Whakaahuatanga Poto:

Ko te ngongo API 5CT OCTG te awa e whakamahia ana hei kawe i te hinu maru, i te hau maori ranei mai i nga hangahanga hanga ki nga waahi o te papa whenua mo te tukatuka i muri i te otinga o te keri.I te wa o te tangohanga, me mau tonu te ngongo OCTG ki te pehanga, me tino kaha ki te aukati i nga kawenga me nga huringa e pa ana ki te hanga me nga mahi mahi.I tua atu, ko te rahi o nga ngongo kia rite ki nga reiti e tumanakohia ana mo te whakaputa hinu me te hau.Na te mea mena he nui rawa te ngongo, ka whai paanga ohaoha taatau ki tua atu i te utu mo te ngongo hinu me te hau ano, heoi, mena he iti rawa te ngongo API, ka aukati te hanga hinu, hau ranei, a mena ka penei tonu nga ahuatanga. ka pa ki nga mahi ohaoha o muri mai o te puna.Ko te tikanga, he rite tonu te hanga o nga ngongo ki te pouaka, engari he tikanga taapiri e kiia nei ko te "whakapouri" ka whakamahia hei whakapakeke i nga paipa.
