Danieli Centro Tube has recently developed FRT™ (four roll technology) – new flexible equipment for the sizing-finishing process in seamless pipe production. Among other benefits, the technology provides better outside diameter tolerances and wall thickness distributions. Also higher outside diameter reduction per stand can be performed. The first operational prototype unit comprises three 4-roll stands. It was installed in the R&D laboratory at the Danieli headquarters in Buttrio (Udine), Italy. The equipment was introduced to the market during an open day on October 4, 2011.
