AS 1074 (NZS 1074)yi Australian (New Zealand) umbhobho yentsimbi ngokubanzi-injongo kunye nokufakwa.
Isebenza kwimibhobho yentsimbi enemisonto kunye nezixhobo ezichazwe kwi-AS 1722.1, kunye nemibhobho yensimbi ene-flat-ephela ukusuka kwi-DN 8 ukuya kwi-DN 150.
Iindonga ezintathu zobunzima bombhobho wentsimbi nazo zicacisiwe, zilula, ziphakathi, kwaye zinzima.
Iityhubhu ze-AS 1074 zinokuveliswa yiyo nayiphi naengenamthungookanye iinkqubo ezidibeneyo, kunye nenkqubo ye-welding ngokubanziERW.
Iindidi ezintathu zokuphela kombhobho zibandakanyiwe: plain, screwed, and socketed.
| Umgangatho | P | S | CE |
| AS 1074 (NZS 1074) | 0.045% ubukhulu | 0.045% ubukhulu | 0.4 ubuninzi |
I-CE yi-shorthand ye-carbon equivalent, ekufuneka ifunyenwe ngokubala.
CE = C + Mn/6
Ubuncinci amandla okuvelisa: 195 MPa;
Ubuncinci bamandla obunzima: 320 - 460 MPa;
Elongation: hayi ngaphantsi kwe 20%.
Umbhobho ngamnye wentsimbi kufuneka uvavanywe ngokukhetha enye yeendlela zokuvavanya ukuqina kombhobho wentsimbi.
Uvavanyo lweHydrostatic
Umbhobho wensimbi ugcina ixabiso loxinzelelo lwamanzi lwe-MPa ye-5 ixesha elide ngokwaneleyo ngaphandle kokuvuza.
Uvavanyo olungangonakalisi
Uvavanyo lwangoku lukaEddy luhambelana ne-AS 1074 iSihlomelo B.
Uvavanyo lweUltrasonic ngokungqinelana ne-AS 1074 iSihlomelo C.
Amanqanaba obunzima bodonga: ukukhanya, okuphakathi, kunye nobunzima.
Amanqanaba obunzima bodonga lombhobho wentsimbi ayahluka kwaye ngokunjalo ukunyamezelwa kwedayamitha yangaphandle ehambelanayo.Ngezantsi itheyibhile yobunzima bala manqanaba amathathu ombhobho wensimbi kunye nokunyamezela kwe-OD okuhambelanayo.

Ukuba i-AS 1074 ipayipi yensimbi ifakwe i-galvanized, kufuneka ihambelane ne-AS 1650.
Umphezulu wombhobho we-galvanized uya kuqhubekeka, ngokugudileyo kwaye usasazwe ngokulinganayo, kwaye ukhululekile kwiziphene eziza kuphazamisa ukusetyenziswa.
Imibhobho enemisonto iyakugalelwa phambi kokuthunga.
Imibhobho iya kwahlulwa ngombala kwelinye icala ngolu hlobo lulandelayo:
| Umbhobho | Umbala |
| Umbhobho wokukhanya | Ntsundu |
| Umbhobho ophakathi | Luhlaza |
| Umbhobho onzima | Bomvu |
Singumvelisi wemibhobho yentsimbi yekhabhoni ekumgangatho ophezulu odityanisiweyo kunye nomthengisi ovela eChina, kunye nesitokhwe semibhobho yentsimbi engenamthungo, ekunika uluhlu olubanzi lwezisombululo zemibhobho yentsimbi!
