Schedule 40 VS 80 – 

For PVC pipes, or for any pipe, there’s a general confusion erupting debates around Sch 40 and 80. Their differences and similarities are still unknown to many. The categorization of pipes based on their thickness, a method is used called pipe scheduling. The outside diameter of both pipes is the same, but Sch 80 has thicker walls making them more expensive than Sch 40.

As different wall thicknesses are used in different applications, the ASTM society came up with the Schedule 40 and 80 systems to categorize the two common groups. Schedule 40 and 80 pipes have differences in their thickness, cost, installation, color, pressure, NPS and Outer, Inner Diameter, Applications, and use.

Sch 40 PVC pipes although capable of handling a significant amount of pressure, are more adequate for home repair or irrigation applications. On the other hand, Sch 80 PVC pipes are utilized more in industrial and chemical industries. They have thicker walls and better transport harsh chemicals at substantially high pressure. It is more expensive compared to sch 40 pipes, thus not an ideal candidate for residential applications.

Therefore if you check out the above, the Schedule 80 PVC Dimensions Table shows the exact values which you would be dealing with working on a project.

What is Pipe Scheduling? – 

Scheduling is a method of finding the measurements of PVC pipes. It’s a fabrication plan used to determine a plumbing material’s wall thickness. In non-specialists’ terms, a pipe schedule is a fixed standard for how thick a pipe’s wall must be established on how large or wide the pipe is in diameter.

As the pipe schedule value increases, so does the pipe wall thickness. A similar phenomenon takes place in Sch 40 and 80 pipes. The pipe’s wall thickness is the main criterion that changes and corresponds with the pipe’s consistently changing Inner diameter (ID). Therefore, pipe schedules don’t affect Nominal Pipe Size (NPS) and Outer Diameter (OD).

The pipe dimensions calculated using the pipe scheduling method are utilized by construction and engineering companies, plumbers, installers, and contractors. The pipe schedule is a brilliant way to understand the pipe’s compatibility with its desired application. While estimating and assessing plumbing materials and components for the job, professionals will choose the pipe size and schedule that meets or transcend the intended application’s requirements.

FAQs – 

1. What diameters does PVC pipe come in?

Ans. PVC pipes are available in sizes ranging from 1/8″ to 24″ and larger.

2. Is PVC Pipe cheap?

Ans. PVC pipe prices are lower compared to other pipes like ABS, HDPE, and PVDF, and perhaps that’s its biggest advantage over them. However, the prices of pipes vary depending on factors like pressure ratings, thickness, chemical suitability, etc.

3. Can Schedule 80 PVC to be used for hot water?

Ans. Although Sch 80 pipes are tough and rigid, it is not advisable to use them for hot water distribution because it has 57% chlorine. However, it’s fine to use it for cold water distribution.

4. Which pipes are stronger? PVC or ABS?

Ans. ABS pipes are stronger than PVC pipes when considering brute strength and shock resistance. On the other hand, PVC is known for its flexibility. ABS is better suited for underground applications where it can handle extreme warp and heat conditions. PVC works better for residential piping used for cold water distribution as it is soundproof and muffles the sound of running water.

5. How long is a normal PVC pipe?

Ans. All the PVC pipes sold are within 10- 20 feet long.
