Companion Flange Explained

As HVAC professionals, understanding the components that ensure the efficiency and reliability of piping systems is essential. Among these components, the companion flange plays a vital role. In this blog post, we'll provide a clear definition and explain the importance of companion flanges in HVAC systems.

What is a Companion Flange?

A companion flange is essentially a type of pipe flange specifically designed to connect with another flange, or with a flanged valve or fitting. This connection is crucial for creating secure and leak-free joints within piping systems.

How Companion Flanges Work

Companion flanges are attached to pipes using various methods, including:

• Threading: Flanges can be threaded onto the pipe for a secure fit.
• Welding: For more permanent installations, companion flanges may be welded to the piping system.
• Bolting: Most companion flanges utilize bolts to join two flanged components together securely.

This versatility in attachment methods makes companion flanges a go-to choice for many HVAC installations.

Differences Between Companion and Regular Flanges

It's important to distinguish between companion flanges and regular flanges. A regular flange is an integral part of a pipe or fitting, meaning it is manufactured as part of the pipe itself. On the other hand, companion flanges are separate components that connect two piping elements, providing greater flexibility in design and installation.

Why HVAC Professionals Need to Use Companion Flanges

Choosing the right flanges is crucial for system integrity. Here’s why HVAC professionals should consider using companion flanges:

• Flexibility: They allow for easy disconnection and reconnection of piping systems for maintenance and repairs.
• Reduced Leakage: Properly installed companion flanges can significantly reduce the risk of leaks, ensuring efficient system operation.
• Compatibility: They are designed to fit with various types of valves and fittings, which enhances the versatility of HVAC installations.

Conclusion

In summary, companion flanges are essential components in HVAC systems that facilitate connectivity between flanged parts. Understanding their function and proper installation techniques can help HVAC professionals ensure the reliability and efficiency of their systems. For optimal performance, always choose the right flange type for your specific application.
