New tube ferrite ERNST Blissenbach GmbH has introduced a new ferrite into its line of inside tube scarfing systems: a true impeder giant. The custom-made ferrite MRSH 180 x 200 x 80mm – which additionally includes a MRSH 73 x 200 x 36mm ferrite – guarantees the largest ferrite volume possible for inside tube diameters ranging from 240 to 320mm. It is connected to the hydraulic inside tube scarfer H 179 320 – 10.000 (inside tube diameters ranging from 179 to 320mm). Compared to traditional impeder designs for this diameter range the solution also has the added benefit of easy installation.

impeder efficiency, even in large tube diameters. Just like all the other impeders in the BLISSart product family, the IHZ 240 320 – 82.000 features an impeder guard tube coated with SAFE-COAT, which significantly increases tool life due to its resistance to heat. In addition, water jets are positioned on top of the impeder to immediately flush away any spatter accumulation.

Another advantage is the use of this massive round, fluted ferrite as opposed to small ferrite rods significantly reducing the risk of fracture and guaranteeing consistent performance. The design also makes allowances for optimum cooling of the super ferrite by providing a sufficient number of fluted cooling fins. Comparisons between the BLISSart impeder and designs that are industry standard reveal that in its solution the ferrite is not only found in the upper part of the impeder but the impeder is also filled with ferrite all around. This contributes to a huge increase in

Third generation of self- propelled fusion machine

Series 3. The Automatic version offers control and monitoring over the heat, soak, fuse and cool cycles. The system guides the operator through a step-by- step procedure for fusing pipe. Both the Automated and standard versions have the ability to record fusion parameters with McElroy’s DataLogger ® . McElroy’s complete line of TracStar fusion machines can traverse mud, loose soil, snow and grades up to 30 per cent. The TracStar has the ability to manoeuvre into position under the pipe. All TracStar machines allow for butt fusion of most fittings without special holders and have mitred inserts for fabricating ells in the shop or field.

tolerance ±0.5mm (cut with flying shear). But in recent years there has been also the spread of high strength steels whose superior mechanical properties require – for cutting and levelling – forces and higher powers involving the critical review of the entire mechanics of machines that make up these lines. The importance of the levelling (not to be confused with the straightening Chip McElroy, president of McElroy. “TracStars continues to evolve with customer-provided suggestions having a key role in how designs are evolving. Many of the advancements on the new machine are customer-driven.” The TracStar 500 Series 3 is capable of fusing thermoplastic pipes from 6" IPS to 20" outer diameter in size (180 to 500mm). The fusion carriage can be removed and lowered into a ditch for fusions in tight spaces. Power for the heater is supplied by an on-board generator, while a hydraulic-pump system driven by the engine provides the power for the facer, dual-speed track system and more. Dual hydraulic pipe lifts help to load and unload the pipe into the carriage. Two versions of the TracStar 500 series 3 will be available – a standard model and an Automatic TracStar 500

FIFTEEN years ago, McElroy introduced the first self-contained, self-propelled, all-terrain fusion machine – the TracStar 500. The company is now releasing the third generation of the machine. The new McElroy TracStar 500 Series 3 features major additions over previous models, including an indexer-mounted heater and facer, economy engine throttle setting and hydraulic clamping. With the heater now included as an attached part of the machine, users no longer have to manually place the heater in the carriage during the fusion process. The economy engine setting saves fuel by throttling down when idle. The addition of hydraulic clamping helps reduce operator fatigue and saves time by clamping pipe into jaws of the carriage with the push of a lever. “TracStars revolutionised how people thought of the fusion process,” said

Cut to length THE growing demand for rolled products has increased the demand for speed and precision in cutting: working speed of thickness up to 3mm is 80m/min with an accuracy of ±0.25mm on the length (cut with rotary shear). For thicknesses up to 8mm working speed is 40m/min cutting accuracy ±0.25mm on the length (cut with rotary shear).

that only serves to remove the residual curvature of the winding coil) is generally underestimated. The operation is, however, of fundamental importance for the quality of the sheet. If levelling is not perfect, the plate may seem flat but retain residual stresses in it.
