Ductile iron pipes come in various pressure classes that are commonly used for water and wastewater purposes. These pressure classes, namely Class 150, Class 200, Class 250, Class 300, and Class 350, indicate the maximum pressure in psi that the pipes can withstand.
For instance, Class 150 pipes have a maximum working pressure of 150 psi, while Class 200 pipes can handle up to 200 psi. Class 250 pipes can withstand pressures up to 250 psi, and Class 300 pipes have a maximum working pressure of 300 psi. Lastly, the highest pressure class, Class 350, can handle pressures up to 350 psi.
The selection of the appropriate pressure class for a ductile iron pipe depends on several factors, including system design, fluid characteristics, and operating conditions. To determine the suitable pressure class for a specific application, it is crucial to consult relevant standards and guidelines, such as those provided by the American Water Works Association (AWWA).
It is important to note that these pressure classes refer to the working pressure of the pipe, which is the pressure the pipe is designed to safely contain during normal operation. To ensure compliance with the required pressure class standards, the pipes are typically tested and certified.
There are several pressure classes available for ductile iron pipes, which are typically used for water and wastewater applications. The most common pressure classes for ductile iron pipes include Class 150, Class 200, Class 250, Class 300, and Class 350. These pressure classes indicate the maximum working pressure that the pipe can withstand in pounds per square inch (psi).
Class 150 ductile iron pipes have a maximum working pressure of 150 psi, while Class 200 pipes can handle up to 200 psi. Class 250 pipes can withstand pressures up to 250 psi, and Class 300 pipes have a maximum working pressure of 300 psi. The highest pressure class, Class 350, can handle pressures up to 350 psi.

It is worth noting that these pressure classes refer to the working pressure of the pipe, which is the pressure the pipe is designed to safely contain during normal operation. The pipes are typically tested and certified to ensure they meet the required pressure class standards.
The different pressure classes available for ductile iron pipes typically range from Class 150 to Class 350.
