Fa'amatalaga o le gaosiga:
O paipa fa'apipi'i ua fa'amalosia i uaea u'amea o se paipa fa'apipi'i palasitika ua fa'aleleia atili. O lenei ituaiga paipa e ta'ua fo'i o le paipa SRTP. O lenei ituaiga paipa fou e faia mai le malosi tele e ala i le fa'ata'ita'iga o uaea u'amea ma le polyethylene thermoplastic o mea mata, o le upega u'amea e pei ona fa'amalosia i le paipa palasitika polyethylene, polyethylene maualuga le mafiafia (HDPE) asmatrix, fa'atasi ai ma le fa'atinoga maualuga o le HDPE modified bonding resin o le fa'avaa u'amea ma le vaega i totonu ma fafo o le polyethylene maualuga le mafiafia e vavalalata fa'atasi, ina ia maua ai se aafiaga lelei tele o le fa'apipi'i. O le paipa fa'apipi'i e faatoilaloina ai fa'aletonu o le u'amea ma le palasitika, ae fa'atumauina pea fa'amanuiaga o ia mea uma e lua, aua o le fa'amalosi u'amea malosi tele e afifiina i totonu o se thermoplastic faifai pea.
O paipa fa'apipi'i ua fa'amalosia i uaea u'amea, e fa'aaogaina mea e sili ona lelei ma tekinolosi gaosiga fa'aonaponei, ina ia sili atu lona malosi i le mamafa. I le taimi lava e tasi, o le paipa fa'apipi'i e matua'i fetu'una'i lava, e talafeagai mo le sapalai o le vai i le tanuga mamao ma le faiga o paipa kesi. O le paipa eletise polyethylene e fa'aaogaina mo paipa fa'apipi'i polyethylene ua fa'amalosia i uaea u'amea. A fa'apipi'i, o le tino fa'avevela i totonu o le paipa e fa'aaoga e fa'amalulu ai le palasitika i fafo o le paipa ma le palasitika i totonu o le paipa, ina ia fa'afeso'ota'i fa'atasi ma le fa'atuatuaina le paipa ma le paipa.
