Corrosion can be very costly to a business and monitoring thickness can prevent failure and damage to vital metalwork. Corrosion can lead to costly repairs, prolonged maintenance, material losses, poor performance and, if left untreated, failure. Ultrasonic thickness tools can be used in a wide range of industries such as power generation, pipes and tubing, fire safety engineering, petrochemical, shipping, rail, metals & mining and industrial sectors. As an example, in power plants, corrosion is the primary factor leading to costly and critical downtimes. Corrosion can account for up to 75 percent of a plant’s arrest time during maintenance and up to 54 percent of production costs.

What is a Thickness Gauge Tool?

Ultrasonic thickness gauges are a simple and effective NDT instruments for testing off corrosion and wall thickness. Coltraco Ultrasonics are proud industry experts in ultrasonic thickness measurement tools. Coltraco manufacture two industry leading NDT thickness gauges, ideal for the regular testing of metal work.

Advantages of Ultrasonic Thickness Measurement

1. With an UT Thickness Tester, quick wall thickness testing allows you to test a large range of metals within a short period of time.
2. Ideal for a wide range of industrial applications, such as testing pipe thickness, fire cylinders, ship hulls and storage tanks.
3. Simple enough for any operator, the range of handheld ultrasonic thickness gauges need only quick training for reliable and accurate testing.
4. The quality handheld ultrasonic thickness gauges are built to ensure they meet high standards with reliable results.
5. Using ultrasonic thickness meters allow you to go above and beyond regulatory compliance such as NFPA 25 and NFPA 13.

Best Ultrasonic Thickness Gauges Offered by Coltraco:

For your choice and budget, Coltraco offer two ultrasonic testing thickness measurement tools, the Portagauge® 3 and the Portagauge® 4. To provide you with reliable and accurate non destructive material thickness results, the devices utilises ultrasonic waves.

The Portagauge® 3 is one of the best budget thickness gauges, a single-echo portable ultrasonic wall thickness meter. Portagauge® 3 provides the great amount versatility needed to suit a diversity of safety needs. The quick, simple and hardy Portagauge® 3 allows accuracy of ±0.1mm even on corroded, challenging and some plastic surfaces. With a 50 hour battery life, measuring thickness ranges between 1.5mm to 99.9mm and a variety of verified testing materials such as steel, quartz and glass PVC, the Portagauge® 3 ultrasonic thickness measuring instrument provides the great amount versatility needed to suit a diversity of safety needs.

As well as the Portagauge® 3 Coltraco Ultrasonics also have the Portagauge® 4 which is an advanced coating thickness gauge. Offering unparalleled accuracy, the Portagauge® 4 uses triple echo technology which allows operators to inspect the underlying metal thickness, independent of any surface coatings such as paint. For applications where true metal readings and a higher degree of accuracy is required, the Portgauge® 4 is the ideal solution. The Portagauge® 4 is also an ideal ultrasonic thickness gauge for plastic. With a variety of sensor options available and underwater variants, this range of units can easily be adapted to a variety of different roles and requirements.

 

How to Use Ultrasonic Thickness Gauge?

Both ultrasonic thickness gauges are very easy to use. Simply connect the sensors to the unit, turn the unit on, apply some ultrasonic thickness gauge gel to the surface you are testing and then place the ultrasonic thickness sensor on the testing area, for an instant wall thickness measurement.

What is the ultrasonic thickness measurement accuracy?

The Portagauge® 3 and Portagauge® 4 are accurate to +/- 0.1mm in an ultrasonic wall thickness test.

What options are there for Ultrasonic Thickness Probes?

Both the Portagauge® 3 and Portagauge® 4 have a range of probe options to enable wall thickness testing from 0.1-250mm, based on your requirements.

Where are the Ultrasonic Thickness Gauges Manufactured?

Coltraco’s ultrasonic thickness gauges are manufactured in the UK.

What warranty do the thickness meters have?

The thickness meters have a 3-year warranty for main unit and 1 warranty year for the sensors.

How to calculate gauge thickness?

The results from the ultrasonic testing come in mm and with the Portagauge® 4 also in inches, meaning no calculations are needed for wall thickness results. High temperature sensors can be supplied on demand.

How do you calibrate an Ultrasonic Thickness Gauge?

The ultrasonic thickness gauges come with calibration test blocks so that you can calibrate them yourself easily.

What regulations can an Ultrasonic Thickness Gauge help me comply with?

NFPA 25 – Standard for the Inspection, Testing and Maintenance of Water-Based Fire Protection Systems
9.2.7 Tests During Interior Inspection. Where a drained interior inspection of a steel tank is required by 9.2.6.4, the following tests shall be conducted:
(3) Non-destructive ultrasonic readings shall be taken to evaluate the wall thickness where there is evidence of pitting or corrosion
(5) Tank bottoms shall be tested for metal loss and/or rust on the underside by use of ultrasonic testing where there is evidence of pitting or corrosion

NFPA 13 – Standard for the Installation of Sprinkler System
References made to NFPA 25 for regular inspection, testing and maintenance.

How are the ultrasonic thickness gauges supplied?

The Portagauge® 3 and Portagauge® 4 main units are supplied in a carrying case, with a probe, test block, instructions and ultrasonic gel.

How transportable are the ultrasonic thickness gauges?

Both the Portagauge® 3 and Portagauge® 4 are lightweight portable pocket thickness gauges.

Can the Portaguage® 3 and Portagauge® 4 be used for testing stainless steel?

Both units are ideal stainless steel thickness gauges.
