Pipa uamea ta'amilomilo mo Suauu felauaiga

Faamatalaga oloa

O paipa u'amea ta'amilomilo e masani ona fa'aogaina mo le felauaiga o le suau'u aua o paipa u'amea si'osi'omaga e tele mea lelei e fa'alelei ai mo felauaiga suau'u mamao. O nisi nei o vaega taua mo le fa'aogaina o paipa u'amea lilivau i felauaiga suau'u.

O paipa u'amea ta'amilomilo e masani ona fa'aogaina mo le felauaiga o le suau'u aua o paipa u'amea si'osi'omaga e tele mea lelei e fa'alelei ai mo felauaiga suau'u mamao. O nisi nei o mea taua mo le faʻaogaina o paipa uʻamea i totonu o le suauu:

1. Malosi maualuga ma le mautu: O paipa uʻamea uʻamea e faia i le uʻamea maualuga, lea e mafai ona tatalia le mamafa tele ma faʻamautinoa le mautu i le taimi o le fausiaina ma le faʻaaogaina.

2. Faʻafefete faʻafefe: O paipa uʻamea faʻapipiʻi e masani lava ona togafitia i le faʻapipiʻiina o le anti-corrosion coating poʻo le galvanizing, lea e fesoasoani e puipuia ai le pala o paipa uʻamea i siosiomaga faigata, e pei o le sami poʻo le eleele o loʻo i ai vailaʻau, ma faʻalauteleina ai lo latou ola tautua.

3. Maua le faufale maualuga: O le paipa u'amea spiral e tele le umi ma le lautele, lea e fetaui ma mana'oga faufale o le fa'aputuga o le alititai. I le taimi lava e tasi, o le auala fesoʻotaʻiga e faigofie ma e mafai ona faʻafesoʻotaʻi e ala i fesoʻotaʻiga filo poʻo le uelo, lea e faʻaleleia ai le lelei o le fausiaina.

4. Tamaoaiga: O le tau o le gaosiga o paipa u'amea silo e fai si maualalo ona o la latou gaosiga e faigofie ma o latou gaosiga lelei e maualuga, lea e maua ai le tamaoaiga.

5. Fetuuna'i: E mafai ona fa'aogaina paipa u'amea i le tele o galuega tau felauaiga suau'u, e aofia ai le eleele, alititai ma paipa felauaiga i lalo o tulaga faigata o le siosiomaga.

6. Saogalemu: I le taimi o le mamanu ma le fausiaina, o le saogalemu o paipa uʻamea o le a mafaufauina, e aofia ai le faʻaogaina o le faʻaogaina o faiga faʻafefeteina ma le pulea lelei o le lelei e faʻamautinoa ai le saogalemu o le felauaiga o suauu.

7. Faʻamatalaga faʻapitoa: O le gaosiga ma le faʻaogaina o paipa uʻamea faʻasolosolo e mulimulitai i se faasologa o tulaga faʻale-malo ma faʻavaomalo, e pei o le GB 50369-2014, ma isi.

8. Siosiomaga fetuutuunai: O paipa u'amea vilivili e mafai foi ona fa'avasegaina e tusa ai ma le fa'aogaina o siosiomaga fa'apitoa e fa'afetaui i tulaga eseese o le eleele, suiga o le vevela ma isi mea tau le siosiomaga.

9. Fa'atekonolosi fa'afouga: Fa'atasi ai ma le atina'eina o tekonolosi, o paipa u'amea fa'asolosolo o lo'o fa'afouina pea. Mo se faʻataʻitaʻiga, o le fausiaina o le paipa uʻamea muamua a le atunuʻu o loʻo i ai le maualuga o le kasa paipa ma le hydrogen doping galuega ua saunia ai le auala mo le faʻalauiloaina ma le faʻaogaina o le malosi o le hydrogen a le atunuʻu ma le faʻataunuʻuina o le "double carbon". O le sini e taua tele.

I se aotelega, ua faʻaaogaina lautele paipa uʻamea spiral i le fanua o felauaiga suauʻu ona o lo latou malosi maualuga, corrosion teteʻe, fausiaina faigofie ma le tamaoaiga. I le taimi lava e tasi, o le faʻaauau pea o le alualu i luma o tekinolosi ua faʻalauiloaina ai foʻi faʻaoga fou o paipa uʻamea uʻamea i felauaiga suauʻu, e pei o felauaiga hydrogen-doped.
