Va'aiga lautele o Paipa Umea
Ua silia ma le 70 tausaga talu ona maua le paipa u'amea ductile i le 1940s. Faatasi ai ma lona malosi maualuga, elongation maualuga, corrosion teteʻe, tetee atu i le faateʻia, faigofie fausiaina ma le tele o isi foliga lelei, ductile uʻamea paipa o le filifiliga sili lea i le lalolagi i aso nei mo le feaveaiina o le vai ma le kesi saogalemu. O le u'amea u'amea, e ta'ua foi o le u'amea nodular po'o le u'amea spheroidal graphite, o lo'o fa'aalia e ala i le i ai o le graphite spheroidal i mea e maua mai ai.

Fa'aogaina o le Umea
O le u'amea fa'atosina e sili atu le malosi ma le fa'amamago nai lo le u'amea efuefu. O na meatotino e mafai ai ona faʻaoga lelei i le tele o ituaiga o mea tau alamanuia, e aofia ai paipa, mea tau taʻavale, uili, pusa faʻapipiʻi, fale pamu, faʻavaa masini mo le gaosiga o le matagi, ma le tele o isi mea. Talu ai e le gau e pei o le u'amea efuefu, e saogalemu fo'i le fa'aogaina o le u'amea ductile e fa'aoga i mea e puipuia ai a'afiaga, e pei o pou.
