So, even though it may be possible to give a piece a 2D or 3D bend, a 3.5D bend may be more difficult because the tooling is not on hand. This type of bending is usually performed on a rotary draw bender for speed and precision, which requires specific tooling built for each bend. 2D = 4 inches, 3D = 6 inches, and 5D = 10 inches for a 2 inch diameter pipe. In these cases, the 2D would reference a centerline bend radius of two times the diameter. For example, on a 2 inch pipe elbow, common bend measurements may be referred to as 2D, 3D, or 5D. In some instances, a rough guide for minimum radius bending would be to use a multiple of the piece diameter. A 2” carbon steel pipe will have a different minimum radius from a thin wall 2” aluminum tube. There are many factors to take into account when determining the minimum radius such as the material composition, shape, and size. In some instances, an estimator can quickly say yes or no based on prior knowledge and bending experience. Four RAM Benders from 3T-30T (Vertical Press Bends).Often, in the rolling and bending industry, we field requests asking about the minimum radius to which we can roll or bend a piece.Unison CNC Rotary Draw Bender thru 2.50″ OD.Two Elva Induction Benders through 5.00″ OD,.Crippa CA-1042 E, Automatic CNC Tube Bending Machine.VB400 Eaton Leonard CNC 4″ Rotary Bender.VB300 Eaton Leonard CNC 3″ Rotary Bender.Fifteen Rotary Draw Benders thru 4.50″ OD.These configurations are available in most tube sizes, all materials, and most standard radii. Our standard tolerance would be “Class C”.
Quotes can be based on a tighter tolerance class. Please indicate if dimensions have critical tolerances. Need something different than these standard tube bending styles? Please contact Wagner with your special requirements.įor custom bending, quotes will indicate the Wagner Tolerance Class. When describing your bend requirements, provide Wagner with the noted dimensions and the SK style number for pricing. The details below are common shapes for tube bending that may be bent from existing tooling. The process will vary depending on your requirements for material and quantities. Wagner has equipment for roll bending, rotary bending, and induction bending. We can bend most diameters and sizes of tube - in aluminum, steel, stainless steel, brass, and bronze.
