Heat exchanger cleaning

Cleaning of inner walls of pipes and tube space is performed by nozzles, selected by considering tubes diameter, thickness and nature of impurity. Reactive power of the water jet by means of location and orientation of holes in nozzles enforces the nozzles, driving them forward and rotation (in rotating nozzles). When using nozzles with a front jet or two intersecting front jets, the material in front of the nozzle is also destroyed. Nozzles can be used with hoses (flexible peaks) as well as with hard-peaks. Some nozzles, having a predominance of frontal jets and requiring forced feed may only be used with hard peaks.
