Schedule 80 Pipe Chart and PVC Pipe Sizes – Dimensions and Specifications

Understanding Schedule 80 pipe and PVC pipe sizes is crucial for industrial, commercial, and residential applications. Schedule 80 pipe is designed with thicker walls, making it more durable and pressure-resistant compared to other types of piping.

What is Schedule 80 Pipe?

Schedule 80 pipe has thicker walls than Schedule 40, providing enhanced strength and higher pressure ratings. It is widely used in industrial applications, chemical processing, and water distribution systems where durability is essential. When considering PVC pipe sizes, it’s important to compare them with Schedule 80 pipe for the right application.

Why Choose Schedule 80 Pipe?

Higher Strength and Pressure Rating – Compared to Schedule 40, Schedule 80 pipe withstands greater pressures, making it ideal for demanding applications.
Corrosion and Chemical Resistance – Schedule 80 pipe and PVC pipe sizes offer excellent resistance to chemicals, rust, and corrosion, ensuring long-term durability.
Versatility in Applications – Commonly used in industrial plumbing, wastewater systems, irrigation, and chemical transport.
Longevity and Cost-Effectiveness – Schedule 80 pipe and PVC pipe sizes are durable, lightweight, and affordable alternatives to metal pipes.

How to Choose the Right Schedule 80 Pipe?

When selecting Schedule 80 pipe or determining the right PVC pipe size, consider the following factors:

Outer diameter (OD) and inner diameter (ID) – The required Schedule 80 pipe or PVC pipe size depends on the flow rate and pressure conditions.
Wall thickness – Schedule 80 pipe has thicker walls, increasing strength while reducing the inner diameter.
Application requirements – Ensure the chosen Schedule 80 pipe or PVC pipe size meets your project’s specifications.

Conclusion

Having an accurate Schedule 80 pipe chart and understanding PVC pipe sizes is essential for selecting the right pipes for your needs. Whether for industrial, commercial, or residential use, knowing the correct Schedule 80 pipe dimensions ensures a safe and efficient system design.
