Steel Inspection

At Revo Group, we specialise in the detection of corrosion across a range of assets. Our team has experience in detecting corrosion in difficult to access areas in the most efficient manner.

We use the RLS® Meter for ground line corrosion detection of steel poles.

We employ Innerspec’s technology to detect hidden corrosion and in-line quality inspections. This technology is applicable across a range of industries, including manufacturing, pipeline inspection (corrosion under pipe supports, air-soil interface, MRUT, LRUT), and steel pole and post inspections.

See below for the methods we use and offer.

RLS® Meter

We use the RLS® (Relative Loss of Section) Meter to locate and quantify corrosion in a range of steel assets. Assets the RLS Meter can be used on include steel poles, light columns and reinforcing’s that cannot be identified with a visual inspection, for example, the internal and external surfaces of the buried section, or the internal corrosion of the base and hot swaged joints.

The RLS Meter has been developed to provide safe and efficient tests without excavation to within 300mm below ground line. With proven results since 1998, this tool allows Revo Group to provide scientific and quantifiable results.

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 provides 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 does not require a 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 for ease of use and visualisation of results.

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.
