Hakihea 2025 - Ngā Whanaketanga Matua o te Ahumahi me ngā Whakahōutanga Kaupapahere
I te mutunga o te tau 2025, ka tūtaki te mākete paipa maitai kore hononga o te ao ki tētahi wā hurihanga nui me ngā kaupapa here raihana kaweake hou e tumanakohia ana mai i ngā mana whakahaere Haina. E tohu ana ngā kaitātari mākete mā ēnei ture, ka whai mana pea i te tīmatanga o te tau 2026, ka hiahiatia he tuhinga whakarei ake mō ngā kaweake paipa maitai waro, paipa maitai koranu, me ngā paipa maitai kore hononga. Ko te whāinga o te kaupapa here he whakarite i te mana kounga puta noa i teAPI 5L, ASTM A106, ASTM A335 P11/P22, me ngā kāwai hua ASTM A312 TP304/TP316L, me te aro atu ki ngā āwangawanga tauhokohoko o te ao.
Ngā Āhuatanga o te Mākete o Hakihea me ngā Auahatanga o te Mutunga o te Tau
Ko ngā āhuatanga o te mākete o nāianei e whakaatu ana i te pumau i muri i ngā whakarerekētanga o Noema, me te hekenga o ngā taonga paipa kore-whakawhiti tata ki te 8.2% i roto i ngā pokapū whakaputa nui o Haina. Kei te pupuri tonu te rāngai paipa hinu me te hau i te tono pumau mō ngā paipa raina me ngā hua OCTG, i te mea kei te haere tonu ngā kaupapa whakaputa hiko ki te rapu i ngā ngongo poiha pēhanga teitei me ngā ngongo whakawhiti wera. Heoi, e ai ki ngā kaiwhakahaere hoko he roa ake ngā wā arahi o te 50-65 rā mō ngā paipa kore-whakawhiti whānui me ngā paipa maitai koranu motuhake i te mea e whakaoti ana ngā mira i ngā ota o nāianei i mua i ngā huringa kaupapa here pea.

Whakamutunga: Te Whakamahere Matatau mō ngā Whakawhitinga Mākete
Ko te whakatinanatanga o te raihana kaweake e tumanakohia ana e whakaatu ana i ngā whakaritenga ture me ngā whai wāhitanga manatoko kounga mō te hoko paipa maitai. Mā te whakatū i ngā mahi tuhinga mārama me te whakapakari i ngā whanaungatanga kaiwhakarato inaianei, ka taea e ngā kaihoko o te ao te whakahaere tika i te whakawhiti kaupapa here me te whakarite i ngā taonga pono o ngā paipa maitai kore hononga, ngā ngongo maitai waro, me ngā paipa koranu motuhake mō ngā kaupapa o te tau 2026.
Whakapā mai ki tā mātou tīma hokohoko o te ao mō ngā tātaritanga ritenga mō te pānga o ēnei whanaketanga ki ō hiahia motuhake mō ngā paipa tuimotu, ngā paipa whakarewa, me ngā hua ngongo. Ka whakaratohia e mātou ngā whakahoutanga mākete, te whakamārama kaupapa here, me te whakawhanake rautaki hoko mō ngā paipa hinu me te hau, ngā pūnaha whakaputa hiko, me ngā tono ahumahi.
ASTM A106 Gr.BKo te paipa maitai tuitui he paipa maitai waro pāmahana-teitei i roto i te paerewa a te American Society for Testing and Materials, e whakamahia ana mō te kawe wai i raro i te taiao pāmahana teitei me te pēhanga teitei. Ko ngā rauemi e pā ana ki Haina e pā ana ki te paerewa ā-motu Haina (GB) me ngā paerewa ahumahi, ā, me whakataurite mai i ngā tirohanga e toru: te hanganga matū, ngā āhuatanga miihini, me ngā horopaki whakamahinga.
E rua ngā kōwhiringa mō te whakataurite i ngā rauemi o te whare:
Ko te rauemi tuatahi e rite ana: 20 maitai (GB/T 8163)
Ko te maitai 20 he maitai hanganga waro noa, he rauemi noa i roto i te paerewa GB/T8163, ā, he pai mō te kawe wai whānui. Te whakataurite i te hanganga matū: Ko te ihirangi waro (C) o te ASTM A106 Gr.B he 0.17-0.24%, me te konupūmā (Mn) he 0.29-1.06%; ko te ihirangi waro o te maitai 20 he 0.17-0.24%, me te ihirangi konupūmā he 0.35-0.65%. He tata te ihirangi waro o ngā mea e rua, engari ko te ihirangi konupūmā o te ASTM.A106 Gr.Bhe teitei ake te rohe o runga, ā, he pai ake te mahi pāmahana teitei.
