Pipe mill bending rolls for complex needs PIPELINE and energy infrastructure companies face huge operational challenges. Pipe production is an area of such complexity that only companies with years of experience and highly technological backgrounds can be trusted to reliably design and provide pipe-manufacturing machines suitable for the most challenging projects. and are fitted with three rolls in thermally treated steel alloys. HAV-2P long bending rolls are designed for rolling plates up to 45mm thick, suitable for producing pipes up to and over 18m long, complying with the customer’s specific technical and roundness tolerances, and offering a finished product that meets API standards.

range of diameters and thicknesses that can be obtained by rolling. To further increase the production speed and automation the company proposes, along with the HAV-2P pipe mill bending roll, an accurate post-bending machine that prepares the pipe for welding, and a series of outboard motorised guide rollers that control the movement of the pipe from the HAV-2P to the post- bending machine and successive working stations, achieving a fully automated manufacturing process. Faccin has more than 50 years’ experience in the design, manufacture and commercialisation of plate bending rolls, profile bending machines and dished head lines, as well as special machines that include ship frame bending rolls and presses, and plate straightening machines.

Faccin SpA states that it has been a reference point throughout the years for its expertise in designing and manufac- turing special machines, standard and customised, for the production of pipes. In order to meet specific production requirements in the industry, the company offers the HAV-2P series of NC-controlled pipe mill bending rolls that are able to support the production of pipes, delivering productivity, repeatability and automation of the entire manufacturing process. The pipe production bending rolls are constructed with a sturdy electro-welded structure

The rolls are moved independently – the top roll moves vertically, the lower rolls move horizontally – which allows the power of the machine to be fully exploited, depending on the various thicknesses to be rolled. To offer high performance in the production of long pipes with relatively small diameters, the lower rolls of the HAV-2P are supported by backups for their entire length. The top roll is preloaded to compensate for the flexion during plate bending, and may be replaced quickly to extend the

Double bending system for flatness NINGBO Powerway Alloy Material Co, China, has chosen Danieli Fröhling foil-rolling technology for its third-phase expansion project. To be installed in Ningbo, Zhejiang Province, eastern China, the new 20-high cold finishing mills will roll a wide product mix of copper alloys, from soft pure copper to hard phosphor bronze. Strip dimensions will range from an entry thickness of 1.2mm down to a minimum finish thickness of 0.03mm, at a maximum strip width of 650mm. The core equipment, based on Danieli Fröhling technology, will be manufactured in Danieli workshops in Meinerzhagen, Germany. The twin-housing type mills will be equipped with the patented intermediate-roll double bending system for improved strip flatness and direct hydraulic roll-gap control for high-precision thickness performance. The mills will be capable of using a large range of work-roll diameters, from 37 to 80mm, in order to achieve efficient and economic rolling performance for the user. The copper-alloy strip produced by Ningbo Powerway Alloy Material Co will be mainly used for aerospace, high-speed trains, solar energy, telecommunications and the electronics industry. Plant start-up is expected by the last quarter of 2020.
