ASTM A335 ndiyo yakajairwa dhizaini yeasina musono ferritic alloy-simbi mapaipi akagadzirirwa kukwirisa-tembiricha sevhisi. Inoshandiswa zvakanyanya mumaboilers, superheaters, heat exchangers, uye mamwe maapplication anoshanda pasi pepamusoro-tembiricha uye yakanyanya-kudzvanywa mamiriro. Pamusoro peGiredhi P22, mamwe akajairwa alloy mamakisi anosanganisiraP5 (UNS K41545), P9 (UNS K90941), P11 (UNS K11597),uyeP91 (UNS P90901).
Mugadziri uye Mamiriro
ASTM A335 P22 mapombi esimbi achagadzirwa nenzira isina musono uye ichave inopisa-yakapera kana kutonhora-inodhonzwa nekupedza kurapwa.
Mapaipi esimbi asina musonoari mapaipi asina welds, iyo inopa P22 simbi mapaipi ane kugadzikana kwepamusoro uye kuvimbika munzvimbo dzepamusoro-tembiricha uye yakakwirira-kudzvinyirira.
Kupisa Kurapa
P22 mapombi esimbi anozodziiswazve uye nekupiswa-kubatwa nekuzara annealing, isothermal annealing, kana normalizing uye kupisa.
