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 katoaAPI 5Lwhakaritenga.
Ko 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 katoaAPI 5Lwhakapūmautanga mō te tūtohi o ngā rahi me ngā kōeke me ngā uara pūngao kua mimiti.
