Pe a faʻatusatusa i le uamea malo e pei o le uʻamea lapotopoto, o le paipa uʻamea e mama i le mamafa pe a tutusa le malosi o le punou ma le torsion.O se u'amea fa'atauva'a fa'atauva'a ma e fa'aaogaina lautele e gaosia vaega fa'avae ma vaega fa'ainisinia, e pei o paipa vili suau'u, ta'avale fe'avea'i ta'avale, fa'avaa uila ma fata uamea fa'aaogaina i le fausiaina.O le gaosiga o vaega mama ma paipa uʻamea e mafai ona faʻaleleia ai le faʻaogaina o meafaitino, faʻafaigofie le gaosiga o gaosiga, ma faʻasaoina meafaitino ma itula faʻagaioiga, e pei o le taʻavale mama mama ma Siaki lima.I le taimi nei, o paipa uʻamea ua faʻaaogaina lautele mo le gaosiga.O paipa uamea o se mea taua tele mo ituaiga uma o auupega masani.O le paelo ma le paelo o fana e fai i paipa uamea.O paipa uamea e mafai ona vaevaeina i paipa lapotopoto ma paipa faʻapitoa faʻapitoa e tusa ai ma vaega eseese ma foliga.Talu ai ona o le vaega lapotopoto e sili ona tele i lalo o le tulaga o le taamilosaga tutusa, o le tele o vai e mafai ona feaveaia e paipa lapotopoto.E le gata i lea, pe a oʻo i le vaega o le mama i totonu poʻo fafo o le radial pressure, o le malosi e sili atu le tutusa.O le mea lea, o le tele o paipa uamea o paipa lapotopoto.

Tulaga masani: GB/T8163.

Main Steel Tube Vasega: 10, 20, Q345, ma isi.

E mafai fo'i ona tu'uina atu isi togi pe a uma ona feutaga'i ma tagata fa'atau.

Fa'agasologa Fa'atekonolosi

Ta'avale vevela (fa'apipi'i paipa u'amea lamolemole): fa'alava lapotopoto fa'alava → fa'avevela → tu'ia → tolu ta'avale koluse ta'avale, ta'avale faifaipea po'o le fa'aosoina → tapeina o paipa → sizing (po'o fa'aitiitiga) → fa'alili → fa'alava avanoa → fa'asa'o → su'ega hydrostatic (po'o le iloa o mea sese) → fa'ailoga → fale teu oloa.

Pipa u'amea fa'afefete (ta'avale) mālūlū: pili fa'a'au'au lapotopoto → fa'avevela → fa'aoso → fa'aulutala → fa'ama'i → pikiina → fa'apipi'iina o le suāu'u (fa'apipi'i apamemea) → fa'asolo tele ata malulu (ta'avale malulu) → pili → vevela → fa'asa'o → su'ega hydrostatic (fa'aletonu iloa) → maka → faleteuoloa.
