1. Ko nga taputapu ka whakamahia anake mo te whakapiri i nga ngongo kua whakahiahia.Ko nga ngongo kua oti te hanga ma te whakamahi i enei taputapu he waahanga whakawhiti wera kaha.Kei te tohuhia e te kaha o te whakawhiti wera me te pehanga teitei, me te pai ki te urutau ki nga waahi teitei.Kei te whakamahia te nuinga i roto i te whakaora wera ururua, petrochemical, pūnaha whakawhiti wera o teihana hiko kōhua me ētahi atu ahumahi.
Ko te tono o nga ngongo i roto i te ruma whakawera oumu convection o te ahumahi petrochemical ka taea te whakanui ake i te paoa whakawhiti wera taha taha.E 2 ki te 3 te horahanga o nga ngongo kua whakahiatotia, he nui ake i to nga ngongo marama.I raro i te ahua o te hoahoa whaitake, ma te whakamahi i nga ngongo kua whakahiahia ka taea te whiwhi i te kaha o te wera rite te radiation.
2. Ko te ngongo kua whakahiato he waahanga whakawhiti wera whakakotahi i whakamahia ma te whakamahi i te kaha o te kaha o te kaha o te whakapiri momo whakaahuru me te whakapouri i te whakakotahitanga kaha.
3. Ko nga taputapu e mau ana i te rua-rama te whakarewa puku-kore fehokotaki'anga.Ka whakamahia te motuka hiko mo te wehenga o te upoko;me te aratohu raina e whakamahi ana i te kiriata upoko miihini.Ka whakatauhia te tika o te welding.
4. Ko te kaiao ngongo kua whakahiahia he miihini-hikohiko whakauru.Ko te waahanga mana hiko e tango ana i te mana o te kaupapa PLC me te tautuhinga tawhā atanga tangata-miihini, a he ngawari, he pono hoki te mahi.Ko nga tawhā fehokotaki'anga tango tautuhinga rorohiko papa kotahi.He u, he watea hoki tana mahi.
