Parker Hannifin has launched the Parker HPF high-performance mechanical flange system for machines and installations with a working pressure up to 420 bar. This meets the increasing requirements of the press construction, injection moulding and mobile work unit industries. It contributes significantly to a reduction in assembly time and costs because it dispenses with the need for error-prone and time-consuming welding processes. Furthermore, the HPF system has outstanding high pressure and vibration resistance. System performance is underpinned by DGUV certification, which has tested the use of HPF in hydraulic equipment used on injection moulding machines and hydraulic and mechanical presses.
The HPF system is a positively locking connection system. In industrial applications it provides the ideal replacement for welded tube connections subjected to high loads. The HPF system consists of a flange, an HPF insert, a steel locking ring and seals on both port and tube ends to ensure a gas-tight connection. The system is suitable for use on steel tubes from 25 to 150 mm, with tube wall thicknesses up to 20 mm. The associated steel components are supplied with environmentally-friendly, corrosion-resistant Cr6-free surfaces. Flange sizes range from 1,9 to 12,7 cm and are available in accordance with ISO 6162-1, ISO 6162-2 and ISO 6164 standards. Tube flaring is effected in a tulip shape and has no sharp edges. Uniform loading of the surfaces in the whole flange area is achieved with this technology, resulting in very high break resistance.
