Mō ngā pūnaha whakaputa hiko pāmahana teitei me te pēhanga teitei, ehara i te mea ko te whiriwhiri rauemi anake te whiriwhiri i tētahi paipa maitai kaha teitei.Paipa maitai kore-tuitui ASTM A335 P91kua whānuitia te whakaritenga mō te ratonga pāmahana teitei nā te mea he hononga tata tōna hoahoa koranu me te āhua maimoatanga wera ki te mahi miihini mō te wā roa.
Heoi, mō ngā kaihoko, ko te wero tūturu ko te kore e kimi i tētahi kaiwhakarato paipa P91. Ko te whakarite kiate māka, te maimoatanga wera, te tirotiro, te tuhi me te whai i ngā tuhingae tutuki katoa ana ki ngā whakaritenga o te kaupapa.
He aha aiASTM A335 P91 E whakamahia ana i roto i ngā pūnaha hiko pāmahana-tiketike?
ASTM A335 P91he paipa maitai-konumohe ferritic kore hononga i hangaia mō te mahi pāmahana teitei. E tohu ana a ASTM i te A335 hei whakatakotoranga e kapi ana i te paipa maitai-konumohe ferritic kore hononga mō ngā tono pāmahana teitei, me ngā whakaritenga e kapi ana i te hanganga matū, ngā āhuatanga miihini, te pakeke me te whakamātautau.
Kei roto i te P91 te 8–9.5% chromium me te 0.85–1.05% molybdenum, me ētahi atu tāpiringa whakahaere tae atu ki te vanadium, te niobium me te hauota. Ka tautokohia e tēnei hoahoa koranu te kaha me te ātete ngoki e hiahiatia ana mō ngā āhuatanga mahi uaua.
Ngā tono noa mōPaipa maitai koranu P91whakauru:
· Ngā pūnaha whakamahana wera me te mamaoa matua o te teihana hiko
· Ngā paipa mō te kohua me te whakamahana nui
· Ngā paipa mamaoa pāmahana teitei
· Ngā tipu hiko wahie pūmua me ngā tipu hiko huringa-whakakotahi
· Ngā paipa pēhanga pāmahana teitei me ngā taputapu e pā ana
Me whiriwhiri te kōeke tika i runga anō i te pāmahana hoahoa, te pēhanga, ngā tikanga ratonga me te waehere hangarau e tika ana, kaua i runga anō i te ingoa kōeke anake.
P91 vs P22He aha ngā kaihoko kāore e taea te whakaaro he whakakapinga ngāwari noa iho ēnei?
P91 me P22he pātai noa i roto i te hokohoko mai i ngā tipu hiko.
He rino Cr-Mo iti iho te koranu o te P22, engari he nui ake te ihirangi chromium o te P91, ā, he uaua ake te hoahoa koranu. Nō reira, he rerekē ngā āhuatanga rauemi me ngā tono kaupapa o ngā momo e rua.
Mō te hoko, ko te mea nui ko:
Kaua te P91 e whakakapia ki te P22—kaua rānei te P22 e whakakapia ki te P91—nā te mea he ōrite ngā ine.
Me whakauru atu ki te whakatairite tika:
· Te pāmahana me te pēhanga hoahoa
· Ngā whakaritenga mō te ngokingoki me te kaha mō te wā roa
· Te hanganga matū
· Āhua maimoatanga wera
· Ngā āhuatanga miihini
· Ngā whakaritenga tukanga whakarewa
· Ngā whakaritenga PWHT
· Ngā whakaritenga NDE me te tirotiro
· Ngā waehere hoahoa me te hanganga e tika ana
He mea tino nui tēnei ina hoko ana i ngā rauemi whakakapinga mō tētahi pūnaha hiko o nāianei.
P91 vs T91: He aha te whanaungatanga?
Ko tētahi atu rapunga auau koP91 me T91.
He tata te whanaungatanga o ngā tohu e rua i roto i te matū koranu, engari he rerekē ngā whakatakotoranga hua ASTM e pā ana ki a rāua.
ASTM A335 P91kua tohua mō te paipa maitai-konumohe ferritic kore hononga, i te meaASTM A213 T91kei raro i ngā whakaritenga mō ngā kohua maitai-konumohe ferritic me te austenitic, ngā ngongo whakamahana nui me ngā ngongo whakawhiti wera.
Nō reira, kaua te P91 me te T91 e whakaarohia he hua whakawhiti nā te mea he ōrite ō rāua tohu matū.
Me tirotirohia te āhua o te hua, ngā ine, ngā whakaritenga hanga, te tono me ngā whakatakotoranga kaupapa i mua i te whakakapinga.
He aha te Hiranga o te Maimoatanga Wera mō te P91
MōPaipa maitai kore-tuitui P91, ehara te maimoatanga wera i te mahi whakaputa tuarua. He wāhanga nui tēnei mō te whakatutuki i ngā āhuatanga rauemi e hiahiatia ana.
Nō reira, me mārama te tautuhi a te whakatakotoranga hoko P91 i ngā mea e hiahiatia ana:
· Āhua maimoatanga wera
· Ngā tuhinga maimoatanga wera
· Ngā hua whakamātautau ā-mīhini
· Ngā hua o te mārō
· Te hanganga matū
· Te tautuhi wera/rōpū
· Putanga paerewa e tika ana
E hiahiatia ana e te ASTM A335 kia tutuki te rauemi i ngā whakaritenga matū, kume me te pakeke kua tohua, ā, kei roto hoki i te paerewa ngā whakaritenga whakamātautau wai-pūmau me te kore-whakangaro.
Nā konei, me karo ngā kaihoko i te hoko P91 mai i tētahi whakatau utu e kī ana "ASTM A335 P91". He mea nui te whakatakotoranga hangarau katoa.
