AS 1074 (NZS 1074)is an Australian (New Zealand) general-chinangwa simbi pombi uye fittings.
Inoshanda kumapombi esimbi ane shinda uye mafittings anotsanangurwa muAS 1722.1, uye mapaipi esimbi akadzikama kubva kuDN 8 kusvika kuDN 150.
Matatu emadziro makobvu epombi yesimbi anotsanangurwa zvakare, akareruka, epakati, uye anorema.
AS 1074 machubhu anogona kugadzirwa neimweisina musonokana welded process, ine welding process inowanzo kuveERW.
Mhando nhatu dzepombi dzinogumira dzinosanganisirwa: plain, screwed, uye socketed.

CE ipfupi yekabhoni yakaenzana, inoda kuwanikwa nekuverenga.
CE = C + Mn/6
Simba shoma regoho: 195 MPa;
Minimum tensile simba: 320 - 460 MPa;
Elongation: kwete pasi pe20%.
Imwe neimwe pombi yesimbi inofanirwa kuyedzwa nekusarudza imwe yesimbi pombi tightness test nzira.
Hydrostatic Test
Iyo pombi yesimbi inochengetedza kukosha kwemvura ye5 MPa kwenguva yakareba yakakwana pasina kubuda.
Muedzo Usingaparadzi
Muedzo wazvino waEddy unoenderana neAS 1074 Appendix B.
Ultrasonic kuyedza zvinoenderana neAS 1074 Appendix C.
Kukora kwemadziro mamakisi: akareruka, epakati, uye anorema.
Kukora kwemadziro mamakisi epombi yesimbi anosiyana uye ndozvinoita zvinoenderana nekunze kwedhayamita kushivirira.Pazasi pane tafura yezviyero zveaya magiredhi matatu esimbi pombi uye inoenderana OD kushivirira.
