Schedule 40 Vs 80 Pipe – Which One is Best?


If you always buy accessories for your home, then you must have heard the name “schedule.” However, the term scheduling is not about time here. It’s more about the PVC Pipe thickness on the walls. Today, in this tutorial we’ll discuss the differences between the PVC Schedule 40 vs. 80 Pipes. But before that let’s grabs some information for each pipe.

Shedule 40 vs Schedule 80The PVC Schedule 40 Pipe is white in color and is used around drainage in buildings. You can find it in any local hardware shop. It’s strong, rigid and can handle pressure.

Whereas, the PVC Schedule 80 Pipe is gray in color and can handle a higher amount of pressure. You can find it’s being used in many industrial applications and heavy-duty commercials.

Now that you know, what both these pipes look like and what they do. Let’s straightaway compare them and find out which ones better for you.

Schedule 40 vs 80 

1) Color

The PVC Schedule 40 comes in pure white color, and the Schedule 80 is gray in color. This makes it very simple for us to distinguish between the two of them. However, both pipes are available in different colors as well. So make sure you check the labels before purchasing.

2) Water Pressure

Both the Pipes are highly efficient in terms of performance. It’s just each one has its benefits in various applications. If you are looking for low-pressure pipes, then schedule 40 with thin walls is the pipe for you.

However, if you are dealing with high pressure like in any industrial application or commercial area than Schedule 80 with thicker walls would work the best for you.

For calculation purposes: A 1” Schedule 40 PVC pipe has a .133 wall with a 450 PSI (Pounds per Square Inch), whereas a 1” Schedule 80 PVC pipe has a .179 wall thickness with a 630 PSI.

3) Inside Diameter of Schedule 80 vs. Schedule 40

Both the pipes have a similar outside diameter size. Although having the same outside diameter the flow is less on the Schedule 80 compared to the Schedule 40. That’s because there is a major difference in the Inside Diameter of both the pipes.

As there is more space in Schedule 40 to pass the flow it’s much faster than the Schedule 80.

4) Cost

The Schedule 80 is more on a higher price range compared to the Schedule 40. The reason for a higher price for the Schedule 80 has thicker walls which makes it more efficient compared to the 40 in specific applications. Due to higher efficiency and better performance the Schedule 80 is expensive.

5) Weight

Schedule 80 has thicker inner walls so it’s on a heavier side compared to the Schedule 40. Being heavier it’s difficult to manage and also costs more compared to the schedule 40.

Wrap Up

I hope this comparison of the Schedule 80 vs. 40 helps you make your final decision, and you end up buying the best pipe for your needs.
