What is Phased Array Ultrasonic Testing (PAUT)?

Phased Array Ultrasonic Testing (PAUT) employs an advanced probe with multiple piezoelectric elements to electronically control the direction and focus of sound waves within materials. Imagine an array of microscopic flashlights shining sound energy deep into structures, revealing internal cracks, voids, and other discontinuities with exceptional precision. Unlike traditional UT, PAUT can navigate complex geometries and hidden areas, providing unparalleled insights into the hidden depths of your critical assets. This powerful NDT technique guarantees thorough inspections and reliable data, empowering informed decision-making for asset integrity and operational continuity.

Benefits of Phased Array Ultrasonic Testing (PAUT)

  1. Superior defect detection: Identifies cracks, voids, and other anomalies with exceptional accuracy and detail, even in challenging geometries.
  2. Faster inspections: Covers large areas quickly and efficiently compared to traditional UT methods.
  3. Reduced inspection costs: Minimizes the need for multiple UT techniques, streamlining the inspection process.
  4. Improved weld integrity assessment: Provides in-depth analysis of weld quality, maximizing weld reliability and safety.
  5. Comprehensive data visualization: 3D visualizations offer intuitive understanding of internal flaws and their location.

Applications of Phased Array Ultrasonic Testing (PAUT)

  1. Pressure vessel inspection: Ensuring the integrity of critical vessels in power plants and refineries.
  2. Pipeline inspection: Detecting internal corrosion and cracking in pipelines transporting oil, gas, and other fluids.
  3. Weld inspection: Assessing the quality and integrity of welds in various structures, including bridges, offshore platforms, and aircraft components.
  4. Casting and forging inspection: Identifying internal defects in critical cast and forged components.
  5. Corrosion mapping: Detecting and mapping internal corrosion in various materials and structures.

Phased Array Ultrasonic Testing (PAUT) Standard Codes

  1. ASME Section V, Article 4: Provides comprehensive guidelines for ultrasonic examination in pressure vessels and boilers, outlining specific procedures and acceptance criteria for PAUT applications.
  2. ISO 13588: Establishes general principles for ultrasonic testing, ensuring our PAUT inspections follow best practices and standardized methodologies.
  3. ASTM E2491: Guides the evaluation of performance characteristics for PAUT instruments and systems, guaranteeing the accuracy and reliability of the data we acquire.
  4. API 579-1/ASME FFS-1: Offers vital guidance on Fitness-for-Service assessments, enabling us to utilize PAUT to evaluate potential threats like Hydrogen Induced Cracking (HIC) and inform informed repair or replacement decisions.
  5. API 5L: Specifies requirements for line pipe inspections, ensuring safe and reliable pipeline integrity assessments through PAUT technology.
