Vaaiga lautele
"Faamaoni, Faʻafouina, Malosi, ma Lelei" e mafai ona avea ma faʻamatalaga faifaipea o la tatou faʻalapotopotoga, mo lena taimi umi i le fefaʻatauaʻiga, I le taimi nei, o le igoa o le kamupani o loʻo i ai le carbon steel ma Cr Mo Alloy Steel oloa ma maua ai faʻamaumauga maualuga ma sea tetele. i maketi i totonu ma fafo.
O se tasi o le faaaogaina o tatou paipa o galuega afi, e pei o le felauaiga o vai mo galuega afi, uaea eletise mo le afi wrk system ma isi.
Faamolemole ia matau, paipa u'amea ductile, paipa kopa, paipa u'amea, paipa tu'ufa'atasi, paipa uamea carbon, ma isi mea e masani ona fa'aaogaina mo paipa afi. Ole tele ole manaʻoga e ese mai paipa faʻapitoa ma e iai a latou lava manaʻoga faʻapitoa. O paipa fa'amumū e masani ona valiina ile vali mumu po'o le li'o mumu. Ina ia ese mai isi paipa.
I le faʻatinoga moni, o vaega eseese o le puipuiga o le afi e iai manaʻoga eseese mo ituaiga paipa ma meafaitino, e pei o: paipa i luga aʻe o paipa afi i totonu, pe a itiiti ifo pe tutusa le mamafa o le faiga i le 1.20MPa, paipa uʻamea uʻamea vevela. e mafai ona faʻaaogaina; Pe a sili atu le mamafa o galuega nai lo le 1.20MPa, e tatau ona faʻaaogaina paipa uʻamea faʻafefete faʻafefete poʻo paipa uʻamea faʻafefe; pe a sili atu le mamafa o le faiga o galuega nai lo le 1.60MPa, e tatau ona faʻaaogaina paipa uʻamea uʻamea vevela.
Fa'atatauga
Paipa u'amea e leai se mea mo le fa'aogaina o le vevela maualuga ASTM A106, talafeagai mo le vevela maualuga
Vasega Autu
