PAUT And TOFD Inspection

Phased Array Ultrasonic Testing (PAUT) is an Advanced NDT technique that employs a set of ultrasonic testing (UT) probes comprised of small conventional transducer elements. Each transducer can be pulsed individually with computer-calculated phasing

The demands for reliable in-service inspection are on the rise without going for shutdown to cut the huge costs involved. To apply fitness-for-service calculation the inspectors require the remaining wall thickness and defect characterization to study criticality and the remaining life estimation of the vessel. Modern fracture mechanics engineering requires the classification of defects either surface or subsurface, length as well as the height of the defects to analyze their criticality for acceptance or rejection criteria.

Normally conventional NDT techniques like UTG and radiographic testing are utilized during shutdown but there are many disadvantages associated with such methods.

LIMITATIONS OF RADIOGRAPHY

With the new advanced technologies like Phased array ultrasonic testing (PAUT) and time of flight diffraction (TOFD) With added accessories even high temperature inspection up to 350oC is nare feasible. The results obtained are highly reliable and repeatable. Accuracy in terms of defect length, and height sizing makes fracture mechanics analysis possible. With data encoding, digitization and storage of the data is possible for post-analysis similar to radiographs.

  • Mainly the ionizing radiations are hazardous and require evacuation of the area increasing shutdown downtime as other activities are not possible.
  • Access to both sides of the vessel is required for source and film placement, increasing the overall cost for the removal of insulation from the outside and refractories from the inside.
  • Scaffolding is needed for access to all areas for placement of films, sources, etc.
  • The probability of detection of planar defects like Lack of fusion, and cracks is poor unless the defect planes are oriented parallel to the radiation beam and
  • In RT estimation of the actual defect height or depth is not possible. This adversely affects the repair plans.
  • Heavy wall pressure vessel above 60mm thickness involves the use of Cobalt 60, thus compounding the safety issues and reducing the detection capability.

PHASED ARRAY ULTRASONIC TESTING

Phased Array (PA) transducers can be thought of as multiple small conventional transducer elements housed in a single unit. Each transducer can be pulsed individually and by varying time between pulses from the elements such that constructive interference of the individual waves can occur, the desired angle and focus is achieved.

Remote Field Electromagnetic Inspection

The Remote Field Eddy Current (RFET) is a variation of the Eddy Current send-receive probe technique. RFET technique allows the use of the differential- and absolute mode This technique is capable of the detection of localized defects with the differential mode and gradual defects with the absolute mode The detector coils are separated by a distance equivalent to two or three times the tube diameter. The receiving coils sense the flux lines that cross the tube wall twice Remote field has an equal sensitivity to internal and external indications while the phase shift is directly proportional to wall loss.

Advantages of Remote Field Electromagnetic Testing

  • Up to 500 tubes of 6 meters in length can be inspected in 12 hrs.
  • Can inspect ferromagnetic tubes up to 3.5 inches in diameter with 0.125 inches wall thickness.
  • Inspection speed (up to approx. 40 feet per minute).
  • Can detect large-area discontinuities such as steam erosion and baffle wear.
  • Amplitude changes in the signals sensed are not speed-sensitive.
  • Flexible probes can be used to inspect and travel through U-bend areas.
  • Permanent records can be obtained on test results.

Limitations of Remote Field Electromagnetic Testing

  • Limitation to distinguishing ID from OD defects.
  • Evaluation of small flaws such as pits can be difficult.
  • Instrumentation and test probes can be very expensive.
  • Tubes must be cleaned.
  • Inaccuracy in test results could occur if a discontinuity encountered differs in geometry from calibration discontinuities.
Magnetic Flux Leakage Inspection (MFL)

Magnetic Flux Leakage (MFL) testing is a widely used, Non-Destructive Testing (NDT) method for the detection of corrosion and pitting in steel structures. MFL is often used for pipeline inspection, storage tank floor inspection & Tube inspection

THE PRINCIPLE

MFL probes incorporate a magnetic detector placed between the poles of the magnet where it can detect the leakage field. During inspection, a magnetic circuit of sorts forms between the part and the probe. The magnetic field induced in the part saturates it until it can no longer hold any more flux. The flux overflows and leaks out of the pipe wall and strategically placed sensors can accurately measure the three-dimensional vector of the leakage field. Because magnetic flux leakage is a vector and a sensor can only measure one direction, any given probe must have three sensors to accurately measure the axial, radial, and circumferential components of an MFL signal.

Pipes can MFL Pipeline Inspection System for Corrosion Detection

MFL pipe scan system is used for rapid screening and detection of random internal corrosion in pipe and small diameter vessels, It has coverage of all diameters from 48mm to 2.4 meters with a limited number of scanning heads MFL Pipe scan is an easy-to-use, cost-effective, and portable. Magnetic flux leakage inspection is not affected by product flowing through the pipe so surveys can be carried out both online and off-line and at surface temperatures up to 90°C. The use of Pipe Scan, with its high probability of detection to locate the corrosion, coupled with ultrasonic prove up, provides a cost-effective accurate system for the determination of plant integrity.

3D MFL Tank Floor Inspection

Aries employs a 3D MFL floor scan capable of independent identification and recording of top and bottom defects with a single scan. A portable handy scan is also utilized for annular plates and areas with restricted accessibility.

Magnetic Flux Leakage Tube Inspection

Magnetic flux leakage (MFL) is a tube-testing technique used for the inspection of ferromagnetic tubes. The technique is primarily designed for fast screening if small diameter pitting is expected. Magnetic Flux Leakage is very susceptible to sharp-type flaws such as pits and grooves. Pits can be detected both inside and externally. MFL cab detects progressive wall-thinning and distinguishes between internal and external defects depending on probe design.

Aries has a multi-functional system for tube inspection to detect wall-thinning

  • MFT - Magnetic Flux Leakage Testing
  • ECT - Eddy Current Testing
  • RFT - Remote Field Testing
  • IRIS - Internal Rotary Inspection System
