Australian Steel Flanges Standards

Australian pipe flange standards ensure the reliable design, material specifications, and dimensional accuracy of flanges used in industrial applications, ensuring safety and performance in piping systems. The primary standard governing flanges in Australia is AS 4087, which defines the requirements for flanges used in pressure piping systems and other critical infrastructure.

AS 4087 - Metallic Flanges for Waterworks
This standard defines the design, materials, dimensions, and testing for flanges used in water distribution systems, ensuring compatibility with pressure and temperature requirements.
AS 2129 - Flanges for Pipes
Outlines specifications for flanges in industries like oil, gas, and petrochemical, including various types (slip-on, weld neck, blind, threaded) and pressure ratings (150, 300, 600, 900, 1500, and 2500).
AS 2862 - Flanges for Petroleum and Chemical Industries
Tailored for high-temperature and high-pressure systems in the petroleum and chemical industries, with flanges made from corrosion-resistant materials.
AS 4331 - Flanges for Cast Iron Piping Systems
Specifies flanges for water and sewage systems made from cast iron, designed for lower pressures and offering durability and cost-effectiveness.
ASME B16.5 - Pipe Flanges and Flanged Fittings
An international standard commonly used in Australia, specifying design, materials, and dimensions for high-pressure flanges made from carbon steel, stainless steel, and alloy steels.

What types of flanges are covered under AS/NZS 4331.1?

AS/NZS 4331.1 covers several types of flanges including slip-on flanges, weld neck flanges, and blind flanges, all designed for use in cast iron piping systems. These flanges are typically used in low to medium-pressure systems such as water and wastewater pipelines.

How does AS/NZS 4331.1 differ from other flange standards?

AS/NZS 4331.1 focuses specifically on flanges made from cast iron, offering specifications suited for waterworks and similar applications. It differs from other flange standards, such as ASME or ANSI, which are often used for steel flanges in high-pressure and heavy-duty industrial applications.

Are AS/NZS 4331.1 flanges compatible with other standards?

While AS/NZS 4331.1 is tailored to Australian and New Zealand markets, flanges manufactured to this standard can often be compatible with other international flange standards, such as ASME or ISO, depending on the application requirements and specific dimensions.
