Donpipe 302 HCFC-141b fa'avae fa'afefiloi polyols mo le fa'aogaina o paipa
FOLASAGA
O lenei oloa o se ituaiga polyols faʻafefiloi muamua ma le HCFC-141B, lea e suʻesuʻeina faʻapitoa mo le PUF malo e gaosia ai paipa faʻafefe vevela.E faʻaaogaina lautele i paipa ausa, liquefied natura gas taʻavale paipa, paipa suauu ma isi fanua.O uiga ia e faapea:
(1) lelei le tafe, e ala i le faʻatonutonuina o fua faʻatatau e fetaui ma diameters paipa eseese.
(2) lelei le mautu o le vevela maualalo
