What is AWWA C207 Flange?
The AWWA C207 is the “American National Standard for steel pipe flanges for waterworks service”. They are available within the size range of 4” to 144”. The AWWA is basically the abbreviation for “American Water Works Association” and is associated with all the major equipment required in the water utility services. The given standard basically have two types of flanges generally, they are: the ring-type slip-on flanges also known as the plate flanges, and the blind flanges. Both the flanges do not come with a hub and are made up of steel. Depending on its working pressure limits, the AWWA C207 Flange is divided into four pressure classes and they can be pressure rated upto 300 psi.
The AWWA C207 Flanges are primarily used in wastewater, slurry, plant piping and waterworks industries. They are available in different faces and can be used according to individual requirements. They are either forged, machined or heat treated to be manufactured.

What Is AWWA Standards?
The AWWA standards date back to around 100 years, and it was built to set a voluntary standard of minimum requirements when it comes to material, equipment, and practices related to water treatment supply. They are used by thousands of facilities, manufacturers, and distributors, throughout the world to ensure that the restaurant products have superior quality, and they are capable of giving the best performances.

What are awwa c207 flange classes?
The awwa c207 flanges are divided into four classes according to their limit of working pressure:

  • Class B - 86 psi
  • Class D- 150-175 psi
  • Class E- 275 psi
  • Class F- 300 psi

The pressure limits are for custom conditions and temperatures in various water utility services.

AWWA C110 and C153 Flange?
The AWWA C110 are ductile iron and gray iron flanges that are used with the ductile iron pipe for potable water. They are ideally used within the temperature range of 0.6 degrees C to 49 degrees C. Both the C110 and C153 are the full body specification for cast iron flanges. They both are basically made of ductile iron and come with enhanced strength and toughness. They have the same structural capabilities with a thin wall and small body. These flanges are popular for their light weight, and ease of handling. They also come with a short laying length. One can get mechanical joints for both the C110 and C153 flanges, however the flanged ends are only available for the C110 specifications.
In recent times, the compact C153 flanges are more popular compared to the full body C110 flanges. The former is more lightweight, economical, and it is known for providing much better flow characteristics.

AWWA C207 Blind Vs AWWA C207 Class D Hub Flange
The AWWA C207 Blind Flange is a steel plate with no central hub and bolted nuts through its perimeter. They are mostly placed between two flanges to stop the flow of the pipe run. They are very helpful at the time of maintenance or repair works inside the pipe.
The AWWA C207 Class D Hub Flanges are the most popular ones of the given specifications and they carry a pressure rating of around 175 psi. Their sizes fall below 12 inches. They have a central hub and help in joining the pipelines in a safe and secure way to promote proper flow in the pipeline.
