ASME B16.5 Flange

ASME B16.5 Flange

SGS Audited manufacturer of ASME B16.5 Forged Flanges in India, Check Dimensions and Sizes of ANSI B16.5 Class 600 Flanges

A flange is a device commonly used in connecting pipes, valves, and other piping equipment to form a piping system. The ASME B16.5 Flange is a protruded lip or ridge that serves to provide strength, allowing easy room for attachment and pressure transfer from the pipe. ANSI B16.5 Flange is designed in standard nominal pipe sizes from 1/2 through 24 metric inches. These flanges allow for easy access to modification, cleaning, and inspection. This Forged Steel Flange is produced at higher pressures and temperatures. These flanges showcase lower surface porosity while having a finer grain structure. They have enhanced strength and superior hardness. We are a Forged Flanges manufacturer who follow all international and national standards while producing some of the best flanges in the market today.

Check Sizes and Pressure Rating of ANSI B16.5 Flanges in Class 900 to Class 2500 Range

The ASME B16.5 material covers different dimensions, tolerance, and methods for designating different pipe flanges. The material flanges are available in pressure classes of 150 to 2500. ASME B16.5 Class 300 is designated to work in low pressure and temperature conditions. The items within this grade are designed in different types of flanges to be used across different applications. The ANSI B16 5 class 900 flange is rated at 2220 PSIG at temperatures up to 100 degrees F in these harsh environmental conditions. As the temperature in the ANSI B16 5 class 900 flange increases, the pressure-holding capacity of the grade drastically decreases. The class 900 flange is designated for a moderate pressure rating. The ANSI B16 5 class 1500 flange can handle high pressure setups. These flanges are rated at 3705 PSIG at 100 degrees F.

Uses Of Pipe Flanges

  • The main use of asme b16.5 flange is to connect valves, pipes, pumps, and other equipment to make a pipeline system.
  • Usually, ansi b16.5 flanges are threaded and welded (two type), can connect two steel flanges by bolting them with gaskets.
  • Forged Flanges are available in many types like socket weld/ blind/ weld neck/ slip-on flanges, etc.
