Roll bending is used when large radius bends or curves are needed. It is the most commonly-used form of bending. It is used in particular with thinner wall materials, as it helps to prevent defects – such as flattening, rippling or collapse – in the bend. Mandrel bending is carried out by placing a mandrel inside the pipe or tube that’s being bent. It does not involve the use of a mandrel. It involves the tube being clamped in place, while a pressure die moves around the radius to create a bend. Also called compression forming, this technique is the original method of bending tubes. An understanding of the terminology used within the tube and pipe bending industry will help you to better comprehend the basics:Ĭompression bending is a method of bending pipes or tubes when the die in place remains stationary, while a counter die is used to bend the material round the stationary die.
