ASME B16.36 class 600 welding neck orifice flanges are available in a wide range of nominal pipe sizes (NPS) to accommodate different pipe sizes and flow measurement needs.

ASME B16.36 class 600 welding neck orifice flanges are available in a variety of materials, depending on the application requirements, such as:

  • Carbon steel (e.g., ASTM A105)
  • Stainless steel (e.g., ASTM A182 F304, F316)
  • Alloy steels for high-temperature or corrosion-resistant applications.

The material selection is based on factors such as the temperature, pressure, and corrosive nature of the fluid in the system.

The ASME B16.36 class 600 welding neck orifice flange is widely used in industries where high-pressure systems and accurate flow measurement are essential, including:

  • Oil and gas (e.g., upstream production, refining, pipelines)
  • Petrochemical and chemical processing
  • Power generation
  • Water treatment and utilities

It is particularly suited for measuring the flow of gases, liquids, and steam in high-pressure systems that require reliable and accurate flow control and metering.

The ASME B16.36 class 600 welding neck orifice flange is a crucial component for high-pressure flow measurement systems. It is designed to accommodate an orifice plate that allows for accurate flow measurement by creating a pressure differential. The welding neck design ensures a robust and secure connection capable of handling high-pressure and high-stress conditions. These flanges are commonly used in industries such as oil and gas, chemical processing, and power generation, where precise flow control and measurement are essential for safe and efficient operation.
