Talcyon Pte Ltd

TMR is an end-to-end inspection software solution that integrates with the hardware of inspection equipment. This incorporation creates a simpler workflow for inspection jobs from the creation of inspection layout, inspection data management, automated graphs and charts, and report generation, thus, increasing productivity.

Featuring patented Acoustic Pulse Reflectometry (APR) technology, APRIS is an advanced, yet easy-to-use tool that overcomes the limitations of many conventional inspection techniques. With its simple operation, interactive analysis and report generation, it offers enhanced user experience. Providing reliable inspection of even the most challenging tube sizes and configurations, APRIS increases inspection cycle efficiency and operational cost savings.

Key Features

1. Adaptable for tubes of up to 4″ inner diameter, any shape or material.

• Any shape: D-type , Finned tubes , Multiple bend tubes, Twisted Tubes, Spiral Tubes, U-tubes
• Any material: Ferrous metals, Non-ferrous metals, Graphite, Plastic

2. Ultra-fast, non-invasive inspection

• Less than 10 seconds per tube
• If the tube is less than 6m, inspection takes only 5 seconds!
• No need for inventory of consumable probes.

3. Less expertise required

• Easy operation with minimal training.
• Computer-based data interpretation and signal analysis.

Using Acoustic Pulse Reflectometry

Acoustic Pulse Reflectomery (APR) is a specialised technology that measures the ensuing reflection from the surface abnormalities by sending sound pulses down the tube using air as a medium.

Any changes in the cross sectional area in the tubular system generates a reflection. These reflections are generated from the change in geometry in the tube when sound travels down the tube.

Each defect has it own signature and our patented algorithms identify, classify, and report the location and size of defect.

Pre-requisites to carry out APR inspection

• Tubes to be cleaned and dried (No water stagnation)

Flipsides of APR:

• Defects in the outer diameter can’t be detected
  
• Inept to detect the defects under deposits/scales
• Cracks under pressure (Closed Cracks) shall not be detected

International Standards

• ASTM E2906/E2906M-18: Standard Practice for Acoustic Pulse Reflectometry Examination of Tube Bundles
• ASME BPVC.V-2019: Article 18-Acoustic Pulse Reflectometry (APR) Examination

How It Works?

• Map Tube Sheet

Upload a photograph or schematic diagram of the Heat Exchanger onto the APRIS software. Create a map of the tube sheet. Assign a number to each of the tube openings. A tube sheet gives the software a graphic representation of the Heat Exchanger. As such, it will help you track which tubes have already been measured – empowering you to work efficiently. 

Set-up Inspection Parameters

Set the inspection parameters based on the physical attributes of the tubes. This includes the tube length, diameter, and wall thickness.

• Take the Measurement
  

Follow the tube sheet map and insert the probe of the APRIS handheld device into each tube opening. This will take about 10 – 15 seconds per tube. The LED light on the APRIS device will indicate when the measurement is complete. The software will then highlight the next tube to measure.

Set Inspection Thresholds

Once measurements have been taken, a reference measurement is calculated based on statistical signal processing, considering statistical deviation of tube signals and the presence of ambient noise. Any measurement beyond that deviation is a potential flaw. In addition, the APRIS software enables the Heat Exchanger owner to determine thresholds for each type of defects such as holes, blockages, pitting and erosion, depending on the sensitivity of the given application (e.g. the diameter of the hole, percentage of the cross-section reduction, percentage of the wall loss, etc.). Only those measurements that exceeds the defined threshold are reported as flaws.

• Analyse Data and Generate Report
  

The raw data (i.e. signals) collected by the system is interpreted and presented to the inspector for review and verification. This entire process is performed automatically by APRIS software that works on sophisticated Artificial Intelligence (AI) based on algorithms. It generates a final report (PDF) containing summary information, including tabular reporting, charts and screenshots of the deflected flaws.

Tube Mapping Software (TMS) is a solution designed specifically to produce an accurate layout and labelling of tubes on a tube sheet. Collectively needed for tube inspection and maintenance reporting, TMS offers user-friendly features that allow companies to carry out their reporting faster and more efficiently.

Key Features

1. Hassle-free. Start mapping with ease by having multiple methods of inputs.

• Map using a photograph.
• Map using a technical drawing
• Manual mapping using rows and columns (when photographs and drawings are unavailable).

2. Automated mapping. Manual editing is available to fine-tune the output.

3. Custom map building using Grid (angle, row&column).

• 45 degrees
• 90 degrees
• 30 degrees
• 60 degrees

4. Line select – select a row of mapped tubes.

5. Mirroring technique.

6. Minimap.

7. User-friendly advanced software design; easy to use with a quick tutorial.

Integration with Reporting Functionalities

TMS works well with reporting softwares to translate data into presentable and easy-to-read formats.

• Set-up Inspection Parameters
  

Set the inspection parameters based on the physical attributes of the tubes. This includes the tube length, diameter, and wall thickness.

• Edit graphical representation
  

Make sure all tubes are detected and correctly mapped.

Manual editing can be carried out in this step to increase accuracy. If some tubes are left undetected, you may select ‘Add tubes’ to add the tubes that are not detected by the software. Similarly, you shall select the ‘Delete Tube’ option to delete tubes that were falsely detected by the software.

• Tube ordering
  

Order the tubes by row-column attributes.

Choose the First Tube to define the first tube and next choose Define Direction by selecting two adjacent tubes.

Once done, click Order Tubes and each tube will be ordered by Row (R), Column (C), Zone (Z) and respective Tube Number (N).
