wall thicknesses and exceptional dimensions, in carbon steel, alloy steel and stainless steel. Starofit’s stock programme features more than 50,000 different dimensions and 100 material grades, and the company recently invested in its holdings of low alloy material grades, in order to offer a comprehensive stock of elbows and fittings in WP11 and WP22 from wall thickness series STD up to XXS.

Starofit will exhibit at various trade fairs in Europe this year, including BORU Fair 2015 in Istanbul, Turkey; Stainless 2015 in Brno, Czech Republic; and Stainless Steel World Conference & Expo 2015 in Maastricht, Netherlands.

The company has a permanent fittings stock of 6,500 tons, which enables it to provide prompt response to customer requests. The holdings range from a large stock of ASME and EN/DIN standardised products, to highly specialised elbows and fittings with extreme

Clamping technology The conditions and requirements in manufacturing technology are becoming increasingly complex, and include factors such as flexibility, shorter set- up and production times, increase of operational safety and efficiency. At the same time, users are looking for simple and cost-effective solutions.

Especially in the manufacturing process of steel parts in presses and punches, the clamping elements provide a high degree of safety through low hand forces during tightening of the necessary tools and equipment. The clamping systems are suitable both for original equipment and as retrofit items.

clamping forces up to 350KN are available. The hydraulic supply is only required during installation and removal of these products; in operation, the axial force is kept purely mechanically, by a disc spring assembly. This clamping technology offers an alternative to simple workholding equipment such as clamps and brackets, as well as to semi- and fully automatic clamping elements, with their elaborate power supply and control systems.

In the field of mechanical and hydro- mechanical clamping elements, Enemac offers flexible and reliable clamping technology with various power clamping systems and hydro-mechanical spring clamping systems.

Clamping elements from Enemac

The range runs from controlled clamping with torque handle ESBS/ESBT with a nominal clamping force of up to 40kN, to power clamping nut ESB with up to 200kN, and type ESD with up to 180kN. For these products, relatively low torques are converted by an internal gear ratio in high axial forces. In the case of the power clamping screw ESS, the tightening torque is converted by a wedge clamping system in clamping forces up to 250kN. Thread sizes from M 36 to TR 100 are available. With the ‘spring clamping cylinders’, a combination of disc spring and hydraulic,
