What are the R and L for on tubing benders?

The “L” is the 90° bend point and “R” is the 60°. However, if you needed to make a reversed 90° bend, you would line your 90° bend mark up with the “R”.

What are tubing benders used for?

Pipe bending is the one of the preferred metal-forming process used to permanently form pipes or tubing. Pipe and tube benders are the tools used for the purpose of bending pipes and tubes during the metal-forming projects. Woodward Fab is one of the leading manufacturers of tube and pipe bending equipment.

What are the marks on a pipe bender?

The symbols found on the Klein Tools benders are the arrow, the teardrop, the star point and angle markings. These markings are found on various sides of the bender head. The 4 most common bends to know how to make are the 90° Stub-Up, Back to Back, Offset and the 3 Point Saddle bends.

What are the types of tube benders?

What Are the Different Types of Tube Bending?

• Press Bending. The easiest and most common type of tube bending, this process involves pressing a “bend die” against the pipe to force it to conform to the shape of the bend.
• Rotary Draw Bending.
• Roll Bending.
• Mandrel Functions.
• Wiper Dies.

What are the two methods of tube bending?

Tube bending techniques may be form-bound or freeform bending. In form-bound bending, forming is dependent on the geometry of the die, such as press bending and rotary draw bending. In freeform bending, forming is reliant on the movement of the tube through the tooling, such as roll bending.

What is reverse bending?

A reverse bend occurs when the belt flexes in the opposite direction from a transfer. Reverse bends are typically used to increase sprocket wrap or for take-ups. It is good engineering practice to use the largest diameter possible for all changes in direction of belt path.

How do you measure bending tubing?

The “Measure-Bend Method”

1. Place a reference mark at the end of the tube from which you are beginning the measurements.
2. Measure four inches from the reference mark and make a bend mark to indicate the first desired bend length.
3. Bend the tube 90 degrees as described in the tech tip video.
