CT80 API 5ST ngongo Mirohia Te Kaha Teitei
Ko te ngongo whiri (CT), e mohiotia ana ano he ngongo ngongo, he kaha teitei, he pai te ngongo, he paipa paipa paipa paipa ki te waikura.He mano mita te roa o te reel.Inaianei, me te whakawhanaketanga o nga miihini ngongo me nga taputapu e pa ana, kua whakamahia te hangarau whakahaere ngongo ki te keri, te mahi, te whakamatautau pai, te hanga hinu, te whakaongaonga, te whakaoti me etahi atu mara.
To tatou ihirangi iti o te parathion rauemi ngongo porowhita tikanga, hanganga rite, āhuatanga mīhini e tika ana, piko pōkai he iti iho i te 0.80, te rerekētanga i roto i ngā āhuatanga kaha i roto i ngā wāhanga rerekē iti 50MPa ranei.Ko nga taonga miihini katoa e hono ana ki te tohu API Spec 5ST, a he tino pai te aukati ngenge.
Ka taea e te kaiwhakamahi te kowhiri i nga mea e hiahiatia ana me te maitai kia rite ki nga tikanga.Ka taea te whakarite i te rahi kia rite ki te API Spec 5ST me nga whakaritenga a te kaiwhakamahi.
