Tube and Pipe Fabrication

The tube and pipe fabrication technology area covers sawing (band, circular, and friction) and other cutting processes, such as abrasive, flame, laser, oxyfuel, plasma, and waterjet. It also discusses forming processes, including bending and end forming. Finally, it includes a handful of miscellaneous processes, such as trimming, beveling, finning, grooving, threading, and spinning.

Tube and pipe bending trends

July 11, 2006

By:

Interviews with several tube-bending equipment-makers reveal that tube bending is becoming more complex every day, for a number of reasons. Manufacturers try to decrease material usage and go to stronger, difficult-to-bend materials with thinner walls; many manufactured items are smaller than ever before; and bends have to be smoother, especially in exhaust systems. Meanwhile, fabricators are split into two camps: High-volume OEM that are increasingly dependent on advanced controls and flexible workcells, and job shops that still get by on less sophisticated, manually operated equipment.

The wiper die's feathered edge

June 13, 2006

By:

The mechanical aspects of rotary draw tube bending haven't changed since modern tooling was developed 50 years ago. Likewise, the role of the tooling (mandrel, pressure die, bend die, and wiper die) hasn't changed. However, tube fabricators these days have many choices in regard to the tooling, especially wiper dies. Choices include material, rake angle, and whether the wiper die's feathered edge is fully machined or honed by hand.
