ASTM A213 GR.T22 SA333 GR.6 Fa'au'u u'amea e leai se fa'ameamea mo le tu'uina atu o sua.

fa'alava uamea seamless ei ai le tele o fa'aoga.

1, o le faamoemoega lautele seamless paipa uʻamea o loʻo taʻavale e masani carbon structural uʻamea, uʻamea faumea structural uamea po o uʻamea fausaga uʻamea, o le gaosiga aupito maualuga, e masani ona faʻaaogaina mo le felauaiga o paipa vai po o vaega fausaga.

2, e tusa ai ma le faʻaaogaina o sapalai eseese i vaega e tolu:

A. Tuuina atu e tusa ai ma le tuufaatasiga o vailaau ma mea tau masini;

e. Tuuina atu e tusa ai ma mea tau masini;

i. Tuuina atu e tusa ai ma suʻega hydraulic. O paipa uʻamea e tuʻuina atu e tusa ai ma le vasega a ma le Vasega b, pe a faʻaaogaina e faʻafefe ai le mamafa o le vai, e tatau foi ona faia i suʻega hydrostatic.

3, o le faʻamoemoega faʻapitoa o le faʻaogaina o paipa faʻatasi ma le paipa faʻafefeteina paipa, mana kemisi, geological seamless paipa uʻamea ma suauu paipa seamless ma isi.

Seamless paipa uʻamea o loʻo i ai vaega gaogao, faʻaaogaina lautele mo le faʻafeiloaʻi o le paipa vai, e pei o le faʻasalalauina o le suauu, kasa masani, kesi, vai ma nisi mea mautu, ma isi. Faʻatusatusa i le uamea malo e pei o le uamea lapotopoto, o le paipa uamea o se ituaiga o uʻamea o le tamaoaiga ona o lona mamafa mama ma le tutusa o le punou ma le malosi torsional.

E masani ona faʻaaogaina i le gaosiga o vaega faʻavae ma vaega faʻainisinia, e pei o le paipa vili suauʻu, taʻavale faʻasalalau taʻavale, uila uila ma fata uamea faʻaaogaina i le fausiaina. E mafai ona faʻaleleia le faʻaogaina o meafaitino, faʻafaigofie le gaosiga o gaosiga, faʻasaoina meafaitino ma itula faʻagaioiga, ma ua faʻaaogaina lautele i le gaosiga o paipa uʻamea.
