Tesco Steel & Engineering is a trusted AWWA C207-07 Ring Type Flanges manufacturer, supplying high-quality flanges that meet international standards. These flanges are designed to block the end of a pipe or valve system and are used when future connections might be needed. The AWWA C228-19 standard is defined by the American Water Works Association and covers stainless steel ring-type slip-on and blind flanges. They are different from the carbon steel-based AWWA C207 series. AWWA C228-19 stainless steel blind flange are built to perform under tough conditions especially in water supply systems.
The AWWA C228-19 stainless steel blind flange comes in four classes—SB, SD, SE, and SF—each with different pressure ratings ranging from 86 psi to over 300 psi. They are made for waterworks systems and are welded at the joints for added safety. Sizes range from 10 to 48 inches in diameter. These flanges follow the same bolting pattern and outside dimensions as their AWWA C207 equivalents. Stainless steel provides strength, corrosion resistance, and long service life.
AWWA C228-19 Blind Flanges are mainly used to seal pipe ends or pressure vessel openings. They are helpful for pressure testing or when access to the pipe is needed later. These flanges are commonly seen in water treatment plants, city pipelines and other water systems. Because of stainless steel, flanges perform well in various environments. Their ability to handle high-pressure ratings makes them ideal for both small-town and large-city applications.
