to 650°C, and pipes are processed at up to 100mpm. Maximum yield strength is 1,180 MPa (171,145 psi). The 6CR Series API straightening machines consist of six concave rolls mounted in three pairs, vertically disposed and supported by base and crown sections held together by substantial steel columns. The top and bottom rolls can be driven by individual gear motors or large gearbox and universal drive shafts, which permit the angular and vertical adjustment of each roll. The rolls are quickly and easily adjusted angularly, to provide line contact between the tube/pipe and roll over the maximum effective length of the roll profile. This gives support to the tube/pipe over its length as long as possible and enables tubes with a very thin wall to be straightened without being damaged. In order to process upset-end pipe, the 6CR machines are designed with the ability to open each straightening pass automatically to allow the larger diameter upset end to pass through the machine unrestricted. They are engineered to automatically close immediately onto the pipe body after the upset end passes, allowing the machine to straighten the full length of the pipe body. Another design feature incorporates all of the upset movements into the top passes of the machine, eliminating the need for maintenance access to hydraulic cylinders in the base of the machine – an area typically flooded with scale and water. A quick-opening hydraulic relief circuit has been added as a safety measure to protect the rolls and bearings. Fives Bronx’s COMPASS computer- aided setting system utilises the latest in industrial electrical and electronic technology to provide consistent product quality and throughput capacity. With the COMPASS system, machine set up times for a size change are reduced to less than three minutes, while its data collection and storage is vital to the producer and end user when processing such sensitive and critical components.
