ASTM A519 Paipa maitai
Ka kapi tenei putorino mo te maha o nga karaehe o te waro me te koranu ngongo miihini, kua oti te wera, kua oti ranei te makariri.Ko te maitai e whakamahia ana i roto i te ngongo miihini ka taea te maka ki roto i te ingots, ka taea ranei te maka whenu.I te wa e werohia ana te rino o nga reanga rereke, ka hiahiatia te tautuhi i nga mea whakawhiti ka puta.Ko te ngongo tuitui he hua ngongo kaore he tui paiherea.I te nuinga o te wa ka hangaia e te rino mahi wera, me te mea e tika ana, ma te whakamatao i muri i te whakaoti i te hua ngongo wera-mahi hei whakaputa i te ahua e hiahiatia ana, te rahi me nga taonga.
Ko nga ngongo kia rite ki nga ahuatanga e whai ake nei: porowhita, tapawha, tapawha me nga waahanga motuhake.Me mahi te wetewete hei whakatau i nga paheketanga o nga huānga kua tohua.Mena ka whakamahia nga tikanga whakarewa tuarua, me whiwhi te tātari wera mai i tetahi ingot kua remeled, i te hua ranei o tetahi ingot kua remeled o ia whakarewa tuatahi.Me whakakikoruatia te ngongo ki te kiriata hinu i mua i te hanga hei aukati i te waikura ina tohua
