Advances in ultrasonic measurement for Nitinol tubing

Haventrak ™ flying shear for cutting expertise

Haven Manufacturing, USA, has introduced an exciting addition to its tube cutting product line – the Haventrak ™ flying shear. Haventrak utilizes the speed and precision of the company’s ‘dual- blade shear’ cut-off head. The system takes advantage of the ‘Utrak’ length control system to deliver accurate, high quality, dimple free cuts on-the-fly. This innovative approach will provide improved production rates with increased accuracy at up to 250 FPM.

LaserLinc, a producer of precision measurement systems, has developed new testing solutions for its ultrasonic line. The company has applied ultrasonic technology to measure medical-grade Nitinol tubing, and claims that its application is the only practical, non-destructive and in-process method available. Using the UltraGauge+ ultrasonic system and a laser scanning micrometer, LaserLinc can provide the inside diameter, wall thickness, and outside diameter of the material. Nitinol (nickel titanium/NiTi) is a shape memory alloy used in, among other things, medical devices. Because of its unique crystalline structure, Nitinol has been difficult to measure accurately with ultrasonics, and because of its high cost, accurate measurement is a priority for manufacturers. LaserLinc has also created UltraLock, a wave-analysis procedure designed to simplify the time-consuming and difficult process of setting up ultrasonic measure- ment systems. With the UltraLock setup procedure, the user can reduce complexity of ultrasonic measurement to one step, without reducing control over the system. The user can also quickly and automatically set software parameters to ensure accurate and reliable measurement, even if the product size changes during a production run. In addition, the system can be configured to measure all layers of multi- layer products simultaneously. UltraLock, a feature of LaserLinc’s Total Vu software, is designed specifically to work with the company’s UltraGauge+ ultrasonic measurement system. Total Vu gives users access to powerful computational, data processing, and data collection tools. The software makes it possible to use in-process tolerance checking, trending, SPC, feedback control, data logging, recipes and other configurable features.

Haven Manufacturing has gained worldwide acceptance by producing high quality cuts on a variety of tubular shapes and materials utilizing the dual-blade shearing method. Universal Controls Group, USA, developed the Utrak length control system blending hi-tech electronics and simple mechanics to provide an accurate yet rugged solution to length control needs. Haventrak ™ integrates two of the most recognized names and know-how in the tube cutting industry to provide improved quality and accuracy.

Simultaneous conditioning of tube ends – inside and out

After making a weld preparation, most tube and pipe has to be polished in order to avoid pollution of the weld. Th Wortelboer BV, the Netherlands, has developed a revolutionary solution to polish the inside and outside at the same time in one cycle.

The compact TPP 5090 is a safe machine for easy cleaning of welding preparations. It is possible to quickly and safely prepare tube, pipe and plate edges for welding.

The two polishing wheels of the TPP 5090 can be adjusted according to the thickness of the material. The inevitable wear of the wheels, which decreases the wheel diameter, can be corrected. The new innovative TPP 5090 conditioning machine is a registered design.
