ua vaevaeina tau paipa u'amea i le vevela-lifu u'amea paipa u'amea ma mua'i u'amea paipa u'amea i luga o luga.Galvanizing e mafai ona faʻateleina le faʻafefe o le paipa uʻamea ma faʻaumiumi ai le ola tautua o le paipa uʻamea.
Eseesega i le va o le "Pre-galvanized paipa" ma le "Hot-dipped galvanized paipa".
1.Pre-galvanized mea faavae paipa uamea o fusi uamea uʻamea, o le auala faʻapitoa o ERW longitudinal uelo.
2.Hot-fufu u'amea faavae paipa mea o le paipa u'amea uliuli (leai se togafitiga i luga), ona vevela lea i totonu o le vaitaele zinc e maua ai le paipa.

O paipa galvanized e fa'aaogaina lautele .I le faaopoopo atu i paipa laina mo le felauaiga o le vai, afi afi, kesi, alavai, ma isi suavai maualalo maualalo, o loʻo faʻaaogaina foi e fai ma paipa lagolago i fale suauʻu, trestle piles, ma mine tunnels.
1. General afifi: i le fusi naʻo, leai se isi afifi, leai se ufiufi palasitika, leai ni fusi nailon.
2. Sea-worth package: i fusi, nonoa i fusi uamea, ufiufi palasitika anti-vai, fusi nailon pito taʻitasi o fusi.
FAQ
Q: E mafai faapefea ona ou maua se tau saʻo mo laʻu suʻesuʻega?
A: Lau pele / Madam, matou te manaʻomia lalo ifo o lou manaʻoga e siaki le tau:
1. Diamita
2. Mafiafia puipui
3. Umi
Q: O le a le ituaiga afifi o le a ou mauaina?
A: E te mauaina le afifi lautele-fa'apipi'i i fusi fa'atasi ma fusi u'amea (leai se isi ufiufi i luga) pe a fai e leai se mana'oga a le tagata fa'atau.
Q: O le a le ituaiga afifi o loʻo ia te oe?
A: 1. afifi lautele.--Tu'u i fusi ma fusi uamea, leai se isi ufiufi, leai se pusa palasitika.
2. afifi lelei.--Tu'u i fusi, ma ufiufi i pusa palasitika.
Q: E iai sau fa'asoa?
A: Ioe, e iai a matou paipa faʻapipiʻi mo faʻamatalaga lautele.
Q: E te tuʻuina atu faʻataʻitaʻiga saoloto?
A: Ioe, faʻataʻitaʻiga e leai se totogi.
A'o fa'amolemole fa'ailoa mai o le tau o fe'au fa'ava-o-malo e le'o maua fua.
E mafai ona matou toe faafoi atu le tau o le avefeau i tagata faatau pe a matou galulue faatasi.
Fa'ata'ita'i e lafo e le fe'au va'alele pe a itiiti ifo i le 1kg le mamafa.
