AWWA C207 Class B (86 Psi) Blind-Flanges

AWWA C207 Class B blind flanges are part of the American Water Works Association (AWWA) standard for steel pipe flanges. Class B indicates the pressure rating of the flange, which in this case is 86 psi (pounds per square inch). Blind flanges are used to close the end of a pipe system or vessel opening, providing easy access for inspection, cleaning, or modification. These flanges are typically used in water supply systems, wastewater treatment plants, and other applications where AWWA standards are followed.

AWWA C207 Class B (86 psi) Blind Flanges are commonly manufactured in various materials and grades to suit different application requirements:

Materials:

Ductile Iron (Grade 65-45-12)

Carbon Steel (ASTM A105)

Stainless Steel (ASTM A182 F304, F316)

Alloy Steel (ASTM A182 F11, F22)

Material Grades:

Ductile Iron (Grade 65-45-12): This material offers high strength and corrosion resistance, making it suitable for water supply systems, wastewater treatment plants, and other industrial applications.

Carbon Steel (ASTM A105): Known for its excellent weldability and toughness, carbon steel flanges are commonly used in high-pressure and high-temperature applications in industries such as oil and gas, petrochemical, and power generation.

Stainless Steel (ASTM A182 F304, F316): Stainless steel flanges provide excellent corrosion resistance and are suitable for applications where corrosion is a concern, such as chemical processing, food and beverage, and pharmaceutical industries.

Alloy Steel (ASTM A182 F11, F22): Alloy steel flanges offer enhanced strength, hardness, and resistance to wear and corrosion, making them suitable for demanding applications in power plants, refineries, and chemical processing facilities.

Applications: AWWA C207 Class B Blind Flanges find application in various industries and processes including:

Water supply systems

Wastewater treatment plants

Chemical processing

Oil and gas production

Petrochemical industries

Power generation plants

Food and beverage processing

Pharmaceutical industries

These flanges are used to seal the ends of pipelines or vessels, providing easy access for inspection, maintenance, or modifications while ensuring a leak-proof closure.
