Nuclear maintenance ultrasonic pipe measurement — Ultrasonic probe on an insulated pipe

A technician in navy coveralls wears a white hard hat, clear safety glasses, a yellow earplug and blue nitrile gloves. He presses a black-cabled ultrasonic probe against a large pipe covered in silver insulation. The black ultrasonic detector displays a measurement grid and rests on a hard case. A white couplant bottle stands beside it, while the pipe sits on green supports beneath yellow guardrails.
