Gantry
ultrasonic tester
THE energy industry consumes an enormous amount of
tubular products. Given the strict quality standards, new and
used pipes must be thoroughly tested before being used in
the field.
In the ‘full body phased array ultrasonic’ testing method,
several testing attributes are performed at one time, requiring a
handling system and integrated controls to effectively position
and test a wide range of pipe sizes.
Haven Manufacturing has expanded its material handling
and systems control knowledge into the oil and gas pipe
testing market.
In cooperation with ultrasonic electronics producers, Haven
has designed a gantry and rail system that will support a full
body phased array ultrasonic system. The capacity of this
system is from 2.5" to 20" diameter, and up to 48ft length.
The sequence of operation begins with measuring the length
of each pipe, to determine the end-of-pipe location. A walking
beam transfer device then positions the pipe in the test station,
while simultaneously removing a tested pipe to an exit table or
conveyor.
In the testing station, the pipe is rotated at a controlled RPM
to match the specified linear speed of the ultrasonic tester
carriage.
The combination of rotation and carriage linear speed
creates the desired test helix pattern for a given pipe diameter
and wall thickness.
Multiple servo drives control the synchronisation of the test
cycle. Manipulating up to 24,000lb of pipe at one time requires
both precision and robust construction.
