LRUT Screening for Utility and Process Piping in Thermal and CCPP Power Plants

LRUT Screening for Utility and Process Piping in Thermal and CCPP Power Plants

Introduction LRUT for Power Plant Piping Systems

Thermal and combined cycle power plants operate extensive aboveground piping systems handling steam, feedwater, condensate, fuel gas, cooling water, and auxiliary services. These pipelines are exposed to high temperatures, thermal cycling, moisture accumulation, and environmental corrosion. Maintaining pipeline integrity in power plants is critical for operational reliability, plant safety, and regulatory compliance.

NDT AND PWHT SOLUTIONS PVT LTD delivers advanced Long Range Ultrasonic Testing (LRUT) / Guided Wave Ultrasonic Testing (GWUT) services for power generation facilities worldwide. Our LRUT solutions provide efficient screening of long piping runs from limited access points, enabling early identification of corrosion-prone zones and supporting preventive maintenance planning. We operate globally with certified LRUT specialists and advanced piezoelectric and EMAT guided wave systems.

Integrity Challenges in Power Plants

Power plant piping systems face multiple degradation risks:

➤ Corrosion Under Insulation (CUI)
➤ Thermal fatigue and oxidation
➤ External atmospheric corrosion
➤ Moisture accumulation at low points
➤ Corrosion at supports and hangers
➤ Coating degradation
➤ Dead legs and stagnation zones
➤ High-temperature service conditions
➤ Limited inspection access in congested layouts

Conventional inspection often requires extensive insulation removal and scaffolding. LRUT enables screening of long sections efficiently and safely.

Our LRUT Strategy for Power Plant Piping Networks

🔹 Long-Range Screening of Utility & Process Lines

Efficient evaluation of extended pipe runs from single test locations.

🔹 Corrosion & Wall-Loss Detection

Screening-level identification of suspect metal loss areas for targeted verification.

🔹 CUI Prioritization

Optimized insulation removal planning based on guided wave findings.

🔹 EMAT Guided Wave Capability

Inspection of high-temperature steam lines without traditional coupling limitations.

🔹 Critical Zone Screening

Focused assessment around supports, hangers, low points, and drain areas.

🔹 Shutdown Planning Support

Pre-maintenance screening to reduce unexpected discoveries during plant outages.
