TOMEEX Schedule 40 vs Schedule 80 PVC

There are two common types of PVC pipe – schedule 40 PVC and schedule 80 PVC. Schedule 40 PVC is usually white in color and schedule 80 is usually a dark gray (they can also be found in other colors). Their most important difference, though, is in their design. 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.

You are probably most familiar with schedule 40 PVC pipe. It’s the white pipe you see used for drainage around buildings, and it can be found in local hardware stores. This pipe is best suited for drainage, irrigation, and other cold water systems. 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. Most PVC pipe and fittings have a maximum pressure rating listed so you know what it can handle. Typically this is listed in pounds per square inch or PSI.

The amount of pressure a pipe is rated for varies based on size, but a 4” schedule 80 PVC pipe for instance is rated at 320 PSI while a schedule 40 PVC pipe of the same size is only rated at 220 PSI. You can find schedule 80 pipe used most often in heavy duty commercial and industrial applications.

Pipe manufacturers usually make it gray just to differentiate it from standard schedule 40 PVC (though you should always check the manufacturer markings on the pipe to be sure).
