Fa'aaliga o gaosiga:
Talosaga:
O le paipa faʻafefete faʻapipiʻi o se ituaiga o paipa uʻamea, ma o lona faʻatinoga e sili atu le maualuga nai lo le masani
paipa u'amea lamolemole. Ona o le paipa uʻamea o loʻo i ai le tele o Cr, o lona maualuga maualuga o le vevela, maualalo le vevela
ma tetee corrosion e sili atu nai lo isi paipa uamea seamless. O lea la, o le paipa uʻamea e faʻaaogaina lautele i le suauu, vailaʻau,
eletise eletise, boiler ma isi alamanuia.
4140 mafiafia-pa le paipa seamless o le ultra-maualuga malosi malosi ma le malosi maualuga ma le faigata, faʻamaʻaʻa lelei, leai se manino.
fa'afefete ita, tapula'a maualuga le vaivai ma tete'e atu i le tele o a'afiaga pe a uma ona tineia ma fa'afefe, maualalo le vevela Lelei
a'afiaga faigata. O le uʻamea e talafeagai mo le gaosiga o palasitika palasitika tetele ma feololo e manaʻomia ai se malosi faʻapitoa
ma le faigata.
4140 mafiafia-puipui uiga paipa lelei ma le lautele o le talosaga: malosi maualuga, hardenability maualuga, faigata lelei, laiti
deformation i le taimi o tineia, malosi fetolofi maualuga ma malosi umi i le vevela maualuga. Fa'ailoga e mana'omia le maualuga
malosi ma vaega tele tineia nai lo uʻamea 35CrMo, e pei o mea tetele mo le locomotive traction, supercharger felauaiga
mea fa'aoga, au pito i tua, u'a fa'afeso'ota'i tele le uta ma kilipa vaipuna, e mafai fo'i ona fa'aoga Suau'u vaieli vili paipa so'oga ma fagotaga.
mea faigaluega i lalo ifo o le 2000m, ma e mafai ona fa'aoga mo fa'ailoga o masini punou, ma isi.
