    Ko ta tatou whanaketanga e whakawhirinaki ana ki nga taputapu matatau, nga taranata tino pai me te kaha tonu o te kaha hangarau mo to tatou paipa maitai o te ahumahi kounga teitei, Ka kaha tonu tatou ki te whakanui ake i ta tatou kamupene me te whakarato i nga hua kounga pai me nga awhe utu utu. Ko nga patai me nga korero ka tino maioha. Kia mahara ki te pupuri noa i a matou. Ko ta tatou kamupene kei te mahi i runga i te kaupapa whakahaere o "te tapatahi, te mahi tahi i hangaia, te tangata e aro ana, te toa-win te mahi tahi". Te ti'aturi nei matou ka taea e matou te whai hononga hoa ki nga kaipakihi mai i nga wa katoa o te ao

    Ko te P91 ehara i te mea he nui te aukati o te waikura me te wera nui o te korowha korowha, engari he pai hoki te kaha o te paanga me te teitei me te pumau o te kirihou roa me te kaha wera. Ina he iti ake te mahana o te ratonga i te 620 ℃, ka nui ake te ahotea o te kowiri tira austenitic. I runga ake i te 550 ℃, ko te ahotea e whakaaetia ana mo te hoahoa he tata ki te rua o te T9 me te maitai 2.25Cr-1Mo. Ka taea te whakamahi hei whakamahana teitei o te wera me te putorino rino mo te subcritical me te supercritical kohuatanga pakitara pāmahana ≤625 ℃, teitei pāmahana pane me te mamaoa paipa taiepa pāmahana ≤600 ℃, me te kaha karihi exchanger wera me te oumu ngongo o te hinu kapiti wae.

    Taupānga

    Kei te whakamahia te nuinga ki te hanga paipa koranu maitai koranu teitei, paipa whakawhiti wera, paipa mamaoa pehanga teitei mo te hinu me te umanga matū
