Su'ega Manaoga

Su'ega Fa'asuavai:

Ole paipa uamea e tatau ona fa'ata'ita'i ile vai ta'itasi. Ole maualuga ole su'ega ole 20 MPa. I lalo ole Su'ega Su'ega, ole Taimi Fa'amautu e le tatau ona itiiti ifo i le 10 S, ma le paipa u'amea e le tatau ona tafe.

A maeʻa ona ioe le tagata faʻaoga, e mafai ona sui le suʻega o le eletise e le Eddy Current Testing poʻo le Magnetic Flux Leakage Testing.

Su'ega le fa'aleagaina:

O paipa e mana'omia ai nisi su'esu'ega e tatau ona su'esu'eina ta'ito'atasi. A maeʻa le Fefaʻatauaʻiga 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 su'ega fa'amafola. Leai se Delamination Va'aia, Fa'ailoga Pa'epa'e, Po'o Fa'aleaga e tatau ona tupu i le taimi atoa o le fa'ata'ita'iga.

Su'ega Malosi:

Mo paipa o Vasega P91, P92, P122, ma le P911, Brinell, Vickers, poʻo Rockwell suʻega maʻaʻa e tatau ona faia i luga o se faʻataʻitaʻiga mai lotoa taʻitasi.

Su'ega Pi'o:

Mo paipa e sili atu i le NPS 25 le lautele ma le fua faatatau o le mafiafia o le puipui e 7.0 pe itiiti e tatau ona faia i le su'ega pi'o nai lo le su'ega fa'amafola. O isi paipa e tutusa lona lapoa pe sili atu i le NPS 10 e mafai ona tuʻuina atu le suʻega piʻo e suitulaga i le suʻega faʻamafola i lalo o le faʻatagaga a le tagata faʻatau.
