Tulaga lelei o paipa u'elo fa'apipi'i i le fauga o paipa kasa fa'alenatura
O paipa fa'apipi'i fa'apipi'i o lo'o gaosia e fa'aoga ai se fa'agasologa e manu'a ai fasi uamea ma fa'aauau pea ona uelo e maua ai se si'osi'omaga.O lenei metotia e maua ai paipa malolosi, umi ma fetuutuunai e fetaui lelei ma manaʻoga o felauaiga kasa masani.
O se tasi o fa'amanuiaga autu o le paipa ueloina o le maualuga o le malosi-i-mamafa.O le mea lea e fetaui lelei mo paipa mamao aua e mafai ona tatalia le mamafa i totonu ma fafo e faʻaaogaina i le taimi o felauaiga kesi masani e aunoa ma le faʻaleagaina o le faʻatulagaina o le faʻamaoni.E le gata i lea, o le faʻaogaina o le faʻaogaina o le spiral e faʻamautinoa ai le tutusa o le mafiafia o le paipa, faʻaleleia atili lona malosi ma le tetee atu i le faʻaleagaina.

E le gata i lea, o paipa uʻamea uʻamea faʻasolosolo e sili ona lelei le faʻafefeteina, o se mea taua i totonupaipa kasa masanifausiaina.O mea fa'aletino ole u'amea fa'atasi ma fa'alavalava fa'alelei ma fa'alavalava e fa'amaualuga ai nei paipa i a'afiaga leaga ole kasa fa'alenatura ma isi mea leaga o lo'o iai ile si'osi'omaga.E le gata e faʻalauteleina ai le ola o le paipa, e faʻaitiitia ai foʻi manaʻoga faʻaleleia ma tau faʻatatau.
I le faaopoopo atu i ana mea faʻainisinia ma faʻamaʻi, o paipa faʻapipiʻiina e fetaui lelei mo le faʻapipiʻiina i le tele o laufanua ma tulaga o le siosiomaga.O lona fetuutuuna'i e mafai ai ona faigofie le faʻaogaina ma le faʻapipiʻiina o faʻalavelave faʻalavelave, ma avea ai ma se filifiliga taugofie mo laufanua faigata.E le gata i lea, o sooga faʻapipiʻi o paipa paipa e matua malosi lava, faʻamautinoaina o paipa e le mafai ona tafe i le taimi atoa o latou olaga tautua.
O le isi fa'amanuiaga o paipa uelo fa'asolosolo o lona tau-lelei.O le gaosiga o gaosiga e mafai ai ona maua le maualuga ma le fa'aogaina lelei o mea mata i se tau fa'atauvaga fa'atusatusa i isi mea paipa.E le gata i lea, o le umi ma le maualalo o le tausiga o le paipa uelo faʻasolosolo e fesoasoani e faʻaititia le tau o le taamilosaga o le olaga, ma avea ai ma filifiliga faʻapitoa mo le faʻaogaina o paipa kesi masani.
E le gata i lea, o le fetuutuuna'i o paipa uelo faʻasolosolo e talafeagai mo le tele o taʻaloga, mafiafia puipui ma tulaga mamafa e faʻafetaui ai manaʻoga eseese o faiga faʻaogaina kesi masani.O lenei fegalegaleai e mafai ai ona faʻamalieina mamanu paipa e faʻafetaui ai manaʻoga faʻapitoa faʻaogaina, faʻamautinoa le lelei atoatoa ma le lelei.
I se aotelega, o le faʻaaogaina opaipa u'amea fa'ameameai totonu o le kasa masani faufale e ofoina atu le tele o tulaga lelei, e aofia ai le malosi maualuga, corrosion tetee, fetuutuunai ma tau-lelei.O le i'uga, o lo'o tumau pea le filifiliga muamua mo tagata fa'apolofesa fa'apisinisi o lo'o su'e fa'atuatuaina, fa'agata fa'ama'i fa'avevela kesi fa'alenatura.E ala i le fa'aogaina o mea lelei o le paipa uelo fa'asolosolo, e mafai ai e le au pa'aga ona fa'amautinoaina o lo'o fa'agaoioia atina'e kesi fa'alenatura ma le saogalemu, lelei ma tumau mo tausaga a sau.
