inspection of 5" diameter carbon steel alloy or stainless steel in the Ukraine. This equipment comprised a multi-test system incorporating a 10-channel 5" rotary head Echomac ® FD-4 ultrasonic tester, a MAC 250 encircling coil eddy current tester and a production comparator unit. The use of all three combined technologies has ensured detection of multiple conditions in the tube. The UT can sense long, shallow ID defects specified by API standards. The eddy current detects surface transverse defects and holes, while the production comparator verifies alloy or grade. Marking steel and non-ferrous cylindrical products Couth Butzbach Product Marking GmbH, Germany, are specialists in hard material marking technology. With a range of marking tools, the company enable conventional methods by hand stamps, machine stamps or dies. These tools can be built into presses or unrolling machines in order to work semi-automatically. These tools are produced as standard products or according to customer requirements with consideration of standards including ASME. In addition, a fully automatic controlled dot marking system can be supplied for constantly changing marking of each workpiece with text or a data matrix code. A control unit carries out the marking of numbers, letters, brand names and 2D code. Marking speeds of up to 16 characters per second and a penetration depth up to 0.8mm can be achieved with these dot matrix marking systems. The dot matrix marking system is available as a hand held or table marking unit or as an installation system for integration into the manufacturing process. Couth Butzbach also produces special marking units to mark products with temperatures up to 1200°C, particularly used for the steel plant industry.

Flux leakage testers find growing demand in expanding API tube market

Accelerated technical development in countries such as Kazakhstan, Russia and the Ukraine has resulted in a strong demand for flux leakage test systems for large diameter steel and cast iron tube, typically used for oil and water delivery systems. Magnetic Analysis Corp, USA, has recently delivered a 16" capacity flux leakage test system for inspecting 14" diameter steel tube. It features 24 channels of multiplexed electronics derived from 24 separate test probes that rotate around the tube during the test.

The short, sensitive probes can detect longitudinal notches as short as 0.5" (12.7mm) and through holes as small as 0.032" (0.8mm). Thresholds for ID and OD can be set independently and each channel is viewed separately on screen with zoom-in capability. These combined features result in ease of setup and data interpretation by the operator. The robust 16" Rotoflux mechanics include a built-in calibration station and AC variable speed belt drives for the pinches. There is also a slide and elevating platform on rails with a crank powered chain drive for the slide and a motor driven vertical elevator.

The slide has 3 preset stop positions – testing online, calibrating offline (for setup and checking standards), and totally offline for maintenance tasks. The new calibration station, parallel to the test line, and with its own pinch stands and conveyor, is integrated into the welded structural steel frame of the full test system. The square tube steel frames provide the extra strength and rigidity required to handle

The test screen display, modeled on MAC’s highly successful EchoHunter ® FD-4 software, simultaneously shows 24 channels of OD and 24 channels of ID signals. A strip chart display shows the maximum ID and OD signals from any of the 24 channels during a selectable time period, within milliseconds.
