O lea se mea tele e lelei lava e tatau i galuega e faʻamanino ai lea i le vaega tele. E lena le tausagi mo le ala faʻatupuina o lea ua faʻamafai i ai lea e fesoasoani ai lea i le ala faʻatupuina ma le galuega o le upega selo faʻamafanui

O le upega selo faʻamafanui e tatau i le vaveaga i mea a le lauiloa, o se mea e feiai ai moe e tuu ai i le vaega tele. O lea se mea tele e lelei lava e tatau i galuega e faʻamanino ai lea i le vaega tele. E lena le tausagi mo le ala faʻatupuina o lea ua faʻamafai i ai lea e fesoasoani ai lea i le ala faʻatupuina ma le galuega o le upega selo faʻamafanui:

Faʻamanino ma faʻatupuaga lelei: O le uga spiral steel e ao i lea e lelei o niu moega, ifo ai X70 ma X80. E tutusa lea ni mea e faʻamanino lelei ma faʻatupuaga lelei, ma e tatau ona faiaoga i le stress i lo o se faiga pa faʻamanino itamea.

Faʻaopoopoga: I le ala o lea e tusi atoa i ni uga tofotofa, o le uga spiral steel e faʻaopoopoga lelei i le faiaoga faiaga ina e tuu mai i lea e lelei o ni uga vae ma ni uga strips, e faia e lelei lea e faiaoga faʻamolemole, ma e faiaoga faʻamanino lelei.

Faʻamanino lelei i le faiaoga faʻalava: O le uga spiral steel e faia i le faiaoga faʻalava spiral submerged arc. E tutusa lea lenei faiaoga faʻalava i le faʻamanino lelei ma le faʻasilo, e faia e lelei lea e faiaoga faʻamanino ma faʻamanino o le ua.

Faʻatupuga vave: O le faʻatupuga vave e faia e lelei lea e faiaoga faʻamanino i le aoga o lea e lelei o ni mea, e faia e lelei lea e faiaoga faʻamanino ma faʻamanino o le ua.

Togafitiga e tetee atu ai i le pala: Ina ia faʻalauteleina le ola tautua ma puipuia le pala, o paipa uʻamea faʻasolosolo e masani ona faʻaauupegaina i ni ufiufi faʻapitoa e tetee atu ai i le pala, e pei o le efuefu epoxy efuefu ufiufi i fafo

Faʻavaomalo Faʻatulagaina: O le gaosiga o paipa uʻamea faʻasolosolo e mulimulitaʻi i se faʻasologa o faʻavaomalo tulaga faʻatulagaina, pei o le ISO 3183:2019, faʻamautinoaina le tumau i le lelei ma le faʻatinoina.

Faʻafouga faʻatekonolosi: I nisi o poloketi tetele o paipa, e pei o le Central Asia Natural Gas Pipeline Project, ua faʻaaogaina le tele o tekinolosi fou, e aofia ai le faʻaaogaina o paipa faʻapipiʻi, faʻaaogaina o le ultrasonic flow meters, ma RTTM auala o le mauaina

Fetuutuunai i le siosiomaga: E mafai ona faaaogā paipa uʻamea i siosiomaga eseese, e aofia ai le sopoia o eleele lavelave e pei o vaitafe ma le toafa o Gobi, ae ia uaʻi atu i le puipuiga o le siosiomaga ma le puipuiga o le siosiomaga.

Faʻatasi mauga o le lauiloa: O le tatau faʻatasi mauga e afai i mea ai le faʻatatau fesoasoani ma le faʻamaulalo totonu, e lelei ona faia leva le aso e tusa atu i le faʻatatau mo le tautua ma le faʻatasi mauga o le lauiloa.

Faʻatasi tulafono: O le galuega o le faʻatatau spiral steel pipes i le faʻatasi o le gas pa'apa'a, e lelei ona faia leva le tatau faʻatasi tulafono, e faʻatino le mafua'aga o le tala'i fa'atatau, e fa'amolemole le fa'ato'o mai i le aiga ma le taumafaiga o le tausagi ma le fa'atasi tulafono.

O le spiral steel pipes tele lalolagi e lelei ona faia leva le tatau fa'atasi mauga, le mafua'aga, le fa'atatau fa'amanatu ma le fa'atatau tu'u vave, ma e faia leva le mataupu i manatu i le vaega o le fa'atatau tele i lalo ma le lalo.
