Pressure rating.
Not plumbing pvc pipe, but pvc pipe made especially for wiring.
The psi rating for schedule 40 PVC pipe is typically around 480 psi.
What schedule pipe?
Schedule of pipe most commonly refers to the thickness of the wall of the pipe itself. ex...schedule 40 PVC pipe has a thinner wall than sch. 80 PVC
Schedule 40 PVC is the type and thickness of water pipe.
PVC stands for Polyvinyl Chloride. The 40 means schedule 40, refers to the thickness of the walls of the pipe.
Schedule 40
It is the wall thickness heavier then schedule 20 lighter then schedule 80
The maximum pressure rating for a 2 inch schedule 80 PVC pipe is typically around 400 psi.
The maximum weight capacity that can be supported by a 2 inch schedule 40 PVC pipe is approximately 250 pounds.
Schedule 80 PVC pipe is recommended for applications that require higher pressure and temperature resistance, such as industrial processes, chemical handling, and underground installations.
Schedule 80 PVC pipe is used for applications that require higher pressure and temperature resistance compared to Schedule 40 PVC pipe. Common applications include industrial processes, chemical handling, water treatment systems, and underground installations where durability and strength are important.
