Umi:

O le umi masani o paipa uʻamea e 4 000 mm ~ 12 000 mm. A maeʻa faʻatalanoaga i le va o le faʻatau ma le faʻatau, ma faʻatumu le konekarate, e mafai ona tuʻuina atu paipa uʻamea ma le umi e sili atu i le 12 000 mm poʻo le puupuu nai lo I 000 mm ae le itiiti ifo i le 3 000 mm; puupuu umi Ole numera o paipa u'amea e itiiti ifo i le 4,000 mm ae le itiiti ifo i le 3,000 mm e le tatau ona sili atu i le 5% o le aofa'i o paipa u'amea tu'uina atu.

Tilivaina mamafa:
A tuʻuina atu le paipa uʻamea e tusa ai ma le pito i fafo o le pito i fafo ma le mafiafia o le puipui poʻo le pito i totonu ma le mafiafia o le puipui, o le paipa uamea e tuʻuina atu e tusa ai ma le mamafa moni. E mafai foʻi ona tuʻuina atu e tusa ai ma le mamafa faʻapitoa.
Pe a tuʻuina atu le paipa uʻamea e tusa ai ma le faʻailoga pito i fafo ma le laʻititi laʻititi o puipui, e tuʻuina atu le paipa uʻamea e tusa ai ma le mamafa moni; e feutagai le vaega o sapalai ma manaoga. Ma o loʻo faʻaalia i totonu o le konekarate. O le paipa uʻamea e mafai foi ona tuʻuina atu e tusa ai ma le mamafa faʻapitoa.

Fa'apalepale mamafa:
E tusa ai ma manaʻoga o le tagata faʻatau, pe a maeʻa feutagaiga i le va o le faʻatau ma le faʻatau, ma i totonu o le konekarate, o le eseesega i le va o le mamafa moni ma le mamafa o le paipa uʻamea e tatau ona fetaui ma manaʻoga nei:
a) paipa u'amea tasi: ± 10%;
b) O vaega ta'itasi o paipa u'amea ma le lapopo'a la'ititi o le 10 t: ± 7.5%.

Su'ega Manaoga

Su'ega Fa'asuavai:

O le paipa u'amea e tatau ona fa'ata'ita'i fa'ata'oto ta'itasi. Ole mamafa ole su'ega ole 20 MPa. I lalo o le mamafa o le suʻega, o le taimi faʻamautu e le tatau ona itiiti ifo i le 10 s, ma e le tatau ona tafe le paipa uʻamea.

A mae'a ona malilie le tagata fa'aoga, e mafai ona sui le su'ega hydraulic i su'ega eddy i le taimi nei po'o le su'esu'eina o le fa'amaneta.

Su'ega le fa'aleagaina:

O paipa e manaʻomia le tele o asiasiga e tatau ona siaki faʻatasi ma le ultrasonic. A maeʻa le feutagaiga e manaʻomia le maliega a le pati ma faʻamaonia i totonu o le konekarate, e mafai ona faʻaopoopo isi suʻega e le faʻaleagaina.

Su'ega Fa'amafola:

O paipa e iai le lautele i fafo e sili atu i le 22 mm e tatau ona faia i se suʻega faʻamafola. Leai se delamination va'aia, ila pa'epa'e, po'o ni mea leaga e tatau ona tupu i le taimi atoa o le su'ega.

Su'ega Su'e:

E tusa ai ma manaʻoga o le faʻatau ma taʻua i totonu o le konekarate, o le paipa uʻamea ma le pito i fafo ≤76mm ma le mafiafia puipui ≤8mm e mafai ona faia suʻega suʻe. O le faʻataʻitaʻiga na faia i le vevela o le potu ma le taper o le 60 °. A maeʻa le faʻafefe, o le fua o le mumu o le pito i fafo e tatau ona fetaui ma manaʻoga o le laulau o loʻo i lalo, ma o mea suʻega e le tatau ona faʻaalia ni taʻe pe sae.
