Usage: Professionally expanding pipes – explained technically

With the FREUND downpipe expander set, you can create perfectly fitting socket connections without having to install additional form parts. In practice, you expand the pipe end so that the next downpipe segment can be inserted tightly and without tension. This is particularly helpful for repairs, custom adjustments, or when replacing individual sections in rainwater drainage – directly at the transition from gutter to downpipe or when changing direction.

How to work in practice

• Deburr and clean pipe end (for clean contact surfaces).
• Select appropriate expander diameter (e.g., 76, 87, 100, or 120 mm – depending on the set variant).
• Attach expander and expand evenly until the desired insertion length is reached.
• Check connection, readjust if necessary, and then assemble (e.g., with clamps, soldering/sealing system depending on the material).
