High density Polyethylene Pipe Vasega
O le vasega paipa HDPE e lautele pe bimodal tufatufaga mole mamafa.O lo'o i ai le malosi o le fetolofi ma le paleni lelei o le ma'a'a ma le ma'a'a.E matua umi ma e maualalo le sag pe a faʻagaioia.O paipa e gaosia i le faʻaaogaina o lenei resin e iai le malosi lelei, faʻamaʻi ma le aʻafiaga o le malosi ma mea sili ona lelei a le SCG ma le RCP.
O le resini e tatau ona teuina i totonu o se fale teu oloa matutu ma mamao ese mai le afi ma le susulu o le la.E le tatau ona faaputuputu i luga o le ea.I le taimi o felauaiga, o mea e le tatau ona faʻaalia i le malosi o le la poʻo le timu ma e le tatau ona feaveaʻi faʻatasi ma oneone, palapala, uamea, koale poʻo tioata.O felauaiga faʻatasi ma mea oona, pala ma mu e matua faʻasaina.
Fa'atatauga
E mafai ona faʻaaogaina le paipa HDPE i le gaosiga o paipa faʻamalosi, e pei o paipa vai faʻamalosi, paipa kesi ma isi paipa fale gaosi oloa.E mafai fo'i ona fa'aoga mo le faia o paipa e le fa'amalosi e pei o paipa fa'a'au'u puipui lua, paipa fa'ata'amilomilo puipui, paipa silicon-core, paipa fa'ato'aga fa'ato'aga ma paipa fa'apipi'i alumini.E le gata i lea, e ala i le faʻafefeteina (silane cross-linking), e mafai ona faʻaogaina mo le gaosia o paipa polyethylene (PEX) faʻafesoʻotaʻi mo le tuʻuina atu o vai malulu ma vevela.
