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.

Uamea uamea 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, suauʻu, textile, faafomai, meaai, masini ma isi alamanuia, corrosion-tetee paipa ma vaega fausaga ma vaega.

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

paipa u'amea lamolemole

Ona o lona faagasologa o le gaosiga 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-toso (loloa) paipa ua vaevaeina i paipa lapotopoto ma faapitoa-foliga paipa lua ituaiga.

A. Aotelega o le faagasologa o le tafe

Taavale vevela (extruded seamless paipa uʻamea): Billet tube lapotopoto → faʻamafanafana → perforation → tolu-loaiga koluse taʻavale, faʻaauau taʻavale poʻo extrusion → faagaau stripping → sizing (po o le faaitiitia) → cooling → faagaau avanoa → faasaʻo → suʻega mamafa vai (po o le iloa o faaletonu) → faailoga → teuina.

Tusia malulu (ta'avale) paipa u'amea seamless: pa'u lapotopoto → vevela → perforation → ulutala → annealing → pickling → oiling (pepa apamemea) → multi-pass ata malulu (taavale malulu) → paipa avanoa → vevela → fa'asa'o → su'ega o le mamafa o le vai (su'esu'e sese) → fa'ailoga → teuina.
