What is the minimum bend radius for tubing? Minimum roll bending radius is 7 x D It is technically feasible to be tighter than 7 x D but it depends a lot on wall thickness and material properties, so for safety stick to this guideline. fileslib. Generally speaking, the minimum bending radius should not be less than 2-2.5 times the outer diameter of the pipe, and the shortest straight Learn what goes into a tube bending project online now with our tube bending design guide.View our online guide for more information here at listertube.
A good guideline regarding bending die selection is to choose a radius at least three times the tube's outer diameter. This usually avoids
PREFERRED TUBE BENDING GUIDELINES Standard metal tubing size range from 1/8" O.D. to 1.25" O.D. (Tube sizes only, pipe sizes excluded.) Keep bend CLR (Center-Line Radius) to less than 6”. Distance between bend centers kept to no less than 1.5 x the tube O.D. on "U" bends and 3.50" between bend centers on "S" bends.
