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 vaega e fofoina e 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 o aafiaga siosiomaga.

Epoxy efuefu pala, electrostatic spraying, anti-corrosion mea ma le ituaiga tutusa o paipa frit lelei, sooga malosi, epoxy paʻu ae vaivai le vai (maualuga vai absorption, oʻo 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, faʻafefete faʻafefete faʻafefe PE maualalo vai absorption ma lelei fetuutuunai, maualuga corrosion faatuatuaina, o le faaletonu o le: Pe a faatusatusa i isi mea toe faaleleia tau maualuga tau.

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