Faatasi ai ma a tatou tekinolosi taʻutaʻua ma lo tatou agaga o le faʻafouina, felagolagomaʻi, faʻamanuiaga ma le tuputupu aʻe, o le a tatou fausia se lumanaʻi manuia faʻatasi ma lau paipa uʻamea faʻapitoa na faʻauluina, Matou te tausisia taimi faʻatulagaina taimi, mamanu fou, tulaga maualuga ma le manino mo a tatou tagata fa'atau. O la tatou moto e tatau ona tuʻuina atu oloa lelei i totonu ole taimi faʻatulagaina.
Faʻafeiloaʻi e asiasi i la matou kamupani, falegaosimea ma le matou fale teu oloa lea e faʻaalia ai a matou faʻasoa e fetaui ma lou faʻamoemoega. I le taimi nei, e faigofie ona asiasi i la matou 'upega tafaʻilagi, ma o le a taumafai le aufaigaluega faʻatau i le mea sili latou te mafaia e tuʻuina atu ia te oe le auaunaga sili. Ia mautinoa e te fa'afeso'ota'i matou pe a e mana'omia nisi fa'amatalaga. O la matou fa'amoemoe o le fesoasoani lea i tagata fa'atau ia iloa a latou sini. O loʻo matou faia ni taumafaiga sili e ausia lenei tulaga manumalo-manumalo.

E uiga i paipa uʻamea uʻamea carbon, o loʻo i ai se ituaiga poeple e taʻua o le paipa MS, o lona uiga o paipa e faia mai le uamea vaivai/maualalo uamea (carbon steel e maualalo ifo i le 0.25%). O lenei ituaiga paipa e sili ona taatele, e masani ona faʻaaogaina i le fausaga faufale, faʻailoga ma isi. O lenei ituaiga paipa e matua vaivai lava, e le mafai ona gafatia tele le malosi ma le mamafa, e mafai foi ona faʻaaogaina i le maualalo o le mamafa o felauaiga vai. Ona o lenei ituaiga uamea o loʻo i ai se mea faʻainisinia maualalo, o le a le faʻaaogaina i lefa'aoga fa'aaliga e maualuga le mana'oga, o lea pe a ta'ua e tagata le paipa MS, o lona uiga o paipa uelo.

Fa'atatauga

E masani ona faʻaaogaina mo vaega malosi ma mamafa, ma mo le faʻamoemoe lautele ausa, vai, kesi ma paipa ea.
