Ultrasonic inspection uses high-frequency sound waves energy to detect internal imperfections, measure material thickness and determine acceptance or rejection of a test object based on a reference code or standard. Through the use of traditional transverse (shear) wave and longitudinal (compression) wave transducers and A-scan oscilloscope instrumentation components are inspected in compliance with the applicable norms and/or customer requirements.
Our UT techniques provide instant results, and are sensitive to both surface and subsurface discontinuities throughout the entire material, and may be used with access to only one surface. Our highly qualified experts are able to provide accurate readings regarding discontinuity’s size, shape, and location.
We utilize ultrasonic testing primarily for manual weld inspection to verify code compliance during fabrication of piping systems, boilers, pressure vessels, storage tanks and structural steel welds. Our UT techniques are also useful for locating laminations and inclusions in rolled materials and to detect discontinuities in castings, forgings and for Ultrasonic Thickness Testing (UTT).
Our equipment is portable and guarantees quick and highly accurate inspections. It also offers the ability to record the discontinuity reading for later review. We have a wide selection of probes available from 1 MHz to 5 MHz, and various configurations of angles and diameters.
Ultrasonic thickness measurement is a widely used non-destructive testing technique which requires access to only one side of the test piece. It is fast, reliable and versatile technique. Ultrasonic thickness gauges work by precisely measuring how long it takes for a sound pulse that has been generated by an ultrasonic transducer to travel through a test piece and reflect from the back wall.
At NICKEL, we offer on-site thickness measurements for corrosion analysis on in-service equipment including boiler piping, process piping, pressure vessels and storage tanks. We utilize state of the art ultrasonic thickness gauges equipped with the latest through-coat technology which measures metal and nonmetallic coating thickness without the need to remove paint or coatings from tested surfaces. These advanced precision gauges have built-in data logging capabilities that allow thousands of measurements to be recorded and later transferred to the computer software for comprehensive analysis and generating immediate reports.
We hold the following UT equipment:
