The Jacob pipework used is installed outdoors and is therefore exposed to the elements. To increase its resistance to corrosive processes, it was decided to use stainless steel. Another reason for this choice of material lay in the decontaminability requirements that applied, and which galvanised materials are unable to meet. Pipework sizes of up to DN1250 were used for this project and were installed with loose flange connections with flat gaskets made of EPDM. The pipework layout comprised lengths of 1980mm and incorporated conventional press-formed components (90°,45°, 30°, 15° bends, T-pieces, Y-pieces, cones).
