NDT : Guide to Nodularity Testing
Velocity Measuring Products
 

Ultrasonic testing has been used for many years to sort ductile (nodular) iron castings for proper nodularity based on sound velocity measurements.

There are currently a number of products that we can provide based on your application and budget requirements. 

Please review the below short descriptions and call us to discuss your application details and pricing. 

Dakota VX

Procedure:

  • Manually enter material thickness
  • Couple probe to material
  • Read velocity value
If material is consistent thickness - measurements in 1 second
If material is variable thickness - measurements in 1 minute

American NDT Nodularity System

Procedure:

  • Insert part in the in-tank guide
  • Part thickness and nodularity are measured untrasonically
  • Machine evaluates velocity and if acceptable a Green Light and the part is stamped.
  •  If Bad a Red Light and the part is not stamped.

Manual Load/Unload 

Typical production rate is 600 parts per hour.

 
  American NDT Kicker Nodularity System

 

Procedure:

  • Insert part in the in-tank guide
  • Part thickness and nodularity are measured untrasonically
  • Machine evaluates velocity and if acceptable a Green Light and the part is stamped.
  • If Bad a Red Light and the part is not stamped.
  • Manual Load
  • Automatic Unload into Good/Bad baskets.
Typical production rate is 900-1200 parts per hour.

The Analyst D2S is a dryer roll scanning system designed to fill the unique requirements of ultrasonic inspection on cast iron paper machine dryer rolls. 

The D2S also provides the flexibility and reporting capabilities of the AnalystTM software. Velocity and time of flight (thickness) information, insuring proper calibration at any point on the roll.

The D2S Provides the Following Functionality:

- Automated calibration

- Reduced zero error (due to wedge construction and wear)

- Multiplexed, interleaved scanning for thickness and velocity

- Fast inspection rates

- Easily viewable A-scan display

- Automated data acquisition

- Graphical display

- Automated reporting

- Access to TOF data

- Reliable trending

- Flexibility in velocity application

- View velocity data

- Reduce noise in data

The D2S system is built upon the AnalystTM software and data acquisition system. This means that the features of this system are available for B-scan inspection of anything from piping to vessels and storage tanks. Automated reporting is available for the presentation of data in several scanplan type categories. If the C1 scanner is purchased, the system will also offer the best tank wall and roof corrosion inspection system available.

RAILSCAN 125


Setting standards of performance and reliability.

For over 20 years the Railscan name has meant exceptional performance with class leading design. The latest developments in amplifier and pulser technology deliver higher levels of near surface resolution, penetrating power and excellent signal to noise ratio.

 

 

Designed specifically for Rail Testing

 Network Rail (UK) procedure and approval Narrow Band amplifiers 2 and 5 MHz G1 +ve trigger, G2 -ve trigger, (0.6 second delay for monitoring rail bottom depth).

Long Battery Life

Latest Li-Ion technology 10-16 hours (brightness dependant) Quick re-charge in 3-4 hours

Walking Stick Compatibility

Sperry walking stick. Others (e.g., NRS bi-directional walking stick) Single-shot PRF for high speed multiplexing RS232 & USB outputs for custom software systems, (e.g. Sperry palmtop with GPS)

Robust and Reliable

Sonatest's reputation for robust design and proven reliability is an important aspect of flaw detector ownership.

Down time is expensive and should be minimised to ensure maximum productivity. The Railscan is constructed to high standards using Xenoy plastics and sealed to IP67, giving excellent water resistance so it can withstand the tough environments in which operators work.

The Railscan comes with 2 years warranty, extendable to 5 years with Sonacover, and a worldwide service network.
