(1) uelo paipa mai le uamea ipu uelo i le paipa lapotopoto, vaevaeina i le maualuga taimi tetee uelo paipa (RW uelo paipa), su'isu'i sa'o arc paipa uelo (LSAW), spiral uelo paipa. Electrical inisinia ma "SC", e mafai ona faaaogaina e pei o paipa kasa vai e mafai foi ona faʻaaogaina e fai ma paipa filo, e matua mafiafia.

(2) Pipeline paipa, e lauiloa foi o le uaea paipa, e fai si manifinifi, fa'ailogaina e le "T", ma e mafai ona fa'aaogaina mo filo.

(3) ERW tube o le "maualuga taimi tetee uʻamea faagaau uʻamea", ma le faiga masani uelo e ese, o le laina uelo e mai le mea faavae o le uamea fusi tino ua liusuavai, o le malosi faainisinia e sili atu nai lo le uelo lautele.ERW tu. mo le uelo tetee, uelo tetee ei ai uiga o le maualuga o le gaosiga o le gaosiga, tau maualalo, faasaoina o meafaitino ma le masini faigofie, o lea e masani ona faʻaaogaina i vaalele, aerospace, malosi, eletise, taʻavale, alamanuia mama ma isi vaega tau alamanuia, o se tasi o le faiga uelo taua.
