Le atinaʻeina o paipa uamea tekinolosi gaosiga na amata i le tulaʻi mai o pisinisi gaosi uila, o le atinaʻeina o suauʻu i le amataga o le 19 seneturi, o le gaosiga o vaʻa, faʻafu ma vaalele i le taimi o taua e lua a le lalolagi, o le gaosiga o afi eletise eletise ina ua maeʻa le Taua Lona Lua a le Lalolagi, le atinaʻeina o alamanuia kemikolo ma le viliina, gaosiga ma le felauaiga o suauu ma kesi faalenatura, o nei mea uma na matua siitia le ituaiga, gaosiga ma le lelei o alamanuia paipa uamea Atinae i luga. O paipa uʻamea e le gata e faʻaaogaina e felauaiga ai le vai ma le paʻu paʻu, fesuiaʻi le malosi o le vevela, gaosia vaega masini ma koneteina, ae faʻapea foʻi ma se uʻamea tau tamaoaiga. E mafai ona faʻaitiitia le mamafa, faʻapolopolo 20-40% uʻamea ma iloa le fale gaosi masini. O le faia o alalaupapa alalaupapa ma paipa uʻamea e le gata e mafai ona faʻasaoina le uamea ma faʻafaigofie le fausiaina, ae faʻaitiitia ai foi le vaega o le ufiufi puipui ma faʻasaoina tau o tupe teufaafaigaluega ma tausiga. E tusa ai ma le faiga o le gaosiga, e mafai ona vaevaeina le paipa uamea i ni vaega se lua: paipa uamea seamless ma paipa uamea seamed. O le paipa u'amea su'isu'i ua ta'ua sa'o su'isu'i paipa u'amea mo pu'upu'u. E mafai ona vaevaeina le paipa uamea i paipa uamea carbon, paipa u'amea ma paipa uamea stainless e tusa ai ma meafaitino (ie ituaiga uamea). e mafai ona vaevaeina paipa uamea carbon i masani paipa uamea carbon ma paipa uamea sili ona lelei. Paipa Uamea Alloy e mafai ona vaevaeina i: paipa u'amea maualalo, paipa fausaga u'amea, paipa u'amea maualuga, paipa malosi maualuga. Pipa fa'apipi'i, paipa fa'afefete le vevela ma le ga'o, u'amea sa'o (e pei o le kovar alloy) paipa ma le maualuga o le vevela o le paipa, ma isi.
