Awwa Class D Flange and C207 Blind Flange supplier in Mumbai

While most specifications and standards mention the content of elements used in their flanges, this standard mentions a specific content of a set of elements that are permitted to be used in the alloy. The maximum content of sulfur permissible in this alloy is 0.05 %, with the contents of phosphorus and carbon not exceeding 0.04 % & 0.29 % respectively. The Awwa C207 Hub Flange is intended to be used in applications that are light duty, involved in water such as slurry, waste management, plant piping, and waterworks.

Awwa C207 Flanges

A non-profit organization, the AWWA sets standards for the development of sustainable drinking water resources, health and sanitation facilities. Therefore, the materials that are used by the AWWA C207 Flanges Manufacturer in India would be of the highest quality, adhering to the standards. The standard also covers flanges like a blind and slip-on flange with interchangeable dimensions. The fasteners, in this case, the bolts used in the bolting of the Awwa Class D Flange along with the nuts are to match the requirement set by the specification ASTM A194. Apart from covering the minimum elemental composition in its chemistry, the standard covers the minimum tensile strength properties of the Awwa C207 Blind Flange, which is valued as high as 50,000 psi. Whereas the minimum yield strength of these parts stands at a value of 32,000 psi. While most standards do not specify the face required on the flange, this standard requires the components to be produced in a serrated face. Serrated face type Awwa Class E Flange is preferred in an application where the pressure in the piping system is to be less. The Awwa C207 Flanges can have their face type changed to flat or spiral, depending on the need of the application.
