Steel Inspection

We specialise in the detection of corrosion in difficult to access areas in the most efficient manner.

The RLS® Meter is designed and tested specifically for ground line corrosion detection of steel poles.

The Innerspec gear specialises in detection of hidden corrosion and in-line quality inspections. It is applicable across many industries, but mainly manufacturing, pipeline inspection (corrosion under pipe supports, air-soil interface, MRUT, LRUT), and steel pole and post inspections.

Take a look at the methods we use and offer.

RLS® Meter

The unique RLS® (Relative Loss of Section) Meter is developed specifically to locate and quantify corrosion of steel poles, light columns and reinforcing that cannot be identified by visual inspection. i.e. internal and external surfaces of the buried section, and internal corrosion of the base and hot swaged joints.

  • Test without excavation to within 300mm below ground line
  • Efficient
  • Safe and simple to use
  • Portable
  • Scientific and quantifiable
  • Proven since 1998

An eddy current-based technique developed in the United Kingdom and in use for over 13 years overseas, the RLS® is a NDE method that allows the operator to quantify corrosion in the critical zone of a pole without excavation.

The RLS® technique is a dry coupled system that will provide a cost-efficient assessment of the column. The results obtained estimate the percentage loss of section allowing the columns to be classified for either replacement or retesting at a scheduled interval.

Combined with a simple classification matrix, asset managers can appropriately schedule replacement knowing that the technique is validated on over 1.2 million poles in the United Kingdom, Singapore, Australia, New Zealand, Indonesia and Hong Kong . In Singapore it is the only technique approved to test embedded steel poles and CMT (Testing) Limited in the UK is the first and only organisation to be awarded UKAS Accreditation to ISO 17025 for testing lighting columns using the RLS® technique.

MRUT

MRUT (Medium Range Ultrasonic Technique) with EMAT is perfect for;

 

  • Full-length pipe inspection
  • Full-depth inspection of steel poles
  • Air-soil interface inspection
  • CUPS inspection (corrosion under pipe supports)
  • Inspection around elbows
  • Tank wall surveys
  • Any hard-to-reach areas
  • Full-volume, full length inspection of pipes (particularly good for slurry pipes because you don’t need to guess where the internal wear is concentrated)

Innerspec – EMAT

EMAT technology uses the interaction between electrical and magnetic fields to generate ultrasonic waves within the steel, rather than shoot them in like standard piezo ultrasonics. This means no couplant is required.

A full range of wave modes can be generated including surface, lamb, angle beam, normal beam, guided waves, vertical and horizontal polarised, etc. This allows for a wide range of inspection types with the same equipment. EMAT is the only technology that can generate shear-horizontal waves, which are hugely beneficial for guided waves as they do not attenuate as much due to lower surface interaction.

The no-contact capabilities mean that the tools can be used on surface temps up to 200 degrees Celsius as standard, with some thickness probes capable of going above 750 degrees Celsius (air and water cooled).

Because it doesn’t require couplant, the applications in QA in manufacturing are endless and it is used all around the world in steel manufacturing, steel fabrication, and for weld quality checks in vehicle body part manufacturing.

VOLTA

The Volta device is a ground-up, next generation portable device to power the mobile inspection probes from Innerspec. It has a great form factor, with the main power unit mounted in a backpack, and a new interface and tablet form factor for ease of use and visualisation of results.

Volta table
One of the biggest benefits of the Volta though, is its two-channel design that allows directional guided wave analysis. Soon, it will also have some advanced probes and software upgrades that will allow it to be used for LRUT as well, giving higher accuracy, longitudinal resolution and detection of smaller defects compared to conventional LRUT.
