O le eseesega i le tau maketi i le va o paipa uʻamea manifinifi puipui ma paipa uʻamea mafiafia puipui faʻalagolago i le gaosiga o le gaosiga, tau o meafaitino, fanua talosaga ma manaoga. O loʻo taua i lalo a latou eseesega autu i tau ma felauaiga:

1. Eseesega tau maketi
Paipa u'amea lamolemole puipui manifinifi:

Tau maualalo: Ona o le mafiafia o le puipui manifinifi, faʻaitiitia mea mataʻutia o loʻo faʻaaogaina, ma o le tau o gaosiga e maualalo.

Faʻaaogaina lautele: Faʻaaogaina i taimi e maualalo ai manaʻoga mo le malosi ma le faʻamalosi malosi, e pei o le fausiaina, teuteuga, felauaiga o le suavai, ma isi, ma le tele o manaʻoga maketi.

Laiti fesuiaiga o tau: E masani lava, o le tau e mautu ma e matua afaina lava i le maketi uamea.

Paipa u'amea mafiafia puipui puipui:

Tau maualuga: O le mafiafia o le puipui e tele, sili atu mea mata e faʻaaogaina, ma o le gaosiga o le gaosiga e faigata, e mafua ai le maualuga o tau.

Manaoga maualuga: E masani ona faʻaaogaina i fanua e maualuga le mamafa ma le maualuga o le faʻatulagaina o manaʻoga, e pei o masini masini, petrochemicals, boilers, ma isi mea, faʻatasi ai ma manaʻoga maualuga mo le malosi faʻamalosi ma le faʻafefe.

Tau maualuga ma felafolafoaiga tetele: Ona o le manaʻomia malosi mo paipa uʻamea mafiafia puipui i fanua faʻapitoa, o le tau e fesuisuiaʻi tele, aemaise lava pe a siitia le tau o mea mata uamea.
2. Puipuiga o felauaiga
Paipa u'amea lamolemole puipui manifinifi:

Faigofie ona faʻaleagaina: Ona o le puipui manifinifi o le paipa, e faigofie ona faʻaleagaina e malosiaga i fafo i le taimi o felauaiga, aemaise lava pe a faʻapipiʻi ma faʻapipiʻi.
Taofi le maosi: O le pito i luga o paipa manifinifi puipui e faigofie ona faʻaleagaina, ma e tatau ona faia ni puipuiga talafeagai, e pei o le ufiufi o luga i ie palasitika poʻo isi mea puipuia.
Faʻamau faʻamau: E manaʻomia le faʻaogaina o fusi vaivai poʻo fusi uʻamea faʻapitoa e faʻapipiʻi e aloese ai mai le faʻaleagaina o le tino paipa ona o le faʻamalosi tele.
Paipa u'amea mafiafia puipui puipui:

Mamafa mamafa: O paipa uʻamea mafiafia puipui e mamafa, ma e manaʻomia mea faʻapipiʻi tetele i le taimi o felauaiga, ma o mea faigaluega felauaiga e manaʻomia ona lava le gafatia.
Fa'aputuga mautu: Ona o le mamafa o paipa u'amea, paleni ma le mautu e tatau ona mafaufau i le taimi o le fa'aputuina e aloese ai mai le ta'avale po'o le pa'u, aemaise lava i le taimi o felauaiga e puipuia ai le fa'ase'e pe feto'ai.
Saogalemu o felauaiga: I le taimi o felauaiga mamao, e tatau ona gauai faapitoa i meafaigaluega e pei o paʻu faʻafefe ma poloka lagolago i le va o paipa uʻamea e aloese ai mai le faʻaleagaina e mafua mai i feeseeseaiga ma aʻafiaga.
O le tau o paipa uʻamea e leai ni paʻu manifinifi e maualalo, ae tatau ona gauai atu i le puipuia o le faʻaleagaina ma le faʻaleagaina o luga i le taimi o felauaiga; aʻo maualuga atu le tau o paipa uʻamea mafiafia puipui, ma e tatau ona totogi faʻapitoa i le saogalemu, mautu ma le mamafa o le puleaina i le taimi o felauaiga. Ae ui i lea, o paipa uʻamea e leai ni mea faʻapitoa ma mea faʻapitoa e manaʻomia pea ona iloiloina moni.
O paipa u'amea fa'alelei a le Sanonpipe e aofia ai paipa fa'avela, paipa fetilaisa, paipa suauu, ma paipa faufale.