Te whakatairite i ngā āhuatanga miihini: Ko te kaha kume o te ASTM A106 Gr.B he >415MPa me te kaha tuku he >240MPa; ko te kaha kume o te maitai 20 he >410MPa me te kaha tuku he >245MPa. He rite ngā raraunga engari he rerekē ngā pāmahana e tika ana.
Ngā herenga whakamahinga: He pai te maitai 20 mō ngā āhuatanga mahi me te pāmahana hoahoa i raro i te 350℃ me te pēhanga iti. Mena ka whakamahia mō te pāmahana teitei me te pēhanga teitei (pērā i ngā paipa poihau), me whiriwhiri he rauemi paerewa teitei ake.
Ko te rauemi tuarua e rite ana: 20G (GB 5310)
He rauemi paipa maitai tuimotu te 20G mō ngā kohua pēhanga-teitei, nō te paerewa GB 5310, ā, he pai mō ngā pūnaha mamaoa pāmahana-teitei me te pēhanga-teitei.
Te whakataurite i te hanganga matū:20Ghe ihirangi waro kei roto i te 0.17-0.24%, he ihirangi manganese kei roto i te 0.35-0.65%, ā, he kaha ake te whakahaere i te ihirangi phosphorus me te whanariki, e rite ana ki ngā tohu o te ASTMA106 Gr.B.
Te whakataurite i ngā āhuatanga miihini: Ko te kaha kume o te 20G he ≥410MPa, ā, ko tōna kaha whakaputa he >245MPa, he tata rite ki te ASTM A106 Gr.B, ā, ko te pāmahana whakahaere e whakaaetia ana he tae atu ki te 450℃.
Ngā horopaki tono: E whakamahia whānuitia ana te 20G i roto i ngā paipa pūwero o ngā tipu hiko wera me ngā taputapu matū pēhanga teitei, ā, ka taea te whakakapi i te ASTM A106 Gr.B mō ngā āhuatanga mahi ōrite.
Ngā Whakatūpato Whakakapinga 1. Ngā Rerekētanga Paerewa: Ko te ASTM A106 Gr.B e hiahia ana ki te whakamātautau kume whakawhiti me te whakamātautau papatahi, ko te GB/T 8163 ia e hiahia ana ki te whakamātautau kume roa anake. I te wā e whakakapia ana, me whakaū mēnā ka tutuki ngā tūemi whakamātautau i ngā whakaritenga.
2. Ngā whakaritenga maimoatanga wera: Ko te ASTM A106 Gr.B ka tukuna i te nuinga o te wā i roto i te āhua hurihuri wera, me whakarite te maimoatanga 20G, ā, me whakarerekē te tukanga mēnā ka whakakapia.
3. Ngā whakaritenga tiwhikete: Mena ka tohua e te kaupapa kaweake te rauemi paerewa o Amerika, me whakaū ki te kiritaki mēnā ka whakaaetia te whakakapinga paerewa ā-motu. Tērā pea ka hiahiatia he tirotiro tāpiri mai i ētahi atu rōpū mō ētahi kaupapa.
Tauira tono whai hua
I hokona e tētahi umanga matū hinu ngā paipa ASTM A106 Gr.B mō te kawe hinu pāmahana teitei. Nā te roa o te huringa tuku, i huri ki te rauemi 20G. Whai muri i te whakamātautau a te hunga tuatoru, i tutuki i te pakari pānga (-20℃ KV2234J) me te kaha pāmahana teitei (kaha hua>180MPa i te 450℃) o te 20G ngā whakaritenga hoahoa, ā, i whakaaetia te kaupapa.
Whakarāpopototanga
Ka taea e te ASTM A106 Gr.B te hanga i te maitai 20 (ngā tikanga mahi whānui) me te 20G rānei (ngā tikanga mahi pāmahana teitei me te pēhanga teitei) i Haina. I te wā e whakakapia ana, me whakakotahi ngā paerewa pāmahana, pēhanga me te whakamātautau motuhake. E taunakihia ana kia aro nui ki te rauemi 20G, ko tōna hanganga matū me te mahi he tata ake ki ngā whakaritenga paerewa o Amerika, ā, he whānui ake ngā tono.
