Echomac® PA Tube Weld Tester
The new robotic Echomac® PA TW is an operator friendly test system for detecting weld zone defects
in tube and pipe caused by scarfing or welding processes. Electronic scanning ensures that the entire weld zone is covered without the need for mechanical movement or operator adjustment.
ISAFE3 Intrinsically Safe Sensor System
ISAFE3 intrinsically safe sensor system of Vallen Systeme is especially targeted at the petrochemica
l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.
Ultrasonic Testing Immersion Tanks with Unmatched Scanning Features
TecScan’s non-destructive testing Ultrasonic Immersion Tanks & scanners are designed for high pe
rformance and demanding NDT testing applications. Our Scan3D™ line of High Precision Immersion Tanks are specifically designed for automated ultrasonic testing of complex composites parts used in aerospace and industrial applications.
Extended Range Variable Wall® Piping Calibration Blocks for Longseam Inspection
This set of two blocks has been specially designed for situations where ultrasonic examination tak
es place circumferentially or “around the curve” for applications such as inspection of longseam welds in piping and vessels. Jointly designed by PH Tool and Holloway NDT, the blocks feature side-drilled hole reflectors positioned within novel compound-curves, each with multiple thickness steps. The unique design results in a light and compact form factor, with the largest block weighing just over 15 lbs and spanning just 16 ¾”. Coverage is provided for nominal pipe sizes from 6” to 10” in the small block and 12” to a whopping 56” in the large block. The compound OD curves and multiple wall thicknesses actually exceed ASME requirements, providing exceptional signal response and measurement accuracy. Properly managing beam divergence off the ID and stabilizing beam skew due to probe rocking is essential to maintaining a consistent calibration when inspecting lengthwise on curved surfaces.
