What designation is given to a hydraulic pipe that is classified as Extra Heavy?

The designation given to a hydraulic pipe classified as Extra Heavy is Scheduled 80. This classification indicates that the pipe has a thicker wall than both Schedule 40 and Schedule 20, which allows it to withstand higher pressures. The Schedule rating system used in piping allows for standardization and provides a way to specify the strength and durability of pipes for various hydraulic applications.

Schedule 80 pipes are ideal for systems that require increased strength due to higher operational pressures or other demanding working conditions. In contrast, Schedule 20 and Schedule 40 are less robust, making them unsuitable for those applications where the additional thickness of Schedule 80 is necessary. Thus, Schedule 80 is recognized specifically for its extra heavy designation, affirming its capability to handle significant pressure and enhance the longevity of hydraulic systems.
