O nei tulaga, e aofia uma i tulaga uamea a Amerika, e pei o le ASME i mea o loʻo faʻaaogaina e tulaga faʻataʻitaʻiga e mai le ASTM, o le valve i le API faʻamatalaga masani, ma paipa uʻamea vaivai mai le tulaga ANSI.O le eseesega o loʻo taoto i le eseʻese o le taulaiga o le alamanuia, o lea la o le vaetamaina o tulaga eseese.API, ASTM, ASME o sui o le ANSI.American National Standards Institute, o le tele lava mai tulaga fa'apolofesa.I le isi itu, o faʻalapotopotoga faʻapolofesa, faʻalapotopotoga, faʻalapotopotoga e mafai foi ona faʻavae i luga o tulaga faʻale-malo o loʻo iai e atiaʻe ai tulaga faʻapitoa o oloa.Ioe, e le mafai ona mulimulitaʻia tulaga faʻale-atunuu e atiaʻe ai a latou lava tulaga faʻalapotopotoga.O fa'amaumauga a le ANSI e fai fua.E talitonu le Iunaite Setete o tulaga fa'atulafonoina e mafai ona fa'atapula'a ai tupe maua.Ae e tusa ai ma le tulafono ma matagaluega a le malo e atiaʻe tulaga, e masani lava o se tulaga faʻatulafonoina.
