Its popularity stems from its flexibility, strength, and resistance to chemicals, making it a preferred choice for water supply, irrigation, and other fluid transportation needs.
In this article, we will explore the different poly pipe sizes available in Australia and how they can be used in different projects.
One of the key advantages of poly pipe is its wide range of sizes, which allows for flexibility in design and installation.
Poly pipe sizes in Australia typically range from 16mm to 1200mm in diameter, catering to a variety of applications from small residential projects to large-scale commercial and agricultural installations.

For smaller residential projects such as backyard irrigation systems or garden watering, smaller poly pipe sizes like 16mm to 25mm are commonly used.
These sizes are lightweight and easy to handle, making them ideal for DIY enthusiasts or homeowners looking to set up their irrigation systems.
Moving up in size, poly pipe sizes in the range of 32mm to 50mm are often used for larger residential properties or small commercial applications.
These sizes are suitable for higher flow rates and can accommodate multiple outlets, making them a popular choice for irrigation systems in parks, schools, or small farms.

When it comes to larger projects such as agricultural irrigation, industrial applications, or municipal water supply, poly pipe sizes ranging from 63mm to 1200mm are commonly used.
These larger sizes are designed to handle high flow rates and pressure requirements, making them suitable for conveying large volumes of water over long distances.
The versatility of poly pipe sizes in Australia also extends to the type of material used.
Poly pipe is available in different grades of polyethylene, including low-density polyethylene (LDPE), medium-density polyethylene (MDPE), and high-density polyethylene (HDPE).
Each grade offers specific properties and benefits, allowing users to choose the right material for their specific application.
poly pipe sizes australia uses
For example, LDPE poly pipe is commonly used for low-pressure applications such as drip irrigation or landscaping, thanks to its flexibility and ease of installation.
On the other hand, MDPE poly pipe is often chosen for medium-pressure applications like residential water supply or gas distribution, offering a good balance of flexibility and strength.
When it comes to high-pressure applications or where durability is a priority, HDPE poly pipe is the preferred choice.
HDPE pipes are known for their high strength, corrosion resistance, and long-term reliability, making them suitable for demanding applications such as agricultural irrigation, mining, or industrial fluid transport.
In addition to the range of sizes and materials available, poly pipe in Australia is also offered in different pressure ratings to suit various requirements.
SDR, or Standard Dimension Ratio, is a common way to classify poly pipe based on its pressure rating and wall thickness.
The higher the SDR value, the thinner the wall thickness and the higher the pressure rating.
For instance, SDR 11 poly pipe is rated for higher pressure applications up to 160 psi, making it suitable for pressurized water supply or industrial fluid transport.
On the other hand, SDR 17 poly pipe is designed for lower pressure applications up to 100 psi, such as gravity-fed irrigation systems or underground drainage.
In conclusion, poly pipe sizes in Australia offer a wide range of options to meet the diverse needs of different projects and applications.
From small residential irrigation systems to large-scale agricultural projects, poly pipe provides a durable, cost-effective, and flexible solution for fluid transportation.
By choosing the right poly pipe size, material, and pressure rating, users can ensure a reliable and efficient piping system that meets their specific requirements.
