The dedusting plant is designed to have extra explosion relief between the filters and a non-return valve fitted in the pipework system. The pipework elements were therefore designed in part with a loose flange connection. The components used in the modular pipework system in 1.5 mm and 2 mm wall thicknesses range from pipes and special fittings, such as bends, forks, segments and cone pieces, right up to manually operated throttle valves and shut-off valves in a powder-coated finish. These system components were assembled quickly and easily with pull-rings to give a sturdy construction.
