Higher production in a smaller space EFD INDUCTION has introduced its Weldac welder to the only steel tube and profile manufacturer in Ireland, Sperrin Trading Services Ltd (STS), enabling the company to increase its production output and free up valuable space. wall thicknesses up to 6.3mm. Last year, STS upgraded the drive systems of its Kusakabe tube mill, which meant the company needed to replace an old thermionic valve high-frequency welder.

was a much smaller footprint compared to the old system, which has freed up space behind the mill. It has also enabled them to increase production output.” Damien Convery, managing director at STS, added: “The new Weldac has only been in operation for three months, but we can already see reduced energy consumption with increased line speeds. The controls are simple and easy to use for our operators and weld bead quality is more even and consistent.”

“We presented the Weldac technol- ogy to them, as it would be a significant upgrade of efficiency, reliability and flexible delivery of stable weld power,” added Mr Bond. “We produced examples of energy savings based on STS’s existing installation, production hours and energy costs in order to justify investing the money. The new 250kW Weldac

“STS had been a long-term customer of EHE Consumables, so we had a good existing partnership with them,” said Peter Bond, EFD induction sales manager. STS produces pipes from 22mm to 125mm diameter, squares from 25mm x 25mm to 100mm x 100mm, and rectangles up to 100mm x 50mm, with

the Antirust system is able to detect the speed variation and to adjust the correct RPO quantity automatically and proportionally. Giovanni Amato, sales director and founder of DieTronic Srl, explained: “The special design of DieTronic systems was specifically developed to enhance the lubrication quality, by solving the problems of environmental contamination as well as fluid and energy consumption.” As a standard configuration, the whole range of products of the Antirust series are provided with one or more extractable spray boxes – according to the tube or profile dimension, a flow control that allows the check of the correct operation of each individual channel, a suction system to reduce the oil mist dispersion, and a recovery filtering unit to collect unused fluids.

DIETRONIC, a company that specialises in the production of spray systems for the automatic and controlled application of rust-preventive oil (RPO), has found a solution to its customers’ number one problem – white rust. According to the company, its customers all agree that when dealing with manufacturing and trading of tubes and profiles, the one common enemy is white rust, which is a corrosion process that can occur on galvanised and pre- galvanised steel under certain exposure conditions. This type of corrosion can happen especially during material transport and outdoor storage when there are rapid changes in temperature. Most frequently, it occurs when a freshly galvanised material is placed into contact with water, or hydrogen dioxide. As long as the surface is wet, the white rust could be transparent and would be visible only when the steel dries. This

phenomenon is not only harmful to the steel appearance of tubes and pipes, but, if neglected, it can also lead to significant damages to the galvanised coating. DieTronic’s LCP-Antirust line is entirely automatic and specifically designed to set the desired protective fluid’s dosage through a user-friendly touch-screen panel, thus applying the RPO quantity (in g/m 2 ) in a controlled and constant manner, with a claimed fluid consumption reduction of more than 70 per cent. As an additional feature, when the process line slows down or speeds up,

Uniflex introduces HM crimpers UNIFLEX has released its latest HM crimpers, which are attempting to set new standards for quality and efficiency. The HM 480 production press has an innovative design, which was created especially for special sizes of the industry, as well as pressing force up to 4,500kN. Uniflex said: “As well as user friendliness and a long service life, the HM 480 combines high productivity and quality with outstanding ergonomics and a long service life. It offers an opening stroke of more than 150mm and an opening diameter of 380mm (without dies) so can therefore be used to crimp industrial hoses up to 8" with ANSI flanges and pipe fittings up to 12" without having to remove the dies.”

The HM 480 is controlled through the Control C.2, a bespoke control unit of Uniflex, and apart from hydraulic hoses, the machine can be used to join reinforcing steel, steel cables, ropes and insulators with forces up to 4,500kN.
