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 faʻafefete i paipa uʻamea faʻafefe vevela, faʻafefe uʻamea uʻamea uʻamea, paipa uʻamea faʻafefe malulu, paipa uʻamea faʻafefe, ma paipa pito i luga. E tusa ai ma le faʻasologa faʻasolosolo, o paipa uʻamea le lelei 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 i'u. Ole pito maualuga ole lautele ole 22000mm ma ole la'ititi la'ititi ole 4mm. E tusa ai ma faʻamoemoega 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 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, faʻatasi ai 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 suʻega o le vai. O paipa u'amea e fa'atatau i vaega a ma le b. afai e faʻaaogaina e faʻafefe ai le mamafa o le suavai, e tatau foi ona faia se suʻega hydraulic.
3. O paipa fa'apitoa fa'apitoa e aofia ai paipa e leai ni fa'aumu mo fa'avela, 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 se mea e maua ai se vaega gaogao ma e fa'aaogaina i le tele o paipa mo le felauaiga o vai, e pei o paipa mo le felauaiga o le 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'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 le gaosiga mo paipa u'amea lamolemole (ta'avale malulu ma ta'avale vevela):
①Main gaosiga faagasologa occcccccc (△autu asiasiga faagasologa):
Sauniuniga ma su'esu'ega o paipa paipa△→fa'avevela → fa'a'ave'esea → ta'avale paipa → toe fa'avevela (fa'aitiitiga) le lautele → togafitiga vevela△→ fa'ama'a'a'ai fa'au'au fa'auma → fa'amae'a → asiasiga△(e le fa'aleagaina, fa'aletino ma vaila'au, asiasiga nofoa) → i le teuina
②Main gaosiga faagasologa o le malulu-taai seamless paipa uʻamea:
Sauniuniga gaogao → pikiina ma lubrication → ta'avale malulu (tusi) → togafiti vevela → fa'asa'o → fa'auma → asiasiga → teuina
