12Cr1MoVG fa'amautinoaga lelei paipa u'amea fa'ameamea maualuga

Ona o faiga eseese o gaosiga, ua vaevaeina i le vevela ta'avale (extruded) paipa u'amea seamless ma malulu toso (loloa) paipa uamea seamless. O le paipa e toso (ta'avale) malulu ua vaevaeina i paipa lapotopoto ma paipa fa'apitoa.

a. Vaaiga lautele o le faagasologa

Hot lo'a (extruded) paipa u'amea seamless: lapotopoto tube avanoa → faamafanafana → perforation → tolu lola koluse ta'avale, fa'aauau ta'avale po'o extrusion → paipa stripping → sizing (po o le faaitiitia) → malulu → avanoa avanoa → fa'asa'o → hydrostatic su'ega (po'o le iloa o mea sese) → fa'ailoga → faleteuoloa.

O le paipa u'amea fa'afefete (ta'avale) malūlū: fa'alava lapotopoto fa'alava → fa'avevela → fa'ao'o → fa'aulutala → fa'ama'i → pikiina → fa'a'u'u (pepa apamemea) → fa'asolo tele ata malulu (ta'avale malulu) → paipa avanoa → vevela → fa'asa'o → su'ega hydrostatic (fa'aletonu iloa) → maka → faleteuoloa.
