Introduction – Addressing Core Industry Needs and Solutions
Asset integrity inspectors and maintenance engineers face a critical challenge: detecting corrosion and wall loss in pipelines, storage tanks, and offshore platforms without removing insulation, coatings, or marine growth. Conventional ultrasonic testing (UT) requires direct probe contact—stripping insulation (days of labor, costly), removing coatings (damages corrosion protection), or cleaning marine growth (offshore logistics nightmare). Pulsed Eddy Current (PEC) devices are non-destructive testing (NDT) instruments that use pulsed electromagnetic fields to detect flaws, measure thickness, and assess corrosion in conductive materials without requiring direct contact or surface preparation. Unlike conventional eddy current methods that rely on continuous sinusoidal excitation at a fixed frequency, PEC devices send short electromagnetic pulses through a probe coil; the transient response induced in the material is then analyzed to reveal information about hidden defects, wall loss, or coating thickness. PEC is particularly effective for inspecting structures covered by insulation, coatings, or marine growth—such as pipelines, storage tanks, and offshore platforms—because it can penetrate non-conductive layers and provide reliable data without stripping or cleaning the surface. This makes PEC devices valuable tools in industries like oil & gas, power generation, aerospace, and marine maintenance.

1. Core Market Drivers and Technical Advantages
The global PEC devices market is projected to grow at 4.8% CAGR to US$129M by 2032, driven by aging infrastructure inspection (pipelines, storage tanks), cost reduction (eliminating insulation removal), and safety compliance (API 653, ASME, NACE).
Recent data (Q4 2024–Q1 2026):
- Key advantage: PEC penetrates up to 100mm of insulation or non-conductive coating, measures remaining wall thickness with ±5-10% accuracy.
- Time savings: conventional UT requires stripping/reinstalling insulation (2-3 days per inspection point); PEC requires 0 insulation removal – 2-3 hours total.
- Typical applications: corrosion under insulation (CUI), tank bottom corrosion, pipeline wall loss, offshore riser inspection.
2. Segmentation: Form Factor and Application Verticals
- Portable Handheld: Largest segment (70% market share). Battery-operated, single-person operation. For spot inspections, small pipes, tank shells, offshore platforms, above-ground storage tanks. Weight: 2-5 kg. Range: 0-50mm steel thickness. Price: $30,000-70,000. Vendors: Eddyfi Technologies (PECA), ETher NDE (ePEC), Sixpec, Henan Dellon, HUATEC.
- Vehicle/Rig-mounted: 30% share. Larger systems for scanning large areas (tank floors, pipelines, vessel shells). Automated scanning (motorized), higher power (deeper penetration, 0-100mm+). Price: $80,000-200,000.
- By Application:
- Oil and Gas: Largest segment (50% of revenue). Pipelines (onshore/offshore), storage tanks (API 653 inspections), pressure vessels, risers, flow lines. CUI (corrosion under insulation) primary driver.
- Marine: 15% share. Ship hulls, ballast tanks, offshore platforms, subsea structures. No surface preparation (marine growth, coatings) – PEC unique advantage.
- Chemicals: 10% share. Chemical storage tanks, reactors, piping under insulation or protective coatings.
- Others: 25% (power generation – boiler tubes, cooling water piping; aerospace; structural steel).
3. Industry Vertical Differentiation: PEC vs. Conventional NDT Methods
PEC occupies a unique niche for inspecting through insulation/coatings:
| Parameter | PEC | Ultrasonic (UT) | Conventional Eddy Current (EC) | Radiography (RT) |
|---|---|---|---|---|
| Surface preparation required | None (through insulation/coating) | Yes (direct probe contact – remove insulation, grind coating) | Yes (remove coating) | No (but safety zone required) |
| Penetration through insulation | Yes (up to 100mm) | No | No | Yes (but insulation may affect) |
| Accuracy | ±5-10% of thickness | ±1-2% | ±5-10% | ±2-5% |
| Inspection speed | Moderate (2-5 sec/point) | Fast (<1 sec/point after prep) | Fast | Slow (film processing) |
| Safety hazard | None (electromagnetic) | None | None | Radiation (safety zone, licensing) |
| Operator skill | Moderate (PEC signal interpretation) | High (UT waveform analysis) | Moderate | High (film interpretation) |
| Equipment cost | $30,000-200,000 | $5,000-50,000 | $10,000-50,000 | $50,000-200,000 |
| Best for | CUI, insulated pipelines, tank floors, marine | Bare metal, high accuracy | Surface cracks, conductive coatings | Weld inspection, volumetric defects |
Unlike UT (requires direct contact – stripping insulation), PEC penetrates insulation and coatings – saving days of labor and avoiding re-insulation costs. Primary limitation: lower accuracy (±5-10% vs UT ±1-2%) – suitable for corrosion screening, not final sizing.

5. Exclusive Industry Insight: PEC vs. UT TCO and the Insulation Removal Cost Avoidance
Our analysis reveals a critical economic advantage: PEC’s ability to inspect through insulation avoids $5,000-20,000 per inspection point in insulation removal/reinstatement costs, making it highly cost-effective for CUI screening despite higher equipment cost.
Proprietary TCO analysis (100 inspection points, refinery piping, 5 years) :
| Cost Component | PEC (Eddyfi Lyft) | UT (Conventional) | Difference |
|---|---|---|---|
| Equipment capital | $65,000 | $15,000 (UT gauge) | PEC +$50,000 |
| Training/certification | $10,000 (PEC Level II) | $8,000 (UT Level II) | PEC +$2,000 |
| Total initial | $75,000 | $23,000 | PEC +$52,000 |
| Insulation removal/reinstatement (100 points @ $200/point – labor + materials) | $0 (no removal) | $20,000 | PEC -$20,000 |
| Scaffolding/access (100 points @ $100/point) | $0 (PEC scans from outside) | $10,000 (UT requires access to pipe surface) | PEC -$10,000 |
| Inspection labor (100 points @ 0.5 hours/point vs 1 hour/point) | $2,500 (@$50/hr) | $5,000 | PEC -$2,500 |
| Data analysis/reporting | $5,000 (software included) | $3,000 | PEC +$2,000 |
| Total operating (per inspection campaign) | $7,500 | $38,000 | PEC -$30,500 |
| 5-year (4 campaigns) | $30,000 | $152,000 | PEC -$122,000 |
| 5-year TCO | $105,000 | $175,000 | PEC saves $70,000 (40%) |
Key insight: PEC TCO lower despite higher capital. Payback period: 1-2 inspection campaigns (50-100 points). For large-scale CUI screening (500+ points/year), PEC savings exceed $200,000 annually.
Decision matrix – Choose PEC when :
| Factor | PEC Recommended | UT Sufficient |
|---|---|---|
| Insulation/coating present | Yes (CUI screening) | No (bare metal) |
| Inspection points | >50 points/year | <20 points/year |
| Access difficulty | High (elevated pipes, offshore) | Low (ground-level, bare) |
| Accuracy requirement | Screening (±10%) | Final sizing (±2%) |
| Budget for equipment | >$50,000 (capital available) | <$20,000 |
| Typical applications | Refineries, offshore, chemical plants, pipelines | Manufacturing, in-plant bare metal |
