Ngā Tohu Hua

1. Tirohanga Whānui – He aha i whakamahia ai te paipa whakakikoruatia X65+316L

Mō ngā paipa e kawe ana i te hau māori kei roto te hauhā waro (CO₂) engari he iti noa te hauwai whanariki (H₂S) me te iti o te pūhaumāota, ka tere te waikura o te maitai waro totoka, ko te maitai kore waikura totoka 316L ia he nui rawa te whakaritenga me te utu nui.

Paipa whakakikoruatia ki te whakarewa X65+316Le tuku ana i te ara waenga tino pai:

Paparanga X65 o wahohe kaha teitei (te iti rawa o te hua 450 MPa), he pakari pakaru, he pupuri pēhanga – koinei tonu te mea e mōhiotia ana te paipa raina API 5L X65.

Whakatakotoranga o roto 316Lka pā tika ki te wai, ka ātete ki te waikura CO₂, te waikura whānui, me ngā āhuatanga waikawa ngawari.

Ka honoa pūmau ngā paparanga e rua e te hononga whakarewa (te hononga rōra wera + te hanganga JCOE). Kāore he mōrearea o te hinga o te arai, te miro, te wehe rānei – he rerekē ki te paipa kua whakarārangihia ā-mīhini.

He whānuitia te whakamahinga o tēnei ranunga i roto ingā pūnaha kohikohi hau māori reka,Ngā paipa whakaora hinu whakarei ake o te CO₂ (EOR),ngā raina werohanga wai, mengā raina rere hinu me te hau iti-hauora.
