AS/NZS 1074

AS/NZS 1074

AS/NZS 1074 is the standard for steel tubes and tubulars for ordinary service. In accordance with AS1722.1, AS/NZS 1074 specifies requirements for threaded steel tubes and tubulars, as well as plain-end steel tubes, suitable for screwing, with nominal sizes ranging from DN 8 to DN 150 inclusive (nominal size) and wall thicknesses designated as Light (lightest), Medium (medium), and Heavy (heaviest).

Test and Inspections of AS/NZS 1074

- Leak Tightness Test

Online NDT
Hydro-test

- Flattening Test (90°)

Flatten the tube up to 75% of its original outside diameter (OD) for weld testing purposes. It should not have any cracks in it.
Flatten the tube up to 60% of its original outside diameter (OD). There are no flaws in the metal other than those in the welds themselves.
