Paipa maitai kore waikura kore-tuitui

Ko ngā paerewa paipa maitai kore waikura e whakamahia whānuitia ana ko:

E rima ngā paerewa: GB/T14976, GB13296, GB9948, GB6479, me GB5310. I roto i ēnei, e rua, e toru rānei ngā momo rauemi kowiri tira kua whakarārangihia i roto i ngā paerewa whakamutunga e toru, ā, ehara i te mea he momo rauemi e whakamahia whānuitia ana.

Nō reira, ko ngā paerewa GB/T14976 me GB13296 te nuinga o te wā e whakamahia ana ngā paipa maitai kore waikura i roto i te hangarau.

GB/T14976 “Paipa maitai kore waikura mō te kawe wai”:

Ngā momo rauemi: 304, 304L me ētahi atu momo 19 e tika ana mō te kawe wai whānui.

GB13296 “Ngā ngongo maitai kore waikura mō ngā poiha me ngā whakawhiti wera”:

Ngā māka rauemi: 304, 304L me ētahi atu momo 25.

I roto i ēnei, he tino pai te ātete waikura o te maitai kore waikura waro-iti rawa (304L, 316L). I raro i ētahi āhuatanga, ka taea te whakakapi i te maitai kore waikura pumau (321, 347) mō te ātete waikura ki ngā mea; he iti ngā āhuatanga miihini pāmahana teitei o te maitai kore waikura waro-iti rawa, ā, ko te tikanga ka whakamahia anake i ngā pāmahana i raro i te 525℃; he pai te ātete waikura me ngā āhuatanga miihini pāmahana teitei o te maitai kore waikura austenitic pumau, engari he ngāwari te waikura me te ngaro o te Ti i roto i te 321 i te wā e whakarewahia ana. Nō reira ka whakaitihia tana mahi ārai-waikura, ā, he nui te utu, ko tēnei momo rauemi e whakamahia whānuitia ana i ngā wā nui ake, ko te mahi ārai-waikura whānui o te 304, 316, ā, he iti te utu, nō reira he whānui te whakamahinga.
