ADVANTAGES

SUPERIOR JOINTS

  • Creates secure, leak-proof joints between ductile tubular products and fittings.
  • Mechanically joined joints will not leak, pull apart, or vibrate loose due to temperature change or pressure.
  • Superior to a welded, brazed, or crimped joint.

ROLL TO A TORQUE OR DIAMETER SPEC

  • Rolling to a torque ensures consistent results regardless of tolerance and variations of the tube OD, wall thickness, and component ID.
  • Rolling to a diameter guarantees a consistent ID of the tube. This makes it possible to “iron out”and round up the ID of the tube.

MATERIALS

  • Practically every tubing material except plastic can be mechanically joined, providing the tube is annealed or is ductile.
  • Annealed and ductile materials include: steel, stainless steel, aluminum, titanium, copper, cupronickel, iconel, etc.

ECONOMICAL, EFFICIENT, AND EASY-TO-USE

  • ECONOMICAL, EFFICIENT, AND EASY-TO-USE
  • Blades can be resharpened 1-2 times and can also be replaced.
  • Easy to use rapid-feed-retract programming.

OPERATING PROCEDURES

1) 0% EXPANSION

The tube is inserted into the flange and the mechanical joining tool is inserted into the tube.

1) 25% EXPANSION

When the tube has been rolled to roughly 25% of the total expansion required, the tube will make metal-to-metal contact with the flange.

3) 50% EXPANSION

At this point the tube metal has begun to flow into the grooved serrations of the flange.

4) 100% EXPANSION

Grooved serrations are now completely filled and the tube metal has flowed to the point of least resistance beyond the flange resulting in a mechanically formed joint that will not leak, vibrate loose or pull apart.
