Laupapa mamafa

Laupapa mamafa

Filifiliga o mea talafeagai mo soʻo se faʻatonuga poʻo se laina tui vailaʻau e faʻatatau i le faʻaogaina ma tulaga o nofoaga.Ina ia fesoasoani i le filifiliga, o laulau o loʻo i lalo o loʻo tuʻuina atu ai fua faʻatatau o le mamafa i totonu ma mea e faʻafetaui ai mo le tele o togi masani ma le lapopoa o paipa uʻamea leisa ma leisa.
Osi maualuga (P) mo TP 316L ile 100°F (38°C)1)
Fa'amolemole va'ai i fa'avasegaga ma fomu oloa fa'atatau i lalo.
