Sonagel W

 

Overview

Sonagel W .jpg

This couplant is designed for use on all types of metallic surface and is especially suited to solving the problems of rough, pitted, uneven surfaces to allow smooth probe movement during testing.

The thixotropic properties of this couplant give excellent wetting and acoustic transmission and do not allow the product to flow all over the test area; and so is very economical to use as you only cover the working area not the whole piece.

Features

Sonagel W incorporates chemicals, which allow very slow drying even at elevated temperatures, whilst being free 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 easily removed with water or solvent wipes.

Sonagel W is available in easy to use 125ml applicator bottles, 250ml bottles, as well as in plastic 1 litre, 5 litre and 25 litre bulk containers (with suitable carrying handles).

*NB: This product will have a flash point of 160°C (PM) when used for long periods at elevated temperatures.

Application Notes

Ultrasonic NDT Corrosion Mapping From Phased Array to FMC-TFM

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

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 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 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 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.
