A335 P92(e rite ana ki te paerewa Hainamana 10Cr9MoW2VNbBN) he maitai ātete wera martensitic o te whakatupuranga e whai ake nei i whakawhanakehia mai iP91Mā te tāpiri i te tungsten (W) ki te 9% te maitai chromium me te whakanui ake i te ōrite o te molybdenum (Mo+0.5W) mai i te 1% i roto i te P91 ki te 1.5%, kua tino whakarei ake te mahi pāmahana teitei o te rauemi.

Ko ngā wāhi tono matua ko:

Te Whakaputa Hiko Wera Tino-tino-tino: Ko te P92 te rauemi matua mō ngā paipa mamaoa matua me te whakamahana anō i ngā paipa mamaoa i roto i ngā waeine tino-tino-tino-tino-akomanga 1000MW, me te pāmahana mahi hoahoa mōrahi o te 625°C. I te 600°C, ka eke te ahotea hoahoa whakaaetia ki te 128MPa, ā, ka eke te kaha ngoki pāmahana teitei ki te 128MPa≥100MPa. Ko tōna kaha pakaru ngoki pāmahana teitei he tata ki te 30% teitei ake i te P91, me te kotahi miriona-kirowati e kai ana i te 800 tāne.

Ngā Wāhanga Matua o te Pūwero: E whakamahia whānuitia ana i roto i ngā pane pūwero, ngā whakamahana nui, ngā whakamahana anō, me ētahi atu wāhanga pēhanga. Ko tētahi o ngā momo maitai pai rawa atu mō te hanga taputapu tipu hiko wera nui i roto i te motu me te ao.

Ahumahi Matūriki: Whakamahia i roto i ngā paipa tauhohenga hauwai, ngā ngongo oumu pakaru, me ētahi atu pūnaha pāmahana teitei me te pēhanga teitei.

Mana Karihi: Ka whakamahia hoki i roto i ngā pūnaha paipa taha tuarua o ngā tipu mana karihi o te whakatupuranga tuatoru pērā i te AP1000.

Ki te whakatauritea ki ngā maitai kore waikura austenitic, he pai ngā painga o te P92 tae atu ki te ātete kaha ki te waikura, te kawe wera nui, me te tauwehenga whakawhānui wera iti.

II. Ngā Mira Rino ā-Rohe me ngā Painga Whakataetae

He wero te whanaketanga o te maitai P92, e hiahia ana kia tino teitei ngā paerewa mō te hoahoa tukanga me te whakahaere whakaputa. I tēnei wā, he iti noa iho ngā mira maitai o te motu kua tutuki i a rātou te kaha whakaputa pumau.

1. Rōpū Beizhong—Kaiārahi Wāhanga Mākete

Neke atu i te 80% o te hea mākete o Beizhong Group i roto i te rāngai paipa maitai P92 o te motu. E 28 ngā tohu tirotiro kua paahitia e āna hua, ā, kua toa āna whakatutukitanga hangarau i te Tohu Tuatahi o te Auahatanga Pūtaiao me te Hangarau Hiko Hiko o Haina. Kua tutuki i te rōpū te kapinga whānui mai iΦ89 ki teΦ813, me ngā rekoata hangarau whānui mō te whakarato i ngā paipa nui e whā mō ngā waeine tino-tino-kino.

2. Roopu Yonggang—Ngā Painga i roto i te Hanga Pire

I angitu te whakamātautau a te Yonggang Group i te SA335 P92 i te tau 2017, ā, kei a rātou inaianei te kaha ki te whakaputa i ngā pire porowhita whakarewa tonu i roto i ngā whakatakotoranga mai iφ380mm kiφ800mm, e hoatu ana ki a ia he painga whakataetae i roto i te mākete pereki rahi-rahi o te motu. Ko ngā hua pereki porowhita nui P91, P92, me ētahi atu hua pereki porowhita nui-konumohe a te kamupene kei te pupuri i te tūranga matua i roto i te mākete Haina. Hei tāpiri, kua tohua hei wheketere whakaaturanga hanga atamai taumata-motu, e whakapai tonu ana i te whakahaere kounga hua me te arotau utu.

3. Ngā Taputapu Nuclear o Hebei Hongrun—Ngā Taputapu me ngā Tukanga Ahurei

Ka whakamahia e Hongrun Nuclear Equipment tētahi mīhini tānga poutū 50,000-tana hei whakaputa i ngā paipa maitai kore hononga P92 nui te whānui. I te mahi tahi me Baowu Special Steel, ka whakamahia e ia ngā poro maitai kounga teitei, ka hua ake he hua he hanganga matotoru me te mahi tino pai. Kua paahitia e āna paipa maitai P92 te tiwhikete hua mai i te National Power Equipment Center, ā, kua tutuki katoa ngā tohu mahi i ngā whakaritenga paerewa GB/T 5310 me ASME SA335.

4. Ētahi atu Kaihanga

Kua tutuki hoki i a Baosteel Special Steel, Tianguan Group, Xinxing Ductile Iron, me ētahi atu umanga te whakamana i te whakaputanga papatipu o ngā hua e pā ana ki te P92, e whakatairanga ana i te tukanga rapunga o tēnei rauemi.

III. Ngā Painga Whakataetae Whānui

Ko ngā painga whakataetae o ngā mira maitai ā-rohe i roto i ngā hua P92 e whakaatahia ana i roto i: tuatahi, he tino whakaiti i ngā utu hoko mā te whakakapinga kawemai; tuarua, he whakapai ake i te pumau o te kounga hua i akiakihia e te panonitanga atamai me te mamati (hei tauira, i eke te kaupapa wheketere atamai a Yonggang ki te pikinga o te pai o te whakaputanga neke atu i te 12% me te whakahekenga o te reiti hapa 15.7%) me te tuatoru, he whanaketanga tonu i roto i ngā whakatakotoranga teitei pēnei i ngā paipa whānui me ngā pakitara matotoru, me te whakaiti haere i te whakawhirinaki ki ngā kawemai.
