Malosi o le tetee i le malepelepe i le maualuga o le vevela ma le maualuga o le mamafa.
E mafai ona fa'aoga mo Au'aunaga Fa'a'ele'ele Hydrogen Sulfide.
Tetee i le ta'e mai le hydrogen osofaiga ma le embrittlement.
Tetee i le vevela sulfide corrosion ta'e.
E mafai ona fa'aoga mo Talosaga NACE o lo'o iai si'osi'omaga oona i lalo ole vevela ma le mamafa.
E mafai ona fa'aoga ile NACE-MRO 175 Sour Service.
Lelei mo talosaga fetolofi rupture.
E mafai ona taulimaina le maualuga o le vevela ma le maualalo tele.
O ituaiga u'amea u'amea o lo'o ufiufi e le ASTM A335 - ASME SA335 fa'amatalaga ua mamanuina i le "P" prefix, mai le P5 i le P92.Vasega P11/P22 ma le P91/92 e masani ona maua i nofoaga eletise, ae o le vasega P5 ma le P9 e sili atu ona taatele mo le faʻaogaina i totonu o fale gaosi oloa.Vasega P9, P91 o loʻo i totonu o le lisi, e sili atu le taugata
