Ole tulaga maualuga ole ASTM A335 P91 Fa'amea Su'ega Alloy Seel Paipa i Saina
Vaaiga lautele
O la tatou atinaʻe e faʻalagolago i meafaigaluega faʻapitoa, taleni sili ona lelei ma faʻaauau pea ona faʻamalosia malosiaga faʻatekonolosi mo a tatou paipa uʻamea faʻatau oloa, O le a faʻaauau pea ona tatou taumafai e faʻateleina la tatou kamupani ma tuʻuina atu oloa lelei lelei ma tau faʻamalosi. So'o se su'esu'ega po'o se fa'amatalaga e matua fa'afetaia. Manatua e pu'e fua mai ia i matou. O loʻo galue la matou kamupani i le faʻatonuga o le "faʻamaoni-faʻavae, galulue faʻatasi, faʻavae tagata, manumalo-malo galulue faatasi". Matou te faʻamoemoe e mafai ona matou maua se mafutaga faauo ma tagata fai pisinisi mai le lalolagi atoa
P91 e le gata o loʻo i ai le maualuga o le faʻamaʻiina o le faʻamaʻiina ma le maualuga o le vevela o le ausa, ae o loʻo i ai foi le malosi o le aʻafiaga ma le maualuga ma le mautu o le plasticity umi ma le malosi vevela. Pe a maualalo le vevela o le auaunaga nai lo le 620 ℃, o lona faʻatagaina faʻatagaina e maualuga atu nai lo le austenitic stainless steel. I luga aʻe o le 550 ℃, o le faʻamamafa faʻatagaina faʻatagaina fautuaina e tusa ma le faaluaina o le T9 ma le 2.25Cr-1Mo sila. E mafai ona faʻaaogaina e pei o le vevela vevela maualuga ma le paipa uamea mo le vevela puipui puipui ≤625 ℃, faʻauluulu vevela maualuga ma le vevela o le puipui paipa ≤600 ℃, faʻapea foʻi ma le faʻaulu afi faaniukilia ma le ogaumu o le afi taʻe suauu.
Fa'atatauga
E masani ona faʻaaogaina e fai ai paipa uʻamea uʻamea maualuga, paipa fesuiaʻi vevela, paipa ausa maualuga mo suauʻu ma pisinisi vailaʻau.
