Common questions

Can you use plastic pipe for compressed air?

Can you use plastic pipe for compressed air?

The use of PVC pipe is common but not recommended for use with compressed air. The biggest reason is because it is against OSHA Regulations to utilize PVC and plastic pipes in the United States for compressed air usage. It is, however, often used because it is readily available, inexpensive, and easy to install.

What type of pipe is used for compressed air?

A great choice for compressed air piping is stainless steel because it is strong and resists corrosion. Like with copper, corrosion resistance in stainless steel piping produces a cleaner, more consistent stream of air.

What type of PVC can be pressurized?

PVC Schedule 40 Pressure Pipe features make it ideal for use in numerous industrial, commercial, municipal and residential applications. Like SDR pres- sure pipe (see page A-24) Schedule 40 has a built-in long term pressure safety factor of 2 to 1.

Can you pressure test PVC with air?

Most PVC and CPVC piping component manufacturers have statements in their literature cautioning against using air or gases to test their products. They also caution against using their product to store or convey air or other gases or failing to vent trapped air.

Can I use CPVC pipe for compressed air?

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.

Can PVC pipes explode?

PVC pipes are in danger of freezing when surrounding temperatures approach 20 degrees Fahrenheit. Eventually the pipe ruptures and sends water everywhere. Water damage from a burst pipe is expensive. To avoid dealing with burst pipes, prevent them from freezing.

How much air psi can PVC hold?

Age And Temperature Of course, PVC doesn’t just shatter or explode out of nowhere. Most consumer air compressors only compress to around 125-175 psi. This doesn’t seem like a whole lot, especially when even the smallest size PVC pipe can generally handle anywhere between 300-600 psi.

How much air pressure can PVC hold?

Is PVC safe for air compressor?

The use of PVC pipe is common but NOT RECOMMENDED for use with compressed air. However, as with many plastics, PVC gets brittle over time and can crack, break, or even shatter. The presence of air compressor oils in the line and heat from the compressed air accelerates the degradation of PVC.

What PSI can PVC glue hold?

What PSI Can PVC Glue Hold? Some PVC pipe glue can handle up to 160 PSI, but the PVC adhesive for heavy pressure is best at holding between 100-170 PSI.

At what temperature will PVC burst?

PVC pipes are in danger of freezing when surrounding temperatures approach 20 degrees Fahrenheit. Ice begins to form and gradually blocks the pipe. This blockage causes a rise in water pressure. Eventually the pipe ruptures and sends water everywhere.

What should the pressure be on PVC Air Lines?

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 PVC Air Lines = Misleading Pressure Ranges

Can you use PVC pipe for compressed air?

Pex is not specifically rated for compressed air systems and is susceptible to UV damage however, Pex-Al-Pex can deal with high pressures in compressed air systems as it has little or no vapor permeability. Can PVC hold air pressure? The amount of pressure PVC can hold varies significantly with a change in temperature.

What should the pressure be to test PVC pipe?

Applying pressure over 6 psi to the system. Using a gauge graduated to more than three times the test pressure. Failing to vent trapped air. Failure to depressurize the system. Failure to remove the test plugs with caution.

What happens if PVC air line ruptures?

If it does, then the pressure rating of your PVC pipe just dropped dramatically. 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.
