Question 1

What is a Companion Flange?

Accepted Answer

A Companion Flange, also known as a slip-on or plate flange, is a type of flange that slides over the pipe and is welded in place, allowing for a secure connection between pipes or equipment. The flange is designed to “companion” another flange, providing a leak-proof seal when bolted together with gaskets. Companion flanges are widely used in various industries like oil and gas, petrochemical, water treatment, and HVAC systems, especially in low to moderate pressure applications.

Question 2

How is a Companion Flange different from other flanges?

Accepted Answer

Companion Flanges differ from other types primarily in their slip-on design, which allows them to be easily fitted over the end of a pipe and then welded for a secure hold. Unlike weld neck flanges that have a tapered hub for structural reinforcement, Companion Flanges have a flat or slightly raised face, making them suitable for lower-pressure applications where ease of alignment and cost-effectiveness are priorities. This design also makes installation simpler and less time-consuming.

Question 3

What are the main benefits of using Companion Flanges?

Accepted Answer

Companion Flanges offer several advantages, including ease of installation, cost-efficiency, and flexibility. Their slip-on design simplifies alignment and reduces installation time, making them an economical choice for many industrial applications. They are particularly useful in systems that require frequent maintenance or disassembly, as they can be easily aligned and re-installed. Additionally, they offer a reliable connection at moderate pressures, making them ideal for systems where high-pressure handling is not a primary concern.
