Launch of Canadian spiral pipe plant and training on-site by Schuler

IN less than five months, Schuler and its customer Evraz launched a spiral pipe plant in Regina, Canada. In addition, the forming technology specialist spent three weeks training maintenance staff for software and hardware about the line and its components. The line was previously installed in the USA, before Evraz bought it and relocated it to Canada. For the modernisation process Schuler also supplied the coil cart and decoiler, as well as all roller beams of the forming station. At the heart of the decoiler are two coil stands, each with two servomotors and proportional valves. The line will be used to produce spiral pipes measuring 12 to 24.3m in length, with diameters of 608 to 1,625mm. The pipes will have wall thicknesses of 6 to 25.4mm and weigh up to 24 metric tons.

ranging from 244 to 711mm OD (9 5 / 8 " to 28"). In terms of the finished product quality (ovality, eccentricity, straightness and reproducibility), the new mill’s performance targets were reached just after the equipment start up, and then followed in steps by the productivity and availability goals. The machine was built, assembled and pre-tested in the workshops at Danieli’s headquarters, and installed during an outage of approximately eight weeks for demolition, excavation, civil works and erection. Innovative prefabricated foundation modules and

erection techniques were adopted to achieve the short shutdown targets. According to Dr Ulrich Menne, chairman of the management board of Vallourec Deutschland GmbH, “With the investment in a new CRM here in Düsseldorf-Rath we want to expand our product range in the direction of higher quality premium materials with higher resistance to deformation, in particular in regard to alloyed and high-alloy materials.”

DANIELI has reported that Vallourec Deutschland (VAD) achieved excellent performance from the beginning, operating the new Danieli cross- rolling mill. After just two months of performance testing, VAD released the mill acceptance certification. The cross-rolling mill (CRM) supplied to VAD is a newly designed machine developed by Danieli Centro Tube to meet VAD’s demanding requirements, which include the flexibility to roll carbon, alloy and high-alloy carbon steel grades, starting from 400 to 850mm OD ingots. The finished products are tubes
