Technology Update

Eddy current flaw detectors

in fields such as aerospace, and weld and surface flaw inspectors in a wide range of non-ferrous application environments.

Olympus NDT, USA, has introduced Nortec 500, a new series of portable eddy current flaw detectors. Available in three full- featured, lightweight configurations, the flaw detectors include a 6.5" diagonal full VGA colour LCD screen for increased resolution. Internal balance coils allow the use of absolute probes without the need for external balance coil adapters, and a

built-in preamplifier adds extra gain, when required. VGA output allows for optional ‘heads up display’ for hands-free operation, while the optional remote-null adapter adds convenience and assures safety. The Nortec 500 includes PowerLink™ for automatic probe recognition and program set-up, and a USB interface provides rapid information transfer. The Nortec 500 delivers basic, single frequency eddy current inspection including external outputs. The Nortec 500S adds digital conductivity, coating thickness measurement, and rotating scanner use. The Nortec 500D matches the 500S and includes dual frequency capabilities. The new detectors are packaged in foreign object debris-free cases, and feature a single Li-Ion battery suitable for demanding environments and intense applications.

The Nortec 500 series is suited to the requirements of manufacturers

Continuous shot-blasting installation for external tube surfaces

Carlo Banfi, Italy, manufacture the ISTR series installation for external tube and pipe shot-blasting for a maximum diameter of 20" (500mm). These installations are equipped with throwing wheels arranged on the upper part of the blasting room.

A special conveyor system controls the piece feeding, as well as rotation on its own axis, so that the whole external surface is exposed to the blasting action. For larger diameters (up to 60") the piece movement is achieved by sets of wheels with inclined axis and fixed angles compared to the tube axis. For medium-large diameters (20" ÷ 80") the throwing wheels are placed below the piece level, so that the distance between the throwing wheel axis and the surface to be processed remains constant according to the tube diameter. The inlet and outlet pre-rooms are equipped with rubber protections that prevent leaks of shot-grit to the outside.

› Karl Theis produces pipes for heating and cooling elements

The company produces and processes half pipes for use as heating or cooling elements for large tanks. The company also specialises in the production of U-pipes. which are one of the main components of power plant construction and heat exchanger construction. Also in the Karl Theis range are coiled pipes, tube bends and non-standard designs. With a production area covering more than 4,000m 2 , the company shapes and welds tubes of almost any ferritic and austenitic material, with dimensions from 6mm to 323.9mm.
