Tube forming for connections

Tube forming basics glossary

Tube forming basics – circa 1970 – click to  view pdf

Detroit Tube Products can form tubes in a great variety of ways — not just bending! Tubes are all about connections; they enable fluids to move from one place to another. How do the finished parts get assembled? In a factory, in the field, as part of a machine build or in a skyscraper construction? Those factors influence how the parts are designed to attach to each other. This means that frequently, we’re shaping the connections between tubes/parts instead of welding a hard connection.

What kinds of tube forming for connections are we talking about? We found this old (as in 1970) guide that shows the basics and thought we’d share it as a series of topics. It’s a little bit yellowed from age but still valid. Here you can see swaging, expanding, beading, flaring, and flanging very simply represented.

Different Aspects of Tube Forming and Shaping

Sometimes tube forming and shaping aren’t just on the end — take a look at these straight tubes with a bead far in from the end. Here are some examples of expanding, hose beads, and flaring from what we’re making right now. Materials are better and more reliable now, and we continually refine our tools, so the end products are better than in the last century, but the vocabulary’s the same, so enjoy the retro guide!
