Me whakamatauria ia putorino maitai ma te kowhiri i tetahi o nga tikanga whakamatautau paipa paipa maitai.
Whakamātautau Hydrostatic
Ko te putorino maitai e pupuri ana i te uara pehanga wai o te 5 MPa mo te wa roa kaore e pakaru.
Whakamātautau kore-whakangaro
Ko te whakamatautau a Eddy o naianei e rite ana ki te AS 1074 Appendix B.
Te whakamātautau Ultrasonic i runga i te AS 1074 Appendix C.
Ko nga tohu matotoru o te pakitara: he maama, he reo, he taumaha.
He rereke nga tohu matotoru o te putorino rino me te rite ki nga waahanga o waho.Kei raro nei te tepu o nga taumahatanga o enei reanga e toru o te paipa maitai me nga whakaaheitanga OD.

Ko te mata o te putorino piauau kia noho tonu, kia maeneene, kia rite te tohatoha ka taea, me te kore he koha e raru ai te whakamahi.
Me piauau nga paipa me nga miro i mua i te miro.
Me wehewehe nga ngongo ma te tae o tetahi pito penei:
