NOVA Hydromet offers a wide range of options for blast tubes and choke tubes for slurry letdown, as well as blast spools for vent letdown. These products are custom sized to produce the desired flow and letdown characteristics using first principles mathematical modelling of flashing multiphase flow.
Proper blast tube geometry can drastically reduce letdown plume kinetic energy. Each tube or spool is custom fabricated to interface seamlessly downstream of NOVA’s angle control valve. Custom self-regulating configurations are also available. NOVA will recommend ceramic or cermet lining appropriate to the application, sourced from our network or trusted suppliers.
