Ko ngā painga o ngā paipa maitai koranu kore-whakairoiro e whai ake nei i ngā paipa maitai noa:

Te kaha me te ātete ki te waikura: Kei roto i ngā paipa maitai koranu ngā huānga pēnei i te chromium, te molybdenum, te titanium, me te nickel, e whakapai ake ana i te kaha, te pakeke, me te ātete ki te waikura o ngā paipa maitai, ā, he tino pai mō te whakamahi i roto i ngā taiao pāmahana teitei, pēhanga teitei, waikura rānei.

He ātete tino pai ki te pāmahana teitei: Ka taea e ngā paipa maitai koranu te pupuri i te kaha pumau me te ātete ki te waikura i roto i ngā taiao pāmahana teitei. He mea whakamahi ēnei hei hanga taputapu e mahi ana i ngā pāmahana teitei, pērā i ngā kohua, ngā whakawhiti wera, me ētahi atu.

He pai te ngāwari me te kirihou: Nā te mea he maha ngā huānga koranu, he pai ake ngā paipa maitai koranu tuimotu i ngā paipa maitai noa i roto i te ngāwari me te kirihou, kāore hoki e ngāwari ki te whati, ā, he pai hoki mō ngā taiao e hiahia ana kia nui ake te pēhanga me te ahotea.

Ātete kakahu: He tino ātete kakahu ngā paipa maitai koranu, ā, he pai mō te whakamahi i roto i ngā taiao ahumahi he nui ake te kakahu.

Ngā ahumahi tono matua o ngā paipa maitai koranu tui
E whakamahia whānuitia ana ngā paipa maitai koranu tui kore i roto i ngā mara ahumahi maha, tae atu ki:

Te umanga hinu me te hau māori: I roto i te tango me te kawe hinu me te hau, he whānuitia te whakamahinga o ngā paipa maitai koranu nā te mea e hiahiatia ana he paipa pēhanga teitei me te ātete ki te waikura.

Ahumahi hiko: He maha ngā wā ka whakamahia ngā paipa maitai koranu kore-whakauru ki ngā taputapu pēnei i ngā kohua, ngā whakawhiti wera, me ngā paipa pēhanga teitei nā te mea ka taea e rātou te tu atu i ngā pāmahana teitei me ngā pēhanga teitei.

Ngā umanga matū me te hinu-matū: Ka whakamahia ngā paipa maitai koranu hei kawe i ngā wai matū me ngā hau i te wā o te tukanga whakaputa, ā, ka taea te ātete ki te waikura me te pāmahana tiketike.

Ahumahi mana karihi: Me whai rauemi kaha, pāmahana teitei, ātete ki te irahiko ngā pūnaha tauhohenga karihi, ā, ka tutuki i ngā paipa maitai koranu ēnei whakaritenga.

Ko ngā paipa rino tui matua o Sanonpipe ko ngā paipa kōhua, ngā paipa tongi, ngā paipa hinu, me ngā paipa hanganga.
