He Tirohanga Whānui mō ngā Paipa Rino Ngāwari
Neke atu i te 70 tau te roa mai i te hanganga o te paipa rino ngāwari i ngā tau 1940. Nā tōna kaha nui, tōna roa, tōna ātete ki te waikura, tōna ātete ki te ru, tōna ngāwari ki te hanga me te maha atu o ngā āhuatanga pai, ko te paipa rino ngāwari te mea pai rawa atu i te ao o ēnei rā mō te kawe haumaru i te wai me te hau. Ko te rino ngāwari, e kiia ana ko te rino nodular, ko te rino graphite spheroidal rānei, e tohuhia ana e te noho o te graphite spheroidal i roto i ngā whakarewanga ka puta.
