I-AS 1074 (NZS 1074)iyipayipi lensimbi yase-Australia (yaseNew Zealand) kanye nezixhumi.
Isebenza kumapayipi ensimbi anentambo nokufakwa okucaciswe ku-AS 1722.1, namapayipi ensimbi aneziphetho eziyisicaba ukusuka ku-DN 8 kuya ku-DN 150.
Ugqinsi lwezindonga ezintathu zamapayipi ensimbi nawo acacisiwe, alula, aphakathi nendawo, futhi asindayo.
Amashubhu we-AS 1074 angenziwa yinoma yiliphiengenamthungonoma izinqubo ezishiselwe, nenqubo yokushisela ngokuvamile ibaERW.
Izinhlobo ezintathu zeziphetho zepayipi zifakiwe: ithafa, i-screwed, ne-socketed.

| I-AS 1074 (NZS 1074) | 0.045% ubuningi | 0.045% ubuningi | 0.4 ubuningi |
I-CE isifinyezo se-carbon equivalent, okudingeka itholwe ngokubala.
CE = C + Mn/6
Amandla amancane okukhiqiza: 195 MPa;
Amandla amancane okudonsa: 320 - 460 MPa;
Ubude: hhayi ngaphansi kuka-20%.
Ipayipi ngalinye lensimbi kufanele lihlolwe ngokukhetha enye yezindlela zokuhlola ukuqina kwepayipi lensimbi.
Ukuhlolwa kwe-Hydrostatic
Ipayipi lensimbi ligcina inani lokucindezela kwamanzi kwe-5 MPa isikhathi eside ngokwanele ngaphandle kokuvuza.
Ukuhlola Okungabhubhisi
Ukuhlolwa kwamanje kuka-Eddy kuhambisana ne-AS 1074 Appendix B.
Ukuhlolwa kwe-Ultrasonic ngokuhambisana ne-AS 1074 Appendix C.
Amabanga okuqina kodonga: alula, aphakathi nendawo, futhi asindayo.
Amabanga ogqinsi lwamapayipi ensimbi ayahluka kanjalo nokubekezelela kobubanzi obuhambisanayo bangaphandle.Ngezansi kunethebula lezisindo zalezi zigaba ezintathu zamapayipi ensimbi kanye nokubekezelelana kwe-OD okuhambisanayo.

Uma ipayipi lensimbi le-AS 1074 likhandisiwe, kufanele lihambisane ne-AS 1650.
Ubuso bepayipi likathayela kufanele buqhubeke, bushelelezi futhi busakazwe ngokulinganayo ngangokunokwenzeka, futhi bungabi namaphutha angaphazamisa ukusetshenziswa.
Amapayipi anemicu kufanele afakwe uthayela ngaphambi kokulutha.
Amashubhu azohlukaniswa ngombala ekugcineni ngendlela elandelayo:
| Ithubhu | Umbala |
| Ishubhu elikhanyayo | Brown |
| Ishubhu eliphakathi | Okuluhlaza okwesibhakabhaka |
| Ishubhu elisindayo | Okubomvu |
Singabakhiqizi nabahlinzeki bepayipi lensimbi yensimbi esezingeni eliphezulu abavela eChina, futhi siphinde sibe nesitoko sepayipi sensimbi esingenamthungo, sikunikeza izixazululo eziningi zamapayipi ensimbi!
