Overview

Product overview

The Advanced Tubing Inspection Solution brings Eddyfi Technologies’ tube inspection equipment and software into a coordinated workflow, from acquisition through final reporting. Ectane 2 and Magnifi form the acquisition and software core, while Probot controls probe movement to support consistent signals, encoded data and precise defect locations.

Different probes address different inspection challenges. DefHi eddy current array probes detect and size axial and circumferential cracks in non-ferrous tubes without interference from external fins. NFA probes provide initial screening of aluminum-finned carbon steel tubes, with IRIS used for subsequent proof-up. Flexible ECT and RFT probes enable inspection of straight and bent tube sections in a single pass, subject to their respective bend-radius capabilities.

Magnifi Assisted Analysis checks acquisition quality and pre-screens data using detection windows, helping analysts concentrate on potential defects. A live two-way link with TubePro transfers tube lists and tracks inspection progress. TubePro creates tubesheet models from pictures or drawings and produces reports that can compare inspection datasets and include an interactive 3D exchanger model.

The solution is intended for heat exchanger assessment in oil, gas and petrochemical assets, including refineries and chemical plants. Probot supports ECT and RFT inspection as well as IRIS through a water-feed slipring; its acquisition speed depends on the inspection technique.

Key Features

Key capabilities

Controlled probe movement

Probot pushes probes up to 100”/sec and supports data recording at technique-dependent optimal speeds up to 70”/s.

Single-pass U-bend inspection

Flexible ECT and RFT probes inspect straight and bent tube sections in one pass within their stated bend capabilities.

Array crack detection

NFA and DefHi array probes support crack detection, with DefHi sizing both axial and circumferential cracks in non-ferrous tubes.

Consistent encoded data

Encoded acquisition and constant probe speeds make data more uniform for analyst review.

Assisted analysis

Magnifi validates acquisition and pre-screens data to identify potential defect locations and mark tubes without indications as NDD.

Live software link

TubePro and Magnifi exchange tube lists and inspection progress through live two-way communication.

Tubesheet model creation

TubePro’s detection tool creates tubesheet models from pictures or drawings and supports large tubesheets.

Dataset comparison

TubePro compares results from different inspection years or techniques on the same tubesheet drawing.

Interactive PDF reporting

TubePro reports can include a 3D equipment model that users can rotate and zoom.

IRIS probe handling

A water-feed slipring enables Probot to be used for IRIS inspections.

Operating conditions & limits

Optimal data recording speed depends on the inspection technique, up to 70”/s.
The stated flexible-probe bend passage capabilities are 3" bend radius (180°) for ECT and 6,5 times tube OD radius bend (180°) for RFT.
DefHi detection and sizing claims are presented for non-ferrous tubes.
For aluminum-finned carbon steel tubes, NFA is presented as a screening tool with IRIS used for proof-up.
IRIS requires water, has a long acquisition time, and cracks remain elusive.
Probot IRIS inspection uses a slipring to feed water to the probe.
The reported Probot productivity figures and DefHi indication counts are specific inspection examples, not general performance guarantees.
