Our Customers Say:

“I wanted to write and applaud LTI for assisting us in calibrating some new equipment, while re-calibrating equipment that was moved. We did not have enough advance notice to schedule LTI to come in and complete the calibration / re-calibration of some of our equipment. As a result, LTI did what they could to get us out of a jam and reduce the one to two week turnaround down to two days. I wanted to let LTI know that this was very much appreciated and we value the service your organization gives us.“

Ultrasonic Inspection

Identify Defects and Discontinuities

Immersion UT inspectionUltrasonic Inspection, also known as UT Inspection, is a reliable method of detecting defects on or below the surface of materials and discontinuities in the wall thickness of tubing, pipe and other round stock. The test results from ultrasonic inspection services provide valuable information about the reliability of materials and products without causing them harm during the inspection process.

Laboratory Testing Inc. performs ultrasonic inspection services on two work shifts to meet our customers’ turnaround needs. Our lab’s capabilities include high-speed immersion UT inspection for round material, an immersion tank for inspecting oversized materials and contact UT for products and materials in other shapes and sizes.

  • Round stock from 1/8 in. to 6 5/8 in. diameter and up to 70 ft. long is inspected by our five high-speed immersion ultrasonic inspection lines.
  • Oversized round material with a diameter to 2 ft., length to 16 ft. and weight to 3000 lbs. is inspected in our A, B, and C scan immersion UT inspection tank.
  • Flat material up to 4 ft. wide, 16 ft. long and under 3000 lbs. is also inspected in our immersion UT tank.
  • Materials in other shapes and sizes are inspected by the contact UT method.

Computerized ultrasonic inspectionOur five high-speed immersion ultrasonic inspection lines and the immersion UT tank are all computerized for paperless chart recording and file retention. Our own UT inspection library of reference standards for tube, pipe, bar and plate allows us to offer quick turnaround on orders.

LTI is PRI/Nadcap accredited for ultrasonic inspection services. NDT Level 2 and Level 3 inspectors, a P&W SIM Level 3 and an NDT MIL-STD-2132 Examiner for both immersion and contact ultrasonic inspection are on staff. Our technicians are certified to ASNT SNT-TC-1A, NAS410, MIL-STD-2132 and Pratt & Whitney PWA-NDTQ to meet your industry requirements.
