What is ultrasound testing?
Ultrasound testing is a procedure to measure & record ultrasound waves (frequency >20KHz) that propagate through the medium (Solids & Liquids) to determine irregularities related to friction in bearings and air/gas leakages. Steel, aluminium, power sector, oil & gas, manufacturing, aerospace, automotive, and many other industries use this testing mechanism to improve plant reliability..
How is it performed?
In ultrasound testing, an ultrasound transducer (a device that converts ultrasound energy to electrical energy) will be used to inspect with the help of diagnostic equipment. There are two type of transducers based on the application,
- Air borne
- Structure Borne
Air borne ultrasound inspection will be carried out to determine air/gas leakages in critical industries which will not only affect the efficiency of the plant, but also pose a greater risk to personal safety in hazardous emissions. In this testing, the transducer will be used without having to contact and can be inspected with distances upto 15 meters using different kinds of sensor like parabolic. Any kind of air/gas leakage will generate ultrasound noise due to the turbulence at the leakage location and the sensor on proper aiming will generate proportional noise levels in the diagnostic instrument which in turn help us to calculate cost loss per year with provided data by the manufacturer with the help of SONOTEC leak loss calculator.
Structure borne ultrasound inspection will be carried out to determine the irregularities related to bearing deterioration and steam trap malfunction in industries with critical rotating machinery which improve the machine component lifetime efficiency. In this testing, the transducer will be used by placing it on the component surface. Any kind of irregularities inside the roller bearing will generate ultrasound noise due to the friction between the components and sensor will generate a spectrum proportional to the abnormalities.
Features of Ultrasound Testing
- Early fault detection in the bearing diagnosis and suitable for monitoring condition of the machine.
- High sensitivity allows the detection of even the tiniest abnormalities.
- In assessing the depth of internal defects and the minor air/gas leakages, this method is more accurate than other nondestructive methods.
- Has the capability to predict the amount of leak by providing manufacturer data.
- Non-hazardous to other operations or surrounding employees and does not affect nearby equipment and materials.
- Portable and fully automated operation is possible.
- The results are immediate. Corrective measures can be implemented immediately after the inspection.
Major Industrial Application of ultrasound testing
Ultrasound testing, a non-destructive testing procedure, is perfect for finding leaks and defects without causing damage to the object or material being examined. Periodic ultrasound examinations can also be used to check for bearing health condition, lubrication management, steam trap inspection and compressor air leaks.
1.Efficient Lubrication Management:
Ultrasound can be used to lubricate machine bearings for implementing condition based maintenance rather than time based maintenance.
2.Bearing Health Monitoring & Steam Trap Inspection:
Ultrasound can be used to Monitor bearing & steam trap health condition periodically and can be helpful to plan maintenance action well advanced and improves overall plant reliability.
3.Air/Gas Leak detection:
Ultrasound can be used to inspect and record air/gas leaks at all compressed pipeline joints and will improve overall plant efficiency and provide cost saving application.

The power generation, oil and gas, transportation, and manufacturing industries employ large, expensive equipment or machinery. Nondestructive testing is used in these industries to identify whether or not important machinery needs maintenance or repairs. Technomax offers a wide range of ultrasonic nondestructive testing machines for use in these sectors. This increases machine life and reduces the need for capital expenditures to replace critical equipment. It also guards against system failures.
Nondestructive testing is available in a variety of forms, each with its own set of advantages and disadvantages. Ultrasound testing is a widely used, practical, and low-cost method. Ultrasonic testing equipment from Technomax can quickly, effectively, and economically provide an image of the material's internal structure.
