API 5L u'amea paipa u'amea Fa'agasologa Gaosi
Ituaiga 1. Fa'apipi'i Uila: Paipa u'amea fa'apipi'io lo'o gaosia e ala i le u'uina fa'asolosolo se fasi u'amea, e fai ai se su'iga helical. O lenei faiga e mafai ai ona gaosia paipa lapoa tetele ma e masani ona sili atu le taugofie mo nisi talosaga.
Ufiufi ma Togafitiga:Ina ia faʻaleleia atili le faʻamaʻiina ma le tumau, o nei paipa e mafai ona faʻapipiʻiina ma togafitiga eseese, e pei ole fusion bonded epoxy (FBE) poʻo le tolu-layer polyethylene (3LPE) coatings.
Ituaiga 2. Uila Fa'aeletise (ERW):O pito o le u'amea ua fausia e faʻamafanafanaina e faʻaaoga ai le eletise eletise. Ona fa'aogaina lea o le fa'amalosi e fa'apipi'i fa'atasi ai pito, ma fa'atupuina ai se uelo mautu e aunoa ma le mana'omia o mea fa'atumu.
Ituaiga 3.Uiliga Fa'aumi:
Su'ega Arc Su'e (SAW): O pito o le paipa ua faʻapipiʻiina o loʻo faʻapipiʻiina faʻatasi e faʻaaoga ai le faʻaogaina o le faʻaogaina o le arc, lea e aofia ai le faʻaogaina o le eletise eletise ma le faʻafefe faʻapipiʻi e fatu ai se maualuga maualuga, malosi.
Fa'alua Fa'asa'o Fa'asu'e (DSAW): Mo paipa mafiafia, o totonu ma fafo su'iga e uelo, fa'amautinoa le tu'i atoatoa ma le malosi.
