O le vevela o le auaunaga e 580 ℃, ma o le ipu uamea e manaʻomia e maua ai le maualuga maualuga o le malosi o le tumau.O le ipu uamea e tuʻuina atu i le tulaga masani ma faʻafefe.12Cr1MoVG u'amea paipa e fa'avae i luga o le maualuga o le carbon structural steel, ma se tasi po'o ni nai elemene fa'apipi'i e fa'aopoopo lelei e fa'aleleia atili ai mea fa'ainisinia, ma'a'a'a ma fa'ama'a'a o le sila.O oloa e faia i ia uamea e masani lava ona manaʻomia togafitiga vevela (faʻasaʻo pe tineia ma faʻafefe);O vaega ma vaega e faia i latou e masani lava ona manaʻomia le faʻamalo ma le faʻafefe poʻo le faʻaogaina o vailaʻau (carburizing, nitriding, ma isi), faʻafefe i luga poʻo le faʻafefe maualuga aʻo leʻi faʻaaogaina.O le mea lea, e tusa ai ma mea eseese vailaʻau (tele carbon anotusi), vevela togafitiga faagasologa ma talosaga, e mafai ona vaevaeina ia uʻamea i carburized, Quenched ma ita ma nitrided steels.
Muamua, e mafai ona 100% toe faʻaaogaina, faʻasaoina o le malosi ma le puipuiga o le siosiomaga.
Lona lua, e matua maualuga lava le palasitika ma e mafai ona faʻaaogaina mo le gaosiga lona lua ma le gaosiga.
Lona tolu, o loʻo i ai le lelei o le vevela ma le maualuga o le vevela gafatia.
Lona fa, o loʻo i ai le faʻamaʻiina lelei o le faʻamaʻiina ma le faʻamaʻi.
Lona lima, e lelei le malulu ma le vevela faʻatinoga o gaioiga.
12Cr1MoVG o se ituaiga o chromium molybdenum uamea paipa uʻamea, lea o vaega autu o kemikolo o carbon 0.08-0.15, silicon 0.17-0.37, manganese 0.40-0.70, phosphorus e le sili atu nai lo 0.035, sulfur e le sili atu nai lo 0.035, chromium 0.035. molybdenum 0.25-0.35, alum 0.15-0.30, ma isi.
Muamua, e masani lava ona faʻaaogaina e gaosia ai faʻamau faʻapipiʻi maualuga mo le faʻavevelaina o luga o pusa vai faʻapipiʻi ma maualuga maualuga ma luga.
Lona lua, e masani ona faʻaaogaina i superheaters, ulutala ma ala ausa autu o totonu o le lotoifale maualuga-omiga, ultra-maualuga mamafa ma subcritical power station boilers.
Tolu, o paipa lapopoa tetele e masani ona faʻaaogaina e fai ma ulutala ma Ausa Ausa Autu ma faʻamaufaʻailoga i lalo ole 565 ℃.
Muamua, ta'avale vevela (extrusion seamless paipa) faagasologa faagasologa:
Pili paipa lapotopoto → fa'amafanafana → tu'ia → tolu ta'avale koluse ta'avale, ta'avale faifaipea po'o le fa'aulufaleina → tapeina o paipa → sizing (po'o fa'aitiitiga) → fa'alili → pili → fa'asa'o → su'ega hydrostatic (po'o le iloa o mea sese) → maka → faleteuoloa.
Lona lua, ata malulu (ta'avale) fa'agasolo lelei paipa uamea tafe:
Pili faagaau lapotopoto → fa'amafanafana → tu'ia → ulutala → fa'ama'i → pikiina → fa'apipi'i suau'u (pepa apamemea) → fa'ailoga malulu tele (ta'avale malulu) → paipa pili → togafitiga vevela → fa'asa'o → su'ega hydrostatic (po'o le iloa o mea sese) → maka → fale teu oloa.
