Note 1: Can be used for general industrial water. The surge pressure must not exceed the maximum operating pressure. If the surge pressure exceeds the maximum operating pressure, it will damage the fittings and tubes.
Note 2: The minimum bending radius is the representative value measured as shown in the figure on the left. The tubing may be bent if used under the recommended minimum bending radius. Please allow additional margin for flexibility.
- *Abnormal temperature rises caused by adiabatic compression can result in the tube bursting.
How to measure the minimum bending radius
Bend the tubing into a U shape at a temperature of 20°C. Fix one end and close the loop gradually. Measure 2R when the deformation ratio of the tubing outer diameter at bending reaches 5%.
