Technical Examples

A substantially uninterrupted flow of a pressurised abrasive slurry is maintained by successively charging each of a plurality of vessels V1, V2 with an abrasive material while discharging an abrasive slurry from another of the vessels at a common outlet 2. The vessels connect to the common outlet via respective outlet valves OV1, OV2 which are closed to isolate vessels not discharging slurry. The outlet valves are not opened or closed unless there is substantially no pressure differential across the valve and substantially no flow through the valve. In a preferred arrangement, a high pressure pump 1 feeds a carrier fluid such as water to the vessels via respective inlet valves IV1, IV2. Before an outlet valve is opened or closed, any flow through the outlet valve is stopped and the pressure differential across the valve is equalised so that the outlet valve can be opened or closed without any abrasive flow through the valve.
