AS 1074 (NZS 1074)he paipa rino me ngā taputapu whānui nō Ahitereiria (Aotearoa).
E pā ana tēnei ki ngā paipa rino miro me ngā hononga kua tohua i roto i te AS 1722.1, me ngā paipa rino pito papatahi mai i te DN 8 ki te DN 150.
E toru ngā matotoru o te pakitara o ngā paipa maitai kua tohua, arā, he māmā, he waenga, me te taumaha.
Ka taea te hanga i ngā ngongo AS 1074 e tētahi o ngākore honongangā tukanga whakarewa rānei, ko te tukanga whakarewa te tikanga whānuiERW.
E toru ngā momo pito paipa kei roto: he papatahi, he wiri, me he pūwero.

Ko te kupu CE he whakarāpopototanga mō te waro ōrite, me tātai tēnei mea.
CE = C + Mn/6
Te kaha whakaputa iti rawa: 195 MPa;
Te kaha kume iti rawa: 320 - 460 MPa;
Te roa: kaua e iti iho i te 20%.
Me whakamātautau ia paipa rino mā te whiriwhiri i tētahi o ngā tikanga whakamātautau piripono o te paipa rino.
Whakamātautau Waipūmau
Ka mau tonu te pēhanga wai o te paipa maitai i te 5 MPa mō te wā roa, me te kore e turuturu.
Whakamātautau Kore-Whakangaro
Ko te whakamātautau a Eddy o nāianei e hangai ana ki te AS 1074 Appendix B.
Whakamātautau ultrasonic i runga anō i te AS 1074 Appendix C.
Ngā mātotorutanga o te pakitara: māmā, waenga, me te taumaha.
Ka rerekē ngā matotoru o te pakitara o te paipa maitai, me ngā ātete diameter o waho. Kei raro nei he ripanga o ngā taumaha o ēnei momo paipa maitai e toru me ngā ātete OD e rite ana.

Mena he mea whakakikorua te paipa maitai AS 1074, me rite ki te AS 1650.
Me pūmau te mata o te paipa piauau, kia maeneene, kia taurite te tohatoha, ā, kia kore he hapa e whakararuraru i te whakamahinga.
Me whakakikorua ngā paipa miro i mua i te whakawirihia.
Me wehewehe ngā ngongo mā te tae i tētahi pito penei:
| Ngongo | Tae |
