Allan Edwards sets the steel industry standard with ultrasonic testing

Ensure the integrity of all steel for the repair of pipeline anomalies

The use of ultrasonic testing is a common requirement among operators, but it is not standard among steel sleeve manufacturers. This is something we want to see changed.

TULSA, OKLAHOMA, USA, November 1, 2022 / — Allan Edwards sets the pipeline repair industry standard as the most innovative supplier of steel repair sleeves with the adoption of ultrasonic testing (UT) technology. The company is launching a fully automated UT plate scanning machine, the first of its kind, and will be the first repair sleeve supplier to perform 100% UT on all incoming steel materials. UT is a form of nondestructive evaluation (NDE) that uses high frequency sound waves to detect potential flaws and laminations both on the surface and within the body of the steel material for the evaluation of the material quality.

By implementing this form of NDT, Allan Edwards is leading the charge to raise repair industry standards by ensuring that the quality of repair products that strengthen pipelines in service are not only unmatched but standardized. With their new UT machine, Allan Edwards will be able to detect defects that cannot be observed by simple visual quality inspection. This will provide pipeline operators with the assurance that the steel repair sleeves used to reinforce their pipelines are of the highest possible quality.

“The use of ultrasonic testing is a common requirement among operators, but it’s not the norm among steel sleeve manufacturers. That’s something we want to see change,” said technical sales manager Josh Wilson. “By UT scanning all steel that enters and leaves our warehouse, we will demonstrate our commitment to providing the highest quality product possible. We hope others in our industry will follow this example.

Allan Edwards adopts a very precise form of UT known as Phased Array UT (PAUT) technology. This inspection method is even more accurate in finding defects in manufactured materials than conventional UT. The Allan Edwards Phased Array ultrasound beam array uses sixty-four individual beams, rather than a single beam as with conventional UT. By using multiple beams, the probability of detecting defects is ten times more accurate than conventional UT.

The vast majority of pipeline operators perform hydrostatic pressure testing along with a range of other tests to verify the integrity of a pipeline before it is put into service. However, despite the rigorous validation testing required for the carrier pipe itself, there remains no uniform standard of testing requirements for the steel repair sleeves that end up repairing and strengthening the pipeline.

“If we as an industry have become accustomed to carrier tubing being inspected at the time of manufacture, why don’t we as an industry subject the repair material to the same level of care? said ADV Integrity’s Director of Materials Engineering, David Futch. “Allan Edwards PAUT ensures that the quality of the repair product matches the inspection standard of the carrier tube it reinforces.”

Non-destructive testing continues to prove this is a technology worth investing in as it can save businesses millions of dollars in repair costs. Industries, such as the aerospace and defense industry, have already adopted non-destructive testing technologies to test airframe structures for wear as they experience high pressure during use. The smallest breach in materials that UT testing can reveal can result in the loss of cargo, assets, and lives, making this type of technology critical for many industries to adopt.
