Hydrogen Blister Progression FMC/TFM Assessment

TFM (top) vs. PA (bottom) image

Hydrogen blistering usually occurs in systems where oil & gas contain large amounts of hydrogen sulphide. At high temperatures, when hydrogen atoms diffuse into the steel, hydrogen molecules form an internal defect or inclusion that usually migrate to become a small delamination. Over time, this can form voids or blisters which lower the equipment MAWP (maximum allowable working pressure) and may lead to equipment failure.

Ultrasonic NDT Corrosion Mapping From Phased Array to FMC-TFM

Corrosion inspections are used to evaluate the remaining wall thickness or the presence of mid-wall anomalies in pipeworks, pressure vessels, and other metallic structures. These inspections have always been at the heart of many problematic situations for production, maintenance and integrity considerations because of the safety and cost issues. Such material degradation can cause many problems to the industrial and civil infrastructures.

FMC/TFM Technique for Defect Characterisation

Defect characterisation has always been a challenge for ultrasonic inspection techniques. Phased array has greatly enhanced the interpretation compared to conventional UT. However, some defects are still easily misinterpreted such as cracks with slag or lack of penetration depending on the geometry of the root.

Austenitic Stainless Steel Solution DAAH - Dual Linear Array Probe


Austenitic stainless steel is well known for its high mechanical properties and corrosion resistance. This material is often used in the oil and gas, and nuclear industries where ultrasonic inspection techniques represent an important portion of the quality control process. However, these alloys often are very attenuating and the sound propagation in this material is anisotropic.

Hydrogen Blistering Inspection with Phased Array


Hydrogen blistering usually occurs in ‘sour’ systems where oil or gas contain large amounts of hydrogen sulphide. At high temperature when hydrogen atoms diffuse into the steel, hydrogen molecules then form an internal defects or inclusions that usually migrate to become a small delamination. Over time, this can form voids or ‘blisters’ which may eventually generate enough pressure to rupture the metal.

Ultrasonic Testing of Composite using Phased Array


Nowadays, the composite material is being used widely, namely because of its unique characteristics. QA of parts and laminates made of the composite is a challenge. Nevertheless, using UT techniques to perform NDT inspection of such parts provides equally reliable and repeatable results for both in-line and maintenance examination.

Spotweld Probe


Spotwelds on automotive components and other structures require inspection for a number of possible failure modes. Adhesive (stick) welds, burnt welds and unfused welds are several types of failure modes.

Long Seam weld Inspection with Phased Array

Gary Lowton at Titan.JPG

​Phased Array inspection of curved parts brings some real technical challenges. Evaluation of seam welds on small diameter and heavy wall pipes is difficult to accomplish using actual tools that, most of the time, are based
on a flat surface model. This often leads to erroneous and imprecise flaw location and sizes.
