Devices and accessories that use a high-pressure water flow to achieve cutting or cleaning purposes are called water jet equipment. As a green technology, water jet never produces harmful waste. Water jet technology is the best solution to clean pipes, tubes, facilities, and condensers, or to remove their sediments quickly. Since the working pressure and the type of equipment vary, in order to select the proper equipment for washing and removing sediments, considering the sediment type and related operation is the most appropriate method. It should be noted that it is not always necessary to use the highest pressure for sediment removal operations.
