Whakarōpūtanga rauemi
He maha ngā momo rauemi kei roto i te ASTM A333/A333M, ā, he rerekē te hanganga matū o ia momo:
1. Wāhanga 1
Waro (C): ≤0.30%
Manganēhi (Mn): 0.40-1.06%
Whēkau (P): ≤0.025%
Whānariki (S): ≤0.025%
Hiraka (Si): ≥0.10%
2. Wāhanga 3
Ko te ihirangi nikara (Ni) he tata ki te 3.5%, ā, he pai ake te pakari i te pāmahana iti
3. Wāhanga 6
Waro (C): ≤0.30%
Manganēhi (Mn): 0.29-1.06%
Whēkau (P): ≤0.025%
Whānariki (S): ≤0.025%
Hiraka (Si): ≥0.10%
4. Wāhanga 8
Rauemi kowiri tira Austenitic, ko te tikanga he 304, he 304L rānei
5. Wāhanga 9
Ko te nui o te nikara (Ni) he tata ki te 1.5%, i waenga i te Gr.3 me te Gr.6
6. Wāhanga 10
He rino koranu iti kei roto ko te molybdenum (Mo) hei whakapai ake i te ātete ki te waikura
Te whānuitanga pāmahana e tika ana mō ia taumata
| Tau | Te pāmahana whakahaere iti rawa |
| Wāhanga 1 | -45℃ |
| Wāhanga 3 | -100℃ |
| Wāhanga 4 | -110℃ |
| Wāhanga 6 | -45℃ |
| Wāhanga 7 | -100℃ |
| Wāhanga 8 | -195℃ |
| Wāhanga 9 | -110℃ |
| Wāhanga 10 | -75℃ |
Whakamārama tāpiri
1. Ko te Gr.6 te momo e whakamahia whānuitia ana, he tino pai mō ngā taiao pāmahana iti pēnei i te LNG (-162℃)
2. Ko te kōwhiringa o ngā momo tohu rerekē e whakawhirinaki ana ki te pāmahana hoahoa, ngā āhuatanga reo me ngā whakaaro utu
3. Ka whakamātauhia ngā momo paipa rino katoa ki te pāmahana iti hei whakamana i tō rātou pakari.
4. Mō ngā paipa maitai kua whakarewaina, me whai maimoatanga wera tika i muri i te whakarewatanga hei whakaora i ngā āhuatanga o te rauemi.
5. I te wā e hoko ana, me whiriwhiri te taumata rauemi e tika ana kia rite ki te taiao tono motuhake, ā, me tino manatoko te tiwhikete rauemi me te pūrongo whakamātautau.
