo po'o se puipuiga cathodic, fa'amautu le fa'aitiitia o le fa'aleleia ma le lamatiaga.
2. Mamafa Mama ma Malosi Maualuga
- Fa'aiti'itia Density: E na'o le 1/4 i le 1/8 le mamafa o le paipa u'amea, fa'afaigofie tele le fa'aogaina, si'itia, ma le fa'apipi'iina, lea e fa'aitiitia ai le tau atoa o galuega.
- Malosi Fa'ainisinia Sili: O lo'o i ai le maualuga maualuga, punou, ma le malosi o le a'afiaga, e mafai ona fa'atautaia le maualuga o le fa'agaoioiga mamafa ma uta i fafo.
3. Uiga Sili Hydraulic
- Smooth Bore: O le pito i totonu o loʻo i ai se mea e matua maualalo le feteʻenaʻi, e faʻaitiitia ai le sua o le ulu ma pamu le malosi faʻatusatusa i paipa uʻamea.
- Non-Scaling: O le puipui lamolemole e tetee atu i le pipii i le fua, palapala, ma le bio-fouling (e pei o le tuputupu ae o le gataifale), faatumauina le maualuga o le tafe i le taimi.
4. Meatotino vevela & Eletise
- Insulation Thermal: O lo'o fa'aalia ai le fa'aogaina o le vevela (e tusa ma le 1% o le sila), e maua ai le fa'amalo lelei e fa'aitiitia ai le vevela po'o le maua o le sua.
- Insulation Fa'aeletise: E ofoina atu mea e sili atu le fa'aogaina o le eletise, e saogalemu ma talafeagai mo le fa'aoga i le eletise ma feso'ota'iga si'osi'omaga.
5. Maumau ma Tau Maualalo o le Taamilosaga o le Ola
- Umi Auaunaga Ola: Fuafuaina mo se soifua tautua o le 25 tausaga pe sili atu i lalo o tulaga masani faagaoioia.
- Tausiga La'ititi: Ona o lona pala ma le fa'asa'oina o le malosi, e le mana'omia e le faiga le tausiga masani, e mafua ai le maualalo o le tau atoa o le olaga.
