Sonagel LTHT

 

Overview

Sonagel LTHT .jpg

This product is designed for use on all types of metallic surface and allows smooth probe movement during testing, at elevated temperatures. This gives good probe contact and acoustic transmission and prevents flow over the test area. It is very economical to use as you only cover the working area and not the whole piece.

Application Notes

Aerospace Structural Control

Aerospace Structural Control

Improving resistance properties in composite is all about improving stress and strain resistance such as ultimate tensile strength.

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.
