AS 1074 (NZS 1074)yaiku pipa baja lan fitting umum Australia (Selandia Anyar).
Iki ditrapake kanggo pipa baja lan fitting sing ditemtokake ing AS 1722.1, lan pipa baja sing rata saka DN 8 nganti DN 150.
Telung tembok kekandelan pipa baja uga ditemtokake, entheng, medium, lan abot.
| Standar | P | S | CE |
| AS 1074 (NZS 1074) | 0,045% maks | 0,045% maks | 0,4 maks |
CE minangka singkatan kanggo setara karbon, sing kudu dipikolehi kanthi pitungan.
CE = C + Mn/6
Kekuwatan ngasilake minimal: 195 MPa;
Kekuwatan tarik minimal: 320 - 460 MPa;
Elongation: ora kurang saka 20%.
Saben pipa baja kudu diuji kanthi milih salah sawijining metode tes sesak pipa baja.
Tes Hidrostatik
Pipa baja njaga nilai tekanan banyu 5 MPa kanggo wektu sing cukup suwe tanpa bocor.
Tes Non-Ngrusak
Tes saiki Eddy cocog karo AS 1074 Lampiran B.
Pengujian ultrasonik miturut AS 1074 Lampiran C.
Tingkat kekandelan tembok: entheng, medium, lan abot.
Tingkat kekandelan tembok pipa baja beda-beda lan uga toleransi diameter njaba sing cocog.Ing ngisor iki tabel bobot saka telung gelar pipa baja lan toleransi OD sing cocog.

Yen pipa baja AS 1074 galvanis, mesthine selaras karo AS 1650.
Lumahing pipa galvanis kudu terus-terusan, lancar lan disebarake kanthi rata, lan bebas saka cacat sing bakal ngganggu panggunaan.
Pipa karo benang kudu galvanis sadurunge threading.
Tabung kudu dibedakake kanthi warna ing salah sawijining ujung kaya ing ngisor iki:
| tabung | warna |
| Tabung cahya | coklat |
| Tabung medium | Biru |
| Tabung abot | abang |
