High pipe productivity at SRM mill in Turkey BORUSAN Mannesmann has reported high productivity on its new stretch reducing pipe mill with EFD Induction 750kW tube welder.

but during the factory acceptance test visit at the EFD Induction headquarters in Norway it was decided to upgrade the welder to 750kW. This modification was easily carried out by adding an additional inverter module and carrying out some simple tuning. Since installation, the Weldac has worked flawlessly and has efficiently delivered power for all tube thickness and material combinations. The performance of the welder has enabled Borusan Mannesmann to produce very high wall thicknesses on finished small tube diameters such as Ø30x10mm. Thanks to the benefit of the patented IGBT technology that the EFD Induction welder utilises, they have reduced downtime and achieved maximum speed and thickness capacity.

In May 2019, Borusan Mannesmann commissioned a new stretch reducing (SRM) pipe mill at its Gemlik facility in Turkey. The plant produces hot formed special pipes for API, mother tubes for OEMs and for the automotive supplier industry in Turkey and the rest of Europe. The fully automatic continuous production line produces a mother tube shell of 88.9mm with wall thicknesses up to 10mm. “The decision to purchase another Weldac was based on a number of important factors,” said Gemlik Automotive factory manager, Ihsan Özgür Turhan. “It was essential that we had high reliability and efficiency as well as the welder’s ability to continue running through any short circuit or flashover in the welding area. This was critical, as a stoppage on an SRM mill, where long

length mother shells are produced, can be a very costly affair.” Originally, Borusan Mannesmann had chosen a 600kWWeldac for the newmill,
