Flange system gains approval for marine applications

Motion and control technologies supplier Parker Hannifin has announced that its mechanical flange system for machines and plants with working pressures of up to 420 bar high performance flange system has gained DGUV approval for marine applications.

The DGUV approval certifies the use of Parker’s high performance flange in hydraulic systems for injection moulding machinery as well as in hydraulic and mechanical presses.

This range of products meets the growing requirements of construction, especially for the navy, press manufacturing, injection moulding and mobile work equipment industries. At the same time, the high performance flange system significantly contributes to a reduction in assembly time and costs because it dispenses with the need for error-prone and time-consuming welding processes.

The Parker high performance flange system also has outstanding high pressure and vibration resistance.

The new flange is a form-fit connector system. It complements the proven product range of pipe connector technology with EO2 FORM and F37 for outer pipe diameters from 25 mm. In industrial applications, it provides the ideal replacement for welded pipe connections that are subjected to the highest loads.

The high performance flange system consists of a hardened flange with lock ring contour, a high performance flange insert (with O ring recess or as a flat-sealing version) and seals on both port and pipe ends to ensure a gas-tight connection.

The system is suitable for use on steel pipes with outer diameters of up to 150mm. The associated steel components are supplied with environment-friendly corrosion-resistant properties.

Flange sizes are available in accordance with ISO 6162-1, ISO 6162-2 or ISO 6164 standards. Pipe 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 high break resistance.

The forming process is carried out using Parflare machinery specially developed for these products and providing hydraulic axial compression.
