About Us

Plant Integrity

Established in 1997, Plant Integrity Ltd (Pi) is a technical services company that supports industrial plants and structures. Our tailored inspection solutions enable our clients to maximise operational efficiency, avoid engineering failure, and reduce inspection and maintenance costs. We specialise in the use of guided wave testing (GWT) technology for inspecting pipes in inaccessible locations, such as road and river crossings, power plant tubing, risers, off-shore topside pipework, jetty lines, and refinery pipework. In addition to guided wave inspections, we can also utilise the full range of other standard, advanced and specialist NDT techniques, and implement structural health and condition monitoring services, as well as provide third party oversight. All of which are supported by risk and reliability engineering services. We have experience in all areas of integrity management, from inspection planning, to inspection implementation, to acceptance of results, so why not take advantage of our integrated monitoring services?
