AWWA C207 Class D Flange

AWWA C207 Class D Flange

We are Manufacturer of AWWA C207 Class E Ring Flange in India

The AWWA C207 is an American standard for flanges that are used for waterwork systems. These flanges are designated in different classes each having its own features. The AWWA C207 Class D Flange is the most common flange type specified in the industry. These flanges are designed in sizes of 100mm to 3600mm. They can carry a pressure rating of 175 psi for sizes that are below 12 inches and 150 psi for sizes above 12 inches. AWWA C207 Class B Flange is designed to meet the AWWA #150 drill pattern. At a suitable atmospheric temperature, the flange is pressure rated up to 86 psi. The robust AWWA C207 Class F Flange, on the contrary, is designed to meet the AWWA #300 drill pattern specifications. These flanges are designed to work in systems that are pressure rated up to 300 psi. The AWWA C207 Class E Flange is rated up to 275 psi. They are designed to meet the #150 drill pattern specification of the AWWA grade. The quality assured products are manufactured under the strict guidance of our renowned staff with the best raw materials and latest technology.

We Supply AWWA C207 Class D Hub Flange with nondestructive (NDT) Test Certificate

The AWWA C207 Class D Hub Flange is designed with a low-profile head. These flanges are slid on the pipe fixture and are subsequently welded using one or more fillet welds. They are commonly seen in applications where the stress is low in the system. An AWWA C207 Class B Ring Flange is a versatile grade that has a machined metallic ring with deep grooves engulfed in its face. The grooves rest on a metal ring that is compressed to the respective fixture using bolts. They ensure a leak-proof sealing on the connection across a wide spectrum of applications.
