Schedule 40 pipe has thinner walls, so it is best for applications involving relatively low water pressure. Schedule 80 pipe has thicker walls and is able to withstand higher PSI (pounds per square inch). This makes it ideal for industrial and chemical applications.
What is Schedule 80 pipe used for?
Schedule 80 PVC pipe is used for industrial and higher pressure water flow applications . Schedule 80 PVC pipe can handle 140 degrees F in temperature. The pipe comes in standard 10′ or 20′ sections and is available in plain end or belled end so no coupling is needed for installation.
Which is stronger PVC Schedule 40 or 80?
Schedule 80 pipe is designed with a thicker wall. This means the pipe is thicker and stronger, and as a result it can handle higher pressures. ... Schedule 40 PVC pipe is strong, rigid, and can handle pressure applications. For jobs that require a higher pressurization though, schedule 80 pipe is better suited.
What is Schedule 40 PVC pipe used for?
PVC Schedule 40 pipe is used for drainage and lower pressure water flow applications . Schedule 40 PVC pipe can handle up to 140 degrees F in temperature. Pipe lengths come in standard 10′ or 20′ sections.
Can I glue Schedule 40 PVC to schedule 80?
Yes they can be glued together . The outside diameters are the same for each pipe but the inside diameter is smaller on sch 80 pipe. Sch 80 pipe is capable of handling more pressure, hence the thicker wall. I use sch 80 for its grey apperance and thats it, sch 40 is fine for all of our applications.
Do I need Schedule 80?
The only time schedule 80 PVC conduit would be required is when the service cable is exposed to physical damage . The AHJ needs to determine if the cables are exposed to physical damage since there is not a definition of physical damage in the code.
What does Schedule 40 80 mean?
Schedule 40 pipe has thinner walls, so it is best for applications involving relatively low water pressure. Schedule 80 pipe has thicker walls and is able to withstand higher PSI ( pounds per square inch ). This makes it ideal for industrial and chemical applications.

Is Schedule 80 PVC safe for drinking water?
Schedule 80 is slightly stronger than Schedule 40. Unfortunately, most PVC is not rated for use for drinking water , not due to a high risk of toxicity, but due to the fact that it can degrade with high temperatures, UV light exposure and extremely high pressures.
Why is it called Schedule 40 pipe?
The wall thickness in that pipe diameter would hold a given pressure for a given material . Schedule 600/15 is the thickness of the pipe which would hold 600psi.
What is the cheapest type of PVC pipe?
Schedule 40 is the most common and relatively inexpensive.
How much weight will schedule 40 PVC pipe hold?
Schedule 40 1.5 inch diameter pipe can take 954 pounds of strength, and schedule 80 1.5 inch diameter pipe can take 1225 pounds. The strongest weight that can be put on something before it breaks is tensile strength.
