O paipa u'amea lamolemole e fa'aaogaina lautele
1. O paipa uʻamea faʻaogaina lautele o loʻo taʻavale e masani masani carbon structural steel, low-alloy structural steel or alloy structural steel, faʻatasi ai ma le tele o mea e gaosia, ma e masani ona faʻaaogaina e pei o paipa poʻo vaega faʻavae mo le felauaiga o vai.
2. E tusa ai ma faʻamoemoega eseese, e mafai ona tuʻuina atu i ni vaega se tolu:
a. Tuuina atu e tusa ai ma le tuufaatasiga o vailaʻau ma mea faʻainisinia;
e. E tusa ai ma le faatinoga o masini;
i. E tusa ai ma le sapalai o le suʻega o le vai. O paipa u'amea e fa'atatau i vaega a ma le b. afai e faʻaaogaina e faʻafefe ai le mamafa o le suavai, e tatau foi ona faia se suʻega hydraulic.
