AS 1074 (NZS 1074)ipombi yesimbi inoshandiswa zvakanyanya muAustralia (New Zealand).
Inoshanda kumapaipi esimbi ane shinda uye zvigadziko zvakataurwa muAS 1722.1, uye mapaipi esimbi ane magumo akatsetseka kubva kuDN 8 kusvika kuDN 150.
Mapaipi esimbi ane ukobvu hutatu hwemadziro, akareruka, ari pakati nepakati, uye anorema.

Simba shoma remukoho: 195 MPa;
Simba shoma rekudhonza: 320 - 460 MPa;
Kureba: kwete pasi pe20%.
Pombi yega yega yesimbi inofanira kuyedzwa nekusarudza imwe yenzira dzekuyedza kusimba kwepombi yesimbi.
Kuedzwa kweHydrostatic
Pombi yesimbi inochengetedza simba remvura re5 MPa kwenguva yakareba zvakakwana pasina kubuda kwemvura.
Muedzo Usingaparadzi
Bvunzo yaEddy iripo inoenderana neAS 1074 Appendix B.
Kuongororwa kweUltrasonic zvichienderana neAS 1074 Appendix C.
Magiredhi eukobvu hwemadziro: akareruka, ari pakati nepakati, uye anorema.
Magiredhi eukobvu hwemadziro emapaipi esimbi anosiyana uye ndizvo zvinoitawo maerekitironi ekunze anoenderana. Pazasi pane tafura yehuremu hwemagiredhi matatu aya emapaipi esimbi uye maerekitironi eOD anoenderana.

Kana pombi yesimbi yeAS 1074 yakagayiwa, inofanira kuenderana neAS 1650.
Pamusoro pepombi yakarukwa inofanira kuramba ichienderera mberi, yakatsetseka uye yakapararira zvakaenzana sezvinobvira, uye isina zvikanganiso zvingakanganisa kushandiswa.
Mapaipi ane shinda anofanira kugayiwa nemagetsi asati agadzirwa neshinda.
Machubhu anofanira kusiyaniswa neruvara kune rimwe divi seizvi:

| Chubhu inorema | Tsvuku |
Isu tiri vagadziri vemapaipi esimbi ecarbon emhando yepamusoro uye vatengesi vanobva kuChina, uye tiri vagadziri vemapaipi esimbi asina musono, tichikupai mhinduro dzakasiyana-siyana dzemapaipi esimbi!
