O le paipa uʻamea e leai se mea e faia e ala i le faʻafefeteina o le uʻamea lapotopoto atoa, ma o le paipa uʻamea e aunoa ma se faʻauʻu i luga o le pito e taʻua o paipa uʻamea.E tusa ai ma le faiga o le gaosiga, e mafai ona vaevaeina paipa uʻamea faʻafefete i paipa uʻamea faʻafefe vevela, faʻamaʻalili paipa uʻamea faʻafefe, paipa uʻamea faʻafefe malulu, paipa uʻamea extruded, ma paipa paipa.E tusa ai ma foliga o le cross-sectional, ua vaevaeina paipa uʻamea seamless i ni ituaiga se lua: lapotopoto ma faʻapitoa-foliga, ma faʻapitoa-foliga faagaau e eseese foliga faigata e pei o le sikuea, oval, tafatolu, hexagonal, melon-foliga, fetu-foliga, ma faagaau apau.Ole maualuga maualuga e oʻo ile 900mm ma le laʻititi laʻititi ole 4mm.E tusa ai ma faʻaoga eseese, o loʻo i ai paipa uʻamea mafiafia puipui ma paipa uʻamea manifinifi puipui.O paipa u'amea e leai ni mea e masani ona fa'aaogaina e pei o paipa viliina suau'u, paipa ta'e mo alamanuia petrochemical, paipa fa'avevela, paipa fa'apipi'i, ma paipa u'amea fa'atonu maualuga mo ta'avale, ta'avale, ma va'alele.

O se paipa u'amea e le fa'aogaina i luga o le tu'uga o lona va'aiga.E tusa ai ma auala eseese o le gaosiga, ua vaevaeina i paipa vevela, paipa malulu, paipa malulu, paipa extruded, paipa paipa, ma isi, o ia mea uma ei ai a latou lava tulafono faatonutonu.

O meafaitino e aofia ai le masani ma le maualuga o le carbon structural steel, u'amea u'amea maualalo, u'amea u'amea, ma isi.

E tusa ai ma le faʻamoemoe, e vaevaeina i ni vaega se lua: faʻamoemoega lautele (mo vai, paipa kesi ma vaega faʻavae, vaega faʻainisinia) ma faʻapitoa faʻapitoa (mo boilers, suʻesuʻega faʻafanua, bearings, acid resistance, ma isi).

O le lautele pito i fafo o le paipa faʻafefeteina vevela e masani ona sili atu nai lo le 32mm, ma le mafiafia o le puipui e 2.5-200mm.Ole pito i fafo ole paipa u'amea e le mafai ona o'o ile 6mm, ma le mafiafia o le puipui e mafai ona o'o ile 0.25mm.O le ta'avale e maualuga le sa'o o itu nai lo le ta'avale vevela.E masani lava, o paipa uʻamea e leai ni mea e faia i le 10, 20, ma isi, faʻapipiʻi uʻamea fausaga.P5, P9, P11, P22, P91, P92, 15mog, 20mog, 12crmog, 15crmog, 12cr2mog, 12crmovg, ma isi o.10, 20ma isiuamea maualalo kaponi paipa seamlesse masani ona faʻaaogaina mo paipa feʻaveaʻi vai.E masani lava, o paipa u'amea lamolemole e fa'aogaina e fa'amautinoa ai le malosi ma fa'ata'ita'iga su'ega.O paipa uʻamea faʻafefe vevela e tuʻuina atu i se tulaga vevela vevela poʻo le vevela;o loʻo tuʻuina atu paipa uʻamea malulu malulu i se tulaga vevela.
