Understanding the Difference Between SN4 and SN8 Double Wall Corrugated Pipes
In the world of construction and infrastructure, the choice of materials can significantly impact the longevity and efficiency of a project. Among the various options for piping, double wall corrugated (DWC) pipes stand out for their durability and versatility. However, choosing the right type of DWC pipe—specifically between SN4 and SN8 ratings—requires understanding their differences and applications.
What Are DWC Pipes?
Double wall corrugated pipes are designed with two layers: an inner smooth wall for optimal flow and an outer corrugated wall that adds strength and rigidity. These pipes are widely used for drainage and sewer systems, cable protection, and irrigation, owing to their lightweight nature and ease of installation compared to traditional materials.
SN4 vs. SN8: What’s the Difference?
The classification of SN4 and SN8 refers to the ring stiffness of the pipes, measured in kiloNewtons per square meter (kN/m²). This stiffness indicates the pipe’s ability to resist deformation and compression when subjected to external loads.
SN4 Pipes: These pipes have a ring stiffness of 4 kN/m², making them suitable for areas with low to moderate load. SN4 pipes are commonly used in residential and light commercial applications where the depth of bury or the live load on the surface is minimal.
SN8 Pipes: With a ring stiffness of 8 kN/m², SN8 pipes are designed to handle higher loads. They are ideal for deeper or more heavily trafficked installations such as public highways, large commercial projects, and deep burial applications. The enhanced stiffness ensures that the pipes can withstand higher external pressures without collapsing.
Choosing the Right Pipe
Selecting between SN4 and SN8 DWC pipes depends largely on the installation environment and the load conditions expected. For lighter, less demanding conditions, SN4 pipes offer a cost-effective yet robust solution. In contrast, for more challenging environments with higher load requirements, SN8 pipes provide the necessary durability and strength.
