Technical Insight | Why Alignment Control Is More Important Than Pulling Force Alone in Large Tube Bundle Extraction

In heat exchanger maintenance, many people first focus on the rated capacity of a tube bundle extractor, such as 25T, 45T, 65T, 85T, or even higher. However, in real engineering applications, whether a machine performs well does not depend only on maximum pulling force. For large shell-and-tube heat exchangers, alignment control, stable support, and smooth movement during extraction are often more important than the pulling force rating alone.

The deformation of the tube bundle will have a significant negative impact on the efficiency of the extraction machine, which is mainly reflected in the following aspects:

The deformed tube bundle will interfere with the clamping mechanism or guide device of the pumping and loading machine, increasing the frictional resistance, causing the pumping speed to decrease, and even making it impossible to extract or load smoothly.
