What is the typical range of pressure ratings for PVC piping?

PVC piping is widely used in various applications due to its durability and resistance to corrosion. The typical pressure ratings of PVC pipes indeed range from 80 to 480 PSI, which can vary based on both the schedule (which refers to the wall thickness of the pipe) and the diameter of the pipe.

Different schedules of PVC pipe, such as Schedule 40 and Schedule 80, provide different levels of strength and pressure-handling capability. For example, Schedule 80 PVC, which has thicker walls, can withstand higher pressures compared to Schedule 40. Additionally, the diameter of the pipe influences the pressure rating; larger diameter pipes may have lower pressure ratings compared to smaller diameter pipes of the same schedule.

Understanding this range is crucial for proper application in plumbing, irrigation, and other systems where pressure ratings need to be factored into design and installation choices to ensure safety and effectiveness.
