UNICOR GmbH in Hassfurt, Germany, has developed new corrugators for quick and easy in-line production of protective pipes for PEX, ALU-PEX-pipes and protective pipes for cables. The UC 58/90 (V) as well as the UC 58/120 (V) are UNICOR‘s efficient solutions for pipe-in-pipe production and cable insertion within the pipe diameters from 8 mm i.d. up to 58 mm o.d. The in-line production of pipe-in-pipe or the direct insertion of electric wire into corrugated pipe save one cost-intensive step in the production process by integrating the final fabrication into the production cycle. Thus, additional handling costs can be saved. Combined with only low maintenance UC 58/90 V and UC 58/120 V are the machines guaranteeing for economic success. UNICOR’s pipe-in-pipe technology is also available with the medium-sized corrugators UC 75 and UC 100. More: www.unicor.com.

This year, Nexans is to launch a new machine in the UNIWEMA® (UNIversal WElding MAchine) series which is capable of producing even larger corrugated tubes. Here, single and double-wall corrugated tubes are used in cases requiring a flexible, high-capacity and, if necessary, heat-insulating transport medium or secure sheathing, e.g. as mechanical protection in the implementation of media cables. The new UNIWEMA® U650 produces tubes with external diameters of up to 650 mm and wall thicknesses of up to 3 mm; the length of the corrugated tube is restricted exclusively by the transport capacities. + + + A Nexans UNIWEMA® (UNIversal WElding MAchine, see photo) produces corrugated tubes by forming stainless steel tapes into tubes, welding them longitudinally and, using the corrugating tool, impressing the characteristic corrugated structure.
