Ansi B16.47 Class 300 Flanges

This flange type is used, normally, in high-pressure and high/low temperatures features that require an unrestricted drift of the fluid conveyed by using skill of the piping system (the bore of the flange matches with the bore of the pipe.The absence of pressure drops prevents bad outcomes as turbulence and erosion/corrosion of the metals in the proximity of the flanged joints.The tapered hub lets in a smooth distribution of the mechanical stress between the pipe and the weld neck flange and helps the execution of radiographic inspections to turn out to be conscious of manageable leakages and welding defects.The dimension of the flange (NPS and the pipe schedule) shall healthy the dimension of the connecting pipe.

Product Details

ANSI B16.47 Class 300 flanges are designed to withstand high pressure and temperature applications. They have a nominal pressure rating of 300 pounds per square inch and a maximum temperature rating of 900°F for carbon steel and 1500°F for stainless steel. These flanges are typically used in industries such as oil and gas, chemical processing, and power generation.

The dimensions and specifications of ANSI B16.47 Class 300 flanges include a bolt circle diameter ranging from 10.5 inches to 26.0 inches, a raised face diameter ranging from 7.5 inches to 24.0 inches, and a raised face height of 0.75 inches. They are available in various materials such as carbon steel, stainless steel, and alloy steel.

When selecting ANSI B16.47 Class 300 flanges, it is important to consider factors such as the temperature and pressure requirements of the application, the material compatibility with the process media, and the flange dimensions that are required to match the piping system.
