For general pneumatic and water
piping in environments exposed
to sparks from arc welding, etc.
How to measure the
minimum bending radius
Bend the tube into the U-form at a
temperature of 20°C. Fix one end and
close loop gradually. Measure 2R when
the deformed ratio of the tube diameter at
bending reaches 5%.

If the surge pressure exceeds the maximum operating pressure, it will result in damage to
fittings and tubes.
