AS 1074 (NZS 1074)iyipayipi lensimbi elisetshenziswa kabanzi lase-Australia (eNew Zealand) kanye nezinto zokufakelwa.
Isebenza kumapayipi ensimbi anezintambo kanye nokufakwa okuchazwe ku-AS 1722.1, kanye namapayipi ensimbi aneziphetho eziyisicaba kusukela ku-DN 8 kuya ku-DN 150.
Kucaciswe nobukhulu bodonga obuthathu bepayipi lensimbi, obulula, obuphakathi, nobunzima.
Amashubhu e-AS 1074 angakhiqizwa yinoma yimuphingaphandle komthungonoma izinqubo ezihlanganisiwe, inqubo yokunamathisela ngokuvamile isetshenziswaI-ERW.
Kunezinhlobo ezintathu zeziphetho zamapayipi: ezingenalutho, ezifakwe ngezikulufo, nezifakwe ngesokhethi.
| Okujwayelekile | P | S | CE |
| AS 1074 (NZS 1074) | Ubuningi obungu-0.045% | Ubuningi obungu-0.045% | Ubuningi obungu-0.4 |
I-CE ifushaniswa ne-carbon equivalent, okudingeka itholakale ngokubalwa.
CE = C + Mn/6
Amandla okukhiqiza amancane: 195 MPa;
Amandla amancane okudonsa: 320 - 460 MPa;
Ukwandiswa: okungenani u-20%.
Ipayipi ngalinye lensimbi kufanele lihlolwe ngokukhetha enye yezindlela zokuhlola ukuqina kwepayipi lensimbi.
Ukuhlolwa Kwamanzi
Ipayipi lensimbi ligcina inani lokucindezela kwamanzi elingu-5 MPa isikhathi eside ngokwanele ngaphandle kokuvuza.
Ukuhlolwa Okungabhubhisi
Ukuhlolwa kuka-Eddy kwamanje kuhambisana ne-AS 1074 Appendix B.
Ukuhlolwa kwe-Ultrasonic ngokuhambisana ne-AS 1074 Appendix C.
Amazinga okujiya kodonga: alula, aphakathi nendawo, futhi anzima.
Amazinga okujiya kodonga lwepayipi lensimbi ayahlukahluka futhi kanjalo nokubekezelelana kobubanzi bangaphandle okuhambisanayo. Ngezansi kunethebula lesisindo salezi zigaba ezintathu zepayipi lensimbi kanye nokubekezelelana kwe-OD okuhambisanayo.

Uma ipayipi lensimbi le-AS 1074 ligayiwe, kufanele lihambisane ne-AS 1650.
Ubuso bepayipi elihlanganisiwe kufanele buqhubeke, bube bushelelezi futhi busabalaliswe ngokulinganayo ngangokunokwenzeka, futhi bungabi namaphutha angaphazamisa ukusetshenziswa.
Amapayipi anezintambo kufanele aqiniswe nge-galvanized ngaphambi kokufakwa kwezintambo.
Amapayipi kufanele ahlukaniswe ngombala ngakolunye uhlangothi kanje:
| Ipayipi | Umbala |
| Ipayipi elikhanyayo | Insundu |
| Ipayipi eliphakathi | Okuluhlaza okwesibhakabhaka |
| Ipayipi elisindayo | Okubomvu |
Singumkhiqizi kanye nomhlinzeki wamapayipi ensimbi yekhabhoni ashiselwe ngekhwalithi ephezulu avela eShayina, futhi siphinde sibe ngumthengisi wamapayipi ensimbi angenamthungo, sikunikeza izixazululo eziningi zamapayipi ensimbi!
