API 5L:O lenei tulaga o loʻo faʻatulagaina e le American Petroleum Institute ma faʻamaoti mai manaʻoga mo le gaosiga o paipa laina faʻaaogaina mo le faʻaaogaina o suauu, kesi, ma isi oloa faʻavae suauʻu. O le tausisia o le API 5L e faʻamautinoa ai o le paipa uʻamea LSAW e fetaui ma tulaga lelei ma faʻatinoga mo le faʻaaogaina i le suauʻu ma le kesi.
ASTM A53:ASTM A53 o se faʻamatalaga masani mo paipa, uʻamea, uliuli ma vevela, faʻafefeteina, faʻapipiʻi, ma le faʻaogaina. O le tausisia o le ASTM A53 e faʻamautinoa ai o le paipa uʻamea LSAW e fetaui ma manaʻoga faʻapitoa mo le faʻaogaina i masini ma faʻaoga faʻamalosi, faʻapea foʻi ma le faʻaogaina lautele.
ASTM A252:o se faʻamatalaga masani mo faʻaputu uʻamea uʻamea ma seamless paipa. A o'o mai ile LSAW (Longitudinal Submerged Arc Welded) paipa u'amea, o le usita'ia o le ASTM A252 e sili ona talafeagai mo talosaga e aofia ai fa'aputu u'amea fa'aoga i galuega faufale ma galuega lagolago. ASTM A252 o loʻo faʻamaoti mai manaʻoga faʻapitoa mo paipa paipa uʻamea, e aofia ai fua, mea faʻainisinia, ma faʻataʻitaʻiga suʻega.
LSAW paipa uʻamea e ogatasi ma ASTM A252 ua mamanuina e faʻamalieina manaʻoga faʻapitoa mo le faʻaogaina i faʻaputuga talosaga, e pei o le fausiaina o faavae, fausaga o le gataifale, fausiaina o alalaupapa, ma isi galuega faʻainisinia. O le tausisia o le ASTM A252 e faʻamautinoa ai o paipa uʻamea LSAW e fetaui lelei ma tulaga talafeagai, faʻatinoga, ma tulaga saogalemu mo le faʻaogaina i le faʻaputuina o talosaga.
