Pressure classes are categories used to classify the pressure rating of piping components.

• Pressure classes are used to indicate the maximum allowable working pressure for piping components.

• Common pressure classes include 150, 300, 600, 900, 1500, and 2500.

• Each pressure class corresponds to a specific pressure rating in pounds per square inch (psi).

• Pressure classes are important for selecting the right components for a ...read more
