Electrical upsetters for tubes

ThE WorLdS LEAdIng SuPPLIEr of:

CEMSA has announced a new series of electrical upsetters for use by manufacturers that have to upset tubes/pipes mainly in drilling/perforation sectors. This technique is made possible by a new design of the front of the existing model RIO 100 SC SP, where a special clamping system, new current carrier contacts and the “in dies” more powerful forging press, hold and move the tubes automatically. The accuracy along the full process is guaranteed by a sophisticated, but easy-to-use, control system.

PIPE CLAMPS

Special care is devoted to control and monitoring the heating progress and the forging speed in order to keep micro- structural grains within the international strict limits fixed for the related applications. These new models can be equipped either with single phase or with three-phase DC dedicated transformers, designed for continuous service. Sizes of the tubes for “in-dies” upsetting will depend upon the relevant thickness. Productivity will be again depending on the solution chosen and will be confirmed on dedicated offers.

RAFTER Equipment Corporation has shipped a model RT- 7000 seam orientation unit (SOU). The machine will be used by a major North American tube producer to hold the weld seam directly underneath the seam annealing inductor. The SOU is sized for pipes up to 8.625" OD x 0.375" wall. Pipes sizes above this diameter up to 16" OD can be passed through the unit. Rafter manufactures tube mills and pipe mills, roll forming machines, cut-off machines, auxiliary and other related tube and pipe mill machinery.