NDE me te Tirotiro: He aha ngā mea me tirotiro e ngā kaihoko?
He ponoTe tirotiro i ngā paipa P91me neke atu te kaupapa i te tirotiro tirohanga me te ine i ngā āhuatanga.
I runga anō i te whakatakotoranga o te kaupapa me ngā whakaritenga tāpiri e tika ana, me manatoko pea e ngā kaihoko:
· Tātaritanga matū
· Whakamātautau kume
· Whakamātautau mārō
· Te tirotiro i ngā āhuatanga
· Whakamātautau waipū
· Ngā whakaritenga NDE
· Ngā tuhinga maimoatanga wera
· Āhua o te mata
· Te tautuhi me te tohu rauemi
· Arotakenga a te hunga tuatoru, ina hiahiatia
E whakamārama ana te ASTM A335 i ngā whakaritenga whakamātautau wai-pūmau me te whakamātautau kore-whakangaro mō ngā paipa i tukuna ki te paerewa. Tērā pea ka tohua ētahi atu whakaritenga tirotiro i roto i te ota hoko.
Nō reira, me whakaū te tikanga NDE me ngā paearu whakaae ki te putanga e tika ana o te paerewa me ngā whakatakotoranga kaupapa.
MTC me te Aroturuki: He rite te hiranga o ngā tuhinga ki te paipa
Mō ngā kaupapa o ngā tipu hiko,P91 MTCmete whai i ngā rauemihe mea nui ngā whakaaro hoko.
Me hono pea tētahi kete rauemi tika:
Tau Wera → Paipa → Maimoatanga Wera → Ngā Hua Whakamātautau → MTC → Ngā Rekoata Tirotiro
Me tirotiro e ngā kaihoko mēnāTiwhikete Whakamātautau Rauemi (MTC)e whakaatu mārama ana i te taumata o te rauemi, te tau wera, te hanganga matū, ngā āhuatanga hangarau, ngā mōhiohio maimoatanga wera me ngā hua whakamātautau e hiahiatia ana.
Mō ngā kaupapa EPC nunui, ka taea e ngā raruraru whaiwhai te whakaroa i te wā whakaae rauemi, te hanga, te arotake tuhinga whakamutunga rānei—ahakoa te āhua e tika ana te paipa tūturu.
Me Whakaū te Whakarewa me te PWHT i mua i te Tono
He maha ngā wā ka whakamahia te P91 i roto i ngā pūnaha paipa pāmahana-tiketike kua whakarewaina, nō reiraP91 whakarewamePWHTme whai whakaaro ki tēnei i te wā o te hokonga mai, kaua i muri i te taenga mai o te paipa.
Me whakatū te tukanga whakarewa, te whakamahana i mua, te whakahaere i waenga i ngā ara, te maimoatanga wera i muri i te whakarewatanga me ngā whakaritenga tirotiro e pā ana, kia rite ki ngā whakaritenga kaupapa e tika ana, te tohu tukanga whakarewa me ngā waehere whakahaere.
Nō reira, me whakarato te kaihoko ki te kaiwhakarato ngā whakaritenga kaupapa e tika ana i mua i te whakaputanga i ngā wā katoa e taea ai.
Mā tēnei ka āwhina kia mōhio kei te tautoko ngā rauemi me ngā tuhinga kua tukuna i te tukanga hanga me te tāutanga o muri.
He aha te take e kore ai te hoko P91 e whakawhirinaki ki te utu anake
Ehara i te mea ko te utu iti rawa te utu iti rawa mō te kaupapa.
MōPaipa maitai koranu P91, ko ngā mōrearea hokohoko pea ko:
· He hē te māka, te whakatakotoranga rānei
· Ngā tuhinga mō te maimoatanga wera kāore i oti
· Te ngaro o te whai i ngā mea
· MTC kāore e tutuki ana i ngā whakaritenga
· Kāore i te rawaka ngā tuhinga NDE
· Te whakaroa i te tirotiro a te hunga tuatoru
· Ngā uauatanga i te wā e whakaaetia ana ngā rauemi a te kiritaki
· Ngā raruraru tuhinga i te wā e tukuna ana te kaupapa
Mō ngā kaupapa hiko me ngā kaupapa ahumahi he nui te uara, ka nui ake ngā utu i te rerekētanga tīmatanga o te utu paipa nā ēnei take.
Ko te huarahi hoko pai ake ko te aromatawaite tutuki i ngā whakaritenga rauemi + te tirotiro + te tuhi tuhinga + te whai i ngā whakaritenga + te āheinga tukutahi.

Whakamutunga Whakamutunga
Paipa maitai kore-tuitui ASTM A335 P91he rauemi tino mahi mō ngā tono paipa mana pāmahana tiketike me te pēhanga nui, engari ko te angitu o te hoko ehara i te mea ko te tohu tohu anake.
Mō ngā kaupapa P91, me arotake e ngā kaihoko te mekameka tuku katoa—mai ite whiriwhiri rauemi me te maimoatanga wera kia rite ki te tirotiro, te MTC, te whai i ngā whakaritenga whakarewa me te tuku.
Mō ngā kaupapa he mea nui te tutuki i ngā whakaritenga me te tuhi tuhinga, mā te mahi tahi me tētahi kaiwhakarato e kaha ana ki te whakarite i ngā whakaritenga hangarau me te whakatinanatanga o ngā tuku ka taea te whakaiti i te mōrearea hoko.
E tautoko ana a SANONPIPE i te kohikohinga P91 me te whakaū i te tohu, te whakarite tirotiro, te whai i ngā otinga me te tuku mō ngā kaupapa whakaputa hiko me ngā kaupapa ahumahi pāmahana teitei.
