Ngungaju Plant at Pilgangoora - Complete Tailings Dropper System

Design engineer DRA Global. The Ngungaju team wanted a complete tailings dropper system, rather than source multiple hoses, clamps and pipe, then piece them together. They didn't want the parts arriving on site at different times causing delays in construction. So, in collaboration with DRA Global, they got in touch with our piping specialists.
