AWWA Flange Standard Supplier, Manufacturer

AWWA Flange Standards differ from ANSI (American National Standards Institute) and ASME (American Society of Mechanical Engineers) certifications in a sort way, the foremost important being their specificity, AWWA standard evaluates properties that particularly affect potable water use, as against broader industrial flange applications. Our company provides an array of AWWA flanges to satisfy your application’s specifications. The American Water Works Association, formed in 1881, was developed to identify and unify major requirements for the waterworks system. The international association serves non-profit, educational, and scientific roles to boost and support water quality and provide around the world. Members of AWWA include water treatment plant management and operations teams, water utility organizations, scientists and environmentalists, regulators, academics, and researchers within the fields of water systems and public health. This invaluable reference is now recognized globally as a key source for scientific and management insight into the water system. AWWA C207 doesn’t require a particular grade of steel, so long because the flange meets minimum standards for physical and chemical properties. AWWA Standard Flanges are developed to satisfy light-duty applications, typically requiring performance at or below 300 psi. AWWA Standard Flanges are often a good cost saver over ANSI or ASME forged flanges. These flanges, designed for oil, steam, or chemical applications and their demand for top pressure, are typically costlier and less necessary for low-pressure piping.
