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 whakatikatika 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.
