AS/NZS 1074

AS 1074 (AS/NZS 1074) is a common standard in Australia and New Zealand, the full title of which is AS/NZS 1074: Steel tubes and tubulars for ordinary service. This standard specifies the dimensions, properties, fabrication and testing requirements for use with steel tubes.AS 1074 is primarily used in non-load bearing structures such as those conveying liquids, gases, powders or granular materials.

Chemical Requirements of AS/NZS 1074

Our AS 1074 Steel Pipes meet the stringent chemical requirements set by the standard. The composition of the steel is carefully controlled to ensure optimal performance and durability. This includes the right balance of carbon, manganese, phosphorus, sulfur, and silicon. The chemical composition plays a crucial role in determining the pipe’s mechanical properties, corrosion resistance, and weldability.

2.1 PROCESS OF MANUFACTURE. Tubes may be either welded or seamless .

2.2 MATERIAL. Tubes shall be manufactured from steel which shows, not more than 0.045 percent of sulfur and not more than 0.045 percent of phosphorus. Carbon equivalent as calculated from the following equation shall not exceed 0.4:

carbon equivalent equation

Mechanical Requirements of AS/NZS 1074

The mechanical requirements of our AS/NZS 1074 Steel Pipes are strictly adhered to, ensuring high strength, toughness, and ductility. These properties are essential for the pipe’s ability to withstand pressure, temperature changes, and mechanical stress. The mechanical properties are determined by factors such as the steel’s chemical composition and the manufacturing process.


Lengths or strips cut from selected tubes and tested in accordance with AS 1391 shall show–
(a) minimum yield strength of 195 MPa;
(b) a tensile strength of between 320 MPa and 460 MPa; and
(c) an elongation of not less than 20 percent on a gauge length of 5.65√So where So is the original cross-sectional area of the test piece.
NOTE:Where other gauge lengths are used,the corresponding elongation on 5.65√So can be obtained from BS 3894:Part 1.

AS/NZS 1074 Production Tolerance

Production Tolerance

PERMISSIBLE VARIATION IN THICKNESS,DIAMETER. AND MASS
The following manufacturing tolerances shall be permitted on the tubes:
(a) Thickness:
Light welded tubes + unlimited, – 8 percent.
Medium and heavy tubes –
Welded…….+ unlimited, – 10 percent.
Seamless….. + unlimited, – 12.5 percent.
(b)Ouside diameler:
Light tubes……as given in Table 2.1
Medium tubes……as given in Table 2.2.
Heavy tubes……as given in Table 2.3.
(c)Mass.
The mean consignment mass for quantities of 150 m and over of one size shall not deviate from the standard mass by more than ±4 percent.No single tube shall deviate from the standard mass by more than + 10, – 8 percent.

AS/NZS 1074 Test Project

Flattening test (90°): During the welding test, we compress the outer diameter of the original pipe to the level of 75% to ensure that the weld does not crack. During the material testing process, we further flattened the pipe to 60% of the original outer diameter, and carefully observed that except for the weld part, the rest of the metal parts did not crack.

Tightness test: Carry out online non-destructive testing (eddy current) or hydraulic test according to the pressure standard shown in the above table, and ensure that the test duration does not exceed 5 seconds.

Flaring test: test the plastic deformation ability and processing performance of the steel pipe.

Non-destructive testing: Use a variety of methods such as ultrasonic testing, X-ray testing or magnetic particle testing to find any potential defects or cracks that may exist inside the steel pipe.

Metallographic inspection: Through the observation and analysis of the metallographic structure of the steel pipe, to understand its internal structure and organization status, and to evaluate its performance and quality.

Note:
1. AS 1074 is for threaded pipe and all threads should conform to the requirements. For a given size, the base length of the effective thread should be reduced to 80% of the sum of the fitting allowance plus the specified length.
2. The length of each pipe should be within 8 mm of the specified length.
3. Each pipe needs to be tested for tightness and needs to be hydrostatically tested at a pressure of 5 MPa and maintained for a long enough period of time to ensure that the pipe does not leak.
4. The bending test should not show any fracture. Welded pipe should be bent until the weld is 90 degrees from the curved surface
5. Galvanized pipe fittings should receive 90° cold rolling without cracking. and have a continuous, smooth surface.
6. Unless specified, pipes should have parallel pipe threads.
7. The tensile strength of the pipe material should not be less than 300 MPa.
