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

faagaau uamea seamless o loʻo i ai le tele o faʻaoga.

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.

Pipa u'amea seamless o lo'o i ai vaega omo, fa'aaoga lautele mo le fa'auluina o le paipa vai, e pei o le fa'auluina o le suau'u, kasa masani, kesi, vai ma nisi mea mautu, ma isi. Fa'atusaina ma le sila mausalī e pei o le u'amea lapotopoto, paipa uamea o se ituaiga u'amea vaega tau tamaoaiga. ona o lona mamafa mama ma tutusa le punou ma torsional malosi.

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.
