What is AWWA C207 Flange?
The "American National Standard for steel pipe flanges for waterworks service" is known as AWWA C207. They come in sizes ranging from 4 inches to 144 inches. The acronym AWWA, which stands for "American Water Works Association," is primarily used to refer to all of the significant machinery needed for water utility services. The supplied standard basically only recognises two types of flanges: blind flanges and ring-type slip-on flanges, commonly known as plate flanges. Both flanges are constructed of steel and are without a hub. The AWWA C207 Flange is divided into four pressure classes, with a maximum pressure rating of 300 psi, depending on its maximum working pressure restrictions.
The wastewater, slurry, plant pipe, and waterworks industries are where the AWWA C207 Flanges are most commonly employed. They can be employed in accordance with specific needs and come in a variety of faces. To make them, they are either forged, machined, or heat treated.

What Is AWWA Standards?
The AWWA standards were developed over a century ago to establish a voluntary minimum standard for materials, tools, and procedures connected to water treatment supply. Numerous institutions, producers, and distributors across the world utilise them to guarantee that the restaurant items are of the highest quality and are able to deliver the greatest 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?
For use with ductile iron pipe for potable water, the AWWA C110 are ductile iron and grey iron flanges. They work best when the temperature is between 0.6 and 49 degrees Celsius. The full body specifications for cast iron flanges are C110 and C153. They both have increased strength and hardness and are primarily constructed of ductile iron. With a thin wall and small body, they are structurally equivalent. These flanges are well-liked for their portability and small weight. Additionally, they have a limited laying length. The flanged ends are only available for the C110 requirements, although mechanical joints are available for both the C110 and C153 flanges..
In contrast to the large body C110 flanges, the tiny C153 flanges have recently gained more popularity. The former has better flow properties and is more lightweight and cost-effective.

AWWA C207 Blind Vs AWWA C207 Class D Hub Flange
The AWWA C207 Blind Flange is a steel plate with fastened nuts running through its circumference but no central hub. To stop the flow of the pipe line, they are often positioned in between two flanges. When performing inside-the-pipe maintenance or repairs, they are particularly beneficial.
The most common hub flanges in the list of standards are AWWA C207 Class D Hub Flanges, which have a 175 psi pressure rating. They are smaller than 12 inches. They feature a central hub and aid in safely and securely connecting the pipelines to encourage proper flow through the pipeline.
