Straightening machine with ten rolls

diameters ranging from 1.5" to 5": the line is composed by one straightening machine mod. RDT10V2 with ten rolls and completely automatic setting, one cutting line with multiple cut by five heads (for the maximum versatility of cuts setting) and by one packaging machine mod. IMPC130 with completely automatic setting: inserting the characteristics of wanted bundle’s form, within a few seconds the machine reaches the set-up needed, without requiring the operator to set the long manual operations. Once more, evidence of technical development and constantly improving of the quality, Cartacci is placed on a high technological quality level even in design of packaging machinery.

diameters from 2" to 9". The equipment is composed by one drawing bench of 150 tons, one automatic straightening machine with 10 rolls mod. RDT10V3/4 directly connected with multiple cutting line. The whole line ranks among the most advanced lines that are currently used in the production of drawn tubes in Brazil. Cartacci is also present on the Indian market with the installation of No. 3 drawing benches and No. 2 straightening machines (all from the Cartacci brand) that, after not being used by one Italian customer following the renewal of all machinery, have found a new use on the plant of an important Indian tube producing company, reflecting the reliability of Cartacci machinery even more than 30 years after their initial installation. Remaining on the Italian market, Cartacci has recently started a new complete line for drawn tubes with

CARTACCI Ltd has recently acquired important contracts in major markets including the USA, Brazil and India without neglecting the Italian market. For the USA market it has built one well tested straightening machine model RDT10V3UP with ten rolls and completely automatic setting. Placed in a moulding tube line it will process API tubes of different diameters range from 2" to 7". With this type of product Cartacci has acquired considerable experience during the last few years. The system for rapid and automatic setting (machine set system), based on a perfect synchronisation between the mechanics and electronics, guarantees a high optimisation of production changes, essential for mills with high productivity such as this line. For the Brazilian market, Cartacci is building a big line for drawn tubes production, which is characterised by the wide range of processed tubes with

Normalising pipe weld seams EFD Induction has unveiled an innovative control system for normalising weld seams to API standards. According to Per Ødesneltvedt of EFD Induction’s research and development centre in Norway, the new system provides three valuable functions. “The first is ultra- accurate power control and optimised power inputs – essential when working with narrow tolerances. The system also supervises a power injection function for quick power ramp-up, which boosts productivity by minimising scrap.” ensures that the coils track the seam. “With orbital tracking of the seam,” said Mr Ødesneltvedt, “the system can move coils to plus or minus 15°.” The system also handles unwanted movements of the pipe: “Not only can the seam deviate, but the pipe itself changes position. That’s why our system has a centre-line offset compensation function, to ensure the coils are always in the right position.” The new control system

Quality control is enhanced by defect detection and quick coil release features.

The third function covers safety, quality and communication features. The system also collects quality control data for each batch of pipe normalised.
