The Cherne
Steel Gauges are designed to allow gravel and debris to pass through
easily. Other gauges can get hung up on rocks and obstructions causing a
deflection test to fail even though the pipe is within deflection
tolerances causing a great expense for the contractor.
- Durable steel construction - For municipalities that require mandrels
to be constructed of steel
- Zinc plated - resists rust and corrosion
- Blade length is equal to or greater than the nominal pipe size to
conform with mandrel sizing specifications.
- Larger & Custom Sizes Available! |

CHERNE Aluminum Deflection
Gauges |
Deflection
Gauges (mandrels) are used to test flexible sewer pipes for
out-of-roundness or deflection. This testing ensures that flexible pipe
has been properly bedded and back-filled to give optimum performance.
(Per ASTM Designation D2321-89).
Cherne's adjustable aluminum gauges utilize a nine arm design to ensure
the pipe is tested accurately-often required in mandrel design
specifications. Accurately sized to .01" to meet ASTM requirements. |
The Cherne
Aluminum Fin Gauges are designed to allow gravel and debris to pass
through easily. Other gauges can get hung up on rocks and obstructions
causing a deflection test to fail even though the pipe is within
deflection tolerances causing a great expense for the contractor.
- Constructed of lightweight aluminum, gauges will not rust and are up
to 75% lighter than comparable steel models.
- Economical and versatile patented design features interchangeable fins
for various pipe sizes.
- Cherne's unique fin design allows for accurate field size verification
using a tape measurer or yardstick. Simply put two fins end-to-end and
measure the width. Add one inch to that dimension and you have the
outside diameter of the deflection gauge.
- Fins for gauges 4" through 15" have a skid size equal to the
nominal pipe size, ensuring the gauge meets regional codes. This also
guarantees that the gauge will not tip in the line.
- Fin design assembles easily without tools and all sizes fit through a
standard 24" manhole.
- Larger & Custom Sizes Available! |

Cherne's Fin Style Deflection Gauges are
designed to be field verified by inspectors without the need for a
proving ring. Simply place two fins end to end as pictured above and
measure the width. Add one inch for the mandrel and you have the outside
dimension of the gauge. Using this method simplifies the inspector's job
of verifying sizing on deflection gauges. |
