See more at : http://www.dunnheat.com/ Heat exchanger tube cleaning can oftentimes be very tedious because the very design of many exchanger tubes can make them hard to clean. The design of these tubes can be convoluted or quite curved or bent into a variety of shapes. This can make the usual methods of tube cleaning, especially using water jets, less useful. All the curves, for instance, can slow the water down, reducing its usefulness as regards removing contaminants, especially if these contaminants are encrusted or otherwise stuck to the walls or sides of the tubes. In addition, as water slows down as it curves, many contaminants can easily be deposited in certain areas. Therefore, traditional methods of tube cleaning may not be too effective, if at all, when applied to heat exchanger tubes.
