Gigabytes of inspection data, zero comparable history.
Spreadsheet workflows lose calibration provenance. Year-over-year comparison breaks down at the first column rename.
Heat-Exchanger Inspection · Native Windows
From Eddy-Current Signal to
Signature-Ready Report.
virtualTube turns tube-inspection data into auditable, decision-grade reports — built for heat-exchanger, condenser and boiler inspections in refineries, petrochemical plants and power generation.
Native Delphi software for eddy-current heat-exchanger inspection documentation and remaining-life assessment.
The Problem
Inspection data is everywhere. Decisions are still hard.
Reports take longer than inspections.
Manual copy-paste from vendor tools to Word templates eats your margin — and your inspector's evening.
Multi-vendor pain.
Eddyfi, Corestar, Rohmann — each with its own software, none of which talks to the others.
How it works
From sensor to deliverable, in four steps.
- 01
Acquire
Native multi-vendor ECT acquisition via the virtualView companion app — Ectane2, OMNI-200, Rohmann.
- 02
Analyse
3D tube-bundle visualisation, defect classification, multi-frequency correlation, calibration provenance.
- 03
Report
One-click signature-ready PDFs — full reports, list-of-results, ECT signal reports — from your project file.
- 04
Decide
Remaining-life assessment, wall-loss trending, plug/replace recommendations with 4-tier urgency colour scale.
Features
Twelve things virtualTube does that your spreadsheet can't.
Everything you need to read, document, classify and decide on eddy-current data — without leaving one application.
One Auditable Project File
Tube system, inspections, defects, calibrations and reports — bundled in one portable project file. Years of inspection history stay together, replayable and traceable.
Interactive 3D Heat-Exchanger
A fully rotatable 3D model of the tube bundle with defects colour-coded in place. Spot corrosion zones, baffle layers and damage clusters in spatial context.
Tubesheet Visualisation
GPU-accelerated tubesheet view in rectangular and polar layouts. Every tube clickable, every defect coloured by class and severity.
Multi-Layer Tubesheet Editor
Build complex multi-layer tubesheets in CAD quality. Full undo/redo, deterministic tube numbering.
Life Assessment & Remaining Life
Wall-loss tracking per tube and zone, statistical trend regression, plug/replace recommendations with a 4-tier urgency colour legend.
Campaign Comparison
Overlay defects from consecutive inspections. See exactly what grew, what's new and what stayed stable across years.
Reports in Minutes, Not Hours
Full reports, list-of-results, signal datasheets, ECT signal reports — generated automatically as print-ready PDF.
Signature-Ready Templates
Standardised templates with inspector signature, calibration evidence and defect documentation. Compliant and defensible.
Native Eddy-Current Workflow
Multi-frequency ECT, differential/absolute/mix channels, defect classification by industry standards. Purpose-built for eddy current.
Multi-Vendor Hardware
Native acquisition for Eddyfi Ectane2, Corestar OMNI-200, Rohmann PL340 and B300 through the companion virtualView.
High-Throughput Defect Editor
Debounced commits, tab-navigation and full undo history. Built for inspectors who edit hundreds of findings per shift.
Secure Server Synchronisation
Sync project files with a central, on-premise company database — encrypted, multi-user. Your data stays on your infrastructure.
Use Cases
Five scenarios virtualTube was built for.
Engineered with the input of inspectors and asset owners across the Middle East refining and petrochemical industry.
Periodic Heat-Exchanger Inspection at a Refinery
Problem
40+ exchangers on multi-year cycles, gigabytes of ECT raw data, spreadsheet workflows that lose calibration provenance.
Solution
Every campaign as a versioned project file with full calibration evidence. Multi-year trend overlays show wall-loss per tube. Signature-ready PDF + reproducible audit trail.
Multi-Probe / Multi-Frequency ECT Workflow
Problem
Bobbin + array + rotating probes across multiple frequencies. Channels need calibration, correlation, interpretation — and survival from acquisition device to report.
Solution
Native multi-frequency support, automatic support-plate filtering via frequency correlation, direct virtualView integration. Channels, samples and defect categories as first-class domain types.
Remaining-Life Assessment for Asset Owners
Problem
Plant owners need answers, not traces: 'Is this safe for another two years? Which tubes do we plug now?'
Solution
Wall-loss tracking per tube/zone across campaigns, corrosion rates, statistical life projection, plug/replace recommendations with 4-tier colour scale.
Report Lifecycle from Field to Customer Deliverable
Problem
Reports often take longer than the inspection — manual formatting, copy-paste, re-keying calibration data.
Solution
One-click generation of full reports, list-of-results, ECT signal reports and ET datasheets from the same project file. Branded, reusable templates.
Campaign-over-Campaign Comparison
Problem
'Has this exchanger degraded since 2023?' — without structured side-by-side comparison, you can't answer honestly.
Solution
Overlay tubesheets from consecutive campaigns. Defects flagged new/growing/stable/repaired. Trend tables and 3D delta-views.
Hardware Support
Speaks the language of every ECT device on your shelf.
Native acquisition through the virtualView companion. New devices integrate as clean extensions, not rewrites.

3D Visualisation in Action
Defects in space, not in spreadsheets.
Rotate the bundle. Cut through baffles. Read corrosion zones at a glance. The 3D view below is the same engine that ships in the application — try it.
- Fully rotatable tube bundle with 10,000+ tubes at 60 fps
- Defects placed at real axial position, coloured by class
- Plugged tubes shown with capped markers and DTD shortcut labels
- Tubesheets and baffles as perforated CAD-grade plates, not stand-ins
drag = rotate · scroll = zoom · right-drag = pan
Life Assessment Deep-Dive
Answer the only question the asset owner cares about.
From wall-loss per tube to a defensible plug/replace recommendation — backed by statistical regression across inspection campaigns.
- Wall-loss tracking per tube and per zone across years
- Corrosion rate calculation with confidence intervals
- Statistical life projection to user-defined wall-loss thresholds
- 4-tier urgency colour scale: monitor / plan / plug-next / plug-now
- Plug and replacement recommendations exported alongside the report

Architecture
Built native. Built to last.
Three principles that drive every design decision in virtualTube.
Native Windows Performance
True desktop application. Renders 10,000+ tubes at 60 fps. No Electron, no SPA pretending to be software.
Modular, Extensible Architecture
17 frameworks with strict layering. New hardware, new reports, new classifiers added as extensions, not rewrites.
On-Premise by Default
SQLite project files where you put them. MongoDB sync is opt-in for multi-site teams. No forced cloud.
Companion App
Live acquisition with virtualView.
For live acquisition in the field, virtualTube comes with virtualView — the multi-vendor ECT acquisition front-end. Direct hardware control for Eddyfi, Corestar and Rohmann devices. Real-time stripchart, calibration workflow, MongoDB sync back to the central project file.
