With about 350 straightening machines built in its history, Cartacci is definitely one of few companies in the world that can boast such an important reference list. The important experience accumulated over the years now has formed basic principles of straightening machines with ten rolls of automatic configuration: once characteristics of tube are introduced into the programm, the machine calculates by itself setting parameters for the straightening process. This setting is memorised by the machine in order to allow the operator to recall it easily for next production run. The presence of ten rolls also allows an extremely versatile setting: it is possible to achieve five different settings, each corresponding to the quality target to be reached depending on physical characteristics of the pipe to be straightened. A further important innovation, obtained thanks to sophisticated operating logic and advanced technological solutions, was then the introduction of a new family of straightening machines designed for “upset” tubes: the fast opening / closing of each pair of rolls allows for an efficient passage of each “upset” configuration, with maximum straightening capability on every length of tube. The straightening machines made by Cartacci combine sturdiness with precision setting: the perfect balance between mechanical and electronic design, ensuring straightening machines made by Cartacci satisfy a range of high performance applications.

Coupling between the robustness and the precision of positioning: quality on tubes.

Another important innovation realized by Cartacci team is the building of a “new family” of straightening machines, destined to work on API products, in cold or hot conditions, in respect of API 5CT, 5L, 5DP. These machinery can work also “drill pipes”: thanks to a sophisticated running logic and thanks to advanced technological solution, passed through tridimensional analysis realized in cooperation with an important Italian university, these machinery can let pass trough the rolls upset pipes in continuous work, without stopping the cycle. The very fast opening / closing of each roll at the arriving of the upset end of the tube gives the possibility to work strictly on the normal body of the tube itself, straightening it along all its length. The same technical aspect has been used into a second plc logic, in a way that the machinery can prevent completely from any
marks at the ends of the tube. These straightening machines are often used after heat treatment, in hot conditions: tubes pass through the machine at a range of temperature between 500÷650 °C (930÷1200 °F). Also in this case, only the advanced studying on the materials to use and their heat treatments have given the result to supply machinery with very high performances. Cartacci straightening machines distinguish themselves for the coupling between the robustness and the precision of positioning; the balance between mechanical and electronic design gives the result to obtain the very high performances required on API products.

Among new types of machinery that has been recently designed by Cartacci there are also the straightening machines for bars. The consolidated experience of Cartacci in design of straighteners for tubes allowed the construction of straightening machines for aluminum and steel bars used for diversified sectors such as in the energy field (boring rods for the oil facilities). The structure of the machines for bars is similar to that used for tubes with the appropriate hardening of the general frames, considering the overall dynamics developed by working on this product. The setting of the machine has an automatic configuration: once diameter and yield strength of the bar are introduced into the programm, the system calculates by itself the setting parameters necessary for bar’s straightening.
