High Quality AWWA C207 Class D Flange
The AWWA C207 Class E flanges offered by SSM are steel flanges primarily used in waterworks and wastewater treatment applications. These flanges are designed to connect pipes, valves, and other equipment in systems that require a higher pressure rating than the lower pressure ratings, such as Class B or Class D. The flange types we supply you are as follows:
- Size: NPS 4- 144 inch
- Pressure Rating : 275 psi
- Material : Typically Carbon Steel
- Types : Steel-ring flanges, Blind flanges, or Steel-hub flanges, Flat Face
Types of AWWA C207 Class E Flange
- Steel-Ring Flanges : These are flat, circular flanges made from steel, typically used to connect pipes where only a basic seal is required. Commonly used in low-stress applications where the main function is to connect pipes securely while managing higher pressures than Class D flanges.
- Blind Flanges: Blind flanges are solid discs used to close off the ends of a piping system. They do not have a central bore, which allows them to completely block the flow of fluid in a pipe. Used to terminate a piping line, valve, or pressure vessel. They are ideal for systems that may need to be extended or accessed later for maintenance.
- Steel-Hub Flanges : These flanges have a hub or neck that gradually transitions from the flange ring to the pipe, providing additional strength. The hub helps in reducing stress concentration at the base of the flange. Typically used in higher-pressure applications or where mechanical strength is crucial. The hub design is beneficial in reducing the risk of warping or cracking under high stress.

Advantages of Class E Flanges
Class E flanges, as per AWWA C207, offer various advantages in water and wastewater systems:
1. Higher pressure ratings: Class E flanges can handle higher pressures (up to 275 psi for flanges up to 12 inches), making them suitable for more demanding applications compared to lower-rated flanges like Class B or Class D.
2. Cost-effectiveness: AWWA C207 Class E flanges are generally more cost-effective than other high-pressure flange standards, such as ASME B16.5, which makes them popular in municipal and industrial water systems.
3. Easy installation: Class E flanges are designed for easier alignment and connection during field installation, reducing installation time and labor costs.
4. Wide availability: Class E flanges are highly standardized, and easy to procure and replace, which is particularly important for maintenance and repair operations.
These benefits make Class E flanges a reliable and economical choice in water and wastewater infrastructure, especially when higher pressure capabilities are required.
Summary
Class E flanges are specifically chosen when the system’s pressure requirements exceed the capabilities of lower-class flanges, making them a critical component in robust and reliable water infrastructure.

FAQ
Class E flanges are typically made from carbon steel, which provides strength and durability required for high-pressure applications.
Class E flanges can handle pressures up to 275 psi (1,900 kPa) for sizes up to 12 inches and 250 psi (1,725 kPa) for larger sizes.
Class E flanges have a higher pressure rating compared to lower classes like Class D, making them suitable for more demanding applications.
Proper alignment, sealing, and torque specifications must be followed during installation to ensure leak-proof connections and to accommodate the high pressure ratings of Class E flanges.
