Fusion-Bonded Epoxy Coatings and Lains for Steel Water Paipa ma mea fa'apipi'i

Ole tulaga lea ole American Water Works Association(AWWA).FBE coatings e masani ona faʻaaogaina i luga o paipa vai uʻamea ma mea faʻapipiʻi, mo se faʻataʻitaʻiga o paipa SSAW, paipa ERW, paipa LSAW paipa faʻafefe, tulilima, tees, reducers ma isi mo le faʻamoemoe o le puipuiga o le pala.

Fusion-bonded epoxy coatings o se tasi vaega faʻamago-pauta thermosetting coatings e, pe a faʻagaoioia le vevela, e maua ai se faʻamaʻi faʻamaʻi i luga o le paipa uʻamea aʻo faʻatumauina le faʻatinoga o ona meatotino.Talu mai le 1960 i luga, ua fa'alauteleina le fa'aoga i paipa lapopoa e pei o totonu ma fafo e ufiufi mo le kesi, suauu, vai ma vai otaota.

1. Porosity cross-section.
2. Fa'asagaga porosity.
3. Su'esu'ega vevela (DSC).
4. Fa'agata tumau (ga'o).
5. Suavai vai.
6. Aafiaga.
7. Su'ega fa'amavaega o le Cathodic.
