O paipa u'amea mo fugala'au vaila'au e masani lava ona fa'aaogaina e gaosia ai le u'amea sili ona lelei, uamea fa'ameamea ma le uamea fa'afefeteina o le vevela maualuga le fa'aogaina o paipa fa'afu ausa ma le maualuga maualuga ma luga a'e o paipa ma o nei paipa fa'afu e galue i lalo ole vevela maualuga. ma le maualuga o le mamafa, ma o le a oxidized tubes ma corroded i lalo o le gaioiga o le vevela maualuga kasa flue ma ausa.O le mea lea, o paipa uʻamea e manaʻomia e maua ai le malosi tumau maualuga, maualuga le faʻamaʻiina o le faʻamaʻiina, ma le faʻamautuina lelei o le faʻalapotopotoga.O togi u'amea o lo'o fa'aogaina e: maualuga maualuga carbon structural sila togi o 20G, 20MnG, 25MnG;Alloy fausaga uamea togi 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, ma isi;Ole masani ole 1Cr18Ni9 ma le 1Cr18Ni11Nb faʻapipiʻi faʻapipiʻi maualuga e faia i le uʻamea ma le vevela vevela e tatau ona faʻataʻitaʻiina i suʻega hydrostatic, faʻamalama ma faʻamafola faʻataʻitaʻi tasi i le faʻaopoopoga i le faʻamautinoaina o le vailaʻau ma mea faʻainisinia.O paipa uʻamea faʻapitoa mo vailaʻau vailaʻau e tatau ona tuʻuina atu i le tulaga vevela vevela.

Siosiomaga talafeagai

O le paipa faʻapitoa mo le faʻamaʻi (GB6479-2000) o se uamea faʻapipiʻi maualuga carbon ma faʻameamea uamea seamless paipa uamea talafeagai mo meafaigaluega vailaʻau ma paipa ma le vevela galue o le - 40 ~ 400 ℃ ma le mamafa galue o le 10 ~ 30Ma.

Pipa u'amea maualuga maualuga mo mea fa'afuifui (GB6479-2000) o se u'amea fausaga maualuga carbon ma u'amea uamea seamless paipa uamea talafeagai mo meafaigaluega vailaau ma paipa ma le vevela galue o - 40 ~ 400 ℃ ma le mamafa galue o le 10 ~ 30Ma.

Fa'atomuaga o gaosiga

(1) Gaosi auala:

①O le vevela o le faʻaogaina o paipa uʻamea mo le faʻamaʻi e i lalo ifo o le 450 ℃, ma o paipa fale e masani lava ona faia i paipa uʻamea vevela poʻo le malulu 10 # ma le 20 # carbon bonded paipa.

②O le paipa uʻamea faʻapitoa mo faʻamaʻi e masani ona faʻaaogaina i lalo o le maualuga o le vevela ma le maualuga o le mamafa, ma o le paipa o le a faʻamaʻiina ma pala i lalo o le gaioiga o le vevela vevela ma le vai vai.O le paipa uʻamea e manaʻomia e maua ai le malosi tumau maualuga, maualuga le faʻamaʻiina ma le faʻafefeteina, ma le faʻamautuina lelei o le faʻalapotopotoga.

(2) Faamoemoega:

①O paipa uʻamea mo faʻamaʻi vailaʻau e masani ona faʻaaogaina e gaosia ai paipa vai puipui, paipa vai faʻafefe, paipa ausa faʻavevela, paipa ausa faʻavevela mo locomotive boilers, paipa asu tetele ma laiti ma paipa piliki.

②O le paipa uʻamea faʻapitoa e faʻaaogaina mo le faʻamaʻi e masani ona faʻaaogaina e gaosia ai paipa sili, paipa faʻavevela, paipa ea, paipa ausa, ma isi mea faʻapipiʻi maualuga ma maualuga maualuga.
