Jetting velocity breaks sound barrier

A Hughes Pumps high pressure water jetting unit is used by South Korean water jetting contractor Sungdo Co at the some of the country's major oil refineries. It is delivering a water jet at 1400 bar, producing a velocity of 477m/s or Mach 1.4.

The hardest of scale is removed from tube/pipe walls without damage to the steel substrate. Used for shutdown maintenance, including pipe, vessel and heat exchanger tube cleaning, the unit uses multiple flexible lances with rotating nozzles to clean 100% of the tube wall. Only plain water is used.
