Su'ega Manaoga
Su'ega eletise
E tatau ona faia le su'ega o le vai mo paipa u'amea 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 le leakage o paipa uʻamea e le faʻatagaina.
Su'ega fa'amafola
E tatau ona faia le su'ega fa'amafola mo paipa u'amea e sili atu i le 22 mm le lautele i fafo
Su'ega afi
O paipa u'amea e le sili atu i le 76 mm ma le mafiafia o le puipui e le sili atu i le 8 mm e tatau ona fa'alautele le su'ega. Ole su'ega fa'amumu e tatau ona faia ile vevela ole potu. O le fua o le fulafula pito i fafo o le fa'ata'ita'iga pe a mae'a le taper pito i luga o le 60% o le fa'amumu e tatau ona fetaui ma mana'oga o le laulau 7. E leai ni ta'e po'o ni ta'e e fa'atagaina i luga o le fa'ata'ita'iga pe a uma le mu. E tusa ai ma manaʻoga o le tagata e manaʻomia ma faʻamauina i totonu o le konekarate, e mafai foi ona faʻaogaina le sila faʻapipiʻi mo le faʻalauteleina o suʻega.
Su'ega le fa'aleagaina
O paipa uʻamea e tatau ona tuʻuina atu i lalo ole suʻesuʻega faʻaletonu ultrasonic taʻitasi e tusa ai ma aiaiga o le GB / T 5777-2008. E tusa ai ma manaʻoga o le tagata e manaʻomia, o isi suʻega e le faʻaleagaina e mafai ona faʻaopoopo pe a maeʻa feutagaiga i le va o le faʻatau oloa ma le tagata faʻatau ma faʻaalia i le konekarate.
Su'ega a'afia i totonu ole va'aiga
E tatau ona faia le su'ega a'oa'oga mo le paipa u'amea e le'o (vevela). O le suʻega metotia e tatau ona tusa ai ma aiaiga o le auala Saina E i le GB / T 4334-2008, ma e le faʻatagaina le faʻaleagaina o le intergranular pe a uma le suʻega.
A maeʻa feutagaiga i le va o le faʻatau oloa ma le tagata e manaʻomia, ma faʻamauina i totonu o le konekarate, e mafai e le tagata faʻatauvaʻa ona faʻatulagaina isi metotia faʻataʻitaʻiga.
