Operation
Test the Coupon
Allow the coupon to come to temperature in a 73°F ± 5°
(23°C ± 2.8°) environment.
IMPORTANT:
In the field, a truck cab or temporary building can be used to
bring the coupon to temperature.
Insert the coupon into the guided side bend tester, laying flat with the
beaded section directly under the top bar, and on top of the side bars.
The alignment here is critical so as to test the right portion of the pipe.
Misalignment can cause flawed results and errors in testing.
Turn the pressure release valve to close. Pump the hydraulic pump handle at
a medium speed, keeping a constant pace.
Stop pumping the handle when the coupon has been bent up to the angle
required by the test specifications. The bend angle label on either side of the
tester will help determine if you reached the desired bend angle. The yellow
label will indicate the exterior bend angle and the white label will indicate
the interior bend angle. If there is no other guidance or specification we
recommend a bend angle of 90°-120° (yellow label) or 90°-60° (white
label).
NOTICE:
Do not exceed specified bend angle. Excessive pressure will
damage the tester and/or invalidate results.
Release pressure in the tester by opening the pressure release valve.
Remove the coupon from the tester.
