AWWA C207 is a pipeline flange standard developed by the American Water Works Association. The steel hubbed flange is one type of flange with a protruding neck, known as a flange neck or flange pipe, which can provide better support and connection strength, making the neck flange more stable and reliable in high-temperature, high-pressure, and vibration environments.
Size and Pressure Rating
According to AWWA C207 standard, the size range of steel hubbed flanges is from 4 inches to 72 inches, and common pressure ratings can reach Class D (175 psi) and Class E (275 psi).
AWWA C207 Slip on hubbed flanges are widely used in water supply and drainage systems, including the following aspects:
1. Tap water, sewage treatment plants, and industrial wastewater treatment
2. Water treatment and distribution
3. Irrigation and drainage
4. Landfill and treatment
Advantages and Disadvantages
1. Good stability: The steel hubbed flange has good support and connection capabilities, making it very stable and reliable in high-temperature, high-pressure, and vibration environments.
2. Easy installation: Installing the AWWA C207 steel hubbed flange is very convenient, just place it on both ends of the pipeline and tighten them with bolts.
3. Easy to maintain: Due to the relatively easy installation and disassembly of the AWWA C207 steel hubbed flange, it is very convenient to replace or repair this connection method.
1. Higher cost: Compared to other pipeline connection methods, AWWA C207 steel hubbed flange has a higher cost.
2. Attachment restriction: The holes on the steel hubbed flange are used for installing accessories, but these accessories must comply with the specifications and requirements of AWWA C207 standard.
The AWWA C207 steel hubbed flanges are available in stainless steel as well as carbon steel A105 flanges.
Overall, AWWA C207 steel hubbed flange is a very common pipeline connection method, widely used in water supply and drainage systems, with advantages such as good stability and easy installation and maintenance
