Magnetic Analysis Corp NDT test instruments and systems for inspecting wire, bar, tube and pipe will be featured at the wire India stand of Magnetic Analysis Corp (MAC) and Inmar Engineering Corp – MAC’s agent in India. Highlights will be the Minimac® eddy current tester and information on MAC’s latest Echomac® phased array ultrasonic systems for testing ERW welded tube. The Minimac 50/55 for detecting short surface and some subsurface defects at speeds up to 4,000 fpm will be demon- strated using a linear rail eddy current coil holder while testing ½" diameter stainless steel tube. This eddy current instrument is also often used for inspecting welding wire, including flux core wire where it can detect missing flux as well as flaws in the wire itself. It can also find weld-line faults in tube and check continuity in single and multi-conductor insulated wire and cable. Using an MID option, the Minimac can

detect magnetic inclusions in non magnetic product. MAC’s MultiMac® eight-channel eddy current instrument is used to detect surface defects and laps in cold drawn wire and high-speed operations. Information will be available on MAC’s Echomac PA TW phased array UT robot system, installed recently at a US tube mill. This new system is able to measure the tube profile and monitor the scarfing trim tool operation in the heat affected zone, often within 40 feet of the welder, at temperatures up to 122°C (252°F). This upstream location in the weld line gives the operator instant feedback when the scarfing tool is bad or broken, allowing immediate adjustment of the welding operation and preventing scrap.

and will stop when the upper sensor is covered by material. As the main raw material is also controlled by a dosing station, the material mixture will always be in the correct ratio. Whether the extruder is being operated at full production speed or at very low rpm has no influence on the quality of the material mixture.

Established in 1971, the company has pioneered the technology of XLPE silane crosslinkable polyethylene compounds, and has been offering HFFR compounds for cable sheathing, wire insulation, pipe and fit ting applications since 1982. In 2017, Padanaplast became a member of Finpro ject, a major Italian business in crosslinka ble polyolefin compounding, extrusion and moulding. Finproject SpA www.finproject.com Padanaplast Srl www.padanaplast.com aerospace installations, will also be available at the stand. The full-body test equipment provides 100 per cent coverage at high throughput rates on product ranging from 5 to 25mm diameter. The 630mm overall length of the rotary allows for ease of installation when upgrading existing inspection lines. Information on MAC’s full range of eddy current, ultrasonic and flux leakage test systems for inspecting wire, bar and tube will be available at the stand. Magnetic Analysis Corp www.mac-ndt.com TBA

Woywod Kunststoffmaschinen Extrusion equipment for the production of small diameter cables and fibre optics is generally small, and the output of these extruders is also relatively small. Consequently, the required amount of colourant might be difficult to handle. Many manufacturers have changed to volumetric mixing stations, which work independently of the consumption of the extruder. A mixing station system has a central neckpiece with two sensors. When the lower sensor is free of material the system will start,

fers a high chemical resistance to fluids such as mineral oils, fuels, hydraulic oils, drilling fluids and other chemicals, where good retention of mechanical properties and low swelling are essential. The manufacturer says that CogegumGFR 1907 is suitable for on- and off-shore ca bles, chemical industry cables and wind mill cables. It also shows good flexibility, resistance to hot pressure up to 140°C, and compact char forming behaviour in case of fire. Padanaplast, based at Roccabianca near Parma in Italy, operates 14 production lines certified to EN ISO 9001, ISO EN

Leveraging its core technologies, the company is able to serve those sectors that are more demanding in terms of high performance, technological know-how, competitiveness and safety. The new grade Cogegum® GFR 1907 of fers a solution where high chemical resis- tance and self-extinguishing performance are required.
