Kei te teihana ngā ipu rokiroki hauwai pēhanga teitei (pēhanga mahi 87.5MPa) me ngā mana pupuri hinengaro motuhake, me ngā pūwero hauwai e peia ana e te wai 90MPa me ngā waeine whakamatao-mua. Ka taea e te pūnaha te whakaoti i te tukanga whakakī hinu pēhanga teitei 70MPa katoa mō ngā waka pāhihi i roto i te 3-5 meneti. Ka whakauruhia e ngā kaitātari he pūnaha whakapūmau maha-wāhanga me ngā rauropi whakahaere pēhanga tika, me te pihi whakakī hinu e piri pono ana ki te kawa o te ao SAE J2601-2 (70MPa), e whakarite ana i te whakakī hinu haumaru, whai hua me te kore e whakararu i te pūnaha pūtau wahie.

I hangaia mō te taiao mahi teitei, paripari o te tonga-mā-uru o Haina, kei roto i te pūnaha ngā arotautanga motuhake:

• Kua arotauhia te whakamatao i waenga i ngā wāhanga mō ngā pūwhakapūngao kia mau tonu ai te pai o te tohatoha wera i raro i te mātotorutanga o te hau.
• Te utu hihiri i roto i ngā rauropi whakakī hinu, te whakarerekē i ngā tawhā whakahaere pēhanga-pāmahana i runga i te pāmahana taiao me te teitei.
• He parenga whakarei ake mō ngā taputapu nui, me ngā pūnaha hiko kua hangaia hei ātete ki te makuku me te aukati i te haukū, e urutau ana ki ngā āhuarangi rerekē.

Kua whakatūria he arai haumaru e whā ngā taumata o te "rauemi-hanganga-whakahaere-āwhati":

• Ngā Rauemi me te Hanganga: Ko ngā paipa me ngā takirere pēhanga teitei he mea whakamahi i te kowiri tira 316L, ā, kua whakamatautauria 100% kore-whakangaro.
• Haumaru Hanganga: Kei te wāhi rokiroki ngā pakitara pahūtanga me ngā taputapu whakawātea pēhanga; kei te wāhi whakakī hinu ngā tohu tawhiti haumaru me ngā whakaurunga ārai-tukituki.
• Aroturuki Maamaa: Mā te pūnaha kite turuturu moroiti e hangai ana ki te taiaho mō te hauwai pēhanga teitei ka taea te aroturuki i te wā-tūturu me te taunga turuturu.
• Urupare Āwhata: Ka taea e te pūnaha Whakaweto Āwhata (ESD) takirua-porowhita te whakatutuki i te wehenga hauwai katoa o te teihana i roto i te 300 ms.

Mā te Pūhara Whakahaere Kapua Hauwai Teihana ka taea te whai i ngā raraunga katoa o te tukanga whakakī hinu, te matapae i te hauora o ngā taputapu, me te tātari whānui i te whakapaunga pūngao. Ka tautoko te pūhara i te hononga ki ngā pūnaha raraunga motuka, ka whakarato i ngā taunakitanga rautaki whakakī hinu whaiaro mō ngā waka pūtau wahie, ā, ka tuku i ngā āheinga tātaritanga hapa mamao me te whakahou pūnaha.
