Tirohanga
Kei te whakahīhī mātou i te whakatutukitanga o te kiritaki teitei me te whakaae whanui na te whai tonu i te kounga teitei e rua mo te hua me te ratonga mo a maatau paipa raina maamaa, Ka noho pono matou ki te whakarongo mai i a koe. Tukuna mai he waahi ki a matou ki te whakaatu ki a koe i to maatau ngaiotanga me to matou hikaka. Kei te mihi maioha ki nga hoa pai mai i nga porowhita maha i nga kaainga me tawahi kei te mahi tahi! Na te mea ko nga otinga tino nui o to maatau wheketere, kua whakamatauria a maatau raupapa otinga ka riro i a maatau nga tiwhikete mana mohio. Mo nga tawhā taapiri me nga korero mo te raarangi taonga, paatohia te paatene kia whiwhi korero taapiri.
Taupānga
Ka whakamahia te pipeline ki te kawe i te hinu, te mamaoa me te wai i toia mai i te whenua ki nga umanga umanga hinu me te hau ma te paipa.

Whakaritenga Whakamatau
Te whakamatautau hydrostatic
Ko te paipa kia mau ki te whakamatautau hydrostatic me te kore e pakaru mai i te tui whiri, i te tinana paipa ranei. Kaore e tika kia whakamatauria nga hononga ki te hydrostatic mena kua pai te whakamatau i nga waahanga paipa i whakamahia.
Whakamatautau piko
Karekau he kapiti ki roto i tetahi waahanga o te waahanga whakamatautau, kaore hoki e puta te whakatuwheratanga o te paihere.
Whakamātautau papatahi
Ko nga paearu whakaae mo te whakamatautau papatahi ko:
- Paipa EW D<12.750 in:
- X60 me T 500in. Karekau he tuwhera o te weld i mua i te iti iho o te tawhiti i waenga i nga papa i te 66% o te diameter o waho. Mo nga reanga me nga pakitara katoa, 50%.
- Mo te paipa me te D/t> 10, kaua e whakatuwherahia te weld i mua i te iti iho o te tawhiti i waenga i nga papa i te 30% o te diameter o waho.
- Mo etahi atu rahi tirohia te katoa o nga korero API 5L.
Te whakamatautau a te CVN mo te PSL2
He maha nga rahi paipa PSL2 me nga tohu e hiahia ana kia CVN. Ko te paipa tuitui ka whakamatauria ki te tinana. Ko te paipa paihere me whakamatauria i roto i te tinana, te paipa paipa me te rohe e pa ana ki te wera. Tirohia te katoa o nga korero API 5L mo te tūtohi o nga rahi me nga tohu me nga uara hiko whakauru.
