Strategies for Successful Heat Exchanger Tube Plugging

2025-02-13T11:20:40-05:00

Plugging leaking tubes in heat exchangers is a critical maintenance task. However, this seemingly straightforward procedure can present a multitude of challenges that can impact both the success of the plug and the overall maintenance process. These challenges include creating a secure seal due to suboptimal tube conditions, limited reach and accessibility, and the availability of suitable plugging materials.

The Evolution Of The Tube Plug

2022-07-27T07:58:58-05:00

There have been many variations of the tube plug over the years in an effort to achieve maximum sealing area and to control the method in which it is installed. While each of these plugs are still commonly used today, they were designed to overcome various challenges operators have had over the years.

Not having a compatible tube plug material can result in leaks, costing hundreds of thousands of dollars or more in lost production and revenue. When plugging a “leaker” (leaking tube), it is good practice to use plugs that are the same or a compatible material to the tube in order to meet industry requirements and engineer specifications and avoid galvanic corrosion.
