Engineering the Future of Stormwater Systems

In the realm of stormwater management, the choice of piping material is pivotal. Corrugated pipes, particularly those manufactured by Plasgain, are emerging as the superior alternative in Australia's infrastructure projects. Crafted in Victoria from recycled plastic, Plasgain’s plastic pipes mark a significant departure from traditional concrete options. This shift is not merely a matter of material preference but a testament to innovation, durability, and environmental stewardship. Concrete pipes, while long-standing staples in stormwater systems, often succumb to cracking and extensive maintenance over time. Plasgain's polypropylene (PP) pipes, however, offer a resilient, corrosion-resistant solution that stands the test of time and the elements. Beyond their robustness, these pipes are lighter, easier to install, and significantly more eco-friendly—attributes that underscore Plasgain's commitment to advancing sustainable engineering solutions.

Applications of Our Corrugated Pipes

Corrugated pipes, characterised by their distinctive design and superior material properties, are integral to a wide array of infrastructure projects. Their application is supported by technical specifications that underscore their adaptability and efficiency.

Corrugated pipes are the backbone of effective stormwater management systems, designed to ASTM F405 and AS/NZS 5065 standards for stormwater applications. Their dual-wall construction provides a smooth internal surface for optimal hydraulic performance (Manning’s n value of 0.009), facilitating rapid water conveyance and reducing the risk of blockages. Capable of handling flow rates exceeding 10 cubic metres per second, these pipes ensure efficient drainage even during intense rainfall events.

Large-Scale Infrastructure Projects

For highways, airports, and urban transit systems, Plasgain’s corrugated pipes offer unparalleled load-bearing capacity, compliant with AASHTO M294 and AS/NZS 2566.1 standards for live and dead loads. The unique corrugated design allows for deflection up to 7.5% without compromising structural integrity, making them suitable for installations under high-traffic areas where dynamic loads are a concern.

Environmental Management

In projects aimed at habitat restoration and flood control, these pipes play a crucial role in preserving natural water courses and managing excess water. The material's chemical inertness ensures that polypropylene pipes do not leach harmful substances into the environment, maintaining the ecological balance and supporting biodiversity.

Agricultural and Irrigation Systems

Agriculture benefits from the use of corrugated pipes in creating efficient irrigation and drainage systems. Their resistance to a wide range of pH levels (from highly acidic to basic environments) allows for deployment in varied agricultural settings without the risk of material degradation. Additionally, the pipes' flexibility accommodates ground movement and thermal expansion, reducing the likelihood of stress fractures and ensuring longevity in field installations.
