vili Collars
O le kola vili e avea o se tasi o vaega o le manoa vili e matua'i fa'aoga tubula fa'aaogā e vili ai i totonu o le 'ele'ele e maua ai le mamafa mo le viliina.E fa'aoga e fa'atasi ma paipa vili.O lo'o i ai ituaiga maseesee ma fa'ata'amilomilo fa'atele.O la matou gaosiga fa'agasologa ua fa'amaonia i le API fa'apitoa 7-1.O le kola vili e faia i le AISI 4145 H poʻo le 4145 H Modified alloy steel.E fa'asolo mai le tasi itu e aunoa ma se fetaui.O kola vili uma e fa'afefeteina i le ma'a'a i totonu ole 285 i le 341 BHN, lea e fa'amaonia le tasi inisi i lalo ole pito i luga ole paipa.
O kola vili e le fa'amaneta e maua ai le malosi ma le ma'a'a a'o puipuia le fa'alavelave fa'amaneta e ono fa'aleagaina ai le sa'o o su'esu'ega fa'amaneta.O lo'o gaosia mai mea fa'apitoa u'amea fa'atasi ma le maualalo o le pa'u, mea fa'ainisinia maualuga ma le maualuga o le tete'e atu i le fa'a'a'a'a.
Matou te tu'uina atu kola vili masi, kola vili li'o ma kola vili e le fa'amaneta;o latou lapopoa e mai le 3-1 / 8 i le 11 inisi.E ese mai i kola vili i le laulau o lo'o i lalo, e mafai ona matou tu'uina atu isi kola vili i talosaga a tagata fa'atau.
