Ultrasonic Testing Technology

"Allan Edwards is setting the pipeline repair industry standard as the most innovative provider of steel repair sleeves with the adoption of Ultrasonic Testing (UT) technology," said a company spokesperson. "The company has introduced a custom, ?rst-of-its-kind, fully-automated UT plate scanning machine and will be the ?rst repair sleeve provider to perform UT on 100% of incoming steel material."

UT is a form of nondestructive evaluation (NDE) that uses high-frequency sound waves to detect potential ?aws and laminations both on the surface and within the body of steel material for material quality evaluation.

"By implementing this form of NDE, Allan Edwards is leading the charge to elevate repair industry standards by ensuring that the quality of the repair products that reinforce in-service pipelines is not only unsurpassable but standardized," said the spokesperson. "With the new UT machine, Allan Edwards will be able to detect ?aws that cannot be observed through a visual quality inspection alone. This will provide assurance to pipeline operators that the steel repair sleeves used to reinforce their pipelines are of the highest possible quality."

"The use of UT is a common requirement among operators, but it is not the standard among steel sleeve manufacturers. This is something we want to see change," said Josh Wilson, Technical Sales Manager. "By UT scanning all of the steel that comes in and out of our warehouse, we will demonstrate our commitment to providing the highest quality product possible. We hope that others in our industry will follow suit."

Allan Edwards is adopting a highly precise form of UT known as Phased Array UT (PAUT) technology. "This method of inspection is even more accurate at ?nding ?aws in manufactured materials than conventional UT," said the spokesperson. "The ultrasonic beam assembly in the Allan Edwards Phased Array probe uses 64 individual beams, rather than a single beam as with conventional UT. By using multiple beams, the probability of ?aw detection is 10x more accurate than conventional UT."

The spokesperson continued, "The majority of pipeline operators run hydrostatic pressure tests along with a series of other tests to verify the integrity of a pipeline before it is commissioned for 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 eventually repair and reinforce the pipeline."
