It is a fact that tubes of boilers, heat exchangers, condensers and others heat transfer systems, accumulate deposits during operating period.
The formation of hard or soft scales on the tube internal surface can reduce the heat exchange flow through the tube wall, because these scales are generally thermal insulators. In addition, a build-up of scale on a tube inner diameter gradually decreases it’s section area thus reducing the fluid flow. Both effects lead to a lowering efficiency of the thermal equipment. Besides is the possibility of damage to the tube due to the chemical nature of some deposits that can be corrosive to the tube material.
One can conclude that, in order to maintain efficiency and prevent permanent damage, the tubes of heat transfer equipments must be kept clean and scale-free.
HANNA offers a comprehensive line of tube cleaning tools and accessories that meets the requirements of many classes of heat transfer systems and are suitable for a variety of deposits usually found.
