O paipa u'amea e leai ni mea e fa'afefeteina mai le u'amea lapotopoto atoa, ma o paipa u'amea e aunoa ma ni uelo i luga e ta'ua o paipa u'amea.E tusa ai ma le faiga o le gaosiga, e mafai ona vaevaeina paipa uʻamea uʻamea i le vevela-taai paipa uʻamea uʻamea, uʻamea uʻamea uʻamea malulu-loloa, malulu-tosi uʻamea uʻamea paipa, extruded seamless paipa, ma paipa pito i luga.E tusa ai ma foliga faʻasolosolo, o paipa uʻamea e le faʻaogaina e vaevaeina i ni ituaiga se lua: lapotopoto ma faʻapitoa.O paipa fa'apitoa e aofia ai le sikuea, oval, tafatolu, hexagonal, fatu melon, fetu, ma paipa fa'au.Ole pito maualuga ole lautele ole 22000mm ma ole la'ititi la'ititi ole 4mm.E tusa ai ma faamoemoega eseese, o loʻo i ai paipa uʻamea mafiafia puipui ma paipa uʻamea manifinifi puipui.O paipa u'amea 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 faufale maualuga mo ta'avale, ta'avale, ma va'alele.
O paipa u'amea lamolemole e fa'aaogaina lautele.
1. O paipa uʻamea faʻaogaina lautele o loʻo taʻavale e masani masani carbon structural steel, low-alloy structural steel or alloy structural steel, ma le tele o mea e gaosia, ma e masani ona faʻaaogaina e pei o paipa poʻo vaega faʻavae mo le felauaiga o vai.
2. E tusa ai ma faʻamoemoega eseese, e mafai ona tuʻuina atu i ni vaega se tolu:
a.Tuuina atu e tusa ai ma le tuufaatasiga o vailaʻau ma mea faʻainisinia;
e.E tusa ai ma le faatinoga o masini;
i.E tusa ai ma le sapalai o le suʻega o le vai.O paipa u'amea e fa'atatau i vaega a ma le b.afai e fa'aaogaina e tatalia ai le mamafa o le vai, e tatau fo'i ona faia se su'ega hydraulic.
3. O paipa fa'apitoa fa'apitoa e aofia ai paipa e leai ni fa'aumu mo fa'afu, vaila'au ma eletise eletise, paipa u'amea fa'alelei mo geology, ma paipa fa'afefe mo suau'u.
O paipa u'amea e leai ni mea e maua ai se vaega o'ogo ma e fa'aaogaina tele e pei o paipa mo le felauaiga o vai, e pei o paipa mo le felauaiga o suau'u, kesi masani, kesi, vai ma nisi mea mautu.Pe a faatusatusa i le uamea malo e pei o le uamea lapotopoto, o le paipa u'amea e mama i le flexural ma le torsional malosi ma o se vaega tau tamaoaiga.Fa'aaoga lautele i le gaosiga o vaega fa'avae ma vaega fa'ainisinia, e pei o paipa vili suau'u, fa'a'ave'au ta'avale ta'avale, fa'avaa uila, ma fata u'amea fa'aaogaina i le fausiaina.O paipa uʻamea e faʻaaogaina e fai ai vaega mama, lea e mafai ona faʻaleleia ai le faʻaogaina o meafaitino, faʻafaigofie faiga gaosiga, ma faʻasaoina mea ma gaioiga.itula faigaluega.
E lua fa'agasologa o gaosiga autu mo paipa u'amea lamolemole (ta'avale malulu ma ta'avale vevela):
①Main gaosiga faagasologa occcccccc (△autu asiasiga faagasologa):
Sauniuniga o paipa paipa △ → faʻamafanafanaina → faʻafefe → taʻavale paipa → toe faʻamafanafana paipa → faʻamauina (faʻaititia) le lautele → vevela △ → faʻamaʻi faʻamaʻi → maeʻa → asiasiga△ (e le faʻaleagaina, faaletino ma vailaʻau, asiasiga nofoa)→ i le teuina
②Main gaosiga faagasologa o malulu-taai paipa uʻamea seamless:
Sauniuniga gaogao → pikiina ma lubrication → ta'avale malulu (tusi) → togafiti vevela → fa'asa'o → mae'a → asiasiga → teuina
