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. Po'o le Su'ega Hydraulic e mafai ona sui e le Eddy Current Testing po'o 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, Po'o Rockwell Su'ega Malosi e Faia i luga o se Fa'ata'ita'iga Mai Lota Ta'itasi.
