He tirohanga whānui mō te paipa maitai koranu

Ka whakamahia te Paipa Rino Koranu i ngā mahi e hiahia ana ki ngā āhuatanga ātete waikura ngawari, he roa te mau, ā, he utu ōhanga hoki. Hei whakarāpopototanga, he pai ake ngā paipa koranu i ngā wāhi ka pakaru pea ngā paipa rino waro. E rua ngā momo maitai koranu - ko ngā maitai koranu teitei me ngā maitai koranu iti. Ko ngā paipa he maitai koranu iti he iti iho i te 5% te nui o te koranu. Engari ko te nui o te koranu o te maitai koranu teitei kei waenga i te 5% ki te 50%. Pērā i te nuinga o ngā koranu, ko te kaha pēhanga mahi o te Paipa Rino Kore Tuitui he 20% teitei ake i te paipa whakarewa. Nō reira, i ngā mahi he nui ake te pēhanga mahi hei whakaritenga, he tika te whakamahi i te paipa tuitui. Ahakoa he kaha ake i te paipa whakarewa, he nui ake te utu. Hei tāpiri, ko te mōrearea o te waikura intergranular i te rohe whakarewa e pāngia ana e te wera he nui ake i roto i te hua whakarewa. Ko te rerekētanga kitea i waenga i te Paipa Rino Koranu Whakarewa me te hua tuitui ko te hononga whānui i te roanga o te paipa. Heoi, i ēnei rā, nā te whanaketanga o te hangarau, ka taea te whakaiti i te hononga o te Paipa Rino Koranu ERW mā te maimoatanga mata, kia kore ai e kitea e te kanohi tangata.
