Shaft Inspection Using Phased-Array Compared to Other Techniques


27th November 2019

Technical Paper

The main purpose of this article is to suggest a new multi-orientated Phased Array (PA) inspection, which could reduce the cleaning and disassembly of shaft assembly in general.

The main idea is to replace the conventional surface technique inspection by an encoded circumferential PA inspection using the Curved Surface Correction (PA CSC) of the Veo+. This inspection, combined with a PA inspection at the extremity of a shaft would cover all the possible flaw orientation and hopefully increase the probability of detection, the interpretation capability and productivity.

Phased Array Techniques and Defect Evaluation for Composites

8th November 2019

Composite materials are well known for their stiffness, corrosion resistance and low density and they come in all different geometries. Theses composite complex shapes along with their anisotropy, makes UT inspection more challenging than inspections for conventional materials like steel.

This scientific paper will address general issues of composites relating to geometry, attenuation and assessment methods.

The main types of T-joint welds are inspected with conventional UT, where common defects are generally cracks and lack of fusion. Having a better understanding of the defects can certainly help the technicians become more alert, especially when considering the main problematic areas.

Defect characterisation has always been a challenge for ultrasonic inspection techniques.

Hydrogen Blister Progression FMC/TFM Assessment

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.
