Large plate roll deliveries

THE expansion of Davi in Latin America counts a new success, with the sale of a large variable-axis plate roll. The machine, which is capable of rolling 10ft wide and 3 1 / 8 " thick plate, has been sold to the largest pressure-vessel manufacturer in Ecuador, and is claimed to be the largest plate roll in operation in the country. The customer is reacting to the sector’s trend towards using high resistance steel, an aspect that is making it imperative to update fabricating equipment locally with higher rated machines. The purchase of the machine confirms the trend. “Once again our innovative variable axis plate roll has been chosen due to the flexibility obtained by horizontal movement of the side rolls and to the upper roll which also moves vertically,” commented Orazio Davi, president of Promau. “The result for the customer is virtually perfect flat ends making it suitable for pressure vessels manufacturing at a very high quality and productivity.” Davi has also partnered with other customers in South America. Recently these new partnerships resulted in the sale

of another 4-roll Davi machine in Costa Rica. This machine can roll 10ft wide and 3 7 / 8 " thick steel plates, and was sold to the largest hydroelectric company in the country. The Central and South American region is continuing its economic growth and has an ever-increasing need for power. The majority of this increased power demand will come from new hydroelectric resources. These installations utilise a substantial amount of steel pipe made from high resistance, thick walled, steel. “Davi’s 4-roll machine has been chosen by this prestigious customer also due to the fact that our machine requires only a small amount regular maintenance,” said Mr Davi. “It does not even need greasing, thanks to the patented technology of the scale free, self-lubricating planetary guides, compared to the previous generation technology plate rolls that still use linear friction guides.” The choice to procure the Davi plate roll was in part made due to the company’s ability to offer a full turnkey system. The machine

Davi’s MAV bending machine

was installed by Davi technical personnel, who took care of the machine assembly, installation, runoff, pre-programming and training of the customer’s operators in operating a modern plate rolling machine and the techniques available with the Davi machines.
