This product is designed for use on all types of metallic surface and is especially suited to solving the problems of rough, pitted, uneven surfaces allowing smooth probe movement during testing.
The thixotropic properties of this couplant give excellent wetting and acoustic transmission and do not allow the produce to flow all over the test area. This makes it very economical to use as you only cover the working area and not the whole piece and is especially suitable for vertical and overhead surfaces.

Sonagel O incorporates chemicals, which allow very slow drying even at elevated temperatures, whilst being free of VOC's and other hazardous materials. However, it does contain a special tracer dye to enable areas to be checked for coverage but the couplant is still very easily removed with gentle water washing or solvent wipes. Sonagel O is available in easy to use 125 ml applicator bottles as well as in plastic 1 litre and 25 litre bulk containers (both with suitable carrying handles).
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.
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.
Corrosion Mapping from PA to 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.
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.
