CASE STUDY | In-service stack inspection by UAV
Significant corrosion can occur in stacks and flares due to the presence of acidic compounds in the gases, in the presence of moisture and at elevated temperatures.
A refinery operator sought to inspect their stacks, onstream at high-temperatures using aerial drone platform with a HotSense UT payload to determine fitness for service.
Read our latest case study that highlights why on-stream inspection requires robust transducers with high sensitivity and temperature resilience , and which can reliably make high-temperature wall thickness measurements to prevent the need for shutdown and maintain productivity while reducing costs.
Application Note – High-Temperature Weld Root Corrosion Inspection
Ionix high-temperature TOFD transducers, with integrated wedges, are suitable for weld inspections at continuous elevated temperatures up to 350 °C. Here, the transducers with integrated wedges are mounted on to a modified EddyFi Lyncs scanner for high-temperature encoding, with high-temperature couplant, connected to
commercially available Mantis UT set, and a carbon steel pipe weld inspected at 200 °C for weld root corrosion.
Application Note – High-Temperature TOFD Inspection of Carbon Steel Weld
Ultrasonic time-of-flight diffraction (TOFD) is a popular method widely used in petrochemical, energy and other industries for the in-service detection and characterisation of welds defects such as root corrosion, porosity, inclusions, and cracks. This latest application note explores Time-of-flight diffraction on carbon steel welded plate up to 240 °C.
Ionix visits GHANST and delivers a High Temperature Masterclass
Ionix was welcomed back to Houston to connect with new and existing friends as well as conduct our high temperature masterclass aimed at giving current Ultrasonic NDT Technicians the training and confidence required to perform high temperature measurements using Ionix true high temperature transducers based on the award winning HotSense™ platform.
High-temperature TOFD trial
A demonstration of the Ionix high-temperature TOFD transducers, with integrated wedges, for their suitability for weld inspection at elevated temperatures up to 240 °C is shown here. The wedges are mounted on to a modified EddyFi Lyncs scanner for high-temperature
encoding, with high-temperature couplant, connected to commercially available UT sets from EddyFi and
Olympus.
High-temperature TOFD inspection of carbon steel weld
Ionix high-temperature TOFD transducers, with integrated wedges, are suitable for weld inspection at elevated temperatures up to 350 °C. Here, the transducers with integrated wedges are mounted on to a modified EddyFi Lyncs scanner for high-temperature encoding, with high-temperature couplant, connected to commercially
available Mantis UT set, and a carbon steel plate inspected at 240 °C for lack of side wall fusion and notches in the weld.
High Temperature Weld Root Corrosion Inspection
Ultrasonic time-of-flight diffraction (TOFD) is a popular method widely used in petrochemical, energy and other industries for the in-service detection and characterisation of welds defects such as root corrosion, porosity, inclusions, and cracks. However, with increasing demand for on-stream measurements, conventional TOFD is limited due to the temperature at which these probes can operate, often causing failure of the transducer, or causing noise in the wedges to mask the ultrasound signal.
High temperature weld root corrosion inspection with HotSense™ TOFD
This latest blog explores Ionix high-temperature TOFD transducers, with integrated wedges. Suitable for weld inspections at continuous elevated temperatures up to 350 °C enabling on-stream inspection of critical, hot, assets.
