GPIMS Sensors to perform guided wave inspections



In many situations, the cost of accessing a pope is much higher than the cost of inspection. This access cost can make repeat inspections with removable rings prohibitively expensive.

The environmentally friendly robust gPIMS range of sensors has been developed to be easily bonded onto the pipe, sealed and then left in place. A cable connects the gPIMS sensor to a connection box that can be located in a convenient, easy to access location.

By performing repeat inspections and comparing the results to previous inspections, operators can monitor for any change in the condition of the pope. Frequent data collection significantly improves sensitivity and reduces false call rates compared to conventional guided wave testing.

Compact Ring


The Compact ring is the latest addition to the GUL guided wave transduction system which has been designed to be lightweight and low profile. This new system has be completely re-engineered to build on everything that has been done before, while reducing weight by 35%, axial width bu 30% and radial height clearance to under 38mm.

This is an inspection system designed to tackle a wide range of inspection challenges.

Torsional wave mode transducers for guided ultrasonics

Solid Ring


The solid transducer rings are typically used for standard screening of pipes with nominal size between 2 and 8 inches in diameter. The rings are attached to the pipe by tightening the two large handles which push the spring loaded transducers onto the pipe to obtain good shear contact.

Standard rings have 2 rows of transducers to transmit torsional wave modes. Customised rings can be specifically produced in other sizes or with 4 rows of transducers to allow for inspection using both longitudinal and torsional guided wave modes.

Inflatable Ring


These transducer rings are designed to provide effective inspection capability, particularly for larger diameter pipes. Pneumatic pressure is used to press transducer modules (which are mounted onto this ring) against the pipe wall. These modules are fully interchangeable between inflatable collars of all sizes.

For sizes greater than 24-inch diameter, two smaller inflatable type rings can be linked together as detailed in a specific procedure for joining rings. Non-standard sizes (up to 60 inch) and 8-channel (non-EFC) rings can be produced to special order.

Claw Transducer


The extendable small diameter transducer or "Claw" is able to fit between closely spaced tubes where conventional rings cannot fit.

There is also a remote access option where the tool head is attached to a 2-metre-long extension arm that allows inspection of difficult to access tubes or pipes.

Different transducer spacing options are available.

Low Profile "Slinky"


The ultra low profile ring or "Slinky" was specifically designed to be able to fit around pipes that have a very limited radial clearance, like those commonly found in culverts or pipe racks. Typically less than 25mm of clearance is required to be able to mount these rings.

Due to their design, the low profile rings covers smaller pipe size range than the traditional solid rings. The standard low profile rings are configured for API nominal pipe sizes (within an API 5L tolerance).

Guided Ultrasonic Rail Scanner



The G-Scan rail instrument sends guided waves down the length of a rail to look for any areas of cross section change. The guided waves that are created in the rail are able to detect cracks and corrosion in any section of the rail, including the 'foot' and 'toe'.

Because of this ability to detect corrosion areas that are normally hidden from higher frequency methods that access the rail from the head, the G-Scan system is often used to inspect level crossings that are susceptible to foot corrosion, but are difficult to inspect without disrupting both rail and road traffic. Guided wave inspection performed from outside of the level crossing can inspect the section while the road is still fully operational; rail traffic is often not disturbed if the period between trains is long enough. The results allow you to rank the crossings, extending the mandatory lifting time for some crossings, prioritising replacement for others.

The current generation of the G-Scan uses the Wavemaker® G4 electronics and the WavePro software to collect, analyse, and report the guided wave data.
