Mena kei te hiahia koe ki te mōhio atu ki ētahi atu kōrero, pēnei i te whakatau utu, ngā hua, ngā otinga, me ētahi atu, prīhiwhakapā mai ki a mātou i runga ipurangi.
He toa hokohoko a Tianjin Sanon Steel Pipe Co., Ltd. Kei te Tāone o Cangzhou, Porowini o Hebei tō mātou wheketere. Ko ā mātou puna matua o ngā taonga kongā paipa kōhua, ā, ko ngā rauemi e whakaatu ana i tēnei koASTM A335 P5/P11/P91/P92,ASME SA-106/SA-106MGR.B,GB/T 3087-200810#/20#. Ko ngā rauemi matua mō ngā paipa paipa koAPI 5L,API 5CT, ngā rauemi matua mō ngā paipa pakaru hinuGB/T 9948he 15MoG/12CrMoVGKo te GB/T 6479-2013 e tohu ana i ngā rauemi 10#/20#, ngā ngongo whakawhiti wera SA179/SA210/SA192, me ētahi atu. Ko ngā ngongo miihini GB/T 8162 e tohu ana i ngā rauemi 10#/20#/Q345/42CrMo, ko te EN10210 e tohu ana i ngā rauemi S355JOH/S355J2H, ko ngā ngongo rango hau GB1 8248 e tohu ana i ngā rauemi 34CrMo4/30CrMo.
I roto i ngā mara o te whakaputa hiko wera me te tukatuka matū hinu, i reira ko ngā pāmahana teitei me ngā pēhanga teitei te tikanga, he rauemi nui te maitai koranu A335 P91. He whānuitia te whakamahinga i roto i ngā raina mamaoa matua me te whakamahana anō i ngā wāhanga wera nā te mea he kaha pāmahana teitei, he ātete ki te ngoki, me te ātete ki te waikura. Heoi, ka ara ake tētahi pātai noa i te wā e hoko mai ana, e whakamahi ana rānei: He aha te rerekētanga i waenga i te Momo 1 me te Momo 2? Ka whakaratohia e tēnei tuhinga he whakamārama taipitopito.
Rerekētanga Matua: Tukanga Hanga me te Hanganga Moroiti
Ngā whakaritenga hanganga matū mōA335 P91e tautuhia ana e te paerewa ASTM A335 tonu. Kāore te whakarōpūtanga o te Momo 1 me te Momo 2 i ahu mai i te ASTM A335, engari i ahu mai i tētahi atu paerewa tautoko nui: ASTM A213 (Whakatakotoranga Paerewa mō te maitai Ferritic me te Austenitic Konumohe mō te Boiler, Superheater, me ngā ngongo whakawhiti wera).
Ko te rerekētanga matua i waenga i ngā momo e rua kei roto i te tukanga maimoatanga wera whakamutunga o te hanga, ka hua tika mai ai he rerekētanga i roto i ō rātou hanganga moroiti.
Ka pāngia e te Whakaōrite me te Whakamahana. Ka whakaōritea te paipa ki runga ake i te pāmahana whakaausteniti, kātahi ka whakamāhanatia ki te pāmahana teitei.
Hanganga Moroiti: Ka tutuki i a ia tētahi hanganga martensite kua tino whakapakeketia. Koinei te āhua matarohia me te āhua noa mō te maitai P91, e tuku ana i te huinga whānui pai rawa atu o ngā āhuatanga ā-pūkaha.
Ka whakamahanahia te paipa i te pāmahana kei raro iho i te Ac1 (te pāmahana tino iti).
Hanganga Moroiti: Ko tōna hanganga he mea hanga mai i te ferrite kua whakamahanatia me ngā carbide. Kāore e pāngia e te tukanga whakataurite katoa hei hanga martensite.
He aha te take i noho ai te Momo 2?
Ko te pūtake o te tukanga Momo 2 he whakatutuki i ngā āheinga ā-ahu tino kikī.
Ka taea e te tukanga Whakaōrite + Whakamahana te whakapōturi i te āhua o te paipa, te whakarerekē rānei i te āhua porowhita, ka raru pea tēnei mō ngā tono e hiahiatia ana he tino tika.
•Ka mahia te whakamahana i raro i te hiranga i te pāmahana iti iho, ā, he tukanga ngāwari ake, e pai ake ai te pupuri i te āhua me ngā rahi tika o te paipa i muri i te mahi matao.
Ngā Rerekētanga Mahi me te Whakatūpato Hira
Ko te rerekētanga tino nui kei roto i ngā āhuatanga hangarau, inā koa te kaha ki te pāmahana tiketike.
•Momo 1 (N&T): Kei a ia te kaha katoa me te kaha ngoki teitei e hiahiatia ana e te whakatakotoranga paerewa. Koinei te tikanga pai me te paerewa mō te hoahoa me te tono.
•Momo 2 (Kua whakawerahia): He iti iho tōna kaha i te Momo 1. Kāore e taea e tōna kaha pāmahana teitei me ōna āhuatanga ngokingoki te whakatutuki i te ngā whakaritenga mō te rauemi P91 e ai ki te paerewa ASTM A335.
Nō reira, KAUA rawa e whakamahia tika te rauemi Momo 2 mō te ratonga pāmahana/pēhanga teitei! Mena ka hokona ngā paipa i roto i te āhua whakamahana iti (Momo 2), ME mahi te kaihanga, te kaiwhakamahi rānei i te maimoatanga wera whakataurite me te whakamahana katoa ki runga i a rātou i mua i te tāutanga whakamutunga. Mā tēnei ka hurihia tō rātou hanganga iti hei martensite kua whakamahana katoatia (arā, ka hurihia ki te āhua Momo 1), ā, ka tutuki ai ngā āhuatanga miihini e hiahiatia ana.
Ripanga Whakataurite Whakarāpopototanga
I roto i ngā kupu māmā noa iho, ko te Momo A335 P91 2 he āhua "haurua-oti", e whakakore ana i ngā āhuatanga kaha katoa mō te ngāwari o te hanga me ngā rahi kua oti te whakarite. I tētahi atu taha, ko te Momo 1 te āhua "hua kua oti", kei a ia ngā āhuatanga katoa e tika ana hei whakahaere i ngā taiao pāmahana teitei me te pēhanga teitei.
I te wā e hoko mai ana, e tirotirohia ana hoki, he mea nui kia tohua te āhua e hiahiatia ana e koe, me te manatoko hoki i ngā mōhiohio maimoatanga wera i runga i ngā tiwhikete rauemi. Ko te whakarite kia tika te hanganga me ngā āhuatanga o ngā paipa kua tāutahia, he mea nui tēnei hei whakapūmau i te haumaru me te pono o te mahi a ngā tipu hiko me ngā whare ahumahi.
