Types of 8 Inch PVC Pipes
Schedule 40 PVC Pipe
Schedule 40 PVC pipe is one of the most commonly used types for plumbing and drainage. It has a wall thickness that can handle moderate pressure, making it suitable for a variety of applications including irrigation, drainage, and even some potable water systems. You can find this type of pipe at retailers like Lowe’s and Ferguson.
Schedule 80 PVC Pipe
Schedule 80 pipes have thicker walls compared to Schedule 40, allowing them to withstand higher pressures. They are typically used in industrial applications or where increased durability is required. The cost for Schedule 80 is generally higher, reflecting its enhanced capabilities.
SDR-21 (CL 200) PVC Pipe
SDR-21 pipes are designed for potable water applications and are often used in municipal water distribution systems. They are compliant with various standards, including AWWA C900, ensuring their suitability for drinking water. Retailers like Kuhlman Corp offer a range of these products.
DWV PVC Pipe
DWV pipes are specifically designed for drainage, waste, and vent applications. They are thinner than pressure-rated pipes, making them lightweight and cost-effective. You can find DWV pipes at suppliers like US Plastic and Wallington Plumbing Supply.
Foam Core PVC Pipe
Foam core pipes offer the benefit of being lightweight while maintaining structural integrity. They are ideal for non-pressure applications, which makes them suitable for various construction needs. Prices for foam core pipes can be quite competitive.
