The EMA1900 perfectly fits the requirements of chemical plant inspections: fast multi-point testing, high-altitude/confined pipe racks, operating high-temperature pipelines, testing through rust/coatings without surface grinding, and frequent inspector rotations.
The EMA2800 and EMA3800 serve as ideal complementary models for large-area corrosion mapping and detailed re-examination of high-risk sections.
Why Choose the EMA1900 for Daily Chemical Plant Inspections?
Inspection Pain Points: Dense pipeline networks, crowded elbows/tees, frequent high-altitude work, and many steam/process pipelines operating at high temperatures. Pipeline surfaces are often covered with rust, scale, and anti-corrosion paint.
Daily inspection demands fast readings, lightweight gear, single-handed operation, and instant point logging, without requiring C-scan imaging at every point.
• Integrated Pen-Type Design & Portability: Its compact body effortlessly reaches pipe racks, scaffolding, confined spaces, and the outer radius of pipe elbows. Designed for single-handed operation, it significantly reduces inspector fatigue during high-altitude work.
• Couplant-Free & Grinding-Free: Utilizing Electromagnetic Acoustic Transducer (EMAT) technology, it measures directly through paint, rust, and oxide scale without damaging protective coatings or applying couplant, dramatically improving high-volume screening efficiency.
• In-Service High-Temperature Measurement (Up to 800°C): Enables online inspection of steam and high-temperature process pipelines without shutdown or cooling. Features built-in automatic high-temperature sound velocity compensation.
• Dual Thickness Measurement: Simultaneously measures base metal wall thickness and non-conductive anti-corrosion coating thickness.
• Flexible Interaction & Data Traceability: Features an on-device display for immediate readings. Bluetooth connectivity to an Android tablet enables A-scan waveform visualization, point logging, and report exports, meeting Mechanical Integrity (MI) and compliance requirements.
• Wide Measuring Range: Covers 1–500 mm on carbon steel, satisfying the thickness measurement requirements of most chemical process piping, heat exchangers, and storage tanks.
• High Lift-Off Capability: Supports up to 4 mm lift-off, easily handling thick rust and multi-layer protective coatings.
When to Consider Upgrading to the EMA2800 / EMA3800?
The EMA2800 / EMA3800 multi-functional EMAT thickness gauges feature a large integrated screen with native A/B/C-scan capabilities, up to 6 mm lift-off distance, and combined piezoelectric ultrasonic testing options. Their key strength lies in corrosion mapping, localized Corrosion Under Insulation (CUI) evaluation, and detailed image documentation of critical areas.
• Trade-off: Larger and heavier than pen-type devices, making them less convenient when inspecting hundreds of points across extensive pipe racks.
• Recommended Setup: Use the EMA1900 as the primary workhorse for daily screening, and deploy one EMA2800 or EMA3800 for periodic, detailed scans of critical high-risk lines (e.g., wet H2S environments or erosion-prone elbows).
