ASTM A320
Aotelega
Na fa'amaonia muamua i le 1948, o le ASTM A320 fa'amatalaga e aofia ai u'amea u'amea ma mea fa'apipi'i u'amea mo le auaunaga maualalo le vevela. O lenei tulaga masani e aofia ai fa'amau fa'amalo, fa'amalo, fa'amau, fa'amau, ma fa'amau fa'aoga mo va'a mamafa, valve, flanges, ma mea fa'apipi'i. E pei o le ASTM A193 faʻamatalaga, seʻi vagana ua faʻamaonia, o le 8UN thread series o loʻo faʻamaonia i luga o le faʻamau e sili atu i le 1" le lautele.
O lo'o i lalo se fa'amatalaga autu o nai togi masani i totonu ole ASTM A320 fa'amatalaga. Ole numera o isi togi e le masani ai ole ASTM A320 o lo'o iai, ae e le o aofia i le fa'amatalaga o lo'o i lalo.
