AS 1074 (NZS 1074)yaiku pipa lan perlengkapan baja tujuan umum Australia (Selandia Baru).
Iki ditrapake kanggo pipa lan sambungan baja berulir sing ditemtokake ing AS 1722.1, lan pipa baja ujung rata saka DN 8 nganti DN 150.
Telung kekandelan tembok pipa baja uga ditemtokake, entheng, sedheng, lan abot.
| Standar | P | S | CE |
| AS 1074 (NZS 1074) | maksimal 0,045% | maksimal 0,045% | 0.4 maksimal |
CE iku cekakan saka padanan karbon, sing kudu dipikolehi kanthi itungan.
CE = C + Mn/6
Kekuatan luluh minimal: 195 MPa;
Kekuwatan tarik minimal: 320 - 460 MPa;
Elongasi: ora kurang saka 20%.
Saben pipa baja kudu diuji kanthi milih salah siji metode uji kekencengan pipa baja.
Tes Hidrostatik
Pipa baja njaga tekanan banyu 5 MPa sajrone wektu sing cukup suwe tanpa bocor.
Tes Non-Destruktif
Tes Eddy saiki miturut AS 1074 Lampiran B.
Pengujian ultrasonik miturut AS 1074 Lampiran C.
Tingkat kekandelan tembok: entheng, sedheng, lan abot.
Tingkat kekandelan tembok pipa baja beda-beda lan uga toleransi diameter njaba sing cocog. Ing ngisor iki tabel bobot telung tingkat pipa baja iki lan toleransi OD sing cocog.

Yen pipa baja AS 1074 digalvanis, kudune miturut AS 1650.
Permukaan pipa galvanis kudu kontinu, alus lan rata sabisa-bisane, lan bebas saka cacat sing bakal ngganggu panggunaan.
Pipa nganggo ulir kudu digalvanis sadurunge dipasang ulir.
Tabung kudu dibedakake miturut warna ing salah sawijining pucuk kaya ing ngisor iki:
| Tabung | Werna |
| Tabung cahya | Coklat |
| Tabung medium | Biru |
| Tabung abot | Abang |
