Pipa u'amea u'amea u'amea, e ta'ua fo'i o le fa'a'au'au u'amea u'amea u'amea, ose pa'u'ō'o umi e fa'aaogaina mo le fe'avea'i vai (suavai po'o kasa).
“Papa u'amea lamolemole” ma le “paipa u'amea” e toetoe a mafai ona fesuia'i, e ui lava e iai ni eseesega laiti-e masani lava, o se paipa e sili atu ona malosi mana'oga inisinia nai lo se paipa.
O Cepheus o se tagata gaosi tomai faapitoa i le gaosiga o paipa e leai ni mea i totonu o lapopoa, feololo, ma laiti.
Eseese uamea u'amea seamless paipa e gaosia ma fa'amatalaga atoatoa ma tulaga maualuga.
Cepheus ei ai meafaigaluega lelei ma atoatoa pulega lelei, faʻatūina faiga faʻaonaponei pulega lelei, faʻalauiloaina tekinolosi faʻavaomalo faʻavaomalo ma faʻaaogaina metotia faʻavaomalo faʻavaomalo.
O paipa fa'alelei uamea e masani ona fa'aaogaina i ia alamanuia e pei o le suau'u, alamanuia vaila'au, masini, eletise eletise, alava vaila'au, fai pepa, lolomi ma vali, mea'ai ma vaega pneumatic ma isi.
O loʻo tuʻuina atu e le kamupani masini suʻesuʻe atoatoa ma faʻaaogaina tulaga faʻapitoa mo oloa e pei o: paipa faʻafefe mo le felauaiga o le vai, paipa faʻafefe mo le fausiaina, faʻaogaina mo le faʻavela ma le vevela.
O le lautele pito i fafo o le u'amea e leai se mea matou te gaosia mai le 4.0mm i le 1219mm. O le mafiafia o le puipui e 0.5mm i le 100mm. Mo uʻamea, matou te ogaoga.
