The pressure ratings for ductile iron pipes can vary depending on the application and industry standards. However, the most commonly used pressure ratings are Class 150, Class 200, Class 250, and Class 350.
For low-pressure applications, Class 150 ductile iron pipes are typically used. These pipes have a working pressure of up to 150 psi and are commonly used for water distribution systems, irrigation, and gravity flow sewer systems.
For applications requiring slightly higher pressure, such as industrial water supply and fire protection systems, Class 200 ductile iron pipes are used. These pipes have a working pressure of up to 200 psi.
For more demanding applications, Class 250 ductile iron pipes are suitable. These pipes have a working pressure of up to 250 psi and are used for high-pressure water supply systems, power plants, and municipal water distribution networks.
For heavy-duty applications, such as industrial water supply and oil and gas pipelines, Class 350 ductile iron pipes are used. These pipes have the highest working pressure rating, with a maximum pressure of up to 350 psi.
It is important to note that these pressure ratings are general guidelines and can vary depending on the manufacturer and product specifications. Consulting industry standards and guidelines, as well as working with qualified engineers and professionals, is crucial to ensure the correct pressure rating is selected for a specific ductile iron pipe application.
Common pressure ratings for ductile iron pipes vary depending on the specific application and industry standards. However, the most commonly used pressure ratings for ductile iron pipes are Class 150, Class 200, Class 250, and Class 350.
Class 150 ductile iron pipes are typically used for low-pressure applications, with a working pressure of up to 150 psi (pounds per square inch). These pipes are commonly used for water distribution systems, irrigation, and gravity flow sewer systems.
Class 200 ductile iron pipes have a higher working pressure of up to 200 psi. These pipes are often used for applications that require a slightly higher pressure, such as industrial water supply, fire protection systems, and wastewater treatment plants.
Class 250 ductile iron pipes have a working pressure of up to 250 psi. These pipes are suitable for more demanding applications, such as high-pressure water supply systems, power plants, and municipal water distribution networks.
Class 350 ductile iron pipes have the highest working pressure rating, with a maximum pressure of up to 350 psi. These pipes are typically used for heavy-duty applications, such as industrial water supply, oil and gas pipelines, and large-scale water transportation projects.
It's important to note that these pressure ratings are general guidelines and may vary depending on the specific manufacturer and product specifications. Consulting industry standards and guidelines, as well as working with qualified engineers and professionals, is essential to ensure the correct pressure rating is selected for a particular ductile iron pipe application.
The common pressure ratings for ductile iron pipes typically range from 150 psi (pounds per square inch) to 350 psi.
