Ultrasonic Testing UT is a Nondestructive testing NDT method to detect internal flaws. UT testing method uses high frequency sound waves to test materials usually in the range of 500kHz to 10MHz. Also, 10MHz to 25MHz for special applications such as aerospace.

Ultrasonic inspection is suitable for testing of Ingots, castings, forgings, rolled plates and welds. UT can also be suitable for testing raw materials, in process and finished materials. Also, one of the best NDT method for detecting flaws during inservice inspection of plants. That is to say, UT is a good NDT method for testing shafts, gears and pipelines. In addition, Ultrasonic thickness testing gives wall thickness of boiler pipes and tubes. Are you looking for UT inspection services in Bangalore?

Also, Ultrasonic testing labs are under the close monitoring of in-house ASNT NDT Level III. Therefore, before each testing, NDT Level III reviews for technique adequacy and issues proper guidance on Ultrasonic testing procedures. Every UT Level II technician will undergo proper training before engaging on job.

We also have exposure to Ultrasonic testing of critical welds. It is common to use, normal beam probes for base metal and angle beams for welds scanning. SDH blocks helps to draw DAC for angle beam. Rely on our services for Ultrasonic testing of Plates, castings and forgings.

You can also use our NDT Level III consulting services such as preparing Ultrasonic test procedures.

UT Testing NDT Agency | Bangalore

Trinity NDT is an independent NDT agency for Ultrasonic testing in Bangalore. We also serve, Hosur, Mysore, Mangalore, Bellary, Goa and Belgaum. Other projects include, UT of castings in Vijayawada, Tirupati, Vizag and Hyderabad. We offer quality services from our labs located near to you at Peenya, Bangalore in India.

Portable A-scan UT equipment available for onsite testing. B-scan provides cross sectional and C-scan plan view. Techniques include normal, angle beam and immersion testing. UT testing using DAC, DGS, TCG and dry scan for inspection of aerospace composites.

Ultrasonic inspection of stainless steel is not easy due to inherent coarse grains and non-homogenous structure. Therefore, probes with low frequency and larger diameter can yield better penetration to test stainless steels. We use high penetration methods for UT testing of stainless steels.

To ensure reliable test results, UT equipment should undergo calibration on daily basis. In house NDT Level III approves Ultrasonic procedures and also selects acceptance criteria. Can also use, customer specific UT procedures. As a result, our Ultrasonic testing labs at Bangalore have complete range of NDT inspection services.

NABL ISO17025: 2017 Ultrasonic Inspection Labs

NDT Services have NABL ISO17025:2017 Accreditation for Ultrasonic testing. In other words, we offer high quality UT testing services to our customers. Know more about our NABL accreditation and scope of testing.

Aerospace Ultrasonic Inspection | UT of Composite Materials

Ultrasonic Inspection of aerospace materials is vital for ensuring quality. For example, UT testing of Aluminium, Magnesium and Titanium components detects cracks and other anomalies. Our NDT labs can do Ultrasonic inspection of composite materials and metallic structures for Aerospace. Dry scan ultrasonic inspection is a reliable method of testing composites. Also UT finds presence of foreign materials in composites. In other words, UT is a good NDT method for testing of aerospace composites. As a result, complete range of calibration samples made of composites available to set the UT equipment parameters before inspection.

In conclusion, the labs have full facility for UT of metals and composites. In addition, we have FPI testing, Eddy Current testing MPI testing and Radiography X-ray labs.

Find Ultrasonic Thickness of Boiler tubes and Chimneys

Ultrasonic thickness testing is an effective NDT method to measure wall thickness of pipes, tubes, boiler components and chimneys. UT machines measures wall thickness with greatest amount of accuracy. Digital Thickness gauging machines available with accuracy upto 0.1mm or even less. Probes for highly absorptive materials employ low frequencies and larger diameters.

Although probes are suitable for room temperature, probes available for even high temperature boiler and heat exchanger tubes during inservice inspection. Special high temperature couplant serve the purpose. For example, Silicone grease is suitable for elevated temperatures.

UT testing with IBR approval

We are an approved NDT services company as per IBR from Inspector of Boilers, Karnataka for testing of Boiler drums, tubes and components. We also provide WPS services for IBR Boiler applications. Do you need Digital Ultrasonic thickness testing of boiler components? Call us today.

What are the Ultrasonic Testing Applications ?

Though there many applications that use Ultrasonic principles, flaw detection is prominent. Also ultrasonic principles have applications in cleaning, welding and material testing.

Other applications of Ultrasonic testing includes

  • Castings to detect shrinkage and other internal defects such as blow holes and cracks
  • Forgings and Plates
  • weld joints for LOP, LOF and other weld defects
  • Oil and Gas Pipelines
  • Tanks and Pressure vessels
  • In-service inspection of rails, wheels and axles and aircraft structures.

They may be flaws in the raw materials, may result from fabrication and heat treatment, or may occur in service from fatigue, corrosion or other causes.

What are the advantages and limitations of Ultrasonic Testing?

Ultrasonic testing Advantages:

  • It is one among three internal NDT methods to detect internal flaws
  • Detects depth of the flaws
  • Flaw sizing in UT is quite accurate
  • One side access is sufficient for pulse echo method
  • Precleaning not as important as for other NDT methods
  • Suitable for Metals, nonmetals such as composites and ceramics
  • Versatile NDT method
  • High speed of testing and suitable automation
  • No safety hazards
  • Suitable for much more than flaw detection
  • Portable UT machines are suitable for field inspections

Limitations of Ultrasonic Testing

  • Firstly, UT requires careful attention by experienced technicians to carryout testing and evaluate inspection results
  • Difficult to establish Ultrasonic testing procedures. We published free sample Ultrasonic testing procedure and test report formats on website. Download Free Sample Ultrasonic inspection procedure
  • Testing of Parts that are rough, irregular in shape, very small or thin or non-homogenous materials is difficult
  • Flaws that are present in subsurface layers may not be detectable. For such flaws it is good to use surface NDT methods such as penetrant testing, MPI testing and Eddy current testing.
  • Needs Couplant. Some times, special couplant for stainless steel and titanium alloys
  • Finally, requires reference FBH, SDH, IIW V1 and V2 blocks for calibrating the UT equipment and sizing of flaws.
