1. Whakaahuatanga ngawari:
1) Paerewa ASTM A387/A387M-11 Chromium-Molybdenum Alloy Steel Sheets for Pressure Vessels Chemical Composition
Pawera Pawera Tukunga Tikanga Whakaritea + Tempered/Annealed.
2) Kei ia reanga o waho atu nga Koeke 21L 22L me te 9 e waatea ana ki nga taumata o te kaha o te kaha o te kaha kua tohua i roto i nga ripanga Tiaki Tiaki.
E waatea ana nga karaehe 21L me te 22L na te mea ko te akomanga 1 te karaehe 91 e waatea ana hei karaehe 2. NOTE 1- Koeke 911, kua hipokina e tenei
whakapūtātanga, kua hipokina inaianei e te Whakatakotoranga A1017/A1017M.
3) Ka whakawhāitihia te mātotoru mōrahi o ngā pereti mā te kaha o te hanganga ki te whakatutuki i ngā whakaritenga rawa mihini kua tohua.
