Can you use Schedule 80
Nominal Pipe Size
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. "Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – "2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2-inch diameter hole through the center).
Polyvinyl chloride
Polyvinyl chloride is the world's third-most widely produced synthetic plastic polymer, after polyethylene and polypropylene. About 40 million tonnes are produced per year.
What is schedule 80 PVC pipe?
Schedule is a type of categorization that is used in other types of pipe also. For instance, there is a schedule 80 steel pipe. What is schedule 80 PVC used for? Because schedule 80 PVC is a thicker pipe, it is usually is used for applications that are commercial or industrial in nature.
Can PVC pipe be used for compressed air lines?
No, PVC and CPVC pipe should not be used for compressed air lines. Here is what the manufacture has to say about it. WARNING! The use of plastic piping with compressed air or gasses can result in severe bodily injury or death.
What happens if you only have one schedule 40 PVC fitting?
In other words, a pipe line built entirely from schedule 80 PVC pipe and fittings that contains only one schedule 40 PVC fitting is only able to handle as much pressure as that thinner schedule 40 fitting. If it is too weak to handle the pressure in the line, the line will fail (ie. Crack, leak, or burst).
What happens if you put air in PVC pipe?
The presence of air compressor oils in the line and heat from the compressed air accelerates the degradation of PVC. These failures, combined with air under pressure, are potentially fatal due to the airborne, razor-sharp shrapnel.

What happens when PVC is over pressured?
If PVC pipe is over pressurized that pipe can experience a catastrophic failure. It does not just form a bubble and then pop, which is what happens to polyethylene tube when you overpressure that material. When a PVC pipe lets go, it shatters. All of a sudden you could have sharp plastic shards of pipe flying and ricocheting all over the workshop or plant.
What happens if you overpressurize PVC?
If you over pressurize PVC pipe, your pipe could undergo catastrophic failure, with disastrous and life threatening results. It does not just form a bubble and then pop, which is what happens to polyethylene tube when you overpressure that material. When a PVC pipe lets go, it shatters.
What happens if you drop pressure on PVC pipe?
All of a sudden, a 120 PSI air pressure inside the pipe when the outside air is cool, will cause ruptures as the pressure rating for that PVC pipe has dropped below the danger level due to the temperature rising where it has been installed.
What is the pressure of PVC pipe?
PVC pipe is poly-vinyl chloride. If you look at the manufacturers markings on the pipe, it will often say that the pipe is pressure rated for 140 PSI or 150 PSI, somewhere in that range, depending on the manufacturer and the pipe diameter. Regular PVC pipe – not reliable for compressed air service.
What happens when PVC pipe temperature is high?
When PVC pipe temperature is high the rating of the pipe (or how much pressure it can hold) drops and raises the possibility of an explosion. It cannot hold pressure as well as other materials for piping.
Is PVC pipe good for air lines?
Since PVC pipe appears to be very well priced when compared against other materials for plumbing and on top of this, the installation is pretty easy with typical, around-the- house plumbing tools. PVC is cheap, readily available and works well with a variety of applications including transporting liquid.
Is polyethylene tubing a plastic?
Yes, polyethylene tubing is a plastic. It is a different family and formula than PVC however, and I can tell you from personal experience, that if you over pressurize the P.E. Tube, all that happens is that a bubble forms at a weak spot, the bubble grows, and eventually, the bubble pops rather than completely shattering.
Why is it important to select the correct type of PVC?
Since each type of PVC has different costs, it's important to ensure that the PVC you choose for your project is not only durable enough for the use-case but also affordable; overengineering can cost real money.
What is the temperature of PVC pipe?
As PVC is heated, the pipe and fitting's max pressure rating is derated. Since the properties of PVC change depending on the temperature, 73°F is used as the standard temperature for which PVC pipe and fittings are rated; the further the temperature gets from the 73°F rating point, the more the properties of the PVC change from their listing.
What is PVC pipe made of?
Since PVC is a thermoplastic, it is formed from resin under heat to create the pipe and fittings that comprise Schedule 40, Schedule 80, and CPVC. As you may have guessed, that means that PVC can't handle extremely hot temperatures; the pipe will begin to melt at a certain point.
