Advanced Non-Destructive Evaluation for All Industries

Ultrasonic Testing (UT) is a versatile non-destructive technique that uses high-frequency sound waves to evaluate the internal structure and thickness of materials, without causing damage or requiring downtime. Our certified technicians use diagnostic ultrasound transducers, paired with a liquid couplant, to send sound waves through your equipment. These waves reflect at boundaries within the material, allowing us to identify cracks, voids, and other internal defects invisible to the naked eye.

By precisely analyzing these reflections, we can determine wall thickness, locate hidden flaws, and help prevent unexpected equipment failures. Ultrasonic frequencies used are much higher than human hearing—typically 500 kHz to 20 MHz—offering pinpoint accuracy for a wide range of applications.

Ultrasonic testing is commonly used for:

  • Thickness measurements on pipework to detect internal corrosion

  • Inspections of metals, plastics, composites, and ceramics

  • Virtually any solid, non-porous material except wood or paper products

Ensure the integrity of your assets without taking them out of service. Choose Hercules Crane and Lifting Supplies for reliable, advanced ultrasonic inspections—on-site or in-shop.

Frequently Asked Questions

Answers to common questions about Ultrasonic Testing (UT) and our NDT certification services.

Ultrasonic Testing uses high-frequency sound waves to inspect the internal structure of a material. An ultrasound transducer sends sound waves through the item; reflected waves are analyzed to detect flaws, measure thickness, and ensure integrity—all without damaging the product.

UT is effective on most solid, non-porous materials—including metals, plastics, composites, and ceramics. It is not suitable for wood or paper products.

UT is used for thickness measurements (e.g., pipework for corrosion detection), weld inspections, and to identify internal cracks or voids. It is valued for its accuracy, speed, and ability to inspect critical equipment without shutdown.
