Suau'u asphalt, mea mata lautele, tau maualalo.Ae ui i lea, le lelei o tulaga faigaluega, faigata ona faʻamautinoa le lelei, faʻaleagaina le siosiomaga.

Epoxy tar koale, faigofie ona faagaoioia, ae o se taimi umi e ufiufi ai le vaega e fofoina i aafiaga o le siosiomaga, talafeagai mo galuega i le fanua, o le 10 ℃ faigata o loʻo mulimuli mai.

Anticorrosive malulu lipine, faigofie ona faagaoioia, ae sili atu le leaga adhesion, maualalo vai tetee, maualalo le malosi, le tele aafiaga siosiomaga.

Epoxy pa'u pala, electrostatic spraying, anti-corrosion mea ma le ituaiga tutusa o paipa frit lelei, sootaga malosi, epoxy pa'u ae vaivai le vai (maualuga vai absorption, e oo atu i le 0.83%), i le cathodic puipuiga mamanu aumaia nisi faigata.Manaoga meafaigaluega nofoaga, o le taotoga e faigata, faigata ona pulea lelei.

3PE faʻaitiitia mea, faʻamaufaʻailogaina malosi paipa paipa, malosi faʻainisinia maualuga, malosi faʻafefe vai, tulaga mautu, faʻaoga faigofie, faʻaoga, ma e le faʻaleagaina le siosiomaga.PE maualalo vai absorption (itiiti ifo i le 0.01%), faʻatasi ai ma le epoxy malosi maualuga, faʻafefe faʻafefete faʻafefe PE maualalo vai absorption ma lelei fetuutuunai, faʻatuatuaina maualuga corrosion, o le le lelei o le: Pe a faatusatusa i isi mea toe faaleleia tau maualuga tau.

Fa'aaliga malulu lipine ma 3PE fa'aitiiti fusi o: mo ituaiga uma o mea e ufiufi paipa o le tino, ae o le isi auala e fa'atatau i le tutusa po'o le latalata i le paipa mea fa'apipi'i tino.
