API 5L:O lenei tulaga faatonuina ua faatulagaina e le American Petroleum Institute ma faamaoti mai ai manaoga mo le gaosiga o paipa laina e faaaoga mo le felauaiga o le suauu, kesi, ma isi oloa e faavae i le suauu. O le tausisia o le API 5L e faamautinoa ai o le paipa u'amea LSAW e ausia tulaga manaomia o le lelei ma le faatinoga mo le faaaogaina i le alamanuia o le suauu ma le kesi.
ASTM A53:O le ASTM A53 o se fa'amatalaga masani mo paipa, u'amea, uliuli ma le u'amea vevela, ufi i le zinc, fa'apipi'i, ma e leai ni so'oga. O le tausisia o le ASTM A53 e fa'amautinoa ai o le paipa u'amea LSAW e ausia mana'oga fa'apitoa mo le fa'aaogaina i galuega fa'amekanika ma le mamafa, fa'apea fo'i ma le fa'aaogaina lautele.
ASTM A252:o se faʻamatalaga masani mo paipa uʻamea ua ueloina ma ua leai ni soʻoga. Pe a oʻo mai i paipa uʻamea LSAW (Longitudinal Submerged Arc Welded), o le tausisia o le ASTM A252 e matua talafeagai lava mo faʻaoga e aofia ai paipa uʻamea e faʻaaogaina i galuega faufale ma galuega lagolago fausaga. O loʻo faʻamaoti mai e le ASTM A252 manaʻoga faʻapitoa mo paipa uʻamea, e aofia ai fua, meatotino faʻainisinia, ma faiga faʻataʻitaʻi.
O paipa u'amea LSAW e tausisia le ASTM A252 ua mamanuina e fa'afetaui ai mana'oga fa'apitoa mo le fa'aaogaina i galuega fa'apipi'i pou, e pei o le fausiaina o fa'avae, fausaga o le sami, fausiaina o alalaupapa, ma isi galuega fa'ainisinia sivili. O le tausisia o le ASTM A252 e fa'amautinoa ai o paipa u'amea LSAW e ausia tulaga fa'atonuina o le lelei, fa'atinoga, ma le saogalemu mo lo latou fa'aaogaina fa'amoemoeina i galuega fa'apipi'i pou.
