1. Fa'atomuaga pu'upu'u o paipa fa'avae

Fa'aoga paipa mo le fausaga (GB / T8162-2008) mo le fausaga lautele ma le fausaga faʻainisinia o le faʻaogaina o le paipa.

u'amea u'amea seamless paipa mo fausaga (GB/T14975-2002) o se vevela-taai (extruded, faalauteleina) ma le malulu-toso (taavale) paipa seamless faia i uʻamea uʻamea faʻaaogaina i vailaʻau, suauu, ie, faafomai, meaai, masini ma isi alamanuia, paipa e mafai ona pala ma vaega fausaga ma vaega.

GB / T8162-2008 (paipa seamless mo fausaga) e masani ona faʻaaogaina mo le fausaga lautele ma le fausaga faʻainisinia. O mea faʻapitoa (igoa): uamea carbon 20, 45 uamea, Q235, uamea uamea Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo , 42CrMo ma isi.

paipa u'amea lamolemole

Ona o lona gaosiga faagasologa e ese, ua vaevaeina i vevela ta'avale (extruded) faagaau u'amea seamless ma le malulu toso (loloa) faagaau u'amea seamless lua kinds.Cold-tosi (loloa) paipa ua vaevaeina i paipa lapotopoto ma faapitoa-foliga paipa lua. ituaiga.

A. Aotelega o le faagasologa o le tafe

Ta'avale vevela (fa'apipi'i u'amea fa'a'au'au fa'au'u): pi'ila fa'a'a'ai lapotopoto → fa'avevela → fa'a'au'au → ta'avale koluse tolu-lo'a, ta'avale faifaipea po'o le fa'a'ave'esea → fa'alava fa'alava → sizing (po'o fa'aitiitia) → fa'alili → fa'alava avanoa → fa'asa'o → su'ega o le vai (po'o le fa'aletonu iloa) → maka → teuina.

Ata maalili (taavale) paipa u'amea lapotopoto: fa'amalo fa'amalo → fa'avevela → fa'aoso → fa'aulutala → fa'ama'i → pikiina → fa'asu'u (pepa apamemea) → tele-pass ata malulu (ta'avale malulu) → paipa avanoa → vevela → fa'asa'o → su'ega mamafa vai. (su'esu'e sese) → maka → teuina.
