A pressure rating refers to the qualified operating pressure which is recommended for a component or a system by the manufacturer. The maximum working pressure of a 12" steel having a schedule of 40 at 100 degrees Fahrenheit is 855 psig.
A pressure rating refers to the qualified operating pressure that is recommended for a component or a system by the manufacturer. The pressure rating of 12 schedule 40 steel pipe is 370 psi.
The difference between schedule 40 and 80 pvc is the wall thickness and schedule 80 is thicker then schedule 40 so the higher the schedule number the thicker the wall of the pipe thus can hold more pressure.

The maximum pressure per schedule for GI pipes varies. For instance, a schedule 40 for a black poly pipe would be 200 psi.
Schedule 40 welded carbon steel pipe (black) is rated at a working pressure of 150 psi. It should be printed on it. Schedule 80 welded is rated at 300 psi. If U want higher rated piping you must use seamless (not welded) pipe. Hope this helps!

What does the schedule have to do with the material as schedule is the wall thickness Schedule 10, 20, 40 80 and 120 (XXH) The Schedule is telling you the wall (INTERNAL) thickness 10, 20 40, 80 and 120 XXH Whether it be steel, brass, galvanized and wrought ` About the pressure capacity, it is not the same because every material such as steel, brass, galvanized or wrought has a different strenght of materials.

That would depend on the temperature "Temperature pressure relationship" and the fittings used
pressure rating up to 40 mm will be 20 bars and higher sizes it will be reduced as PN-15.
schedule 40 is thicker than schedule 20
