What is Long Range Ultrasonic Testing (LRUT)?

Long Range Ultrasonic Testing (LRUT) employs low-frequency sound waves that travel vast distances along pipe walls, detecting hidden internal discontinuities like corrosion, erosion, and cracks. Unlike traditional NDT, LRUT inspects extensive pipelines (up to 350 meters) from single access points, enabling proactive risk identification and safeguarding operational continuity without disruptive excavations. This powerful NDT technique empowers informed decision-making, extending pipeline life, promoting safety, and optimizing maintenance strategies.

Benefits of Long Range Ultrasonic Testing (LRUT)

  1. Inspect long pipe lengths: Covers extensive pipelines (up to 350 meters) from a single access point, minimizing disruption and cost.
  2. Early detection of internal flaws: Identifies potential leaks, ruptures, and structural weaknesses before they compromise safety or operations.
  3. Reduced maintenance costs: Proactive detection minimizes unexpected shutdowns and costly repairs, optimizing maintenance schedules.
  4. Improved regulatory compliance: Ensures adherence to pipeline safety regulations by providing comprehensive assessments of pipe integrity.
  5. Safe and non-destructive: No need for excavation or pipe removal, preserving asset integrity and minimizing downtime.

Applications of Long Range Ultrasonic Testing (LRUT)

  1. Oil and gas pipelines: Inspecting pipelines transporting oil, gas, and other fluids for corrosion, cracking, and manufacturing defects.
  2. Water and wastewater pipelines: Evaluating the integrity of pipelines carrying vital water and wastewater resources.
  3. Offshore pipelines: Assessing the health of critical pipelines in challenging marine environments.
  4. Buried and inaccessible pipelines: Inspecting pipelines hidden beneath ground or within structures without excavation.
  5. Pipeline coatings: Verifying the integrity and effectiveness of applied pipeline coatings.

Long Range Ultrasonic Testing (LRUT) Standard Codes

  1. ASME B31.8 (Gas Transmission and Distribution Piping Systems): Provides comprehensive guidelines for the inspection and maintenance of gas pipelines, including specific requirements for LRUT technology when assessing pipeline integrity.
  2. API 570 (Piping Inspection Code): Offers detailed standards for in-service inspection, rating, repair, and alteration of piping systems across various industries, ensuring LRUT inspections align with best practices and regulatory requirements.
  3. ISO 16809 (Non-destructive testing — Ultrasonic testing — Guided wave testing): Establishes general principles and methodologies for guided wave testing, which encompasses LRUT techniques, ensuring our inspections follow globally recognized quality benchmarks.
