What Is a Tube Expander?
A tube expander is a tool used in various mechanical applications to increase the diameter of a tube.
This device operates mainly on two principles: expansion using a die and expansion using an expander. It is essential in fields such as piping, mechanical component fabrication, and construction, where it allows for the precise and efficient expansion of different types of tubes.
Typical applications include creating pipe connections, manufacturing mechanical parts, and reinforcing joints in building structures. Tube expanders come in three primary types: die-based, expander-based, and hybrid. Die-based expanders, known for their precision, are suitable for specific applications but can risk tube damage depending on the tube’s material and thickness. Expander-based expanders are safer and less labor-intensive, suitable for a wider range of applications. Hybrid expanders combine the advantages of both die and expander methods, offering versatility and efficiency.
