Wavemaker Pipe Screening System is designed for rapid screening of long
lengths of pipe to detect external or internal corrosion as well as axial
and circumferential cracking. It can be used on a wide variety of pipes
including those that are buried or insulated. A wide range of innovative
features has been incorporated into the Wavemaker Pipe Screening System
and a user-friendly interface ensures that it is easy to use. The test
can be done while the plant is operating so disruption is minimised. Hundreds
of metres of pipe can be inspected in a day and 100% of the pipe wall
is inspected during a test. The Wavemaker Pipe Screening System is an
efficient and effective method of screening. The Wavemaker Pipe Screening
System uses a new two-ring array of probes rather than three as used in
earlier applications of this technology. |

This
has proven to be highly effective in terms of its ability to detect the
presence of corrosion but with reduced equipment capital cost. The probe
arrays can be attached to the pipe in less than one minute. Two types
of guided waves (longitudinal and torsional) are used to broaden the range
of possible frequencies and to adjust for different situations, for example
the presence of liquids. Axi-symmetric and non-axi-symmetric waves aid
in defect detection and interpretation of the results. |

> G-Scan
 |
The
G-Scan system sends low frequency guided waves along the length of the
rail that can be used to inspect many tens of metres from a single test
location. These waves are reflected from transverse and axial defects
in the rail, regardless of the orientation the defects. Internal and surface
breaking defects in the head, web and base of the rail can be detected
in a single test.
The low
operating frequency of the G-Scan instrument allows the guided waves to
pass through and inspect thermit welds for fusion-face and internal defects.
Current trial results show encouraging correlation between G-Scan results
and breaking strength of thermit welds.
