Su'ega Fa'a-Hydraustatic:
E tatau ona tofotofoina le Paipa U'amea i le ta'itasi i le faiga fa'a-hydraulic. O le mamafa maualuga o le su'ega e 20 MPa. I lalo o le mamafa o le su'ega, e le tatau ona i lalo ifo o le 10 S le taimi e fa'amautu ai, ma e le tatau ona tafe le paipa u'amea. Pe mafai fo'i ona suia le su'ega hydraulic i le su'ega o le Eddy Current po'o le su'ega o le Magnetic Flux Leakage.
Su'ega e le fa'aleagaina:
O paipa e manaʻomia nisi asiasiga e tatau ona siaki taʻitasi i le ultrasonic. A maeʻa ona manaʻomia le maliega a le vaega e feutagaʻi ma o loʻo faʻamaoti mai i le konekarate, e mafai ona faʻaopoopo isi suʻega e le faʻaleagaina.
Su'ega Fa'apa'u：
O paipa e sili atu le lautele i fafo i le 22 mm e tatau ona faia i ai se suega fa'amafolafola. E le tatau ona iai ni vaega e va'aia, ni ila pa'epa'e, po'o ni mea leaga i le taimi atoa o le fa'ata'ita'iga.
Su'ega o le Ma'a'a:
Mo Paipa o Vasega P91, P92, P122, ma le P911, Brinell, Vickers, po'o Rockwell Hardness Tests e tatau ona faia i luga o se fa'ata'ita'iga mai Lots ta'itasi.
