The ASME B16.36 class 2500 welding neck orifice flange is a vital component in high-pressure piping systems, providing robust and reliable solutions for fluid measurement applications. Its adherence to strict industry standards, combined with its durable design and high-pressure capabilities, makes it an excellent choice for engineers and industry professionals seeking optimal performance in demanding environments.

ASME B16.36 Class 2500 welding neck orifice flanges are available in a variety of materials to suit different operating environments, including:

  • Carbon steel (e.g., ASTM A105)
  • Stainless steel (e.g., ASTM A182 F304, F316)
  • Alloy steels for more extreme environments, including high-temperature or corrosive conditions.

Material selection is based on factors such as temperature, pressure, and the chemical nature of the fluid being processed.

ASME B16.36 class 2500 welding neck orifice flanges are used in industries that require high-pressure fluid control and flow measurement, including:

  • Oil and gas (e.g., refineries, pipelines)
  • Petrochemical and chemical processing
  • Power generation
  • Water treatment

They are particularly suited for high-pressure systems that need reliable and accurate flow measurement of liquids, gases, or steam.
