Paipa u'amea lamolemolee fa'aulu mai se uamea lapotopoto atoa, ma o paipa uamea e aunoa ma ni uelo i luga ua ta'ua o paipa uamea. E mafai ona vaevaeina paipa uʻamea vevela i paipa uʻamea uʻamea vevela, uʻamea uʻamea uʻamea malulu, faʻamaʻi-tosoina paipa uʻamea, faʻafefeteina paipa uʻamea, ma paipa paipa e tusa ai ma metotia gaosiga. Ua vaevaeina paipa u'amea seamless i ni ituaiga se lua: lapotopoto ma fa'apitoa-foliga e tusa ai ma o latou foliga cross-sectional. O paipa fa'apitoa e aofia ai sikuea, elliptical, tafatolu, hexagonal, meleni-foliga, fa'a-fetu, ma fa'au'u. Ole pito maualuga ole lautele ole 900mm 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 masani ona fa'aaogaina e pei o paipa vili suau'u suau'u, paipa ta'e petrochemical, paipa fa'avevela, paipa fa'apipi'i, ma paipa u'amea fa'atonu maualuga mo ta'avale, palau, ma va'alele.
O paipa u'amea lamolemole e fa'aaogaina lautele.
1. O paipa uʻamea faʻaogaina lautele o loʻo taʻavale mai le 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 faamoemoega eseese, e mafai ona vaevaeina i ni vaega se tolu:
O se ituaiga. Tuuina atu e tusa ai ma vailaʻau faʻapipiʻi ma mea faʻainisinia;
Bay e tusa ai ma faʻatinoga faʻainisinia;
C. E tusa ai ma le suʻesuʻega o le vai. O paipa uamea o loʻo tuʻuina atu i vaega A ma le B. Afai e faʻaaogaina e faʻafefe ai le mamafa o le vai, e tatau foi ona faia se suʻega hydraulic.
3. O paipa fa'apitoa mo fa'amoemoega fa'apitoa e aofia ai paipa fa'ama'i mo fa'avela, vaila'au, eletise eletise, paipa u'amea mo fa'afanua, ma paipa fa'afefe mo suau'u.
O paipa u'amea e leai se mea e maua ai se vaega gaogao ma o lo'o fa'aaogaina i le tele o paipa mo le felauaiga o vai, e pei o paipa mo le fa'asu'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 le pi'o ma le malosi o le torsion ma ose vaega e taugofie. Faʻaaogaina lautele i le gaosiga o vaega faʻavae ma vaega faʻainisinia, e pei o paipa vili suauʻu, taʻavale faʻasalalau, uila uila, fata uʻamea mo le fausiaina, ma isi mea. ma le faagasologa. itula faigaluega.
E lua fa'agasologa o le gaosiga mo paipa u'amea e leai ni fa'aoga (ta'avale malulu ma ta'avale vevela):
①Main gaosiga faagasologa o vevela-taai seamless paipa (△autu asiasiga faagasologa):
Tube avanoa avanoa ma asiasiga △→ faʻavevela faagaau → perforation → taʻavale paipa → faʻauʻu reheating → faʻamauina (faʻaitiitia) le lautele → vevela vevela△ → faʻamaʻaʻaina faʻauʻu → maeʻa → asiasiga△ (e le faʻaleagaina, faaletino ma vailaʻau, asiasiga nofoa) → i totonu teuina
②O le fa'agasologa autu o le gaosiga o paipa u'amea e le fa'afefeteina malulu:
Sauniuniga gaogao → pikiina ma lubrication → ta'avale malulu (tusi) → togafiti vevela → fa'asa'o → mae'a → asiasiga → teuina
