Ngā Pūrongo - I hainatia e Haina me Rūhia tētahi whakaaetanga mō te paipa hau maori Power of Siberia-2. I whakaatu a Royal Steel Group i tōna hiahia ki te tautoko katoa i te whanaketanga o te whenua.

I te marama o Hepetema, i hainatia e Haina me Rūhia tētahi whakaaetanga mō te paipa hau māori Power of Siberia-2. Ko te paipa, ka hangaia mā Mongolia, ko te whāinga he tuku hau māori mai i ngā mara hau o te taha hauauru o Rūhia ki Haina. Me te kaha tuku ā-tau kua whakaritea he 50 piriona mita pūtoru, e matapaetia ana ka whakahaerehia i te tau 2030 pea.

Ehara i te mea he paipa hiko noa iho te Power of Siberia-2; he taputapu rautaki hei whakahou i te ao whānui. Ka whakakore i te mana whakahaere pūngao o te Hauāuru, ka whakahōhonu ake i te mahi tahi rautaki i waenga i a Haina me Rūhia, ā, ka whakakaha ake i te oranga ōhanga ā-rohe. He tauira mahi anō hoki tēnei mō te mahi tahi toa-toa i roto i te ao maha-pokapū. Ahakoa ngā wero hangarau, ā-whenua, ā-taiao maha e pāngia ana e te uara rautaki o te kaupapa, ka hipa atu i ngā rohe arumoni, ka noho hei kaupapa nui hei whakatairanga i te hanganga o tētahi hapori me te heke mai tahi mō te tangata. E ai ki tā Putin i te hui hainatanga, "Ka herea e tēnei paipa ō tātou heke mai."

Hei kamupene hokohoko ki tāwāhi e tohunga ana ki ngā paipa hinu me te maitai motuhake, he nui te whai wāhi a Royal Steel Group ki te kaupapa paipa hau maori "Power of Siberia 2", me te tautoko hoki i te mahi tahi pūngao me ngā kaupapa here whanaketanga rohe i waenga i a Haina, Rūhia, me Mongolia.

E toru ngā paipa maitai waro nui te whānui, he mea whakapiripiri pango

Ka taea e Royal Steel Group te whakarato i ngā paipa maitai API 5L X80, API 5L X90, me te 3PE.

Ko te maitai X80 te paearu mō te maitai paipa kaha-teitei, e tutuki ana i te paerewa API 5L putanga 47. Ko te kaha tuku iti rawa o te 552 MPa, ko te kaha kume o te 621-827 MPa, me te ōwehenga tuku-ki-kaha o te 0.85, iti iho rānei. Ko ōna painga matua kei roto i te hoahoa mama, te pakari pai, me te kaha whakarewa kua whakapaitia.

Ko ngā tono noa ko:
Te Paipa Hau Taiao o Haina-Rūhia ki te RawhitiMā te whakamahi i te maitai X80 puta noa, ka tukuna e ia he 38 piriona mita pūtoru o te hau ia tau, ka whakawhiti hoki i ngā rohe hukapapa me ngā rohe rū whenua, ka whakatakoto i tētahi paearu ā-ao mō te hangarau hanga paipa o uta.

Kaupapa Paipa Hauāuru-Rawhiti IIINeke atu i te 80% o te whakamahinga katoa e whakamahia ana ngā paipa rino X80, e tautoko ana i te kawe pai o te hau māori mai i te taha hauauru o Haina ki te rohe o te awa o Yangtze.
Te whanaketanga o te hinu me te hau i roto i te wai hohonuI roto i te kaupapa mara hau Liwan 3-1 i te Moana Haina ki te Tonga, ka whakamahia ngā paipa maitai kore hononga X80 mō ngā paipa raro moana i ngā hohonutanga wai neke atu i te 1,500 mita, me te kaha pēhanga o waho o te 35 MPa.

Ko te maitai X90 te tuatoru o ngā whakatupuranga o ngā maitai paipa kaha-teitei, e tutuki ana i te paerewa API 5L putanga 47. Ko te kaha whakaputa iti rawa o te 621 MPa, ko te kaha kume o te 758-931 MPa, ā, ko te ōrite waro (Ceq) o te 0.47%, iti iho rānei. Ko ōna painga matua ko ngā rahui kaha teitei ake, te kaha whakarewa pakaru, me te urutau ki te pāmahana iti.

Ko ngā tauira tono noa ko:

Te Paipa Mana o Siberia 2Hei rauemi matua mō te kaupapa, ka kawe te paipa maitai X90 i te hau mai i ngā mara hau o Rūhia ki te Hauāuru o Siberia ki te Raki o Haina. Ina tīmatahia i te tau 2030, e matapaetia ana ka eke te nui o te tuku hau ā-tau ki te 20% o ngā kawemai hau katoa o ngā paipa o Haina.

Raina Paipa Hau Taiao o Āhia Waenganui DI ngā wāhi oneone tote rawa o te wāhanga Uzbek, ka roa ake te ora mahi o te paipa maitai X90, me te pūnaha tiaki katote 3PE +, ki te 50 tau.

Ko te paninga 3PE he paninga paura epoxy (FBE), he paparanga takawaenga piri, me te paninga polyethylene (PE), he matotoru katoa ≥2.8mm, e hanga ana i tētahi pūnaha tiaki hiato "pakari + ngāwari":

Ko te paparanga turanga FBE, he 60-100μm te matotoru, ka piri matū ki te mata o te paipa maitai, ka whakarato i te piri pai rawa atu (≥5MPa) me te ātete ki te wetewete cathodic (te radius kiri ≤8mm i te 65°C/48h).

Piripiri Waenga: 200-400μm te matotoru, he mea hanga ki te kapia EVA kua whakarerekētia, e piri ana ki te FBE me te PE, me te kaha tihore o te ≥50N/cm hei ārai i te wehenga i waenga i ngā paparanga.
PE o Waho: ≥2.5mm te matotoru, he mea hanga ki te polyethylene kiato-teitei (HDPE), me te pūwāhi whakangawari Vicat ≥110°C me te ātete ki te koroheketanga UV kua whakamātauhia e te whakamātautau rama xenon arc 336-hāora (te pupuri kaha kume ≥80%). He pai mō te whakamahi i roto i ngā whenua mania o Mongolia me ngā taiao permafrost.

Ko te kaupapa matua o te Royal Steel Group, "Te Auahatanga Rauemi e Arataki ana i te Huringa Pūngao," kei te whakarato tonu i ngā hua paipa maitai me ngā ratonga hangarau tino pono, tino whai hua hoki, mō te hanganga hanganga pūngao o te ao.
