Solution: Corrosion Mapping – Phased Array (PA)
Corrosion Mapping
Phased array testing helps make corrosion inspection fast and efficient. Our operators are trained and qualified to collect higher resolution data with fully encoded C-scan imaging. These images give a real top view color print of the internal surface.
With TRL Phased Array probes and a dedicated 2-axisscanner TÜV AUSTRIA Belgium offers efficient inspection options for detecting loss of wall thickness due to corrosion, abrasion, and erosion. This technique can also detect mid-wall damage, such as hydrogen-induced blistering or manufacturing-induced laminations, and easily differentiate these anomalies from loss of wall thickness.
Phased array ultrasonics (PA) is an advanced method of ultrasonic testing that has applications in medical imaging and industrial nondestructive testing. The Phased Array technique used for weld volume examination is fully code compliant (ISO and ASME) and can be used for welds starting thickness 6mm up to 125mm. This technique requires access from one side of the weld and can be used for vessels or piping (from 1”) in carbon or stainless steel.
With dedicated scanners and probes TÜV AUSTRIA Belgium offers rapid weld inspection that can replace radiography during day-time with only one operator. Our trained and highly experienced operators will compare the dimensions of detected flaws to ISO or ASME acceptance criteria and the report is generated the same day on site. Dangerous irradiation (RT) is not present. No need to develop films or travel to the dark room office.
Did you know that TÜV AUSTRIA Belgium also provides non-destructive testing (NDT) services for plastics, in addition to metals?
Plastics such as HDPE and Teflon linings are increasingly important construction materials in the chemical industry. Just like metallic components, these materials are subject to welding quality, integrity requirements, and potential in-service degradation.
Our expertise in NDT is directly applicable to plastics. Ultrasonic testing (UT) techniques are particularly well-suited for weld inspection and crack detection in HDPE piping and other polymer-based components. TÜV AUSTRIA Belgium has already executed several successful cases in this field, demonstrating the potential of these methods to ensure long-term reliability and safety.
Throughout the lifecycle of an installation, TÜV AUSTRIA Belgium supports asset owners with reliable solutions. While damage analysis of plastics is typically conducted in collaboration with external partners, our in-house NDT services provide a strong foundation for quality assurance and compliance.
