ANSI B16.36: Titanium Orifice Flanges for Flow Measurement Applications

ANSI B16.36 is a standard published by the American National Standards Institute (ANSI) that covers dimensions and tolerances for titanium orifice flanges. These flanges are specifically designed for use in flow measurement applications where precise control and measurement of fluid flow are required. Here's an overview of ANSI B16.36 and its significance in the context of titanium orifice flanges:

1. Scope: ANSI B16.36 specifies the dimensions, tolerances, materials, and markings for titanium orifice flanges used in flow measurement systems. It provides guidelines for the design and manufacture of orifice flanges to ensure compatibility and interchangeability with other components in the piping system.

2. Flange Types: The standard covers several types of orifice flanges, including weld neck, slip-on, threaded, and socket weld configurations. Each type has specific dimensional requirements and application considerations based on the piping system's design and operating conditions.

3. Materials: ANSI B16.36 specifies titanium as the material for orifice flanges used in flow measurement applications. Titanium offers excellent corrosion resistance, high strength-to-weight ratio, and compatibility with a wide range of fluids, making it suitable for use in challenging environments.

4. Dimensions and Tolerances: The standard provides detailed dimensions and tolerances for titanium orifice flanges, including flange diameter, bolt hole spacing, flange thickness, and orifice bore size. These specifications ensure proper alignment, sealing, and functionality of the orifice flange within the flow measurement system.

5. Pressure Ratings: ANSI B16.36 includes pressure-temperature ratings for titanium orifice flanges, indicating the maximum allowable pressure and temperature conditions under which the flanges can safely operate. These ratings are essential for ensuring the integrity and reliability of the piping system.

6. Marking and Identification: The standard requires manufacturers to provide marking and identification on titanium orifice flanges to indicate compliance with ANSI B16.36 and other applicable standards. This typically includes information such as material grade, flange type, pressure rating, and manufacturer's identification.

7. Testing and Inspection: ANSI B16.36 may include requirements for testing and inspection of titanium orifice flanges to verify compliance with the specified dimensions, tolerances, and material properties. This may involve methods such as visual inspection, dimensional measurement, and non-destructive testing (NDT).

Overall, ANSI B16.36 plays a crucial role in ensuring the dimensional compatibility, performance, and safety of titanium orifice flanges used in flow measurement applications. Adhering to these standards helps facilitate the selection, installation, and operation of orifice flanges within piping systems, contributing to accurate and reliable flow measurement
