AWWA C207 Class D and E Blind Flange

Pressure Rating Of Stainless Steel AWWA C207 Class E Flange, Specification List Of Carbon Steel Awwa C207 Flange Material.

Unlike the other specifications that have certain rules with regards to the materials used in the manufacture of flanges, the AWWA, has a specific set of minimum physical and chemical properties. In addition to the minimum yield strength and tensile strength of the Stainless Steel AWWA C207 Class D Flange, the specification also mentions the contents of carbon, phosphorous as well as sulfur. The chemistry of Awwa C207 Flange Material must contain a Maximum Carbon content of about 0.29 %, whereas the maximum content of Phosphorus is around 0.04 % and lastly the maximum permissible content of Sulfur is 0.05 %. It is customary for AWWA C207 Class E Flange manufacturers to stamp these flanges with several details including the trademark, class, nominal size, material designation as well as heat. This standard also mentions tolerances for the AWWA C207 Blind Flange Dimensions.

Typically, the use of these flanges is meant for applications involving waterworks. Unless a raised face is mentioned while placing the order, a manufacturer will supply the AWWA C207 Steel Pipe Flanges that are produced with a flat face. If required by the buyer, the producer could also arrange for the test reports of the AWWA C207 Flanges.
