SA213 fa'alava fa'auna maualugafaasologa o le afa'alava fa'auna maualugafa'asologa. Talafeagai mo faagaau u'amea ferritic ma austenitic e itiiti le mafiafia puipui mo boilers ma superheaters ma austenitic paipa uamea mo fesuiaiga vevela.

O paipa faʻavela o loʻo faʻaaogaina i pusa maualalo ma feololo (o le mamafa galue e masani lava e le sili atu i le 5.88Mpa, o le vevela galue e i lalo ole 450 ℃); fa'aaogaina i fala fa'alava maualuga (o le mamafa galue e masani lava i luga a'e o le 9.8Mpa, o le vevela galue i le va o le 450 ℃ ~ 650 ℃)) fa'avevela faagaau, superheaters, reheaters, petrochemical tubes, ma isi.

ASME SA213 T12u'amea paipa uamea, o le taitai i le tulaga American seamless paipa uamea, o loo faaaogaina lautele i suauu, alamanuia kemikolo, malosiaga eletise ma isi fanua alamanuia. O lenei ituaiga paipa uamea e faia i le sila maualuga. A maeʻa le faʻagaioiina ma le faʻaeteete i le tele o faʻagasologa, e maualuga le malosi ma maualuga le faʻafefe. E mafai ona faʻamalieina manaʻoga o le faʻaaogaina i siosiomaga faʻalavelave eseese.

O lona gaosiga faʻagasologa e faigata ma matagofie, e aofia ai le faʻafefeteina, taʻavale, tuʻia, ata malulu, togafitiga vevela ma isi fesoʻotaʻiga. I le taimi o le gaosiga o gaosiga, o le paipa uʻamea e maua ai le tele o mea sese ma suʻega e le faʻaleagaina e faʻamautinoa ai lona tulaga lelei ma le faʻamaoni. E iai foʻi suʻesuʻega vailaʻau eseese, suʻesuʻega metallographic ma isi suʻega e faʻamautinoa ai o lona tuʻufaʻatasiga, fausaga faʻalapotopotoga, faʻatinoga ma isi faʻailoga e fetaui ma tulaga manaʻomia.

O uiga oASME SA213 T12uamea paipa uamea e faapea:
1. Malosi maualuga: E maualuga le malosi ma le fua, ma e mafai ona tatalia avega tetele ma aʻafiaga.
2. Faʻasaʻo maualuga: E malosi le faʻafefeteina i siosiomaga faʻalavelave eseese, e pei o acids, alkalis, salts ma isi vailaʻau vailaʻau ma siosiomaga ogaoga e pei o le maualuga o le vevela ma le maualalo o le vevela.
3. Faʻataʻitaʻiga lelei o le uʻamea: Faia i le uʻamea maualuga, e le faʻafefeteina, pores ma isi faʻafitauli i le taimi o le uelo, faʻamautinoa le lelei ma le faʻamaoni.
4. Tele faʻaogaina o faʻaoga: E masani ona faʻaaogaina i le suauu, vailaʻau vailaʻau, eletise eletise ma isi faʻalapotopotoga faʻapisinisi, e pei o paipa suauu ma kesi, boilers, reactors ma isi meafaigaluega.
