Understanding Navy Flange Dimensions per MIL-F-20042

When it comes to military and naval piping systems, flange specifications must adhere to strict standards to ensure reliability and compatibility. One of the key specifications is MIL-F-20042, which governs the dimensions and requirements for Navy pipe flanges.

What Is MIL-F-20042?

MIL-F-20042 is a military specification that defines the dimensions, materials, and manufacturing requirements for flanges used in Navy piping systems. These flanges are typically found in high-pressure and high-temperature applications, including shipboard systems and military infrastructure.

Key Dimensions and Considerations

Under MIL-F-20042, Navy flanges follow standardized dimensions, ensuring interchangeability across different systems. Some of the important aspects include:

  • Bolt Circle Diameter (BCD) – The diameter of the circle formed by the bolt holes.
  • Flange Thickness – The overall thickness to withstand pressure ratings.
  • Pipe Size Compatibility – Flanges must align with specific pipe sizes as per Navy requirements.
  • Raised Face or Flat Face Options – Depending on the application and pressure class.

Why MIL-F-20042 Matters

By adhering to MIL-F-20042, naval vessels and defense-related infrastructure benefit from standardized, high-quality flange components that ensure operational safety and efficiency. Compliance with these specifications is crucial for meeting military-grade performance standards. For those working with Navy or defense-related projects, understanding these flange dimensions is essential. Always consult official MIL-F-20042 documentation for precise measurements and material requirements.
