Fix one end and bend the loop gradually. Measure 2R when the deformed ratio of the tube diameter at bending reaches 5%. How to measure the minimum bending radius Note 1) Applicable for general industrial water. Please consult with SMC if using for the other kind of fluid. Also, the surge pressure must be under the maximum operating pressure. If the surge pressure exceeds the maximum operating pressure, it will result in damage to fittings and tubes. Note 2) The minimum bending radius is the representative value measured as shown in the left figure. Allow extra length when piping since the tube may be bent if used under the minimum bending radius. Note 3) The color of all inner tubes is black.
