World valve, flanged ends, Buna-n, sizing: 2-1/2-inch. Schedule 80 pipes are thicker, heavier designed to deal with even more PSI than Schedule 40. In the United States, Schedule refers to the density of the pipe wall and, therefore, how much pressure it will hold. In most aquaculture applications, Schedule 40 is utilized. The primary reason to utilize Schedule 80 is if it is compulsory in your area for specific applications but it can also be utilized on cold water loops to help insulate. Schedule 80 is rated at no less than 200 psi at 73 degrees F (approximately 2 inches) and is usually Gray (similar to the Schedule 40 pipe utilized for electrical conduit). The outdoors diameter (O.D.) is the same as Schedule 120 and 40, but the within diameter (I.D.) is smaller.
