Chemical Requirement OF AS 1074 PIPES

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:

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.

Mechanical Requirement OF AS 1074 Carbon Steel Pipe

Our AS 1074 carbon steel pipes also meet all mechanical requirements. This includes tensile strength, yield strength, elongation, and hardness. These properties are crucial for the pipe’s ability to withstand pressure, resist deformation, and maintain its shape under stress. With UNIASEN, you’re getting a product that’s built to withstand the toughest conditions.

FAQs about AS 1074

what is as/nzs?

AS/NZS stands for Australian/New Zealand Standard. It is a set of technical specifications and guidelines developed by Standards Australia and Standards New Zealand, respectively.

These standards are used to ensure the quality, safety, and performance of products and services in both Australia and New Zealand.

In the context of steel pipes, AS/NZS standards may specify requirements for dimensions, materials, and performance characteristics. This ensures that the pipes meet the necessary standards for use in different applications.

UNIASEN also provides standards such as AS 1163. If you have more needs, please contact us.

What is AS 1074? What does it have to do with carbon steel pipes?

AS 1074 is a carbon steel pipe standard issued by Standards Australia. It stipulates various technical and performance requirements for carbon steel pipes to ensure their reliability and safety in different uses. We provide specific performance requirements and parameters.

What types of carbon steel pipes does AS 1074 apply to?

AS 1074 is suitable for a range of carbon steel pipes, including pipes used for water transmission, structural and mechanical applications. If you have other needs, contact us for a free quote.

What is the size range of AS 1074 standard pipe?

Our sizes cover DN 8 to DN 150 (nominal sizes).

How to ensure your carbon steel pipe products comply with AS 1074 standards?

We work with standards-compliant certification bodies to carry out the necessary testing and verification. Such as sealing test and bending test.

UNISEN’s tightness testing includes online non-destructive testing and hydrostatic testing.

Bend testing primarily determines a pipe’s ability to resist breaking or failing under pressure.

Through the above tests and inspections, we ensure that our products fully comply with AS 1074 standards.
