AS 1074 (NZS 1074)yog ib lub yeeb nkab hlau thiab cov khoom siv dav dav hauv tebchaws Australia (New Zealand).
Nws siv rau cov kav hlau threaded thiab cov fittings teev nyob rau hauv AS 1722.1, thiab cov kav hlau tiaj tiaj los ntawm DN 8 txog DN 150.
Peb qhov tuab ntawm cov yeeb nkab hlau kuj tau teev tseg, sib, nruab nrab, thiab hnyav.
AS 1074 cov raj tuaj yeem tsim los ntawm ib qho twgtsis muaj qhov tsis sib xwslos yog cov txheej txheem welded, nrog rau cov txheej txheem welding feem ntau yogERW.
Muaj peb hom yeeb nkab kawg: tiaj tus, ntsia hlau, thiab qhov (socketed).

| AS 1074 (NZS 1074) | 0.045% siab tshaj | 0.045% siab tshaj | 0.4 siab tshaj |
CE yog luv rau carbon sib npaug, uas yuav tsum tau txais los ntawm kev xam.
CE = C + Mn/6
Lub zog tsawg kawg nkaus: 195 MPa;
Lub zog tensile tsawg kawg nkaus: 320 - 460 MPa;
Kev nthuav dav: tsis pub tsawg dua 20%.
Txhua lub yeeb nkab hlau yuav tsum tau kuaj los ntawm kev xaiv ib qho ntawm cov txheej txheem kuaj xyuas qhov nruj ntawm cov yeeb nkab hlau.
Kev Ntsuas Hydrostatic
Cov yeeb nkab hlau tswj tau qhov dej siab ntawm 5 MPa rau lub sijhawm ntev txaus yam tsis muaj qhov xau.
Kev Ntsuas Tsis Ua Rau Puas Tsuaj
Eddy qhov kev xeem tam sim no yog raws li AS 1074 Appendix B.
Kev kuaj ultrasonic raws li AS 1074 Appendix C.
Cov qib tuab ntawm phab ntsa: lub teeb, nruab nrab, thiab hnyav.
Cov qib tuab ntawm phab ntsa ntawm cov yeeb nkab hlau sib txawv thiab qhov kev kam rau sab nraud kuj sib xws. Hauv qab no yog daim ntawv teev qhov hnyav ntawm peb qib ntawm cov yeeb nkab hlau no thiab qhov kev kam rau OD sib xws.

Yog tias AS 1074 cov yeeb nkab hlau yog galvanized, nws yuav tsum ua raws li AS 1650.
Qhov saum npoo ntawm cov yeeb nkab galvanized yuav tsum txuas ntxiv mus, du thiab faib sib npaug li sai tau, thiab tsis muaj qhov tsis zoo uas yuav cuam tshuam rau kev siv.
Cov kav dej nrog cov xov yuav tsum tau galvanized ua ntej threading.
Cov raj yuav tsum tau sib txawv los ntawm xim ntawm ib kawg raws li nram no:
| Lub raj | Xim |
| Lub teeb raj | Xim av |
| Lub raj nruab nrab | Xiav |
