I whakaputaina: 31 o Ākuhata, 2026 | Kāwai: Ngā Pūrongo Hua · Ngā Otinga Ahumahi mō Rūhia
Kupu Whakataki
Kei te haere tonu te whakahoutanga me te whakawhānui i ngā rāngai whakaputa hiko, te whakamahine hinu me te matū hinu o Rūhia, e akiaki ana i te tono nui mō ngā pūnaha paipa koranu pāmahana teitei, pēhanga teitei. He maha ngā wā ka pāngia ngā paipa maitai waro ma e te rerekētanga ngoki me te korenga o te waikura i raro i ngā āhuatanga wera nui tonu, ā, ko te maitai koranu chromium-molybdenum (chrome-moly) te rauemi pai mō te ratonga pāmahana teitei nui.
ASTM A335ko te paerewa e mōhiotia ana i te ao mō ngā paipa maitai koranu chrome-moly ferritic korekore i hangaia mō te mahi pāmahana teitei me te pēhanga teitei. Hei kaihoko ngaio me te kaihokohoko e tohunga ana ki ngā otinga paipa ahumahi, kei te pupuri a SANONPIPE i tētahi rarangi whānui oNgā paipa ASTM A335i ngā reanga matua katoa, me ngā tuhinga tautoko katoa me ngā huarahi tuku kua arotauhia mō ngā kaupapa Rūhia. Ka āwhina mātou i ngā kiritaki ki te whiriwhiri i te reanga koranu tino pai kia rite ki ō rātou tikanga whakahaere, ā, ka whakaiti i ngā wā arahi hoko.
He aha te Paerewa ASTM A335?
ASTM A335 / ASME SA335Ko te paerewa tēnei mō ngā paipa maitai koranu ferritic kore hononga e whakamahia ana mō te mahi pāmahana teitei me te pēhanga teitei. E kapi ana i tētahi raupapa o ngā momo koranu kua whakapakaritia e ngā tāpiringa chromium me te molybdenum, e whakarato ana i te ātete ngoki, te ātete waikura me te kaha pāmahana teitei ki te whakataurite ki te maitai waro noa pēnei i teAPI 5L Tau B.
Me hanga ngā paipa katoa i raro i tēnei paerewa kia kore e hono te hanganga, ā, me whai i te maimoatanga wera whakahaere (te whakataurite + te whakamahana, te tinei rānei + te whakamahana mō ngā taumata koranu teitei) kia tutuki ai te hanganga moroiti ferritic e hiahiatia ana me ngā āhuatanga miihini pumau. He mea hanga ēnei mō te mahi roa i roto i ngā āhuatanga e kore e taea e te maitai waro te tu atu ki te ahotea wera tonu.
Ngā Tohu Matua me ngā Taurite GOST Rūhia
Kei a SANONPIPE ngā momo ASTM A335 e whakamahia whānuitia ana i te mākete Rūhia, kei ia momo he rite e whakaaetia whānuitia ana i raro i te paerewa ГОСТ 550 o Rūhia mō ngā paipa maitai koranu kore hononga. Ko ngā tohu o Rūhia kua tohua ki roto iRūhiakia māmā ake ai te tirotiro mā ngā miihini ā-rohe me ngā tīma hokohoko.
P11 (12X1MF)
Hei te taumata tīmatanga o te kōhua chrome-moly, kei roto i te P11 te 1.25% chromium me te 0.5% molybdenum. He pai te ātete ki te waikura tae atu ki te 550°C, ā, he kaha ngoki pono hoki mō te mahi pāmahana-waenga. Koinei te kōwhiringa tino whai hua mō ngā ngongo poiha, ngā pane mamaoa me ngā paipa āwhina i roto i ngā tipu hiko wera tuku iho.
P22 (10X2M / 15X2MF)
Ka whakapai ake a P22 i te ihirangi koranu ki te ~2.25% chromium me te 1% molybdenum, ka whakapiki ake i te pāmahana ratonga mōrahi ki te 595°C. Ka whakarato i te ātete whakaeke hauwai whakarei ake me te mahi ngokingoki pai ake, ka waiho hei rauemi paerewa-umanga mō ngā raina mamaoa matua, ngā pane whakamahana nui me ngā paipa tukatuka pāmahana-tiketike i roto i ngā whare hanga hinu me ngā tipu matū hinu.
P91 (10X9B2MF)
He koranu teitei te P91, he 9Cr-1Mo-V te kounga, he mea hanga mō te mahi pāmahana tino teitei tae atu ki te 620°C. Mā te tāpiri i te vanadium me te niobium hei whakapakari i te ua, ka nui ake te kaha pakaru o te ngoki, ā, koia te rauemi pai mō ngā paipa mamaoa matua o ngā tipu hiko tino nui me te tino nui, te wāhi e noho tahi ai te pēhanga nui me te pāmahana teitei.
Ngā Māka Tāpiri e Wātea ana
● P5 (15X5M / 12X5M)5% te karaehe chromium mō ngā ngongo whakamahana whakarewa ātete-whakapūkara
● P9 (10X9M / 15X9M)9% te karaehe chromium mō te ratonga whakapai chromium-tiketike me ngā whakamahana pāmahana-tiketike
