Whakaahuatanga Hua
Nga korero whanui
I roto i nga whenua maha, ko nga paipa e whiti ana, e rere whakarara ana ranei ki nga huarahi nui me nga reriwe e tiakina ana e te casing. Ka whakamahia nga Insulators Casing hei wehe i te pipeline kawe mai i te pipeline casing, he pai mo te paipa kawe wai me te hinu me te hau.
Ahuatanga Hua / Painga:
* He nui te uara whakamaarama hiko me te iti o te whakauru wai, na reira ka aukati i te rerenga me te pupuri i te wehenga hiko i waenga i te kaikawe me te pouaka.
* Ko te mata o roto he ripiripi hei aukati i nga pahekeheke me te tiaki i nga pakaru o te paninga.
* He kaha te kaha ki te tautoko i te taumaha paipa kawe.
* Te aukati i nga kino miihini i te wa e kumea ana ki roto i te pouaka.
* He ātete ki te wiri miihini me te waiariki me nga taumahatanga, ina koa ka puta i te wa o te whakaurunga me te whakaurunga.
