Rotary probes for high speed ultrasonic tube testing

Rotary Probes

Rotary Probes for high speed ultrasonic tube testing directly in the production line

Unicorn rotary probes for high speed, full body, ultrasonic tube testing

A wide range of models to suit all tube testing requirements.

Unicorn ultrasonic rotary test heads offer the following advantages over more conventional methods such as spiraling tube systems:

	High throughput test speed
	On line location
	Uncut tube ends
	Multi-orientational testing (i.e. longitudinal, transverse, oblique).
	Simpler tube handling system
	Faster size change operations

Unicorn manufacture a range of ultrasonic rotary heads for testing tube or bar products on production flow lines at high throughput speeds. Rotating the ultrasonic transducers around a pipe/bar using one of the unicorn heads offers distinct advantages over the more conventional methods of rotating or spiraling the product under test; notably

	Much faster throughput speeds are achievable
	More consistent and repeatable test results
	They can be used directly in the production line
	Reduced down time due to less stringent tube handling requirements
	Conforms to new A.P.I. specifications at realistic throughput speeds.

Details of the range of test heads are shown in the summary table. The test heads URP50 and URP100, which cover the smaller diameters, have adjustable angle transducers housed in annular chambers. In operation, the annular chamber is maintained full of water and the tube passes through close tolerance inlet and outlet guides. The URP200, URP350, URP425 and URP500 utilize the contact shoe principle which provides an advantage over the annular chambers in that much larger tube off-centre conditions can be tolerated (typically 6mm) and with a special probe shoe lift mechanism, most tube end conditions can be accommodated. these test heads can be used in on-line situations testing tubes/bars with un-cut ends straight from the production mill. All of the test heads utilize hydrostatic bearings which offer high load carrying characteristics and virtually no bearing wear. Rotary heads, of this type, have been utililized reliably over many years in an industrial environment.
